The best fire protection for wood. Fire and Bioprotection: How to choose wood treatment products. Fire-retardant composition for wood

If you decide to build a house with your own hands, then you need to think in advance about how to process the wood. Many people remember this when, after a few years, they begin to notice traces of the hard work of wood-boring beetles or become eyewitnesses of how their creation turns into ashes, eaten by flames.

But all this can be avoided if you think in advance about how best to protect the wood from all factors. Currently, such means exist, for example, fire and bioprotection for wood. Let's figure out what this composition is, what it is used for and what benefits it has.

What is fire protection?

Experts who study the properties of wood believe that it is best to use protection that will protect against the effects of several negative factors. Such compositions are now commercially available - this is the so-called (fire-bioprotection), which performs several tasks at once:

It should be noted that treating wood with fire-bioprotection is not capable of protecting 100%, but even such an effect significantly extends the life of a wooden structure.

Type of fire bioprotection

To reliably protect wood from the effects of negative external factors, it is not enough to know the rules for choosing compositions. Great importance knowledge of properties and features of use plays a role. Fire protection for wood is available in two forms:

The difference between them lies in the aesthetic quality of the processed wooden surface. If you use impregnation, it practically does not change the texture of the wood and its smell, but a coating in the form of paste or putty worsens the appearance and gives a certain smell. Because of this, such compositions are most often used in places that will be subject to additional finishing.

Fire protection for wood is distinguished by its ability to dissolve, therefore the following are distinguished:

• Water soluble.
• Organically soluble.

Varieties: basis of composition

If we consider the chemical formulas of fire bioprotection, the division is as follows:

• Saline.
• Non-salt.

The second variety began to be used much earlier. It is based on salts of carbonic, phosphoric and boric acids. It has some advantages:

• Does not change the appearance of the tree.
• Provides reliable adhesion to wood fibers.
• Has a high degree of protection.
• It is possible to paint the top.
• This composition retains its properties for more than 10 years.

Many believe that this is the best fire protection for wood, since it has no toxic properties and is completely safe for humans.

Salt compositions are lower in cost, but have their disadvantages:

• Shelf life is short.
• Not a very high degree of protection.
• A large amount of surface treatment is required.
• There is no option to paint.
• Easily washed out with water.

All these disadvantages force the use of such a composition indoors.

Fire protection resists fire

If we consider this fire-bioprotection ability as resistance to fire, then such compositions are divided into two groups:

Nature of processing

Different fire protection for wood implies different types of processing.

1. Consistent protection is impregnation of wood with fire retardants, and only then with antiseptic compounds.
2. Combined processing is a new method that reduces time and increases efficiency, since the wood is immediately impregnated with protection that has a combined effect.

It should also be noted that now manufacturers produce compounds that not only protect wood from negative effects, but also extend its service life and maintain an attractive appearance for a longer time. For example, fire and bioprotection of Senezh wood meets all sanitary and environmental requirements, therefore it can be used for any wooden structures both indoors and outdoors.

The need for comprehensive fire and biological protection

There are situations when it is simply necessary to use compounds with complex effects. This protection is required:

Complex fire-bioprotection for wood, reviews confirm this, reduces the risk of ignition several times. Even if a fire occurs, the active substances of the protective composition greatly slow down this process. Buyers claim that protective impregnation can extend the life of an object by more than 20 years.

Efficiency of protective compounds

If, when choosing a protective composition, the question is which fire-bioprotection for wood is better, then the first thing you need to pay attention to is the effectiveness group; it must be indicated on the label.

Depending on the purpose of use, you should choose between the first group and the second. If it is necessary to make wood difficult to ignite, then you can choose class 2, class 1 preparations will make the wood difficult to burn.

By the way, if you choose means for impregnating wooden structures inside a building, then fire regulations allow only first class use.

If there is a composition of the second group, then by applying several layers, you can increase the degree of protection and obtain fire resistance at the level of group 1. You can do the opposite, if instead of two layers you apply one layer of class 1 impregnation, you will get group 2 fire resistance of wood.

This fact must be taken into account in order for fire bioprotection to have the desired effect.

How to calculate the amount of fire protection?

If we consider the economic indicator, it is important to take into account the consumption of impregnation per square meter. This fact will affect the total cost of the composition required for processing.

For example, if you use the Senezh salt composition, then about 600 g of impregnation per square meter will be required to apply 6 layers, then 1 protection class will be achieved.

Non-salt impregnation of an expensive brand will provide reliable protection with a consumption of only 250 grams per square meter.

When purchasing, it is also worth considering how deep the impregnation can penetrate. There are two categories of compounds:

• Superficial, the composition penetrates no more than 6 mm.
• Deep penetration impregnation will protect wood to a depth of more than 12 mm.

If we talk about ease of use, surface impregnation wins here, since it can be applied with any tool and does not affect the strength of the wood. The appearance of wooden structures will depend on the coloring ability of the composition. It is better to choose colorless ones, then the aesthetic characteristics of the tree will not be affected.

Application of fire and bioprotection

In order for the protection to give the desired effect, it is necessary to follow a number of recommendations for its application:

If you follow all application rules, wooden structures will be protected reliably and for a long time.

It is also necessary to correctly apply the compounds to wooden structures. Typically, sprayers, rollers or brushes are used for these purposes. To enhance protection, apply several layers at intervals of 30 minutes. The desired effect will not be obtained if the wood was previously treated with water-repellent or film-forming compounds.

Well-known brands of fire protection

When choosing fire protection for wood, you should not rely only on the brand name. This does not always guarantee excellent quality and reliable protection. The technology for manufacturing such compositions is almost the same for all manufacturers, but the quality may suffer due to the use of low-quality components.

Among the salt impregnations, the following well-known brands can be mentioned:

Their cost is low, up to about 70 rubles per kilogram.

• Impregnation of the second generation "Pirilax";
• "Neomid".

Their price is already much higher and reaches 320 rubles per kilogram.

Where can fire bioprotection be used?

Antiseptic, fire-bioprotection of wood can be used to treat only objects under construction; it is also possible to impregnate wooden structures that have previously been subjected to antiseptic treatment.

Modern compositions will not only protect the tree from mold fungi and wood-boring beetles, but will also allow it to maintain an attractive appearance for a long time, protecting it from cracking.

Currently there is good opportunity When building your own home, you will make sure that the wooden structures are not damaged by bugs, mold and remain attractive for a long time. You just need to purchase the necessary impregnation and carefully process the material.

Wood is the most environmentally friendly building material. A wooden building is warm in winter, cool in summer and has a special, healthy microclimate with a self-regulating humidity level. But, this material, like any organic matter, is susceptible to fungi, bacteria, harmful insects and ignites very easily.

