Varnish for lining inside the house - instructions for use. The better to process the lining inside the room What colorless varnish to cover the lining inside the house

Wood is one of the few finishing materials that needs processing after installation on walls and other surfaces. The most common lining method is lining varnish, which can be used indoors and on the facade.

Types of varnishes

Any varnish is a transparent or translucent material that covers wood in order to protect it and improve its external aesthetic qualities. Before choosing which varnish to cover the lining inside the house, it is necessary to compare the advantages and disadvantages of all means of this type.

The classification of these materials is carried out according to composition, properties and area of use. There are varnishes for internal works and outdoor, they differ from each other in some qualities (for example, the street covering must be indelible) and smell. At the place of application of the coating are divided into:

Parquet. Used to cover wood on the floor. You can choose any color and properties (gloss, matte surface). The key difference from other products in this series is its high resistance to mechanical stress: friction, walking, etc.
Furniture. For furniture finishing, special compositions are used that provide a long shine and a constant color of wood for many years of use. Most of them are made on the basis of wax;
Construction boats. They have an increased coefficient of resistance to moisture, which allows them to be used in shipbuilding. Many craftsmen use such tools to decorate utility rooms (baths, garages) or facades of residential buildings;
Decorative. The widest group. Designed exclusively for room decoration. This varnish can be glossy or matte. Often indelible with water and with excellent antiseptic properties. It is used to cover walls in residential buildings, utility rooms (on the loggia, dacha, in the steam room, etc.), sometimes for finishing the facade.

Varnish is a coating for lining, which, depending on the main component, performs not only decorative, but also protective properties. Depending on the composition, they are:

Alkyd;
Acrylic;
Nitrolacs;
Oil;
Epoxy;
Polyurethane.

Let's consider the features of each of the groups. Alkyd varnishes for covering wooden lining can be used on the balcony, in the corridor, living rooms. They are versatile, possess high rates resistance to external aggressive factors ( high humidity, temperature differences). These paints and varnishes penetrate deep into the wooden structure, therefore they dry out for a very long time - sometimes the curing time of the coating reaches 3 days. The disadvantages also include the high cost of the coating and the likelihood of fire.

Clear acrylic lacquer is the most sustainable finish wood panels... They preserve and prolong the natural color of the wood, while helping to protect it from fire and decay. But they have low indicators of resistance to moisture. For example, if acrylic-based varnish is used in the bathroom or on the balcony, then it can harden within 4 days. To speed up this process, it is recommended to use formulations with increased level crystallization.

Acrylic varnish for finishing the lining is water-based (aqua) and solvent-based. Aqualak (Tikkurila, Pinotex, Poly R and others) has more wide range use in view of the fact that it does not deform the wood. At the same time, the solvent is more resistant to irritants and can even be used to cover the floor.

Transparent nitro lacquer does not have a pronounced odor and dries very quickly, at the same time, its price is almost two times lower than that of options with an acrylic or alkyd base. It is used to paint Euro lining inside and outside the house, but it has a significant drawback. The product contains poisonous substances that can cause poisoning. After the mixture has dried, they are harmless, but it is not recommended to heat walls with such a coating, and it can only be applied in a protective mask.

Oil varnishes are also called impregnation. They are rarely used independently, they provide primary processing of wood. Depending on the oil and resin in the composition, the coating can have different colors: from light brown to dark chocolate. After hardening, they form a hard film on the wall or ceiling, which is easy to clean. On top of it, further processing is carried out. Among the advantages: moisture resistance, protection of wood from UV rays, prolongation of the durability of the coating. The disadvantages include a high level of fire hazard.

Epoxy varnish can be used to paint walls, ceilings, floors, furniture and other surfaces. It has excellent strength and moisture resistance properties. Due to this versatility, it is very popular with professional and home craftsmen. You can choose any colors, it is easy to use and apply, very flexible. Among the disadvantages is the relatively high price of coverage - from $ 3 for square meter(at optimal consumption).

Polyurethane matt and glossy varnish is the most popular and affordable option of all of the above. It is formulated with synthetic fibers that facilitate easy application of the mixture and increase the durability of the wood. Depending on your needs, you can choose a paint-like varnish to change the shade of the wood, or use a transparent version. It can be white, brown, dark red, etc.

Application

To renew the wall covering, you need not only to know how to remove the varnish from the lining, but also how to use the coverings correctly. To begin with, the walls (floors, ceilings) are washed out; for this, a damp cloth with special wood cleaners is taken. This is necessary to remove dust and dirt from wood pores.

