How to paint the inside of a timber house. Painting a wooden house inside: step-by-step preparation and painting of wooden walls inside the house What color to paint a timber house outside

A house made of timber, recently built or under renovation, needs to address the issue of protecting the wood from environmental influences. Besides, new finish should improve the aesthetic qualities of the building. For these purposes, varnish or various types of paints of the required color and shade can be used.

Peculiarities

tree in street conditions a very unstable material that needs additional protection. Using paint for these purposes has its positive and negative sides. This finish has several important advantages.

Improved aesthetics. A house painted in the right color is pleasing to the eye and harmonizes with the surrounding area and the objects located on it.
Protection from aggressive atmospheric phenomena. This is primarily due to moisture: rain and snow, but also applies to strong winds, hail and other phenomena.
Biological protection. Wood is an excellent breeding ground for mold and other microorganisms; in addition, bugs can grow in it, and rodents also feed on it. High-quality paint will protect the material from these problems.

UV protection. Sunlight also has a negative effect on wood: it leads to drying out and fading of its natural color.
Possibility of maintaining authentic coloring. Glazing paint and varnish compositions cover the timber with a transparent coating, allowing you to fully enjoy its natural beauty.
Elimination of minor defects. Wood is a heterogeneous material, so its surface often contains pigmentation spots or other defects.

The negative aspects of paintwork materials include the following:

some types of varnishes interfere with the free exchange of vapor on walls, which contributes to their dampness and interferes with natural ventilation Houses;
paints and varnishes are flammable, which impairs fire safety.

What to process?

The main protective function is performed by the paint coating, however, in addition to it, special impregnations can be used that enhance the resistance of wood to various negative factors.

Impregnation

The composition, which penetrates deeply into the wood, is used exclusively to enhance the protective and performance properties of the material. The material must be soaked thoroughly. Impregnation performs a number of characteristic tasks, including the following:

improving the adhesive properties of wood before painting with main paints;
filling the porous structure of wood, cracks and irregularities in order to reduce consumption paint and varnish material– cost savings;
antibacterial and anti-bug protection for wood, for example, an antiseptic composition;
strengthening fire safety using fire retardant solutions;
reducing the impact of ultraviolet radiation on wood;
protection against putrefactive processes with hydrophobic compounds, enhancing the waterproofing of the material.

Types of paints for timber houses

The paint and varnish market is filled with a wide range of paints various types, each of which has its own characteristic features: positive and negative qualities. When building with your own hands, you must treat the surface of the lumber board before laying the bottom layer of paint. These steps are very important. For finishing works The following types of paint and varnish products can be used for the first time.

Latex

Modern means for painting surfaces different types, including wood, has excellent performance and aesthetic qualities. Separately, we can highlight such properties as:

high speed of finishing work is ensured by a short drying period - 1–2 hours for each layer;
strong adhesion to the wooden surface ensures a long period of operation of the coating without repair work;
environmentally friendly composition, absence of toxic components, completely hypoallergenic;
excellent protection from atmospheric phenomena: rain, snow, hail and others;
high resistance to ultraviolet radiation;

biological inertia - does not reproduce on it mold and other microorganisms;
high vapor permeability guarantees the ventilation of the facade, as a result there is always fresh air in the house, in addition, moisture that gets into the walls and interior spaces evaporates freely, without leading to dampness and damage;
good mechanical strength;
excellent elasticity - the surface layer does not collapse from the cycle of expansion or contraction when heated or cooled from high temperatures in the hot summer;
Alkaline detergents can be used to clean the surface.

The disadvantages of latex compositions include poor frost resistance, which makes their use on the facade impractical. The second disadvantage is relative, because fungus can multiply on its surface, but it is enough to apply an antiseptic to the surface to be painted, and this problem is solved.

Acrylic

Dyes of this type are widely used due to the good price-to-original result ratio, although such paints are not cheap. Other features of such compositions are the following:

the speed of finishing work is ensured by a short drying period;
powerful adhesion – adhesion to the surface ensures a long service life – about 20 years;
high resistance to aggressive weather conditions;
a weak, unexpressed odor makes it possible to work with paint without special protection;
high elasticity of the paint ensures the integrity of the surface layer during temporary deformations;

the color of the dye can be modified to the desired shade using special pigment additives;
high vapor permeability;
excellent moisture resistance;
safety, because the composition does not contain toxic components and does not provoke allergies;
resistance to sunlight.

Relative disadvantages include the rapid drying of the composition, in which open jar with dye, it begins to lose its optimal properties within 5–6 hours. Another difficulty arises when changing the color yourself; if you do not use a scale when adding color, it will be almost impossible to repeat the shade.

Oily

A classic wood stain with known strengths and weaknesses. Among characteristic properties You can highlight the following advantages:

strong adhesion;
wide choose color palette, the paints mix well and can be modified to the desired shade with pigment additives;
can be applied over the existing paint layer, except for water-based solutions;
good resistance to moisture and temperature fluctuations;
affordable price.

The disadvantages of oil paint include the following:

pungent characteristic odor;
long drying time of the layer - about 12 hours;
poor resistance to ultraviolet radiation;
low durability, on average you need to repaint every 3 years;
weak vapor permeability prevents the free exit of moisture from the walls and interior spaces, the former become damp and can rot, the latter may develop an unpleasant swampy smell, there is no natural ventilation of the facade - the air inside the house is more stuffy.