Therefore, experts recommend using wood antiseptic as a protective agent.

Types of antiseptics

Antiseptics are water-repellent compounds designed to protect lumber from microorganisms and insects that feed on wood.

Wood, of course, is best treated with them in advance. However, if it was nevertheless infected, a high-quality drug can stop its further destruction.

Wood antiseptics are divided into four groups according to their composition:

• Water soluble;
• Oil based;
• Based on organic solvents;
• Combined.

Water-soluble compounds are preventive for those structures and wood coverings that do not come into direct contact with moisture.

Solvent-based compositions capable of protecting wood both outside and inside buildings. This antiseptic forms a dense film with good characteristics adhesion and moisture resistance.

Combined formulations in addition to biological protection, they can reduce the flammability of wood, i.e. They also have fire retardant properties.

As a rule, modern wood antiseptics do not have a pronounced odor. In order for the treatment to be of high quality, the composition must be applied in 2-3 layers.

Remember! Do not impregnate frozen or damp wood, as this sharply reduces the absorbency of the antiseptic.

Treating wood with antiseptic

1. A prerequisite before applying the antiseptic is that the wood is clean and dry. To clean the material, you can use a steel scraper and a suitable solvent.


2. First of all, damaged areas should be treated - the ends of the boards, cuts, cuts, etc.
3. Treatment of wood with an antiseptic should occur at a temperature of at least +5º if it is based on a solvent and at least +10º when it is water-soluble.
4. The relative humidity in the room when working with the composition should be at least 80%.
5. The antiseptic can be applied with a brush, roller or spray.

Wood antiseptic can be applied with a brush or roller

Most of these compounds repel but do not kill insect pests. To destroy them, special preparations are produced, usually alcohol-based. The technique for using such antiseptics is different.

The liquid is poured with a syringe or pipette into the external openings of the passages of beetles and larvae. Then the surface around them is carefully coated.

How to choose the best antiseptic

Among some builders there is an opinion that many antiseptics are an advertising canard: video “The Truth about Antiseptics”

A high-quality antiseptic impregnation for wood should have high toxicity to harmful microorganisms or insects. Based on the level of protective ability, such compositions can be divided into 4 categories:

• ineffective,
• moderately effective,
• effective,
• highly effective.

The preparation must correspond to the level of wood damage. According to this parameter, it can be divided into three groups:

• clean,
• not contaminated lumber,
• having a slightly affected surface,
• heavily infected.

For each of these types you need to purchase a special composition. Also keep in mind that antiseptics are often intended for either internal or external surfaces.

If you need the purchased composition for processing interior spaces, then its packaging must contain an official sanitary and epidemiological conclusion, preferably duplicated by the conclusion of an independent laboratory, about the harmlessness of the solution to humans and domestic animals.

Wood antiseptics intended for impregnation of facades must have good weather resistance.

It is important that the composition is convenient and easy to apply, and if you are going to use any paint material, then be compatible with it.

The best foreign manufacturers of antiseptics

It’s worth starting a comparison of wood antiseptics with the products of the Danish company Pinotex, which was the first to appear on the Russian market in this area. Many experts consider its products to be the best in Europe. They protect not only from mold, fungi, insects and moisture, but also from sudden temperature changes. This allows the use of Pinotex compositions outside buildings.

The famous Finnish company Tikkurila, in addition to paints and varnishes, also produces high-quality antiseptic compositions. They can be used to process both external walls and fences, as well as wooden structures.

The Slovenian company Belinka Base produces the best antiseptics for deep penetration wood. These are colorless primers containing biocides, the purpose of which is to preventively protect wood from blue stains, fungi and harmful insects.

Russian antiseptics

Antiseptics from Senezh

Among Russian companies, Senezh was the first to reach the international level and receive the appropriate quality certificate (ISO 9001). Its Senezh Ecobio antiseptics provide increased biological protection of wood. Can be used independently or as a primer for painting.

"The Tree Doctor"

The worst enemy of wood is white house fungi, which imitate ordinary mold. Until recently, it was not possible to effectively combat them. But such an antiseptic for wood has also appeared: customer reviews indicate that the domestic company “Wood Doctor” has developed drugs that can solve this problem.

"Neomid"

Another Russian company, Neomid, differs from other manufacturers in that it sells antiseptics in concentrated form, and this significantly reduces their cost. Its compositions are produced in compact packages, like a dry mixture.
For initial treatment, the best wood preservative is Neomid 46-bio, as well as Neomid 440.

Video about antiseptic from the Neomid company:

Wood, due to its natural purity, availability, numerous advantages in terms of ease of processing and good operational qualities, from time immemorial it is one of the main materials in the field of construction. However, it also has its drawbacks, which can lead to a decrease in the durability of individual parts and the entire building as a whole. The main “disadvantage” can be considered the low resistance of most wood species to biological damage. The tree undergoes natural decomposition and is a good breeding ground for various forms of microflora and for many insects. To avoid rapid damage to the material, maximize durability wooden parts and structures, lumber must be treated in advance with special means, and then, if necessary, the finished structure must be treated.

Manufacturers offer a wide range of solutions for this purpose, made using different bases- it’s not so easy to figure it out “at once”. That’s why consumers often have a question: which wood preservative is best to choose? To determine what protective compounds exist and which of them are used in a particular case, it makes sense to consider them in more detail.

General classification of antiseptics for wood processing

Antiseptics can be divided into types according to several criteria - these are the components on the basis of which they are made, the area of ​​application of the compositions, and their functionality.

• So, antiseptic impregnations are basically divided into aqueous, oily, organic and combined solutions.

A few words should be said about their characteristics:

- Antiseptics for water based used for protective impregnation wood of any species. For their production, components such as sodium fluoride, sodium silicofluoride, as well as borax and boric acid(BBK3). Water-soluble compounds are most often used to impregnate wooden surfaces, which in the future will not be exposed to intense moisture.

- Oil antiseptics can be called the most popular, since they are able to protect wood from high humidity and moisture penetration into the fiber structure of the material. When applying the solution to oil based on the wooden elements of the building, they acquire one of the rich dark shades.

This type of impregnation does not dissolve in water, since it is based on shale, anthracene or coal oil. It must be remembered that oil antiseptics do not protect wood from rapid combustion, that is, they are not fire retardants. They have a very pungent specific odor, so they are most often used to impregnate the external surfaces of buildings.

- Organic solutions most often used for impregnation facade surfaces. As a rule, they are used in cases where wooden walls planned to be painted, as they create a thin film on the surface, which reduces moisture absorption wood and increases the adhesion of paints and varnishes.