Further, it is removed old layer coatings (if any) or the lining is sanded. For this, they are used as special grinders and low abrasive sandpaper and metal brushes. This is necessary to level the surface and eliminate chipping. After that, you need to paint the wood with linseed oil. You can buy it at any hardware store. The drying oil fills the microcracks in the lining and helps to improve adhesion; after the drying oil dries, a primer is applied to the walls.

How to paint lining with varnish:

The movement should be along the woody structure, preferably from top to bottom. The first layer is made dense, but without streaks;
For painting, you can use both brushes and rollers, but it is more convenient to work with brushes. The material of the working part of the tool must be made of natural wool;
Experts recommend making 3 layers of varnish, the last one being the thinnest. He is leveling. After the room is left to dry and ventilate. The coating will need to be renewed every 3 years to avoid cracks and chips.

You can buy varnish for lining at any hardware store, on average, the price ranges from $ 6 per can. The cost may vary depending on the brand and purpose of the product.

One of the popular surface finishes wooden house or dachas - sheathing with thin boards, known as lining. As a result, rooms are given a cozy feel that allows you to relax in a healthy, environmentally friendly environment.

The impregnation for the lining inside the house, which can be purchased in specialized stores and applied in accordance with the instructions of the manufacturers, helps to ensure the safety of the interior unchanged for a long time. There are other products that can be used to coat wood.

Why use impregnation?

Some owners have doubts about the need to impregnate wood lining inside a suburban building. If the boards are not covered, changes will be noticeable on them after a while. With weak ventilation, blue will appear on the lining, as a result of intense solar lighting it may turn dark gray.

The blueness is due to the action of microorganisms, which can be eliminated with the help of active oxidants, such as chlorine. The procedure is not very easy to perform and is accompanied by the release of an unpleasant odor.

Plaque gray from the sun can be removed by mechanical grinding of the lining, but the positive effect will not last long. It is more advisable to carry out the processing immediately after finishing the finishing, so that later there will be no problems.

In addition, the coating transforms the wood, makes the interior special. The lining, covered with a waterproof impregnation, can last longer even in an irregularly heated, damp room.

Types of compositions

How to cover the lining inside the house is an easily resolvable question, because there are many products on sale for different climatic zones and types of buildings.

Composite impregnations are designed to perform several functions, the main of which are the following:

lower flammability,
protection against germs,
improvement of appearance,
increased mechanical strength.

There are products designed primarily to protect the lining, and compositions created for a decorative effect. Many drugs perform several functions equally successfully.

What is the best way to process?

There are a large number of products on the market for processing wood materials. Information about the most popular drugs will help potential buyers to make purchasing decisions easier.

Fire retardants

The lining located inside the house next to heating devices must be protected from possible ignition. For this purpose, they are used, which are not easy to apply on their own.

It is much more convenient to buy a lining for a summer residence, pre-impregnated with fire-fighting substances. In rooms with a moisture concentration not exceeding 70%, the lining can be coated with solutions with moderate resistance. Inside the house, the applied composition will last for a long time, it costs much less than an weather-resistant solution.

Antiseptics

Microbiological impact is a strong risk factor for wood spoilage. They get rid of it with the help of antiseptics. Antimicrobial solutions, which can be impregnated with wood, cope with biological contamination, prevent the appearance of new foci of mold and decay. Antiseptics have a pungent odor that does not disappear for a long time, and you need to pay attention to this when buying, after studying the reviews on the product.

Preparations with a higher cost than conventional disinfectants can not only protect against microorganisms, but also simultaneously improve the aesthetic impression, increase the ability to repel water molecules.

Stains

Special liquids based on water, alcohol or organic solvents that penetrate deep into the wood, create a specific color or shade, are called. The term has a foreign synonym - stain. The solutions do not protect, but only tint the wood, although there are special types of expensive wood stains with a pronounced protective effect.

Note! In any case, after applying the stain on top of the lining inside the dacha, it must be varnished. Otherwise, the tree will not retain its original appearance.

Sometimes there are dark spots on the wood planks, the appearance of which remains a mystery. You can treat such places with bleach, choosing the concentration and exposure time well. You can practice on the waste lining, see how many tones the wood base is lightening, and draw the appropriate conclusions.