Alkyd

Alkyd paint is a paint and varnish product based on alkyd resins. Pronounced strengths are compensated by specific weaknesses. One of the main advantages is the affordable price. The advantages of such dyes include the following:

excellent moisture resistance;
short drying period of the layer;
excellent resistance to temperature changes;
maximum frost resistance;
long period of operation – 10–12 years;

The weaknesses are the following:

poor adhesion to wood;
must be applied to a completely dry surface, which is not always possible in outdoor conditions;
vapor-tight, there is no ventilation of the facade - free evaporation of moisture from the walls and interior spaces.

Rubber

One of the newest types of paint with unique performance properties without weaknesses, which are provided by its polymer base.

TO characteristic features paint and varnish materials include the following:

good adhesion to wooden surfaces;
the frozen layer is characterized by high strength and elasticity, as a result, during expansion and subsequent compression, the coating maintains its integrity, the surface is resistant to mechanical shock, loads, friction, vibration;
can be applied with any painting tools: brush, roller, spray gun;
fits perfectly, forms a smooth surface without sagging;
absolute waterproofing;
excellent vapor permeability, a house covered with rubber paint “breathes”, there is always fresh air inside, moisture from the rooms and walls evaporates freely, and they do not become damp with further consequences;

can only be dissolved in water;
a very fast finishing process, the drying period of the paint is from 30 to 60 minutes, the complete hardening period is approximately 1.5–3 hours;
excellent resistance to weather conditions;
the structure of the dye is resistant to sunlight, the shade does not fade throughout its entire service life;
safe composition - no toxic components, completely hypoallergenic;
long service life - about 10 years;
the paint is not cheap, but considering its excellent performance, the price-to-result ratio is one of the best.

Rubber paint has no characteristic disadvantages, but the application technology must be strictly observed, in particular the conditions under which painting is carried out, and the fact that it can only be applied in thin layers.

How to paint?

Outside

For getting good coverage It is not enough to choose high-quality paint; in addition, you need to adhere to the technique of their correct application. It is advisable to paint immediately after construction. First of all, it is necessary to prepare the tools that will be used to paint the timber. These include the following:

roller with a long handle;
medium and small brushes or spray gun;
grinding machine with fine abrasive;
antiseptic solution for primer;
paints and varnishes with which the timber will be coated;
brush.

In the future you need to adhere to of a certain order actions.

Surface preparation. Using a sander removes all traces old decoration, if the house is new, then the irregularities are removed. Next, the surface is cleaned with a brush from debris after sanding, dust, and dirt. Having a vacuum cleaner will speed up the cleaning process significantly. The more powerful it is, the better the debris will be removed.
Primer. The solution is applied in two layers, first carefully applying the composition over the entire surface, saturating every crack, bend, recess and other irregularities. It dries in about an hour, but it is better to check the drying time for a specific primer. Next, the second layer is applied.
Painting. The selected coloring agent is applied in 2–3 layers. Each subsequent layer after the previous one has dried. The final coating is often applied with varnish and also in several layers. It is better to paint with a brush in a horizontal plane with even, measured strokes, without collecting a large amount of dye on it. If a spray gun is used, painting is also carried out in several layers.

One of the most popular materials for finishing indoors and outdoors is wooden beam. This material has a lot positive qualities such as environmental friendliness, affordable price, practicality and presentable appearance.

To increase the service life of lumber, it needs the most reliable protection, since otherwise the material will begin to blacken and crack. Best option To protect a wooden surface is to paint the timber both outside and inside the house. Paint will be an effective and simple protection for rounded or log beams.

Types of coloring compositions for timber

Before starting painting work, it is recommended to select color scheme, and type of paint and varnish material. Paint for profiled or laminated timber should be selected taking into account the climatic situation in the region. In addition, in this matter it is necessary to consult a specialist. The main criteria that must be taken into account when choosing a paint and varnish material are its resistance to atmospheric or mechanical stress, service life and vapor permeability.

Transparent materials

This paint is also called the term. Its peculiarity is that such a solution does not hide the natural structure of the tree, but rather emphasizes its beauty. Such transparent paints are perfect for fresh rounded or log beams that do not have defects, cracks or dark spots on their surface. Of the transparent materials, the following compositions are most widespread:

Opaque paints and varnishes

These compositions are chosen if the design indoors or outdoors does not take into account the structure of the wood. Therefore, such paints have a specific color that can be selected in each specific situation. Opaque formulations are suitable for the following situations:

Today there are several types of opaque compositions:

Rules for painting timber

The main conditions for successful painting are the correct choice of paint and strict adherence to all work rules. When choosing paint, it is important to consider its color so that the painted timber matches other elements of the interior or exterior.

Preparatory work

At the preparatory stage, you must first thoroughly clean and dry the surface to be treated. When working with log houses made of laminated veneer lumber, it is necessary to take into account that they are practically not subject to processes of reducing the moisture content in the material. Therefore, they are ideal option for painting. First of all, the primer must be applied. It is best to use a fire-resistant and bioprotective composition as a primer. In addition, it is advisable to thoroughly treat the surface with an antiseptic.