However, it must be said that they are also suitable for processing internal wooden surfaces, so they can be used for pre-processing timber or logs from which walls will be built.

Organic solutions give wood a greenish tint and increase the porosity of the structure. In addition, they can negatively affect metal elements, which are fixed on the facade and will come into contact with its surfaces, so chemical composition may contribute to the activation of corrosion processes.

• According to the area of ​​application, antiseptics can be divided into solutions intended for external and internal works, for dry and wet rooms.

- Solutions for external work. This category includes antiseptics for preparatory and decorative work, which are highly resistant to aggressive influences. environment, such as ultraviolet radiation, high humidity, freezing, sudden temperature changes with a significantly large amplitude. Due to the fact that the compositions very often have a sharp bad smell, they are not recommended for use on internal surfaces.

- Antiseptics for interior works . These solutions are made from environmentally friendly components, they do not have unpleasant odors and do not emit toxic fumes into the environment. At the same time, it must be remembered that for rooms in a house or apartment with different levels of humidity, different antiseptics will be required. Manufacturers always place information about their specific purpose on the packaging.

• In addition, antiseptics are divided into therapeutic and prophylactic solutions:

- Medicinal compositions are used in cases where the wood is already damaged by fungus, mold, rot or insects. However, this solution option can also be used for preventive work. Especially in cases where it is planned to operate wooden structures in an aggressive environment, for example, in bathhouses or bathrooms (showers). They are also quite suitable for preventive treatment of facade surfaces.

- Prophylactic solutions- the most common. It is clear that they are used, as a rule, for processing lumber before the start of construction or during its implementation. Moreover It is recommended to impregnate wood immediately after purchasing it.

Antiseptics can be colorless, that is without changing the natural wood shade, or pigmented, giving surfaces a certain shade. That is, many compositions can be used both as a primer preparatory layer for painting or other finishing, and as an independent tinted decorative coating.

Classification of wood protective compounds by functionality

Antiseptics are also classified according to their functional effects on wood. There can be many reasons for the “launch” of processes of biological damage to wood - this is the lack of proper ventilation, timely treatment with appropriate compounds, improper storage of lumber before the construction of a building, poor-quality insulation of the structure, exposure to moisture on the surface, etc. In addition, many compositions also have a targeted effect - for example, restoring the normal color of wood or giving the material higher resistance to fire.

Whitening antiseptics

To provide protection and at the same time restore the original color of damaged or damaged wood, to “rejuvenate” it, special bleaching antiseptic solutions are used. The most popular of them include the following.

• “Bioshield 1” and “Bioshield 2” - these impregnations are designed to prevent superficial putrefactive processes occurring in wood under the destructive influence of pathogenic microflora. In addition, they are able to preserve the physical and technical characteristics of the processed material, as well as restore the healthy natural color of unpainted wood.

If the wood lesion is on initial stage, then you can use “Bioshield 1”. After the treated surfaces have dried, they can be painted or finished with other decorative materials.

In case of severe damage to the tree by mold or lichen, it is necessary to use the Bioshield 2 product.

Both of these compositions are well suited for processing wood used in the construction of log bathhouses and houses.

• “Prosept 50” is a domestically produced bleaching antiseptic “medicinal” product for wood. The composition perfectly removes foci of biological damage, including gray plaque, restoring the healthy color of the tree in literally 25-30 minutes, preserving its structural structure.

The penetration depth of this composition is 3 mm. And within 12 hours after applying the antiseptic to the wood, it can be painted or glued. insulation material or wallpaper.

"Prosept 50" is an environmentally friendly solution, so it can be used for both external and internal treatment of wooden surfaces. In addition, they are even processed wooden pallets on which food products are transported and stored.

In order for the solution to remain in the structure of the material for as long as possible, it is recommended to additionally coat the surfaces with the preservative antiseptic agent “Neomid 430 eco” or “Neomid 440 eco”. These funds will eliminate the possibility of recurrence of foci of biological damage.

• "Neomid 500" - this whitening antiseptic is similar in its characteristics to the previous product. However, its cost is significantly higher, so it is not so popular among builders.

The solution is an environmentally friendly product and can be used for internal impregnation of wooden surfaces. The product is most often used professional builders for processing wooden logs of bath buildings and residential buildings. Its drying time after application is 24 hours.

• Whitening antiseptics from the Sagus company are water-based. They are designed for radical removal of any type of damage caused by black mold and wood-staining fungus from unpainted wood. Solutions are also used to impregnate logs and timber for the construction of bathhouses and houses.

"Sagus" produces three types of whitening compositions - "Standard", "Profi" and "Light" :

- “Standard” is a solution of deep and rapid penetration into the structural structure of wood fibers. It is used at the first manifestations of mold, the appearance of lichen or moss, as well as darkening of the material as a result of exposure to ultraviolet radiation.

- “Profi” is a composition that can cope with more serious damage to wood. In addition, it is suitable for impregnating surfaces built from mineral building materials (brick, gas silicate blocks, etc.).

Wood is a favorable environment for the emergence and development of colonies of fungus and mold. The risk of their occurrence is especially high if the wood is constantly exposed to moisture. Once a lesion appears, getting rid of it is not easy, since it penetrates the structure of the wood fibers, destroying their integrity.

To prevent this process, a protective composition is used that prevents or stops the growth of fungal colonies. If microorganisms have captured large areas of wooden surfaces, then antiseptics should be used only after therapeutic measures, which are carried out using special means - fungicides.

In addition to protecting against such damage, this type of product can repel insects harmful to wood, which can turn it into dust in a very short time. It should be noted that there are many varieties of tree beetles. But if done on time preventive actions, none of them will be harmful to wooden products.

The most popular ones will be discussed below. protective antiseptics various manufacturers.

• "Senezh" is domestic manufacturer, which supplies to construction market Excellent compositions for wood processing. A wide range of similar products are offered for wooden parts in any area of ​​the building and with various functionality, including purely protective antiseptic action.

Such products include the Senezh Bio solution, which is capable of fixing the natural protective qualities of wood. The compositions are made on a water basis; they well impregnate the wood structure, forming a three-level protective threshold. Fully suitable for both external and internal surfaces of buildings.

In addition to solutions that make the material resistant to mold and tree beetle, this manufacturer produces compounds that make wood more resistant to fire, high moisture and ultraviolet rays.

• "PAF-LST" is a domestically produced antiseptic water-soluble paste made on the basis of fluorine and lignosulfate. The manufacturer promises that the product can increase the service life of wood to 30 years or more.