Lucky

Varnishes have a good protective effect in relation to the lining inside the cottage or residential building. They can also be used to cover the lining to achieve a decorative effect. Acrylic-based varnish compositions decorate the surface well, create a biological barrier on it.

Due to the minimal allergenicity indoors, it makes sense to use an aqualak. It dries longer than solutions in organic liquids, but has greater health safety. With scuba divers it is possible to create a completely or slightly matte as well as glossy surface.

If you add color to the solutions, you get a colored product with the desired shade. Outside, such a composition will not last long, therefore it is not recommended for outdoor use. Water based varnishes create a vapor barrier to prevent contamination of open pores.

Note! In some modifications of the aqualak, there are additives of antimicrobial action, which significantly improves the safety of the lining inside the house.

In other compositions, substances are introduced that level the effect of UV rays. It makes sense to use such formulations to cover walls that are illuminated by the sun during most of the day.

Alkyd varnish solutions have great durability, after which the coating can be preserved for 10 years. Usually inside a wooden house, summer cottages with such compounds are recommended to cover the floors. Lovers of permanent color schemes of rooms can apply alkyd varnishes to the walls. If the desire to change the interior arises earlier, you can spread a varnish of a different color on top.

Paints

To cover the lining inside the cottage, a huge group of various paints for wood can be used.

The "veteran" of the market is oil paints of all colors and shades, which stay on a dry surface for more than 7 years. After the expiration date, the paint layer may discolor and flake off, then the painting will have to be repeated. Pre-treatment of the base with linseed oil improves the fixing of pigments on wood. Drying vegetable oils cover all pores polymer film, which impairs vapor permeability, but improves the quality of the coating.

Note! Oil paints- most cheap stuff for covering the lining, which has disadvantages.

Due to the clogging of the natural pores of the tree, the indoor microclimate worsens. During painting, active evaporation of the solvent, which has an unpleasant odor, occurs. Vapors of organic liquid are harmful to health, therefore painting can only be carried out in summer with open windows and doors.

Acrylate paints are also made on a pungent-smelling base, painting should be done carefully, with careful ventilation of the rooms. Acrylate paint is applied faster and easier than oil formulations, it forms an elastic, elastic coating that lasts a long time and firmly. The walls inside the cottage, painted with acrylates, tolerate winter cold well, even in the absence of heating for a long time.

Oils and waxes

In addition to drying oil, which is made from drying oils, others that are well absorbed by wood are used to cover the lining inside the dacha. They form a matte or shiny surface when gently rubbed in and then polished. Waxes have a similar chemical structure, the difference lies in the replacement of ester glycerol with a higher monohydric alcohol.

Waxes are very durable, form a shiny, even surface when properly distributed and applied to the lining. Wax coatings can last for decades if they are not under heavy mechanical stress. Glaze wax is sold ready-to-use. Hard waxes before application, soften by melting in a water bath. To distribute the wax evenly, the lining must be primed first.

A good result will be obtained if the boards are coated with a mixture of wax and oils that combine the advantages of both components.

Features of applying impregnations

There are several types of lining, they differ in the number and shape of joints on the resulting surface. Depending on this, it will take a different amount of effort to prepare it.

In any case, before you cover the lining with any means, you must carefully look at all the boards. In the presence of dark spots carry out local clarification with bleach. Then the entire surface can be lightly rinsed with a diluted soda solution, wait until the water has completely evaporated. Only then can the tree be treated with soil and the basic composition, or immediately by impregnation.

Cracks are covered with putties for wood, everything is thoroughly cleaned with sandpaper.

For a more effective fixing of the decorative layer, the wood is subjected to a primer. It is necessary to distribute the primer very carefully in the seams. To apply primer over the main part of the area, you can use a spray gun; in the joints it is better to prime with a brush.

Each product has its own application features, which are necessarily described in the manufacturer's recommendations. The accompanying documents must be well studied, the compositions must be prepared in accordance with the instructions. All funds are applied in several stages; each subsequent stage can be performed only after the surface has dried, while the final layer should be the thinnest. Compliance with these rules will help you get a reliable and beautiful coverage.

Both internal and external wall cladding with clapboard is an excellent solution for the owner who cares about the condition of his home. Interior decoration will create a cozy and healthy atmosphere in the room. The external one will protect the facade of the building from unnecessary damage.

In this article, we will dwell on why to process the lining, what protective compound is it better to do, what is the application technology paints and varnishes, as well as how much you need to count on when painting.

