Impregnate the wooden materials that you. Which antiseptic for wood is better to choose: calculation and methods of treating wood with an antiseptic. How to choose the best wood impregnation: consider the purpose of the purchase

Tree- This is one of the oldest and most stylish building materials besides stone and clay. Throughout the history of construction, man has gained vast experience in handling wood, learned its features, and learned to make it stronger and more durable with the help of protective equipment. The main one of these points is the use of impregnation for wood and its elements.

Wood is a very durable and unique building material that has a huge amount of positive qualities and properties that will be valued at all times. In houses that are built of wood, it is always necessary to maintain natural and more comfortable warmth, and there should always be enough oxygen in the air. The use of special types of wood in construction will allow you to create a special healing atmosphere throughout the house due to microscopic volatile substances and resins, which will have a huge impact on your health.


Despite the masses of positive advantages, wood also has its disadvantages and drawbacks. If you do not take precautions, the wood can deteriorate from the presence of moisture, various types of fire, various insects or rodents. And if in ancient times people used various suitable means for protection, today it will be enough just to treat the entire tree with a special impregnation.

Buy suitable composition for impregnation of wood, you can find it in any construction hypermarket or market. This is a specific composition that is designed to protect the structure of your tree from destructive and negative influence all environment, any biological factors and fire. The composition of the impregnation, depending on its components and purpose, can be divided into several types. For example, some impregnations are oil-based or water-based and organic-based.

According to their purpose, impregnation is usually divided into the following groups:

  • Fire retardants. The main purpose of this group of impregnations is to protect wood from fire or other combustion processes. Such impregnations contain certain components, the melting of which begins with increasing temperature, thereby creating a durable film on the surface of the wood. Its essence is to block the access of oxygen to the tree, and without oxygen, as we all know, there will be no fire. Fire-prevention impregnation for wood must be used during the construction and repair of log houses, as the main guarantee of subsequent safety;
  • . Antiseptic impregnations protect wood from decomposition and rotting, as well as other types of biological damage. This impregnation contains biocides (special potent poisons), they effectively destroy any pathogenic microorganisms and small insects, preventing them from multiplying and multiplying and at the same time destroying the wood from the inside.

The most common antiseptic impregnations: Aquatex, Kram, Biosept, Tikkurila, Vintol, Biotonex, Senezh;

  • Anti-atmospheric. Such impregnations serve to protect wood from various negative environmental influences and atmospheric precipitation. All compositions of this impregnation protect the structure of the wood from the formation of various cracks, drying out and other deformations. One of the significant disadvantages of such impregnations is that after their treatment, the wood loses its external aesthetic appearance and deteriorates its certain characteristics. Protecting the tree from moisture and water, the best option will be complete impregnation – i.e. immersion in the bath.


  • Water-repellent special impregnation for wood is a solution that increases the strength of the entire material and its high resistance to water; wax is more often used. These compositions significantly extend the life of wood buildings. This impregnation for wood against moisture and rot is ideal for you. More common and popular in the Russian construction market are solutions such as Tikkurila.

Quite often included water-repellent impregnations wood contains oxides of certain metals, which protect the material from the destructive effects of ultraviolet radiation, as well as fading and drying out. But the oxides will also give the impregnation a certain color. Depending on the metal used, the color varies from light yellow to burgundy, or blue and violet. Therefore, you can not only protect the wood, but also make it original and beautiful. appearance;

  • Combined. Combined impregnations are compositions that protect wood from various factors, for example, from fire and various bacteria, from water and the formation of harmful fungi. In places where humidity is high and the risk of wood contamination is very high, such impregnation is very useful.

Impregnation selection criteria


In order to choose a specific protective solution, consider some nuances. For example, if you choose an impregnation produced on water based, then you will need additional drying of the wood, which will lead to its deformation.

Use antiseptic impregnations, which are water-based, to treat the linings under the purlins and the purlins themselves; you can also paint partition panels, joists and beams, beams. In this way, you can process elementary lightweight structures that will not deform or bend, and which will not cause much harm or damage.