Next is sanding, which is a mandatory preparatory step before painting. Proper sanding will make the surface smoother and at the same time reduce paint consumption. In addition, such a procedure will increase the depth of penetration of the varnish into wood material. As a result, the service life of the timber will increase significantly. It is recommended that sanding be carried out before you install the doors and windows. This is due to the fact that this stage of work is very dusty. Therefore, the presence of a respirator and glasses for protection is in in this case necessary.

Grinding affects the entire surface of the timber, including the ends. In some cases, it is necessary to paint the layer of wood covered with fungus. For grinding, it is recommended to use grinding machines or sandpaper with a degree of hardness in the range of 40-120. The final stage of grinding is polishing. It is carried out with the same tools as grinding work. The only difference is that for polishing it is used sandpaper with minimal grain.

Before you start painting glued or rounded timber, you should also seal the ends. These areas are much more susceptible to moisture compared to the side parts.

Therefore, experts advise treating the ends with acrylic sealant. This must be done both outside and indoors.

Painting stage

Painting of profiled or log beams should be carried out at an ambient temperature of at least +5 degrees. In addition, timber should not be painted during rainfall, so the surface of the wood must be completely dry before finishing. Otherwise, the method of applying paint to timber is standard and is carried out taking into account the instructions for the specific paint composition.

Paint quality is the main component of a quality exterior finish. country house. When choosing this composition, you should take into account its external characteristics, wear resistance and vapor permeability.

When thinking about how to paint a house made of timber from the outside, you must remember that painting for timber is not only decorative element, but also protection from negative influences external environment, ensuring safety and durability.

Painting a house made of timber should include: antiseptic treatment of wood and coating with varnish or paint.

Have Vacation home or a dacha is the dream of many residents of cities and especially megacities. The constant city noise, stuffiness, crowds of people on the streets are very tiring and make you want to retire to a quiet place and breathe fresh air, communicate with nature. Therefore, a comfortable country house is often not just a material property, but an urgent necessity of life.

Not everyone can afford to buy a ready-made country house. But the house is on suburban area you can build it yourself. It will cost an order of magnitude cheaper, and the result will be exactly what the owner of the future building requires. Especially if all the preliminary actions were done competently, thoroughly, sensibly: choosing a site, designing a future home, drawing up an estimate, planning construction work, choice of material.

The main thing, when starting to build a house, is to remember that this will require a certain investment of time, labor, and money. Starting construction country house, you need to carefully study the information about the materials presented on the market, consult with specialists and those who have already walked this path.

What is good about a house made of timber?

After the site has been chosen, the dimensions and layout of the future house have been thought up, you need to decide on the choice of material for it. This is the main question. Depending on what the house will be built from, the issue of the necessary foundation, insulation, etc. is decided.

Currently, one of the most popular materials for country buildings is timber: calibrated, glued or profiled. It is environmentally friendly, relatively inexpensive material with good thermal insulation properties.

Building a house made of timber does not require laying a massive foundation. Equipment will only be needed to deliver the material to the construction site. All this significantly reduces the cost of the house and facilitates construction.

In addition to the main house made of timber, you can also build an outbuilding, mezzanine, summer kitchen, bathhouse or sauna. This material is not used for outbuildings.

Insulation of the walls of a house made of profiled or any other timber is made from natural (moss, tow, etc.) or modern synthetic materials. To heat your home during the cold season, it is best to install an electric or gas boiler with a steam heating system.

Finishing a finished timber house

Proper painting of a timber house is a very important point. This issue should be addressed with special attention, because not only the appearance of the building, but also its safety and durability depends on this. A properly selected coating will protect the house from corrosion, rot, mildew, mold and other factors that shorten its service life. Waterproofing and protection against direct contact sun rays will also help preserve the original qualities of the wood and its natural color.

Basic rules for painting

Apply the antiseptic to the wood using a brush with hard natural bristles.

Exterior painting of a log house is carried out when the developer decides to refuse to use any finishing materials. Before painting a house made of timber, which has natural moisture, the entire structure must be thoroughly dried. Paints and varnishes adhere better to a dry surface.

After drying, the walls of the log house are cleaned of natural contaminants and thoroughly polished. This will improve the quality of the painting. Sanded dust is removed with a brush or vacuum cleaner set to blowing mode.

A primer (antiseptic) is applied to the surface prepared in this way. The primer must be applied to all natural or artificial irregularities of the timber: bends, cracks, small chips. The primer usually dries in no more than an hour. After this, it must be applied with a second layer.

Only after the primer has dried again can the paint and varnish composition be applied. It is also applied twice or thrice. Drying of each layer must be carried out according to the technical instructions on the packaging.

It is better to apply finishing materials with a brush or spray. The main thing is to remember that the brush should only move vertically. Paints and varnishes applied horizontally apply unevenly, do not sufficiently paint the timber and look very sloppy.

What materials are best to use

Choice of exterior finishes wooden house made of timber depends on the material used in construction. It would be more practical to cover the outside of a house made of calibrated or profiled timber with various finishing materials. In this case, you will not have to constantly renew the paint. It is better to paint a house made of laminated timber.

Typically, painting houses made of laminated veneer lumber is carried out using natural coloring compounds. This helps preserve natural look wood, its environmental qualities, and is also safer for home residents than, for example, synthetic compounds.

For exterior painting of a finished log house, paint compositions made from natural materials are used: clay, oil, water, etc. It should be remembered that painting a house made of laminated veneer lumber with synthetic paint compositions is extremely undesirable.