How to effectively protect a tree

How to process the lining inside the house? This question is often asked by the owners who used wood.

Today, the processing of lining inside the house is not a problem. You just need to choose the right protective coating that will fit a particular room.

Some are more suitable for rooms with high humidity, others perfectly protect the boards from ultraviolet rays, and some generally increase the strength of the wood and prevent the risk of premature abrasion.

But also an important factor in processing is that protection should look good on the boards... It should not distort the natural structure of the tree. On the contrary, its task is to emphasize the naturalness of the material used and harmoniously combine with the rest of the interior.

Most often, to protect wood, the following substances are used:

Antiseptic
Bio oil
Primer

Types of varnishes for woodworking

Speaking specifically, how to process the lining in the house, then the choice of protective mixtures is quite large.

1. Ground

This mixture is not only a complete primer, but also an excellent bio-protective agent. An antiseptic primer is suitable for treatment both indoors and outdoors.

Moreover, the use of a primer is appropriate even on the affected tree. The primer, along with the textured finish that is designed for protection, will prolong the durability of the board and keep it neat and tidy.

2. Protective and decorative

One of the main qualities of the mixture is that it gives the desired color wooden surface... By the way, protective and decorative coatings are an innovation in the paintwork materials market.

But it is very important that even with such a composition, the tree structure is still visible.

They are very convenient to use, since they do not need to use a primer first, because they already contain antiseptics. Moreover, they are resistant to fading and temperature extremes.

Some species are suitable for use on damp wood. They are great for indoor and outdoor use.

The finish has a soft semi-matte finish. According to the manufacturers of these funds, the warranty is 8 years.

3. Aqualaki

Continuing to talk about how to treat the surface inside the house, you should definitely pay attention to water-based products. For work inside the house, professionals recommend an aqualak.

Pros of using scuba diving:

Odorless
Fast intercoat drying
It contains no organic solvents

For external work, products with hydrophobizing additives are suitable, which protect wood from dirt and moisture... Of course, it is not from the budget class, but the owner is provided with durability, ease of maintenance.

4. Oils

Quite often, the surface of a tree is treated with oils or their combined mixtures.

Oil coating provides protection against contamination, moisture and dust, due to the fact that it penetrates deep into the structure of the tree.

An important plus when using varnish is that there is no solvent aroma, and you can only feel the smell of the plant on the basis of which the oil is created. Moreover, this composition is very easy to tint, with the help of which you can get the desired shade.

Painting tools

We answered the question of how to process the lining, but one more remained: how to process the lining inside the house?

Its importance lies in the fact that all compositions are different in consistency, therefore, you should be especially careful about the selection of tools so that the application of a protective layer is convenient and effective.

An indicative list of what is required when applying paint and varnish mixtures:

Napkins
Construction scotch tape
Scotch bright
Sandpaper (# 240)
Tray for paint or varnish
Roller
Brushes

Whitening

This process is the first stage when painting with any compound.

It is the cleaning of the boards from any dirt.

If you have difficulty choosing bleach, then it is best to use a special stain.

After the bleaching process is completed and the lining becomes a clean sheet, you can proceed to the second stage - priming. The third stage is paint application.

Whitening tools needed:

Roller
Brushes
Stain (bleach)
Solvent
Gloves
Eye protection goggles

We paint according to the rules

If the wooden surface has already been painted several times, then before applying a fresh coat of varnish, it is necessary to assess the quality.

If it is still good, then you can wipe it with a 2% soda solution.

To prepare such a solution, you need 10 liters of heated water and 300 grams of soda.

After processing with a soda solution, the work surface should be putty and treated with linseed oil. After such a procedure, all wooden surfaces in the house will be significantly transformed.

If the painting of the lining inside the house occurs for the first time, professionals advise adhering to a certain technology in this matter in order to avoid smudges and irregularities.

Paints should be applied with bristle tips. It is very important that it be subtle. Otherwise, a large amount of paint may become unusable. So that the pile does not leave a mark on the treated walls and ceiling, before painting, it is better to treat them with soapy water.

Be especially careful when applying the final coat. To ensure an even coating, the application protective composition it is best to start at the top. Inaccessible places, for example, frames, plinths, the space near the batteries, are best painted over with a brush that has a diameter of no more than 5 cm.

It is best to start painting the door from the paneled side.

A dry brush will help prevent paint smudges. Upward movements of the brush will remove unnecessary imperfections from the surface.