The paste is intended for processing wood used for the construction of load-bearing and enclosing structures. Moreover, even raw wood can be processed. The preparation is odorless, and when applied it paints the wood a dark pistachio color, creating a rough layer on its surface. This antiseptic option is chosen if the elements it treats are not planned to be painted.

- “Homeenpoisto +” - These are special tablets that are used to prepare a solution to remove mold and prevent their formation. The composition can be used to treat old and new, external and internal, wooden or mineral surfaces.

The treatment process with this substance is carried out before dyeing. The tablets are dissolved in plain water, and then the resulting solution is applied to the surface using a spray bottle. The product is given a certain period for a more intense effect on the affected areas of the material. Then the surface is treated with a brush or foam sponge, after which it is washed with clean water and dried. After drying, the surface must be painted immediately.

- “Homeenpoisto 1” is an antiseptic jelly-like product designed to remove lesions from wooden surfaces and further protect parts from recurrent processes. The solution is made on the basis of hypochlorite, so it is intended for external use only.

MOKKE offers high-quality and reliable antiseptic Russian manufacturer LMB-color. The product is intended for processing wooden facades and other external surfaces. The reliable composition of the antiseptic guarantees effective protection of wood from rotting, fungus, lichens, and various insects for up to 45 years.

Fire retardants - fire retardant solutions

Due to the fact that wood is a highly flammable material, it requires special fire-retardant treatment, which will increase the resistance of lumber to fire. Formulations for these purposes are called fire retardants, and they are produced in liquid, paste and powder forms.

• Impregnations are aqueous solutions designed for deep penetration into the wood structure.
• Varnishes form a protective transparent and thin film on the surface, which will protect the wood from rapid heating and fire.
• Paints and enamels perform two functions at once - protective and decorative.
• Coatings are paste-like compositions that are not decorative; they are intended only to protect surfaces from open fire.
• Powdered fire retardants are applied to surfaces using special equipment using the spraying method.

Fire retardants are also divided into compositions for surface treatment and deep penetration into the wood structure, as well as solutions for external and internal use. For processing facades they are used weatherproof compositions, and for the interior - environmentally friendly solutions that are resistant to aggressive environments, especially if wooden surfaces in baths or bathrooms are impregnated.

Another important distinctive feature fire retardants is their principle of action, which can be active or passive.

• Active substances are substances that, when heated, can release non-flammable gases that prevent oxygen from reaching the source of combustion. This reduces the possibility of flame spreading.
• Passive fire retardants are solutions that, when the surface of wood is heated, form a layer that protects the structure of the wood when exposed to fire. The compositions have the property of melting at high temperatures, creating a non-flammable “crust”, which, by the way, wastes a lot of thermal energy, which increases the overall heat resistance of the wooden structure.

Fire retardants are included in their product range and are manufactured by the same companies that produce other wood protection products.

• The compositions “Senezh Ognebio” and “Ognebio Prof” are intended to increase the resistance of wood to open fire and protection from biological damage. These preparations are used to treat external walls before painting them. If the protective layers formed by such flame retardants are left uncoated, the substances will quickly erode.

• "Neomid 450" and "Neomid 450-1" are highly effective solutions for protecting wood from biological damage and fire. They are used for application to external and internal surfaces that have undergone machining, but unpainted and not impregnated film-forming compositions. If fungal infections are found on the surfaces, they should be treated with bleaching agents before applying the fire retardant.

• "Pirilax" is a bio- and fire-retardant solution intended for impregnation of wood and materials made on its basis, which can be used for external and internal work. The composition perfectly protects the tree from wood-staining and mold fungi, wood-boring beetles. And besides this, it increases its resistance to open fire. In general, thanks to this treatment, the service life of any wooden parts is extended, the risk of cracking is reduced, and deterioration is slowed down.

The composition is compatible with other paint and varnish solutions, so it can be used for painting. The manufacturer of the Pirilax product indicates on the packaging that it provides antiseptic protection for wood for up to 20 years, and fire protection for up to 16 years. Moreover, the composition is an environmentally friendly material, safe for people and the environment.

Fire retardants from other domestic and foreign manufacturers can be found on sale. When purchasing any of them, it is recommended to carefully study the characteristics of the solution and the instructions for its use.

Compositions that provide UV protection

Buildings built from wood lose their attractive original appearance over time, as they are constantly exposed to damaging ultraviolet radiation. To protect facades wooden houses or baths, it is necessary to timely treat surfaces with preparations specially designed for this purpose.

Protective agents, which are designed to prevent the harmful effects of sunlight, contain pigments and special additives that reduce the destructive effects of ultraviolet radiation.

A wooden surface treated with a special product will be protected from damage by ultraviolet radiation for 8–10 years, after which the treatment will need to be renewed. If a colorless solution is chosen for the coating, the coating will have to be renewed every 3–4 years.

If blue discoloration or mold damage is found on the lumber, then before coating them with protective compounds it is necessary to treat with strong antiseptics.

The following compositions can be cited as an example of this type of product.

• "Senezh Aquadecor" is a decorative composition that is not only an excellent antiseptic, but also includes special components - UV filters that absorb solar radiation. Thanks to such components. the wood does not darken, maintaining its original appearance. Senezh Aquadecor is produced in a wide range of colors, which allows you to choose the most suitable shade for coating external or internal surfaces.

• « Biofa 2108" - This is a special solution made in Germany. This product contains microparticles of white pigment, which protect the wood from UV rays. The product can be used to coat interior and exterior wooden surfaces. When applying the solution to wood, the natural color of the material does not change.

The composition is made on the basis of linseed oil, which is well absorbed into wood without creating a film on the surface. Due to the fact that the product is oil-based, it is not compatible with aqueous solutions. "Biofa 2108" - This is an environmentally friendly product, so the coating made from it is breathable and does not emit toxic fumes into the environment.

Protective solutions for wood exposed to damp conditions

Parts of wooden buildings in contact with the ground, buildings located in regions with traditionally high humidity, as well as internal wooden surfaces of baths and saunas require the use of products specially designed for their treatment.

The oil is quickly absorbed into the wood structure, emphasizing the beauty of its texture. In addition to oil, the product contains a special wax, which is a water-repellent component.

The wax does not peel off from the surface, increases the wear resistance of the wood, makes it hydrophobic, and also prevents the occurrence of mechanical damage. The manufacturer has provided the possibility of tinting the product, the color range of which includes 39 shades.