Oily compounds and wood impregnation oils have an unpleasant persistent odor, which is quite difficult to weather, and therefore it is better not to use these wood impregnations for internal processing of wooden structures. Besides, everything oil solutions ignite very quickly, releasing toxins into the air. Once you have treated the wood with oil, it will become impossible to work, paint or process. Therefore, oil impregnations are only suitable for wooden parts and elements located outdoors and regularly in contact with water.

You should choose an antiseptic impregnation for wood taking into account the specific type of wood, since different types have varying degrees of resistance to various biological destroyers:

  • “weak” wood is aspen, linden, alder;
  • low-resistant wood - oak, birch and beech sapwood, elm heartwood and maple;
  • medium-resistant wood - fir, spruce, larch, cedar sapwood;
  • rot-resistant wood - ash, pine, oak heartwood and larch.

Different types of wood absorb certain protective compounds differently, and this should be taken into account when making the final choice of impregnation.

Three main groups of wood can be distinguished based on the difficulty of absorbing impregnation:

  1. difficult - spruce, ash, oak and beech;
  2. medium - linden, pine core, alder, aspen, maple sapwood;
  3. light - beech, pine sapwood and birch.

The nuances of do-it-yourself impregnation at home


The price of wood impregnation will depend on its purpose and composition, but you can save a lot and prepare a simple protective impregnation for. In this case, impregnation will be much cheaper than a budget purchase option.

The basis of do-it-yourself impregnation is.

Impregnation preparation process:

  1. Pour bitumen into an unused old metal bucket or container.
  2. Place the bucket on the fire and bring the bitumen to a boil.
  3. Remove the bucket from the heat and, while stirring, pour in diesel fuel in a thin stream so that the mixture does not have time to thicken even after it has cooled.

In order to prepare a quick-drying impregnation, dilute the bitumen not with diesel fuel, but with gasoline. But in in this case do not heat the composition - the bitumen should completely dissolve in gasoline. After treating wood with this solution, it can be safely painted, coated with various enamels and primed. But under no circumstances use nitro varnishes and paints!

That is why during the processing process, remember your safety measures, and strictly follow the instructions from the manufacturer. Before you buy impregnation, carefully study the information about the degree of toxicity of the composition and its possible use and application inside the house.

Impregnation for wood is a necessary and important protective measure in modern repairs and construction.. Regardless of the hazardous chemicals contained in the impregnation, it can significantly increase the service life of all buildings and ensure safety from fires and various atmospheric phenomena. Good luck!

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 microflora and for many insects. To avoid rapid damage to the material and to maximize the durability of 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 on various bases - it’s not so easy to figure it out “at a glance”. 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:


- Water-based antiseptics used for protective impregnation of 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 for impregnation 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 that are fixed to 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 works . This category includes antiseptics for preparatory and decorative work, which are highly resistant to aggressive environmental influences, 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 strong unpleasant odor, they are not recommended for use in processing internal surfaces.

- Antiseptics for interior work . 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 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 clean water and dries. 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.


    High-quality and reliable antiseptic “MOKKE” is offered by the Russian manufacturer LKM-color. The product is intended for treating 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 intended 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 decorative composition, which 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 wooden buildings 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 individual rooms, it is worth choosing 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 defeat 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 a log or beam already finished building home or bathhouse.


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.

  • Duration of effective protection. As has been experimentally established, antiseptic protective coatings can 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.

Protection of wood from damage and rotting -required condition its normal use as a building material. There are different methods of protection, but the most effective and popular method turned out to be the use of special impregnations for wood. In this article we will tell you everything you need to know about this group of drugs: from the classification and description of their action, to advice on choosing a specific product for a given situation.

Let us note that there are a variety of impregnations for wood, and a variety of substances that are used in one way or another or are theoretically suitable for use can also be classified in this group. Humanity has known wood as a building material since the beginning of time, so a huge amount of experience has been accumulated.

Attention! We do not review all antiseptics and do not pretend to have an exhaustive catalog of them; we review the most relevant drugs available on the market today.

Main groups

As was said, there are a lot of impregnations, so we will divide them into groups to make it easier to navigate through all this diversity. As a unifying criterion we will choose one or another distinctive feature products belonging to the same group, be it composition, scope of application, main properties or something else.