Cost of work

The price of painting the lining for one square meter is approximately 280 rubles.

One square meter of the lining itself will cost the buyer about 320 rubles. But the cost of boards is significantly influenced by the wood from which they are made, and its grade.

Varnish to process wood can be bought for about 260 rubles per liter.

We hope that this article will help each owner to paint the lining with high quality, as well as to choose the right materials. Good luck with your work.

We paint the lining in the country: types of coatings, interesting ideas, technology

The interior decoration of a country house must be durable, safe and durable. And if in winter it is empty and not heated, then it is also moisture resistant, since the risk of condensation in this case is very high. Not every material can cope with such tasks, however, if you correctly process and decorate the lining from natural wood, it will last for decades.

Depending on how to paint the lining inside the house in the country, it will have a different appearance: Retains the natural pattern and tone, or gains a new one. And protective compounds for wood impregnation improve its performance.

Lining in the design of a country house

Why handle and paint the lining

Any wood material must be coated with protective compounds. Without them, the finish will quickly lose its appearance and become unusable. Paints, varnishes and impregnations have several functions:

Improve the appearance of the front surface of the lining;
Prevents natural darkening of wood;
Protect against mold, mildew and rot;
Reduces resin release from conifers;
Improves water-repellent properties, thereby preventing swelling and deformation;
Reduces the ability to ignite and spread fire.

Coverings different types solve one or more problems. Therefore, for the best protection, you have to choose several formulations at once. How to paint the lining inside the house depends on what functions are assigned to the coating and what kind of finish you would like to get in the end.

Types of compositions for lining

All means for wood processing are conventionally divided into protective and decorative. Some of them need to be combined, others can be used independently. Ideally, the initial processing should be carried out before the installation of the wooden lining, so the products will be protected from unfavorable factors from all sides. If the cladding is already installed and coated, it will need to be removed or sanded.

Note! Euro lining, if it is made according to the standard, is already covered with protective or protective and decorative compounds.

Protective equipment

The primary tasks of these compositions are to protect the tree from pests, mold, fungus, moisture, temperature changes and extend the service life of the lining and topcoat.

Coating the lining with a protective compound before installation

Common products for treating wood surfaces:

Primer. Popular basis for decorative finishing... It improves adhesion, prevents moisture absorption and resin release, fills pores and hides small irregularities. Compositions with an antiseptic additive are produced, they protect the tree from mold and fungus.
Oil-wax. Creates a dense film surface that perfectly repels water. Such processing is necessary for a room with high humidity.
Linseed oil. Deeply impregnates wood, hardens over time. Protects from moisture and gives the lining a pronounced structure.
Drying oil. Once a popular treatment tool. Today it is being replaced by more advanced formulations. Improves the hydrophobicity of the wood, but the coating quickly changes color and sticks.
Bleach. The material is more often used locally, where there are defects such as blue spots, natural darkening.
Antiseptics. Protects the surface from pests, mildew and mildew. They are also used on the affected areas of the finish.
Fire retardants. Reduces the ability of wood to ignite and spread fire.

Oil-wax and linseed oil do not require additional processing, since they give the surface a pronounced pattern, and the color can be tinted. It is also permissible not to paint the drying oil, but it will have to be updated often. Primers and antiseptics are used as a base for finishing.

Lining covered with linseed oil

Decorative coatings

It is necessary to select these compositions taking into account the state of the finish. There are means that preserve and emphasize natural view wood, make annual rings more pronounced, give a shade. Others, on the contrary, hide the drawing under a dense color layer. The first ones should be used if the lining has no defects (Extra, A and AB grades) and old paint... Second, for products with multiple damages (grades B and C) and coatings that cannot be removed.

Transparent compositions for finishing wooden lining: varnishes, stain, some paints. Opaque: acrylic and oil paint, water-based paint.

Lucky

For interior work, acrylic, alkyd and water-based varnishes are most suitable. They completely preserve the natural look of wood. You can add pigment to the composition, which will give the lining a shade. The varnished surface has a glossy or matte texture. Additionally, they protect the finish from moisture, discoloration and minor mechanical damage. May contain antiseptic additives.

Lacquer coating for lining

Decorative glaze

It gives the wood a pronounced structure and any color. It does not form a film on the surface, but penetrates deeply. The material is transparent, so the lining under it should be free of significant defects. In addition to decorative, it has a protective function.