Facade paints can be matte or semi-matte, glossy or semi-gloss. For timber the following are used:

acrylates;
antiseptics;
oil paints.

Acrylic paint compositions are highly durable, easy to apply and do not require constant updating. Their main disadvantage is their high cost.

For work you will need: a roller, brushes, rags and so on.

Antiseptic compounds are made from organic substances, water and various additives. Dried antiseptics protect the painted surface well. The main disadvantage of antiseptic compositions is low stability and long drying time after application.

Oil paints are still considered the most economical and reliable. Their popularity is ensured by their high protective properties and low prices. The main disadvantages of oil-based compositions: long drying time and susceptibility of painted surfaces to fading, cracks and small chips.

After applying the paint and the painted surface has completely dried, it is recommended to also apply a layer of natural varnish. This will help fix the paint and further level the surface, because the varnish, as a rule, goes on without streaks.

When choosing a specific composition, it is better to give preference to products from well-known manufacturers. Their long-standing presence in the market for these products will be the key to the quality of the product offered. A well-known manufacturer is unlikely to want to reduce its rating with a low-quality product.

Interior painting of a wooden house

Painting the timber inside the house is also a very important point in the finishing work. Painted timber walls look much better and become more resistant to moisture, temperature changes, and mechanical damage.

It is better to use special paints for internal processing of timber. These compounds have high strength, various colors, stability and retain a bright and fresh appearance for a long time, providing additional protection against deformation.

You can emphasize the natural aesthetics of the timber on the inside of the walls using wax, drying oil or special oils. Minor natural imperfections in timber walls can be covered with mastic, which will not only help level the walls, but also give them a special velvety feel.

Properly selected and carefully applied paints and varnishes will protect and decorate a log house. A tastefully decorated interior will give a country house a special coziness. This will make such a house a wonderful place for the owner of the house, his family and friends to relax.

The simplest and surest way to protect wood from the destructive effects of moisture, the penetration of biological pests, ultraviolet radiation and other environmental aggression is varnish and paint. The process of wall renovation gives the building new look, attractive, elegant. External painting is durable oil compositions, protective impregnations, durable, reliable.

Features of exterior painting

Facade protected by paints and varnishes

Painting has two functions – protection and decoration. Decorating compositions can be transparent or with the addition of tint, a color that masks flaws and irregularities.

Paintwork dries differently. Quick-drying ones contain solvents or an emulsion base. Oil compositions require time to harden; driers will help speed up drying.

An important indicator is light fastness, the ability to maintain its original appearance for a long time without fading from sunlight. This parameter is of great importance for facade work, maybe even the main thing.

Important! Application paint coatings necessary if you do not plan to cover the walls with finishing materials, panels, or siding.

The paint and varnish coating does not interfere with the breathing of wood, air exchange is carried out through the ends of the beams and micro-slits of inter-crown joints, preserves the beauty of the natural wood pattern, and does not affect the ecological balance (transparent glaze composition). If the timber is of low quality or has significant flaws, varnish or paint will hide them, significantly improving the appearance of the house.

Material Selection Options

How to cover the outer walls of a log house is the main question. A comparative analysis will help you decide which paint to give preference to.

Conventional oil paints, familiar from childhood, have many advantages, but are of little use for facade work. Sensitivity to solar radiation quickly renders the painted surface unusable. The paint changes color, peels off, and restoration will require a lot of effort.

Alkyd paints are designed for exterior use, but they adhere well to metal or plastered surfaces; they apply unevenly to wood and do not adhere well.

Emulsion compositions are not afraid of the sun, but over time they are washed out by water, two or three slanting rains and the wall is bare.

Silicate paints for exterior finishing work are also not suitable for wooden surfaces; they are created for stone, concrete and plaster.

So it turns out that with all the wealth of choice there is no alternative to acrylic paints. The compositions are durable, do not fade in the sun, the surface coated with acrylic acquires hygroscopic properties. The compositions are convenient to use; until they dry completely, unnecessary stains can be washed off with plain water.

Paints can be matte or glossy. Shiny surfaces are not to everyone’s taste; moreover, all the cracks, knots, and other flaws appear on them. Matte surfaces are dull, but this drawback can easily be eliminated by properly selected tones or their harmonious combination. There are also semi-matte and semi-gloss paint formulations.

In Europe, it is now fashionable to apply any paint to timber walls and cover the top with high-quality, durable varnish. The houses look like jewelry boxes. Beautiful.

Advice! To ensure a high-quality, beautiful and durable coating, choose coatings from Zobel, Osmo, Tikkurila, Belinka. German, Finnish and Slovenian manufacturers are famous for the fact that their products are not only high-quality, but also environmentally friendly.

Technology for painting the facade of a timber house

Good preparation for the process is its integral part, the key to success and a guarantee of quality. First prepare tools and materials so as not to be distracted, because it is extremely inconvenient to constantly wash your arms, hands and clothes. You will need:

roller on a long handle;
a medium-sized brush and a small brush;
grinder with fine-grained abrasive;
primer antiseptic;
dye;
brush.

First, the walls are cleaned of dust and dirt, sanded, and the sanding products are removed with a brush.

Advice! Use a vacuum cleaner. He will help quickly, without special effort clean the surface. The more powerful the vacuum cleaner, the higher the guarantee high-quality processing walls.