  • decorative, protective and mixed;
  • natural, synthetic and mixed;
  • moisture-resistant and water-repellent;
  • water-based and organic solvent-based;
  • oil and wax;
  • imparting fire retardant properties;
  • antiseptics against rot and mold;
  • fire-retardant compounds;
  • tinting and colorless;
  • for external and internal work;
  • salt-based and organic compounds.

If you need to protect a wooden product from moisture, you need to answer a number of questions:

  1. Where will the product be used, indoors or outdoors?
  2. How will the part be used, for what purposes?
  3. Who and what will come into contact with the product, will children or food be included in this list?
  4. What humidity regime is expected? Will there be direct contact with water?
  5. What should the part look like in its final form?

After answering these questions, you will have an idea of ​​the requirements that the drug must meet. Next, it remains to choose the right one.

Antiseptic impregnations

Antiseptic impregnations constitute, perhaps, the widest and most popular group of products in this class. This is due to the fact that it is antiseptic treatment that allows you to get rid of the most harmful pests - bacteria and molds, wood-eating insects and other biological agents that cause corrosion of the material.

Experts know that moisture, as such, is not particularly harmful to wood. The problem is that it creates an environment for the development of various microorganisms, such as mold and bacteria. But they are already beginning to cause serious harm: causing rot, turning them blue or gray, consuming cellulose as food, turning the product into dust.

Antiseptics are:

  • transport, such as;
  • for baths and saunas, for example;
  • gels with high penetrating effect;
  • For interior and exterior use;
  • difficult to wash out and unwashable;
  • tinting and colorless;
  • insect repellent;
  • to protect ends like .

Action antiseptic impregnations based on the content of biocidal and fungicidal components in the composition.

Transport or temporary antiseptics are designed to protect lumber during storage, delivery and construction. They are inexpensive and are quickly washed away by rain, so they serve only as a temporary measure.

Solutions may contain color pigments that will help color the product in desired color and highlight its natural pattern. Good for light tinting.

If this is not necessary, you can choose a composition without color pigments. A prominent representative of such a product is a colorless, hard-to-wash antiseptic.


Preparations for internal work must meet a lot of safety requirements, especially when in contact with skin or used in children's rooms. Usually they try to use natural ingredients or their analogues.

Important! The main task of the worker is to ensure the necessary consumption of the product during application in order to achieve a certain concentration and penetration to the required depth.

Fire protection

This group of impregnations appeared not as long ago as many others. Here, as the name suggests, two types of wood protection are combined - from fire and from biological corrosion. In other words, this product is an antiseptic with the addition of substances that prevent combustion.


To better understand the features of such drugs, let's consider drugs and. Both products are a mixture of biocides and fire retardants; these are professional preparations that provide the highest fire safety group and high-intensity antiseptic protection. Suitable for use indoors and outdoors in areas of increased fire danger.

Attention! As a rule, the solution slightly tints the wood into a yellowish or reddish tint, but this is not an impregnation paint; this is necessary to control the quality of the processing. During further finishing, this tint can be easily painted over.

Fire-retardant treatment is the key to your safety. This applies to owners of log houses, wooden houses made of laminated or regular timber, owners on whose property there are barns, chicken coops and pigsties made of wood. This treatment is no less important for the boards of roofing rafter systems.

Decorative and decorative-protective


Most stains are alcohol-based and organic solvent-based. Such preparations penetrate well into the structure of the material, but increase its flammability and combustibility. At the same time, there is a tinting, difficult-to-wash-out antiseptic, which is water-based and therefore odorless, which is characteristic of any alkyd impregnation.

Impregnants are used for deep impregnation of parts that will be subject to operation in wet areas, as well as in outdoors. They can be used to treat furniture.

End Products

What colors of wood impregnations are available on the market?

Wood impregnations, as a rule, are used not only for protection. Beautiful noble wood of a certain species can be very expensive, while with the help of impregnation with oak or walnut pigment, nobility and beauty are achieved at much lower costs.

Pine, impregnated with a well-chosen product, can imitate rowan or mahogany, it all depends on your desire. Light wood easily becomes dark, and black impregnation gives the products a special charm and charm.