Decorative glaze shade options

Stain

Has almost the same effect as decorative glaze... Colors wood in a rich brown color different shades... Stain is often used for artificial aging of the lining. It is important to take into account that it does not sufficiently protect against moisture.

Stain shades

Acrylic water-based translucent paint

Forms a thin layer on the surface of the wood, through which the texture and natural shade of wood are visible. Such paints hide minor defects in the finish.

Translucent paint on the lining

Oil paint

Dense opaque coating. Forms a film on the surface. It can be of any shade. Retains color and integrity for a long time. This lining paint needs to be renewed approximately every 5 years. Has a pungent odor.

Coating the lining with oil paint

Acrylic paint

More durable opaque coating than oil paint. Virtually odorless, dries in a short time. Can create matte and glossy finishes. Its only drawback is its high cost.

Matt acrylic paint finish

Water-based

Odorless paints, dry quickly. Forms a matte or semi-matte texture. Suitable for dry rooms only.

Water-based paint for decorating a country house

The video shows an example of a competent combination of protective and decorative coatings for lining, applied at home, without the use of special tools.

A wide selection of coatings allows you to choose absolutely any color and texture for the lining. In the conditions of a country house, it is better to give preference to the most persistent and unpretentious compositions that do not have to be updated frequently.

If the panels have a lot of defects or an old coating, then you cannot do without a dense, opaque paint. Improve appearance base surface possible by removing the top layer of wood, but this is too laborious and time-consuming process.

An unusual combination of shades of paint for lining

The colors and shades of the lining can be combined in the decoration of one room. This technique allows you to divide a spacious room into zones. Decorate or diversify the design, highlight accents.

Color accents in clapboard decoration

Some visual effects can be achieved through the color of the finish. Light shades expand the space, dark ones, on the contrary, make it smaller. A white ceiling looks taller than a brown one.

The color scheme for the lining can match the palette of shades used in the interior or contrast.

Harmonious combination color palette textiles and walls

Lining processing technology

The protection and painting of the lining is carried out in several stages. The first is preparation. If the finish is new, then before covering the lining, it is enough to clean it from dust with a solution of 5 liters of water and 150 gr. soda. After drying, the first coat can be applied.

If old coatings are present, sanding with a pumice stone or sandpaper will be required. Better to do it grinder... The purpose of this procedure is to create a rough texture that easily adheres to the coatings.

Cleaning walls from old paint with a grinder

If dense paints are applied to the lining, then they can be cleaned mechanically (with a building hairdryer and a spatula, a grinder) or with special chemical solutions. Both methods do not guarantee perfect results, but it is worth trying. This option is better than painting the clapboard inside the house right on top of the old finish.

The coating can be left on, but then it should be degreased. It is imperative to remove areas with sprinkling paint, air pockets and sand to smoothness.

If there are serious defects, such as knots that have fallen out, the hole must be putty and cleaned to a smooth finish.

Application of protection

If the coating could not be applied to an unidentified lining, then you should carefully coat the joints in order to process as large an area as possible. The composition must be applied in a thin and even layer. To do this, you can use both a brush and roller, as well as power tools. If the protection is applied in several layers, then it is important to dry each of them thoroughly before painting the lining with the following composition.

Dyeing

The method of applying the topcoat depends on its type. General rules work performance:

Use two brushes (wide for the main part, narrow for joints) or a spray gun;
Painting starts from the top so that random drops do not spoil the already finished surface;
Pass one section at a time, in a continuous line;
Some varnishes and paints are applied in two or three layers, each of them must dry naturally within a few days;
It is better to make several thin ones than one thick layer;
Only the painted finish must not be exposed to UV rays and sharp drops temperature.

V hard-to-reach places for staining, you can use a foam sponge. It is best to apply the composition over the entire area in a short time. If you need to take a break, then the joint must be placed in an inconspicuous area.

Paint application with a spray gun

For interior decoration of a country house, lining is one of best options... It does not require complex maintenance, and it is enough to restore the surface once every 7-10 years (depending on the type of coating). If you process it according to all the rules and taking into account the peculiarities of operation, the material will last at least 25 years.

It is the cleaning of the boards from any dirt.

If you have difficulty choosing bleach, then it is best to use a special stain.

After the bleaching process is completed and the lining becomes a clean sheet, you can proceed to the second stage - priming. The third stage is paint application.

Whitening tools needed:

Roller
Brushes
Stain (bleach)
Solvent
Gloves
Eye protection goggles

We paint according to the rules

If the wooden surface has already been painted several times, then before applying a fresh coat of varnish, it is necessary to assess the quality.