To protect surfaces in baths and saunas, there are also special compounds, designed to withstand high temperatures, steam and moisture. Therefore, if it is necessary to treat surfaces in these buildings or separate rooms, you should choose products whose packaging indicates their specifications:

• “KRASULA® for baths and saunas” is a decorative and protective solution containing natural wax, used for treating both dry and wet surfaces. The functions of this tool are as follows:

— protection of wood from penetration of moisture, dirt, soot, grease, soap solution, as well as from the formation of stains from adhering leaves;

— destruction of existing damage to the tree by mold, algae and prevention of relapses;

— protection from damage by harmful insects, such as wood-boring beetles;

The product has been tested for safety operation during high temperatures. It does not change the natural appearance of the wood and preserves its natural aroma. It is important that the composition does not clog the pores of the material, allowing it to “breathe”.

It is especially important for bath conditions that this is an environmentally friendly solution, safe for the environment and people. It is convenient that it is possible to carry out processing in a humid environment without waiting for the surfaces to dry.

The manufacturer provides a guarantee for wood protection for a period of 7 years in relaxation rooms of baths and saunas, as well as 5 years for the surfaces of washing and steam rooms.

• “PROSEPT SAUNA” is a composition that is a composition of synthetic biocides, made on a water basis. It is used to protect the internal wooden surfaces of baths and saunas from wood staining and wood-destroying manifestations. Prevents the formation of fungal colonies and pathogenic microorganisms on healthy wood. The solution provides reliable protection against moisture penetration into the wood structure at high temperatures.

"PROSEPT SAUNA" can be used not only to protect new surfaces, but also to stop existing destructive processes. The active components of the antiseptic quickly penetrate the wood structure, binding to its fibers. This creates a special resistance of the material to moisture penetration and leaching of the product itself.

This product is used as a base for treating surfaces with oils intended for bath rooms, for painting or tinting.

• "Senezh Sauna" is another solution designed for treating wooden surfaces in rooms where high humidity and high temperatures. The impregnation has an environmentally friendly composition that does not release toxic substances into the environment.

Protective agents for unbarked wood and wood with high natural humidity

If fresh wood is purchased for construction, not dried, or a log that has not been cleared of bark, then before laying the material to dry, it is necessary to carry out the process of processing it. For this purpose, it is recommended to use specially designed products that will reliably protect the wood while it is drying under natural conditions.

The preparations used to impregnate such wood have the property of deep penetration into the structure of the material, allowing it to “breathe” and create unacceptable conditions for the appearance of fungal formations and insect damage. Such solutions include “Neomid 420” and “Neomid 46”, “Senezh Insa” and “Senezh Trans”, “Prosept-42” and “Prosept-46”, “Eurotrans”, “BS-13” and others.

Protection for the ends of beams and logs

A specific area of ​​lumber that requires enhanced protection is the end portion of a beam, board or log. Due to the fact that the end has a more porous structural structure, through it moisture is intensively absorbed into the wood, penetrating deep into the products. As a result, in the created favorable microclimate, mold that destroys the material easily forms. In addition, waterlogging in these places leads to the appearance of deep cracks, which sharply reduce the quality of the purchased material, becoming vulnerable points for further damage to the wood. Therefore, for processing of this area of ​​wood products has been Special antiseptic agents have been developed that are applied to the material being prepared for construction or cladding, or to the ends of the logs or beams of a finished house or bathhouse structure.

The most popular means for protecting the ends of lumber is “Senezh Tor”, which has all the necessary qualities. Moreover, the processing process must be carried out not only for new materials, but also for already commissioned facilities, at intervals of every three to four years.

Preservatives for old painted wood

It is more difficult to save painted wood from biological damage, since getting rid of the old paint and varnish coating is not at all easy. Moreover, even in cases where the coating has cracked and began to peel off.

In order for the protective agent to show its effectiveness, all layers of paint will have to be removed from the wood. This process can be carried out in several ways - mechanically, using a spatula or a grinder with a nozzle in the form of a metal brush, and chemical method, when special compounds are applied to the surface, softening and peeling off old layers of decorative finishing.

Antiseptics can be applied only after the surface has been completely cleaned of paint layers.

Protective measures are carried out both before subsequent painting of wooden surfaces and when leaving the cleaned material in its natural form.

To treat cleaned surfaces, antiseptics such as “Valtti Techno” and “Homeenpoisto 1” are used, which are able to penetrate deeply into the structure of previously painted wood and protect it from emerging problems. If the surface is clean old paint completely, if desired or necessary, it can be bleached to a natural color, while simultaneously performing the necessary “treatment.” The name and description of the whitening compositions were presented above.

What to look for when choosing a wood preservative?

Regardless of the purpose for which an antiseptic is chosen, it is very important when choosing it to pay attention to some points that will determine the quality of the composition and the duration of its protective effect.

• Manufacturer. It is necessary to correctly understand that protective compounds that meet all established criteria can only be manufactured using high-tech specialized equipment, which is available exclusively from large specialized companies.

As a rule, such enterprises have been operating for decades and have already gained a certain authority among consumers. Therefore, in order not to purchase a low-quality product that will not work properly, it is best to buy a solution famous brand. Of course, you won’t be able to save money on such products, but you can be sure that the protective qualities of the purchased solution will correspond to the description given by the manufacturer on the packaging.

• Validity effective protection. As established experimentally, antiseptic protective coatings are able to act effectively for no more than two to seven years, depending on their quality. That is, in any case, they will need to be updated over time.

If the manufacturer specifies a service life of 20–40 years, then such a characteristic should hardly be trusted unconditionally. Any, without exception, even the highest quality protective agent, under the influence of external factors, gradually loses its original properties. The characteristics presented above indicate the service life given by the manufacturer. However, when purchasing one or another version of an antiseptic, you need to carefully study the packaging and find out the conditions under which such a period is possible.

• Consumption of protective composition. Many consumers immediately pay attention to the cost of the antiseptic and try to save money by purchasing a more affordable solution. However, it is necessary to look at the material consumption indicated by the manufacturer, since many of them, having a low cost, require high consumption and application in two or even three layers. To be able to navigate this parameter, you need to know that the average varies from 200 to 250 g/m². Only fire retardants can have a high consumption - here it can be 400÷600 g/m².

If large-scale work is planned, then it would probably be useful to immediately calculate how much antiseptic solution will be needed for the treatment. Calculating the flow rate for any area (for example) usually does not cause problems. It is more difficult when you need to process lumber, timber or boards - many people begin to get confused on these issues.

To make this calculation as easy as possible, there is a calculator below that will carry out the necessary calculations in just a few seconds.

Calculator for calculating the amount of antiseptic composition for processing lumber

The program will calculate the consumption of antiseptic for processing in one layer, taking into account the traditional reserve of 10 percent. It is important that the amount of the finished solution is calculated, since many formulations are sold in the form of concentrates, which must be diluted before use in accordance with the manufacturer’s instructions.