The second step is the primer. It is applied in two layers, carefully saturating cracks, bends, recesses, and knots. The second layer should be applied after the first has completely dried, after about an hour and a half.

Then the walls are painted in several layers. The drying time for each paint is different; all subsequent layers are applied after the final fixation of the coating. The finishing layers are varnish, which is also applied in 2-3 layers.

Application of paintwork with a brush should be carried out with horizontal, even strokes or with a spray. Application of the product using a spray gun also occurs in layers.

Cost of paintwork

Is it worth inviting specialists, or is it better to save money by doing the work yourself? In different regions of the country, prices for this service do not differ much. The cost depends on the height of the building, volumes, number of layers, complexity and volume preliminary preparation walls

For example, painting 1 m² of the first floor area will cost 500 rubles, to this you will have to add the cost of 1 m² of sanding 300 rubles, finishing the ends 700 rubles, coating with protective agents 300 rubles. Total: 1800 rubles per 1 m² of wall. There is something to think about, especially if the house is large.

It's up to you to decide, our job is to give some useful advice in conclusion.

You should not stretch out the painting process, otherwise the tone of the areas may vary. It is difficult to achieve uniform color; you will have to use chemical bleach.

Remember, paint destroys the aroma of wood!

Use varnish products, they form a protective film that will become effective protection wood

For impregnation it is better to use natural mastics. This option is not applicable for laminated veneer lumber.

Many people use drying oil; dust does not stick to it.

Despite the modern abundance of various building materials, wooden houses remain traditional in almost all regions of Russia. From time immemorial, their log houses were erected in both urban and rural areas. Nowadays, the possibilities of using wood have expanded significantly - today, processed timber is widely used for the construction of residential buildings, frame structures from lumber and plywood or chipboard ().

When purchasing one of the protective solutions available for sale in a fairly wide range, you need to pay attention to the packaging label (label). It must indicate the area of its application, that is, a specific composition is intended for internal or external work.

Protective compounds can be transparent, preserving the completely open texture of the wood or giving it a glossy brightness or soft matte finish. However, there are also tinting solutions that make the material one or more shades darker.

There are several types of different solutions that can be intended to protect against various negative influences on wood - these are conventional and biomoisture-protective antiseptics, fire retardants, bleaching and primer compounds. To understand how they differ, it is advisable to consider each of them. This will make it easier to make the right choice.

Prices for wood antiseptic

antiseptic

Antiseptic solutions designed to combat fungus and mold that has appeared on wooden surfaces, as well as to prevent the emergence of new formations. These compositions, in turn, are also divided according to different criteria.

So, you can find two types of antiseptics on sale - impregnations and coatings:

— Impregnations are intended for deep penetration into the wood structure. When purchasing this version of the solution, you need to carefully study its composition, since some of these treatment agents are very toxic;

— Coating solutions create a film on the surface of the wood and protect it from moisture. They are especially relevant for covering walls in rooms with high humidity, for example, in a bathroom or bathhouse.

Antiseptic solutions are produced on different bases, and according to this criterion they are divided into the following:

— Water-soluble compounds are environmentally friendly, so they are excellent for treating indoor walls. They are usually used for paints also made at water based. A significant disadvantage of such antiseptics is that over time their protective qualities decrease.

— antiseptics made on an organic basis have high protective properties. However, they are more suitable for the facades of wooden houses, since they contain toxic components and are also unsafe in terms of flammability during application and before drying.

— Oil solutions of antiseptics are most often used for facade surfaces, wooden cladding of a balcony or loggia, especially if the house is located in a region with a harsh climate.

— Combined solutions consisting of oil and high-carbon components are used to treat both external and internal wooden surfaces. Moreover, they are also suitable for rooms with high humidity, providing their surfaces with high-quality protection.

The last option of antiseptics is the most expensive, since, in fact, it becomes a universal remedy used in any areas of construction and finishing.

Biomoisture-protective antiseptics used as effective measure protection against fungal growths, mold and insects harmful to wood. This type of antiseptic creates a protective barrier on the surface of the wood and also serves as a decorative coating. Therefore, the biomoisture-proof solution can be called universal, since it performs two functions at once.

Thanks to these properties of the antiseptic, not only money will be saved, but also time for painting. It is these solutions that are in high demand among owners of wooden houses.

Fire retardants are used to give wood higher resistance to fire, that is, material treated with such a composition is able to withstand exposure to open fire for a long time without igniting.

Fire retardants are divided into two groups according to their reaction to fire:

— One group of solutions contains salts, due to which, when wood is exposed to high temperatures, gases are released that can prevent rapid combustion.

— The second group of fire retardants blocks the flame by foaming, which occurs when wood is heated to elevated temperatures and creates a protective coating on it.

More effective fire retardants, according to experts, are those that contain sodium salts, as well as orthophosphoric, pyrophosphoric and tripolyphosphoric acids.

Biopyrenes are called impregnations that combine the functions of both a fire retardant and an antiseptic. Similar solutions can be used to treat walls from the inside and facade.

Due to the fact that this product is a complex consisting of all the components necessary to protect wood, using it you can save some money, time on work and on waiting for several layers to dry. different solutions. So the costs are likely to be justified.