If it is still good, then you can wipe it with a 2% soda solution.

To prepare such a solution, you need 10 liters of heated water and 300 grams of soda.

After processing with a soda solution, the work surface should be putty and treated with linseed oil. After such a procedure, all wooden surfaces in the house will be significantly transformed.

If the painting of the lining inside the house occurs for the first time, professionals advise adhering to a certain technology in this matter in order to avoid smudges and irregularities.

Paints should be applied with bristle tips. It is very important that it be subtle. Otherwise, a large amount of paint may become unusable. So that the pile does not leave a mark on the treated walls and ceiling, before painting, it is better to treat them with soapy water.

Be especially careful when applying the final coat. For an even finish, it is best to start applying the protective compound from the top. Inaccessible places, for example, frames, plinths, the space near the batteries, are best painted over with a brush that has a diameter of no more than 5 cm.

It is best to start painting the door from the paneled side.

A dry brush will help prevent paint smudges. Upward movements of the brush will remove unnecessary imperfections from the surface.

Cost of work

The price of painting the lining for one square meter is approximately 280 rubles.

One square meter of the lining itself will cost the buyer about 320 rubles. But the cost of boards is significantly influenced by the wood from which they are made, and its grade.

Varnish to process wood can be bought for about 260 rubles per liter.

We hope that this article will help each owner to paint the lining with high quality, as well as to choose the right materials. Good luck with your work.

Means for covering the lining inside the house

One of the popular options for finishing the surfaces of a wooden house or summer cottage is sheathing with thin boards, known as lining. As a result, rooms are given a cozy feel that allows you to relax in a healthy, environmentally friendly environment.

Why use impregnation?

Some owners have doubts about the need to impregnate wood lining inside a suburban building. If the boards are not covered, changes will be noticeable on them after a while. With poor ventilation, blue will appear on the lining; as a result of intense sunlight, it can turn dark gray.

Plaque gray from the sun can be removed by mechanical grinding of the lining, but the positive effect will not last long. It is more advisable to carry out the processing immediately after finishing the finishing, so that later there will be no problems.

In addition, the coating transforms the wood, makes the interior special. The lining, covered with a waterproof impregnation, can last longer even in an irregularly heated, damp room.

Types of compositions

How to cover the lining inside the house is an easily resolvable question, because there are many products on sale for different climatic zones and types of buildings.

Composite impregnations are designed to perform several functions, the main of which are the following:

lower flammability,
protection against germs,
improvement of appearance,
increased mechanical strength.

There are products designed primarily to protect the lining, and compositions created for a decorative effect. Many drugs perform several functions equally successfully.

What is the best way to process?

There are a large number of products on the market for processing wood materials. Information about the most popular drugs will help potential buyers to make purchasing decisions easier.

Fire retardants

The lining located inside the house next to heating devices must be protected from possible ignition. For this purpose, fire retardant impregnations are used, which are not easy to apply on their own.

Antiseptics

Stains

Special liquids based on water, alcohol or organic solvents that penetrate deep into the wood, create a specific color or shade, are called stains. The term has a foreign synonym - stain. The solutions do not protect, but only tint the wood, although there are special types of expensive wood stains with a pronounced protective effect.

Note! In any case, after applying the stain on top of the lining inside the dacha, it must be varnished. Otherwise, the tree will not retain its original appearance.

Lucky

If you add color to the solutions, you get a colored product with the desired shade. Outside, such a composition will not last long, therefore it is not recommended for outdoor use. Water based varnishes create a vapor barrier to prevent contamination of open pores.

Note! In some modifications of the aqualak, there are additives of antimicrobial action, which significantly improves the safety of the lining inside the house.

In other compositions, substances are introduced that level the effect of UV rays. It makes sense to use such formulations to cover walls that are illuminated by the sun during most of the day.

Paints

To cover the lining inside the cottage, a huge group of various paints for wood can be used.

The "veteran" of the market is oil paints of all colors and shades, which stay on a dry surface for more than 7 years. After the expiration date, the paint layer may discolor and flake off, then the painting will have to be repeated. Pre-treatment of the base with linseed oil improves the fixing of pigments on wood. Drying vegetable oils cover all the pores with a polymer film, which impairs vapor permeability, but improves the quality of the coating.

Note! Oil paints are the cheapest material for covering the lining, which has drawbacks.