A no less interesting effect will be achieved by white or gray impregnation, husky colors and even green. Diversity makes our life brighter and richer, and the use of impregnations with different pigments will help diversify the too moderate shades of wood from which your house, fence, furniture or floor is made.

Important! Wood impregnation is not paint, and it does not have a bright coloring effect and a huge richness of shades within the tinting tables. Impregnation adds tone, emphasizes fibers and highlights the natural beauty of the material.

Top 10 wood impregnations for outdoor use

The most popular area of ​​application for wood impregnations, especially protective impregnations- This is an external treatment.

Currently on the market paint and varnish materials There are quite a few means to protect wood from rot, moisture and other negative influences. But which one and in what cases is it better to use? To answer this question, I suggest you familiarize yourself with the most common types of impregnations and their main features. This information will definitely help you decide for yourself which wood impregnation is best in your case.

A few words about the coverage functions

Before you start choosing impregnation, you need to figure out why it is needed at all? This material can perform various functions:

  • Antiseptic. Protects wood from rotting, as well as other biological influences (fungi, insects, etc.);

  • Water-repellent. The composition clogs the pores of wood, thereby protecting it from moisture;
  • Fire safety. Due to the fire retardant content, fire impregnation makes wood a low-flammable material, i.e. it smolders, but does not burn;

  • Decorative. Serves as a finishing coating that gives the surface of the wood a certain shade and also emphasizes its pattern.

It must be said that modern compositions usually combine several functions, therefore they are divided into two types:

  • Protective. They are applied under paint and varnish coatings, therefore they include only three functions - they protect wood from biological influences, moisture and serve as fire retardants;
  • Protective and decorative. Such compositions are also called 4 in 1, since they perform all the functions described above.

I must say that you may still find exclusively decorative impregnation, which only gives the wood a certain shade and protects it from moisture. Therefore, when purchasing the composition, carefully read the instructions.

Currently, the following types of impregnating compounds are most often used to protect wood:

Option 1: water-dispersed

Water-based impregnations have recently become the most popular due to their relatively low cost and effectiveness. They are both protective and protective-decorative.

Advantages. Water-dispersion coatings have a lot of positive qualities:

  • No smell. Due to the absence of organic solvents, these compositions are harmless to health during the application process, which allows you to work with them without a respirator;
  • Absorbs quickly and dries. As a result, the application process is quite simple and fast;

  • Large assortment of colors. This allows you to accurately select the color of the coating and its shade according to your desire;
  • Versatility. Can be used for both external and internal work. The only thing, keep in mind that not all formulations are universal, so before purchasing, carefully study the scope of application.

Impregnations need not just be applied, as paintwork, and rub into the surface as required by the instructions.

Flaws. One of the disadvantages is the presence of chemicals in the composition, which somewhat reduces the environmental friendliness of the tree.

Price. Below are prices for some water-based impregnations that have worked well:

Conventional impregnations cannot be used to treat baths and saunas, since under the influence of high temperatures they release harmful substances.

Option 2: oil

Since ancient times, people have learned to protect wood from environmental influences with linseed oil and some other natural oils. Due to a number of advantages of this solution, it has not lost its relevance today.

True, modern oil-based impregnations often contain some other components that improve the characteristics of the coating. But at the same time, many manufacturers are trying to maintain the environmental friendliness of the composition.

Advantages:

  • Efficiency. The oil reliably protects wood from moisture and biological influences, for example, linseed oil– it is a good natural antiseptic;
  • Environmental friendliness. Unlike the impregnations described above, the oil does not contain harmful chemicals. Therefore, some compositions based on them can even be used in baths and saunas;

  • Versatility. Can be used for indoor and outdoor use.

Flaws:

  • Need for periodic processing. Wood needs to be treated with oil more often than with chemical impregnation, since it is less resistant;
  • Impossibility of painting. The oil is used exclusively as a finishing coating.

Price:

Option 3: wax based

Waxing is another ancient way of protecting wood from various negative influences. In its protective qualities, wax resembles oil - it also penetrates the structure of the wood and provides water-repellent properties.