Biopyrene prices

biopyrene

Primer on wood is another effective protective agent with which preparatory work is carried out before painting. These solutions are not only designed to prevent various manifestations and effects destructive to wood - they also create good adhesion between the surface of the wooden wall and the applied decorative layer. Water-based wood primers can be transparent, translucent or opaque. According to this criterion, they are selected depending on what effect is planned to be obtained as a result.

For example, if you plan to paint primed walls with a thick layer of paint, then what type of transparency primer you use to cover the wood does not matter. In this case, rather, it is necessary to take into account only what is more smooth surface will give an opaque version of the soil. Transparent compounds work like impregnation, penetrating the structure of the material and filling its pores, but they do not have the property of creating a protective layer on the surface of the wood.

However, whatever primer is used, it creates good foundation for adhesion between wood and paint.

Wood bleaching products are used to remove various manifestations from its surface that spoil the appearance of the entire wall - these can be blue, stripes or dark spots. Simultaneously with the removal of the above-mentioned flaws, these compositions also perform a protective function.

Bleaching solutions can be one- or two-component. The second version of the compositions is combined and mixed immediately before applying them to the wood. The formulation of some of the products provides for them to be washed off after a certain period indicated on the packaging, while others remain on the wood for painting as an antiseptic. Therefore, before purchasing one or another type of bleach, you need to pay attention to the packaging, which contains instructions for using the solution.

Varnish as a protective and decorative agent

As a protective agent for wooden walls In addition to the above mentioned products, varnish solutions are used, which can also be made on various bases. To know which of the existing varnishes are suitable for indoor use, you need to consider each of them in more detail:

Acrylic lacquer consists of polyacrylates and is organic or water based. The solution is an environmentally friendly product without strong smell, and therefore it is often used to cover the surfaces of not only wooden walls from the inside, but also furniture.

However, it must be taken into account that the layer formed by this type of varnish is not highly resistant to abrasion. This means that the coating will have to be updated quite often, and this is especially true for furniture accessories.

Polyurethane varnish It is made on a water basis, but despite this, it has high strength characteristics, including abrasion resistance. The composition of this protective agent is environmentally friendly and almost completely odorless after drying, so it is perfect for application to wooden walls inside the house.

Some experienced craftsmen It is recommended to add hardening agents to the polyurethane solution to extend the life of the finish. Due to its high strength characteristics, this varnish is often used to cover wooden floors and parquet, so it is also fully suitable for walls. However, the price of these products is quite high, and this factor is the main disadvantage of this material.

Alcohol varnishes and polishes are able to create a durable glossy layer on the surface of the wood. However, despite their high strength, compositions based on this basis are not resistant to moisture, so they cannot be used to cover walls in bath rooms, in the loggia and on the balcony, as the coating layer will begin to peel off.

Varnishes are made based on natural resins, so their prices are quite high. This circumstance, coupled with low moisture resistance, determines that such compositions are not in high demand.

Nitrocellulose varnishes consist of organic solvents and cellulose nitrate with the addition of synthetic resins to the solution.

This type of varnish is divided into two varieties:

— One of them is intended for preparatory work, that is, it creates the basis for the outer layers.

— The second one is itself a decorative coating.

They are distinguished by the digital markings applied to the packaging. Typically, preparatory solutions have the property of drying quickly - this quality is provided by the manufacturer to avoid delays in the work. Therefore, when purchasing this composition, you need to pay attention to the instructions printed on the packaging with varnish.

Nitrocellulose solutions create a fairly durable coating layer on the surface of wooden walls, which is transparent and therefore does not change the natural color of the wood. Therefore, if you intend to preserve a beautiful textured pattern internal surfaces wooden walls, then this type of varnish is well suited for this purpose. True, it is necessary to work with such compositions with special caution - they are extremely flammable in their uncured form (before the nitro solvent evaporates), and will emit a pungent odor before drying.

Oil varnishes are made on the basis of artificial or natural resins, in addition, they also contain a modified natural oil, driers and solvents. Varnishes of this type penetrate well into the wood and form a durable protective layer on its surface, giving the wood a warm ocher tint.

The solutions are well suited for interior finishing work; they cover wooden walls, floors, and furniture.

Alkyd varnish It is made on the basis of glyphthalic or pentaphthalic resins, to which driers are added. Since this type of varnish contains oils used as solvents, they are also often called oil-based. However, the alkyd version of varnish differs from oil varnish in its higher physical, technical and operational characteristics, so it is successfully used not only for interior but also for exterior decoration.

In addition to alkyd varnishes, alkyd-urea solutions consisting of alkyd and amyl-formaldehyde resins are also available for sale. This type of varnish can be called two-component, since its drying is only possible when acidic hardeners are added to the mixture. This varnish is mixed immediately before applying it to the surface of the wood, since after preparation the solution remains suitable for a very limited time, and after it has hardened it will no longer be possible to dilute it.

This type of varnish is easy to apply and, after hardening, forms a durable protective layer on the surface that is highly wear-resistant. Thanks to this property of alkyd-urea varnish, it can be used not only for covering walls indoors, but also

Paints for finishing wooden walls

In order to paint the inside of a wooden house, paints made on any base are suitable. In our time Various types This material is presented in specialized stores in a very wide range. And one of the most important criteria when choosing a composition should be its safety, that is, the paint should not emit harmful toxic substances both during its application and during use of the premises.