To simplify the task, the quantity of lumber can be indicated either by piece or by volume, that is, in “cubes,” as they are often purchased at bases.

Consumption is indicated by manufacturers either in milliliters per m² or in grams - alas, but there is no unity on this issue. It's okay - the principle of calculation does not change in any way.

– valuable, natural construction material. Buildings made from it have a good microclimate, optimal level humidity, they are warm and comfortable in winter, and quite cool in summer.

But the material is organic, and therefore various biological factors pose a danger to it: insect pests, bacteria, and much more. Therefore, the tree needs reliable protection.

Combined

Which antiseptic do you prefer? How to make a choice?

In order to choose the composition that is optimally suitable for quality, it is necessary to take into account several important factors. This is the density and porosity of the material, its ability to absorb, the type or type of wood.

Based on their resistance, tree species are usually divided into the following groups:

• Persistent. They are characterized by resistance to rotting processes, reliability, strength and durability. These include oak, pine, larch core and ash.
• Medium resistant. They have lower resistance to decay processes. These include sapwood, spruce, cedar and fir.
• Low resistance. They are not as durable and reliable as the two types already noted. These include the sapwood of oak, maple, beech, birch, and elm core.
• Unstable. These are the types of wood that are more susceptible to negative putrefactive changes than others. These include alder, birch kernel, linden sapwood, and aspen.

1. Easy to impregnate - these types include birch sapwood, beech and pine.
2. With moderate ability - these include aspen, pine heartwood, oak, maple and linden sapwood.
3. Difficult to impregnate - spruce, ash, oak and birch cores.

Use of antiseptics: classification by purpose

Banding and antiseptic treatment

All drugs can be divided into two conventional types, depending on their main purpose:

• Preventive. They are used at the very beginning of construction or even before the start of the process. It is quite acceptable to begin processing with such material immediately after the necessary lumber has been purchased. It will be possible to begin priming and painting only when one or two layers of the preparation are completely absorbed into the surface of the wood.
• Medicinal. They are resorted to in cases where problems with the material have already appeared and need to be eliminated. For example, wood has undergone putrefactive processes, or has been damaged by microorganisms and insects - these are the types of products that can help it. Therapeutic antiseptics can also be used as prophylactics, in cases where it is known in advance that the operating conditions of the potential structure will be unfavorable. For example, this will be high humidity.

Antiseptic solutions: classification by use

The most suitable antiseptic composition is selected depending on the type of wood and the purpose of the material. The features of processing wooden products also depend on this. According to the method and area of ​​application, all antiseptics can be divided into two types.

For outdoor use

External preparations are substances that are used to protect wooden parts exposed to harsh outdoor conditions.

Since these objects are actually under open air, then they quite often experience the influence of the environment: ultraviolet radiation, precipitation, sudden changes in temperature, etc.

Therefore, used in in this case external antiseptics must be durable and of high quality, providing reliable protection.

They often have a sharp, specific odor, which can only be gotten rid of after the treated material has completely dried. This may take from one month to two.

These substances tolerate solar radiation well, the negative effects high humidity, but they are not intended for interior work.

They, in turn, are divided into two groups:

• impregnations - these compositions are intended for deep penetration into tissues to destroy insects and fungi in them;
• finishing coatings – designed to protect the impregnating layer from weathering. They do not penetrate deep into the fibers, but they form a special protective film on the surface of the processed material.

Both finishing preparations and impregnation antiseptics can be used separately, but often owners choose combined products that have different functions.

For interior work

These compositions are characterized by one feature: after processing, a microfilm is formed on the surface of the material. It seems to clog toxic substances, not allowing them to erode. This is very important for substances used for, since it ensures not only the safety of the wood, but also safety for the health of people in the room. These products are quite stable and do not require regular subsequent application.

The specific type of drug is selected depending on the purpose of the room being treated. If you choose an antiseptic for treating surfaces in a room where high temperatures and extremely high humidity are expected, products for saunas and baths are suitable. It is necessary to study the performance characteristics of the drug indicated in its passport. It is better to buy drugs from reputable companies to avoid unpleasant surprises.

Wood as a building material has a large number of advantages, among which it is worth highlighting manufacturability, insulating abilities (heat and sound), ease of processing, environmental friendliness, unique natural beauty... However, being a natural material of organic origin, lumber and house elements assembled from them , their entire service life remains dependent on a number of climatic and operating conditions. Wood must be looked after and protected. How to do this and with what – we will look at this article.

Key principles of wood protection

Practice shows that only then can effective protection be achieved wooden house, if we take the concept as a basis STAGED And COMPLEX processing using COMPATIBLE compositions among themselves .

The essence of the problem

The enemies of lumber and wooden structures in general are:

• Water. A board or timber can change its moisture percentage even when the air humidity changes. Due to sudden changes in humidity, the workpiece: swells/shrinks, cracks, warps (curves), rots, darkens... It is water that, under certain conditions, causes the development of fungi, since it is a nutrient medium.
• Pests. This should include: fungi (coloring, destructive, mold), algae, wood-boring insects. The vast majority of these infections not only worsen the appearance of the tree and reduce the grade of lumber, but also cause a loss of strength characteristics of structural elements, which can lead to deformation and destruction various elements Houses.
• Fire. Wood supports combustion (carbon monoxide, high temperature...), and something must be done about this, because fire is the most destructive danger.
• Ultraviolet. Tree, for a long time If exposed to the sun, it darkens, ages, and is systematically destroyed from the outside.

A complex approach

Builders solve the problem of protecting the wooden elements of the house in a variety of ways, ranging from careful selection of raw materials and compliance necessary requirements to the procurement process, ending with the correct storage and transportation of lumber, selection of the most suitable location for building a house, development of optimal structural and architectural configurations.

But this turns out to be not enough, for example, it is not enough to simply exclude direct moisture of the wood or comply with all the provisions of the PUE. To guarantee a home that is comfortable, durable and safe, you need modern chemical protection. Old "grandfather" methods cannot give the results required by strict building codes our time.

The entire protection system is based on three pillars:

• Antiseptics (pest control);
• Fire retardants (fighting ignition and fire spread);
• Decorating paintwork materials.

In addition to aesthetic purposes, decorating compositions can do something else: create a layer that prevents moisture from penetrating into the fibers, prevent the wood from getting dirty and darkening, fading under the influence of ultraviolet radiation, wearing out under load, etc. Some formulations destroy microbiological contamination.