It must be said that some manufacturers in the manufacture of such coatings use not natural beeswax, but paraffin. This somewhat reduces the environmental friendliness of the tree, and also reduces its vapor permeability.

In addition, wax does not tolerate high temperatures well, so it can only be used where the wood will not be exposed to thermal effects. But it is more durable than oil, so it has to be applied to the surface of the wood less often.

Price:

Here, in fact, are all the types of compositions for wood processing that I wanted to talk about.

Conclusion

Now you can decide for yourself which impregnation is the best of all those described above. The only thing is, before you go to the store, watch another video in this article. And if you still can’t make a choice, contact me in the comments, and I will be happy to help you.

Wood, along with clay and stone, is the oldest building material. However, despite all its unique mechanical and physical properties, she is very sensitive to influence external environment. Atmospheric precipitation, biological pests, fire are just a small part of the external factors that can slowly, and sometimes very quickly, destroy wooden structures.

The only way to at least partially protect the tree is to treat it with a special appropriate substance that will increase the material’s resistance to negative circumstances.

What's the point of protecting a tree?

Despite mechanical properties wood, under the influence of external factors it loses its properties and is destroyed. Parts of the external part of the house are most susceptible to this, so treatment of such parts is extremely necessary, otherwise the tree will very quickly lose not only its attractive appearance, but also its functionality.

As for fire protection, it has been scientifically proven that treated elements burn much harder, and if the fire is not large, then they will only smolder.


Classification of protective equipment

Means (impregnations) for protecting wood are divided into several groups. Depending on the purpose:

Fire retardants or flame retardants. The main task of the product is to create a film that prevents the entry of oxygen, thus preventing further combustion of the material. Please note that the validity period of fire retardants does not exceed five years; do not forget to re-treat the wood in a timely manner.

Antiseptics. They serve as protection against biological (beetle larvae) and bacteriological (fungal spores, mold) pests. Please note that modern impregnation for wood against rotting is not toxic to people, and does not allow microorganisms and insects to multiply inside structures.

Anti-atmospheric. Their main task is to protect the wooden structure from the influence of the external environment (sun rays, precipitation), preventing the appearance of cracks and all kinds of deformations.

The negative side of such processing is the unpresentable appearance of the material, as well as the loss of a number of physical characteristics.


Moisture-repellent. Moisture impregnation for wood allows you to increase the service life of wood, since it is a hygroscopic substance and, even with high-quality drying, can absorb moisture.

Due to the fact that the composition of such solutions often includes metal oxides, they also affect the finishing shade of the material after processing. The color of wood impregnation varies from pale yellow to purple, burgundy, and blue shades.


Combined. These products combine several types of protection, which is very important in difficult climatic conditions.

Types of protective equipment bases

Depending on the basis, the products are divided into:

Aquatic. The main advantage of such substances is their easy permeability into the upper layers of wood, a minimal drying period (up to 3 hours), the absence of a specific chemical odor, the ability to be used for internal treatment of buildings, they are considered environmentally friendly.

Water-based solutions are divided into salt and salt-free solutions. The main components of salt aqueous solutions are coal, boron, and phosphorus salts. The negative side of salt options includes a short period of protection (up to 5 years), specific application methods, and structures cannot be further finished.

Oil or organic. The functional task of wood impregnation oil is to protect the building material from condensation, while creating a beautiful glossy shine. Often, flax wood impregnation is used for these purposes, since it is the most environmentally friendly.

However, it should be taken into account that after applying the protective agent, other cladding (painting, varnishing) becomes impossible, so it is more advisable to use it for external work.

Primary requirements

When choosing an impregnation, in addition to looking at the photo of the impregnation, pay attention to the following indicators of the product:

  • does not clog the pores of the wood, allowing it to “breathe” normally;
  • does not lose its properties even at a high percentage of humidity;
  • deep adhesion (penetration) into wood;
  • the degree of water washout is low;
  • do not affect the structure of the tree.


Treatment wooden elements from all kinds of pests and external factors - an important part of building a house (gazebo, bathhouse).

As you can see, the question of which wood impregnation is best cannot be given a definite answer, because each of them has its own properties and applications. Just pick it up the right option, and then your home will not be afraid of any pests.