Therefore, when purchasing any paint and varnish material, you need to pay attention to its characteristics, which should be presented on the packaging. In addition, it is recommended to obtain information from a sales consultant.

So, in specialized stores today you can find the following paints for finishing wooden surfaces:

are quite popular, since with their help you can cover the wood with a thick layer of paint, or you can make it translucent, thereby preserving the textured pattern of the wood. If the latter option is chosen, the paint must be diluted with water to the required consistency.

Water-based solutions are distinguished by the absence of a sharp unpleasant odor and the fact that they do not emit toxic fumes harmful to humans. Therefore, they can safely be called environmentally friendly pure material. The layers applied to the prepared surface set well and dry quickly, but are inferior to varnishes in their strength and wear resistance.

Prices for silicone paint

silicone paint

Silicone paints They are a solution of silicone resins, and thanks to them, they create a reliable and durable coating on the surface of the wood. The paint composition has excellent technical characteristics, it is inert to mechanical stress and has good vapor permeability, that is, it allows wooden walls to “breathe”.

Moisture-resistant silicone film is resistant to abrasion and ultraviolet radiation. The applied coating is distinguished by enviable durability and is not only protection for the wood, but also a way to hide some flaws on its surface. The coating does not crack when the walls shrink, as it has good ductility.

Silicate paint compositions are made from " liquid glass", therefore they have a large number of positive characteristics. They are highly resistant to ultraviolet rays, high humidity, low and high temperatures, as well as open fire.

Silicate paint is an environmentally friendly product, since it does not contain substances harmful to humans and does not emit toxic fumes. Therefore, this type of material is excellent for covering internal surfaces, not only wooden ones, but also those made of other materials. Considering all the characteristics of this finishing material, we can conclude that it is well suited for rooms where conditions may arise that increase humidity, for example, an unheated balcony or veranda.

True, silicate compositions are completely incompatible with finishing solutions made on a different basis. That is, in case of repainting, it is necessary either to use silicate paint again, or to clean the surface to the very base.

are made on a water basis, but have characteristics exceeding those of oil-based compositions, therefore they are able to give wood reliable protection and maintain its natural color. Due to their elasticity, paints have excellent adhesion to surfaces; they do not deform or crack.

The paint can be used to paint both internal and external surfaces of a building.

Alkyd enamel used for painting both facades and interior wall surfaces. It creates a protective glossy or matte layer on the wood, making it smooth and aesthetically pleasing.

However, this composition also has its drawback - over time, alkyd white enamel turns yellow, and paint that has color fades, so for painting walls, for example, a balcony located on the sunny side, or that constantly receive a “portion” of sunlight, use it is not recommended.

Oil paints have a considerable number of advantages compared to other compositions and are applicable both for internal and external outer covering wooden surfaces. High-quality solutions are highly resistant to external mechanical influences and high humidity.

The obvious disadvantages of oil-based paint compositions include their long drying period, low resistance to ultraviolet radiation (over time, the coating begins to crack and peel) and air tightness. This type of paint is most often used for coating facade surfaces, but even then - with fairly frequent updating of the finish.

Wax natural paints or liquid wax are produced on a flax base and have been used to cover wood for decades, so they can be called a traditional material. Wax is well absorbed into the wood structure, making it waterproof.

The solution can be clear or tinted. If you plan to preserve the original color of the wood, then choose a transparent wax option, and if you need to darken the wooden walls, then you should use a tinted solution. Wax paint is easily applied to the surface, but acquires the chosen shade only after complete drying. Therefore, it is recommended to first apply a similar composition to a small area of the wall and wait for it to dry to make sure that the optimal paint tone is chosen.

Useful recommendations for purchasing paint and painting

When choosing and purchasing paint for wooden walls, it is very important to pay attention to the date of manufacture of the composition and the availability of certificates confirming its quality and sanitary compliance. If the seller cannot provide documents for the product, and the production date is not stamped on the packaging, but is written on paper and pasted on top, so to speak, interrupted, then it is recommended to immediately refuse to purchase such paint, especially if a fairly expensive version is purchased.

The fact is that if the paint is expired or frozen, then it may simply not lie on the surface, even if it is well prepared, and you can determine the quality of the composition only by opening the package and trying to apply it to the wood. For example, it will not be possible to paint anything with a frozen solution, since the paint will most likely curdle and have the consistency of liquid cottage cheese.

If the paint is of high quality, it will be easily applied to the surface, which means that painting the walls can be done by a person who has never even performed such repair work before.

First thing to note. It is a common phenomenon that many homeowners, when doing home repairs or repairs on their own, are careless preparatory stage work because they consider it unnecessary. However, if the basis is decorative coating will be uneven and untreated with protective agents, you should not expect the desired result. In addition, after a short time, even defects that are invisible immediately after completion of the work will begin to appear, for example, such as blue discoloration, blackness of the wood, or “resin pockets” near knots. Therefore, the preparatory process must be considered mandatory and carried out as efficiently as possible.
When treating wood with one of the protective compounds, it is necessary to very carefully process the end parts of logs or beams if they face the rooms. If the walls of the house are lined with clapboard, then it side surfaces must also be thoroughly treated with antiseptic solutions.
All protective and coloring compounds are applied to wooden surfaces in thin layers along the grain, otherwise their absorption into the wood will be uneven, which will negatively affect the overall appearance.