Obviously, the third point is not mandatory if we are dealing with structures that will be hidden from view. But antiseptics and fire retardants always go hand in hand, which is why the general inseparable concept “FIRE BIOPROTECTION” appeared, and means of combined action appeared. Many years of experience show that when used correctly modern means Wood processing allows you to obtain the desired result relatively quickly, quickly and safely for humans.

It is worth highlighting the main consumer requirements for fire-retardant compounds:

• Effective action
• Maximum working life,
• Environmental friendliness,
• Absence negative influence on the appearance of the wood,
• Versatility and ease of use,
• Good compatibility with other compounds,
• Affordable price of fire protection.

What exactly is subject to fire-bioprotective treatment in a wooden house?

Ideally, it is desirable to process ALL wooden elements of the house: walls, floor beams, partition frames, joists, rafters, roof sheathing, wall/free-standing frame beams, windows and doors, all types of cladding inside and outside the building.

Let's not forget that mineral materials (concrete, brick, a natural stone, plaster...) under certain conditions can also be affected by harmful microorganisms, for example, mold. In the construction of wooden houses, experts recommend that they also be subjected to antiseptic treatment, so as not to unexpectedly get a source of wood infection right inside the house. Of course, special attention is paid to “risk areas” that are subject to mandatory treatment.

That is, elements that are operated in conditions of high humidity, because it is prerequisite vital activity of dangerous microorganisms-pests. This - lower crowns“log buildings” (timber or logs), frame and façade cladding, walls of steam rooms, joists and floor lining on the ground, open street structures, etc. Here, to combat biodestruction, the most powerful antiseptics are used, in increased concentrations, with a large number of layers.

And, for example, in terms of fire safety measures, the most demanding will be roof structures or premises of a wooden house with various types heat generators (boiler rooms, halls with fireplaces...).

When can you use fire retardants and antiseptics?

If we talk about the time of year, then everything is limited only by the manufacturer’s recommendations for operating temperatures protective compounds. In extreme heat and winter it is usually impossible to carry out treatment, although, for example, fire bioprotection Pirilax Lux can be applied in frosts of -15 degrees. But from the beginning of spring until late autumn, it’s time to defend yourself. Moreover, already in early spring all pests begin to be active, and it is easiest for them to get into lumber.

Preparatory stage. During the period of harvesting and transporting lumber, as well as during storage of lumber on site, it is necessary to avoid damage to the workpieces and parts by mold and other types of fungi, since a fairly decent period of time may pass before the wooden products are used and the house is covered under the roof. For these purposes, so-called “transport” antiseptics are used, the effectiveness of which, meanwhile, is best achieved by observing basic rules storage and transportation of lumber and finished products made from it.

Note that auxiliary parts and fixtures also need to be processed. For example, disinfect spacers for stacks of lumber, or open them with fire retardants scaffolding which are made of wood (according to statistics, it is quite common for a fire to spread to a building via wooden scaffolding and scaffolding).

Initial stages of construction. Here we are usually talking about “responsible” structures, which, as a rule, perform certain load-bearing functions. This category specifically includes structures and elements from the “risk zones” that we discussed above (lower crowns, beams, columns, joists, rafters, posts and lintels of frames, battens and counter-battens...). They form the basis of a wooden house; after construction is completed, they often become closed and inaccessible for reprocessing, and therefore require particularly careful protection, which will last for many years in a row.

The fire-retardant and antiseptic compounds that are needed for such units must penetrate deeply and be securely fixed in the wood, remain there under all conditions, and provide maximum bactericidal/fire-fighting effect.

Finishing stages. When the construction of a wooden house comes to completion, the decorative finishing surfaces. Inside and outside the building, wooden elements are exposed with protective and decorative compounds (glazing or covering), which can also serve as an antiseptic.

It is important to take into account that at any stage, fire-bioprotection should be applied in a timely manner, or rather “the sooner, the better”, because it is much easier to deal with problems preventively than to later fight the consequences of pest activity or assess damage from exposure to precipitation or fire. If the moment when it was necessary to engage in prevention has been missed, and the first signs of lumber infection by pests have appeared (dark spots, blue spots, insect passages, traces of mycelium...) - then you need to immediately begin eliminating the pathogen so that the building material does not have to be used only as firewood . And here you will have to apply the most powerful tools, capable of coping with already rampant pests. Fortunately, compositions intended also for treatment exist, for example, the well-known “Nortex-Doctor” from the company North.

How to choose a wood preservative, selection criteria

There are relatively universal materials for wood processing, which combine several functions at once. But many of them have a rather narrow specialization, are designed for use in specific conditions, and are distinguished by special properties. Therefore, before starting your search, it is recommended to decide on a certain amount of input data in order to buy the most effective fire protection for your conditions. There really aren't many of them:

• What are the specifics of the object? There is a big difference - this is a bathhouse, outbuilding, residential building, fence or, for example, street furniture.
• What material will the surfaces be processed from? wooden house- structures made of wood, stone elements or, for example, textile products.
• What type of elements are subject to processing - crowns, wall frames, roof subsystem, floor, ceiling, clapboard cladding, decorative details, scaffolding, etc.
• Is it necessary to treat already infected wood, or will preventive protection of lumber and structures be carried out?
• What kind of material will be used for finishing- compatibility of fire-bioprotection with decorative paints and varnishes is required.

Types and features of various protective equipment

So, we have already decided that there are three main types of compositions that work best when used in combination. However, within each of these categories there are many significantly different options, especially when considering products different companies. Let's try to understand the principle of operation and areas of application of various models/lines using the example of products famous company NORTH.

Antiseptics

Protection of wood from biological damage is carried out with compositions based on oils, volatile organic substances, or water-soluble agents. Not all of them are equally effective and practical, some of them stop working too quickly, others heavily stain the lumber, hiding the beautiful texture of the wood. There are antiseptics that create an impenetrable film on surfaces, which prevents the wood from “breathing” and traps capillary water inside. Many of these “helpers” are very harmful to health and therefore have many restrictions on their use.

Recently, there has been a clear trend towards increasing popularity of aqueous solutions (antiseptics and fire retardants). A striking example Bioprotection can be provided by modern environmentally friendly antiseptics from NORT: Nortex®-Lux, Nortex®-Doctor.
Data liquid formulations They have a comprehensive effect on pests, as they contain active insecticidal and fungicidal components in their composition, which reliably kill fungi, algae, beetles and mold. They also prevent the reappearance of pests (30 years for “Lux” and 10 years for “Doctor”). These are impregnations that penetrate deep into lumber and, binding to wood molecules, work there for a very long time, while they do not form films and do not stain the wood. They can be applied at any stage of construction, both when creating blanks and for processing finished structures.