To ensure that there is no excess paint on the brush, and that it does not flow, but lies flat, it is recommended to use a simple device consisting of two stationery or ordinary rubber bands. One of the rubber bands is put on the bottom and top of the can, and the second along its diameter. The second elastic band will hold the first one, preventing it from sliding to the side.

After dipping the brush into the paint, press it against the stretched rubber band, leaving excess solution in the container.

When applying paint to the surface of wood, do not try to cover it with a thick layer at once, as the painting will turn out sloppy. If you plan to get an opaque surface, then you should apply the paint in several thin layers, each of which should be applied after the previous one has completely dried.
When painting walls sheathed wooden clapboard, the last top coat is best applied starting at the top and gradually moving down - this method will help make the surface of the wall smooth.
Paint can look different in a can and on the wall, so it is recommended to do a test paint job, that is, apply the solution to a small section of the wall in an inconspicuous area. It is best to choose the lower corner part of the surface.
In order for the decorative layer to lie evenly on the surface, experts recommend adding a color to the primer that is one or two tones darker or lighter than the base color.
The optimal temperature for painting surfaces is 22÷25 degrees. You should not carry out this process in hot weather, as the paint will dry too quickly and therefore unevenly. If the temperature is too low, the fluidity and hiding power of the compositions deteriorate, and the drying period increases.

Step-by-step instructions for painting a wooden wall indoors

By adopting all the little tricks listed above, it will be easier to deal with preliminary stage and painting walls. Having prepared all the tools necessary for the process and workplace, you can move on to the finishing itself.

The bulk of the work involves painting, which is why they require a more detailed description.

Illustration	Brief description of the operation performed
	For preparation and painting, you need to have at your disposal some of the tools shown in the illustration. In addition to them, you will need a grinder with replaceable abrasive paper blades and, possibly, a grinder with an iron brush. If the wooden wall has an old coating, you can use it to remove it. construction hair dryer and a scraper (spatula).
	The first step is to clean the surface of the old paint coating (if there was any). To do this, the paint layer is heated until it softens and peels off from the wood, and then is removed with a scraper or spatula. This work is quite time-consuming and labor-intensive, but it must be done efficiently, otherwise the remaining paint will appear through the new decorative layer as unaesthetic irregularities.
	If the wall does not have an old coating in the form of a paint layer, but has acquired an unrespectable appearance during use, or wallpaper has previously been glued to it, its surface must be thoroughly cleaned by removing the top thin layer wood
	Restoration of such a surface is carried out using a “grinder”, on which a brush with soft metal bristles is installed, and then grinder with first coarse-grained (P80÷P120) and then fine-grained (P150÷P180) sandpaper attached to it. In addition, cleaning the wall or its individual areas protruding above the general surface can be done using an electric plane.
	When the wood is cleaned, its surface should be sanded with a fine bristle brush or sandpaper. In the case where a wall made of new wood is being prepared for painting, it also needs to be sanded smooth. Cleaning and polishing difficult places, for example, between two logs of a log house, can cause a lot of difficulties. But here, as they say, nothing can be done - you will have to “sweat” if you want to get a high-quality result.
	If grinder no, you will have to sand the walls manually - this is very difficult and long process, so it’s still better to purchase a specialized tool, since it will come in handy more than once in a wooden house. The sanded surface must be cleaned with a vacuum cleaner to remove any dust generated during the sanding process.
	The dust-free wooden surface is then coated with one of the selected protective agents - it can be an antiseptic and fire retardant, or one of the compositions described above. This operation can be carried out using a roller, a wide brush or a spray gun, depending on the topography of the wall and its area. If it is log, then the work will go faster if you carry out this process using a sprayer. At the same time, we must not forget about the need for increased precautions - many primers protective compounds before absorption and drying - very toxic.
	As a preparatory, and sometimes even the main decorative layer, one of the types of varnish is used, which is applied with a wide soft brush.
	If, after the primer has dried, you plan to apply paint or a dark tinting varnish to the surface, then you should protect the ceiling from contact with the solution. To do this, it is recommended to stick on the upper edge of the wooden wall on the ceiling. masking tape, which can be easily removed upon completion of work and does not damage the plastered or painted ceiling surface.
	To paint wooden walls, you will definitely need a soft brush and roller. The roller will significantly speed up the work, as it covers a large area of the wall at once and evenly distributes the paint solution over it. True, this is only possible on flat surfaces - when painting a log wall, a roller will not be a great help.
	A brush is needed for painting hard-to-reach places, for example, corner areas or horizontal joints between logs. It is recommended to paint in two to three approaches, but each layer must cover the entire area of the wall, otherwise the paint will lie unevenly. Each subsequent layer is applied only after the previous one has completely dried.

So, the process of painting wooden surfaces in a house is a very labor-intensive, large-scale task, which, however, any owner must cope with. And for successful work, in addition to your own desire, you must:

Have necessary tools good quality.
Select and purchase high-quality primers and paints for preparing and painting surfaces.
Carry out everything carefully, without simplifications preparatory processes, without convincing yourself that “it will do.”
Do the painting without rushing and without trying to complete it in one go, that is, do not apply the paint in one thick layer - this approach will result in nothing but drips, overuse of paint and a sloppy surface.

If you strictly adhere to all these conditions, the coloring will definitely turn out the way it was originally intended, that is, neat and uniform, and the finish will last as long as possible.