It is noteworthy that Nortex-Lux and Nortex-Doctor, due to their safety for people and animals, can be safely used indoors, and the first can even be used inside a sauna or bathhouse. The main feature of the Doctor antiseptic is the possibility of not just prevention, but also treatment of already affected structures. Both compositions also prevent the wood from aging and deteriorating.

The company has two more interesting models antiseptics - “Nortex-Transit” and “Nortex-Bleach”.
As the name suggests, Transit is intended for temporary protection (from 3 months to one and a half years, depending on the proportion of dilution of the concentrate and the number of layers) of lumber during storage and transportation, as well as for the protection of log houses that are being aged. It can even be applied to freshly sawn boards and beams of natural moisture; when the composition is heated, it can be used for processing in sub-zero temperatures.
Bleach allows you to lighten wood that has darkened for some reason. In addition to restoring the appearance, this two-component aqueous solution allows you to cope with wood-staining fungi. This suggests that the composition does not simply mask the defeat, but fights it and protects against problems in the future.

Fire retardants

Fire retardants should be considered compositions that provide the 1st or 2nd group in terms of the effectiveness of fire protection of lumber according to GOST 16363-98 Fire protection products for wood. Methods for determining fire retardant properties (or according to GOST 53292 - 2009). The first group is characterized by more stringent requirements and is recommended for processing critical load-bearing structures.

It makes sense to divide modern means for imparting fire-fighting properties to wood into two types:

• Coatings,
• Impregnations.

Coatings include all kinds of varnishes/paints, coating pastes and other chemicals, which leave a relatively fire-impervious layer on the surface. But they change a lot appearance wooden products or even completely hide the color and texture of the wood. It is clear that such products cannot be used to protect visible structures, especially since many of them emit harmful substances and are unsafe for people.

Of course, fire retardant impregnations are more advanced and multifunctional. For example, the NORT company presents an innovative, but already trusted in practice, family of biopyrenes “Pirilax”, as well as the composition Ozone-007 and dry concentrate Mig-09.

The operation of these fire-bioprotective agents is based on the formation (in fire conditions) of a foam coke coat on the surface of the lumber, which, in the event of a fire, prevents oxygen from penetrating into the fire zone and protects the wood from high temperatures due to the reduced thermal conductivity of the porous mass. In parallel with the endothermic reaction, the resulting layer releases non-flammable gases. As a result, the burning of the wood stops.

Interestingly, the active formula of NORT biopyrenes consists of substances that are part of the tree initially, so they are not rejected and form in the fibers a so-called “wood polymer” that is non-flammable and uninteresting for pests.

Pirilax-Lux and Pirilax-Classic are a ready-made combined product that will prevent fire for 16 years and prevent damage to wood by insects, algae or fungi for up to 25 years. That is, having performed such fire protection of wood or materials created on its basis (plywood, OSB, glued parts...), it is no longer necessary to additionally treat the structures with an antiseptic.
The product can provide the second or first group of fire-retardant effectiveness (depending on the number of layers applied), preventing wooden structures from catching fire or spreading flames. It can be used outside and inside the building, and processing can be carried out at temperatures from -30 degrees.

The entry-level fire protection NORT Pirilax-Prime kills mold, protects wood from rotting, and destroys wood-boring beetles. The composition's shelf life as an antiseptic is about seven years. “Prime” protects against fire for 5 years, so it is best used in open structures, which can be reprocessed. Moreover, it does not stain wood, does not create a film, and combines perfectly with various paintwork materials. Pirilax-Prime showed itself very well in combination with the compositions of the Krasula family.

Separately, it is necessary to highlight the “Pirilax®”-Terma model from NORT. This protective complex was specially created for processing wood in steam rooms, where very high temperatures are observed during heating and people are present. Although it can be used in any other conditions, outdoors or inside a building. In a sauna or bath at 110 degrees or more, the composition does not emit substances harmful to humans, while it has a combined effect: antiseptic and fire retardant. Pirilax-Terma slightly colors the wood with light amber notes and can be easily combined with the vast majority of decorative compositions that are used in steam rooms.

Biopyren "Ozone-007" is a relatively inexpensive impregnating composition that is designed for interior work. Its main purpose is fire protection, which has been working for 30 years. However, an antiseptic effect is also provided.

Biopyren "Ozone-007" is a relatively inexpensive impregnating composition that is designed for interior work. Its main purpose is fire protection, which works for 30 years. However, an antiseptic effect is also provided.

Ozone-007 is available in the form of a concentrated paste or a ready-made solution. In any case, it is colorless, so if you want to control the quality of the application, then it can be tinted with a bright color (for example, red E129 - then possible gaps will become clearly visible).

Most often, parts are treated with this composition roofing system And wooden floors. Ozone-007 can be used at temperatures from -5 degrees and applied to wood with humidity up to 25 percent or more.

Biopyren Mig-09, which is usually used for treating rafters and attic floors, shows similar characteristics. The fire protection it provides is 12 years. The composition of Mig is a dry concentrated powder, it is safe for people, suitable for all types of buildings, including those operated in damp areas.

Note that in addition to fire-bioprotection from the NORT company, it is best to buy protective and decorative compositions from the same manufacturer, for example, compositions from the Krasula series. This way the layers will be guaranteed to fit well with each other. By the way, many Northovsky finishing paints and varnishes themselves have a bactericidal effect, for example, “Nortovo interior varnish”, “Nortovskaya interior primer”, “Krasula for baths and saunas”, “Krasula for ends”...

Some rules for using fire protection

• 1. No matter how trivial it may sound, always study the manufacturer’s recommendations and strictly follow them.
• 2. Select the type of composition, the method of its use, depending on the characteristics of the surfaces (humidity, rock, roughness...) and the nature of the tasks (for example, prevention or treatment is needed).
• 3. Always take care of safety, both during application and when choosing materials.
• 4. Take the time to clean. Do not try to work on dirty surfaces, or if they, for example, have some kind of film, dust, or sawdust.
• 5. Try to work on a dry surface, preferably in dry weather.
• 6. Always comply temperature regime application.
• 7. Choose the application method that provides less consumption. A full range of methods are usually available (roller, spray, brush, dipping).
• 8. Process structures and lumber without skipping.
• 9. For maximum protection, carefully and step-by-step combine only compatible compounds different actions(fire retardant + bioprotection + decorative means) to ultimately obtain a comprehensive, durable complex.
• 10. Do not buy protective materials in advance; everything has its own expiration date, even in sealed packaging.
• 11. Don’t forget that there is no permanent protection, so periodically renew the impregnation within the time limits specified by the manufacturer.
• 12. Choose only a trusted supplier of lumber and fire protection who cares about its reputation.