Oils and waxes

In addition to drying oil, which is made from drying oils, other oil compositions that are well absorbed by wood are used to cover the lining inside the dacha. They form a matte or shiny surface when gently rubbed in and then polished. Waxes have a similar chemical structure, the difference lies in the replacement of ester glycerol with a higher monohydric alcohol.

Waxes are very durable, form a shiny, even surface when properly distributed and applied to the lining. Wax coatings can last for decades if they are not under heavy mechanical stress. Glaze wax is sold ready-to-use. Hard waxes must be softened by melting in a water bath before application. To distribute the wax evenly, the lining must be primed first.

A good result will be obtained if the boards are coated with a mixture of wax and oils that combine the advantages of both components.

Features of applying impregnations

There are several types of lining, they differ in the number and shape of joints on the resulting surface. Depending on this, it will take a different amount of effort to prepare it.

In any case, before you cover the lining with any means, you must carefully look at all the boards. In the presence of dark spots, local bleaching is performed. Then the entire surface can be lightly rinsed with a diluted soda solution, wait until the water has completely evaporated. Only then can the tree be treated with soil and the basic composition, or immediately by impregnation.

Cracks are covered with putties for wood, everything is thoroughly cleaned with sandpaper.

For a more effective fixing of the decorative layer, the wood is subjected to a primer. It is necessary to distribute the primer very carefully in the seams. To apply primer over the main part of the area, you can use a spray gun; in the joints it is better to prime with a brush.

The better to process the lining inside the room

How to process the lining inside the house - this question worries many who use this product to decorate various rooms. Of course, the material can be left in its original form, but then it must be borne in mind that the service life of the coating will be only 5-6 years. Such a prospect does not seem entirely appropriate.

Why is this needed?

It is necessary to process the material in order to increase its operational properties and maintain an attractive appearance (to enhance the visual impression). It should be noted that working with clapboard consists of several stages, each of which is important.

So, the processing of the lining is necessary to improve the following characteristics:

Resistant to fire. This characteristic allows you to increase the duration of the flame spread over the surface, the ignition time or completely prevent the occurrence of a fire.
Protection of the product from mold and mildew, which lead to destruction. Especially this indicator should be increased in places of high humidity.
Increased resistance to mechanical damage. This property is necessary for those areas that are constantly exposed to impact.
UV immunity. Reduces color fading and drying to a minimum.

The processing of the lining allows you to extend the life of the material

The decorative factor should be noted. It consists in the fact that a substance is applied to the surface of the material that improves its decorative characteristics. Moreover, the surface can remain the same as it was originally, or completely transform.

Various types of treatment formulations

The modern market for building and finishing materials offers wide choose different compositions that can be used for this type of work. The processing of the lining inside the house is carried out independently, without the use of special equipment.

The processing of the lining must be carried out with special compounds.

On a note! To receive good result you need to purchase products that have the necessary certificates, and are also produced by trusted manufacturers. The fact is that there are many fakes on the market that are not only useless, but also harmful to the human body.

Antiseptic solutions

Such substances are used in order to protect wood from the emergence of living organisms (mold, fungi, insects and even mice). The processing of the material with this drug is carried out before facing, due to the fact that it must be applied to the entire surface of the product. This procedure is especially indispensable when it is planned to use the lining on objects with high level humidity.

The application of an antiseptic helps to protect the wood from mold, microbes and mildew

It should be borne in mind that this solution performs exclusively protective functions. Therefore, it is applied before using the decorative components. When choosing antiseptics, pay attention to the place of application. The label must indicate that the product is intended for indoor use.

The work is carried out as follows:

Each fragment is processed separately. Surface treatment on only one side will not bring the desired effect.
A brush and a roller are used as tools.
The antiseptic is applied to the entire surface in a thin and even layer. It is advisable to handle all areas - notches, corners.
Each element is left for a while - until it dries completely. It is necessary to avoid that the material comes into contact with each other during drying.

Work on the treatment of the lining with an antiseptic must be done separately with each element

Thus, wood is obtained that will be resistant to various microorganisms that multiply in a humid environment.

Fire retardants

These compounds are necessary in order to reduce the likelihood of fire. To apply this material pretty hard. The impregnation of the lining with fire retardants will be much more effective if it was produced at the enterprise. Although self-application of the substance cannot be ruled out.

The composition is divided into two groups, which differ in the mode of action:

Fire retardants that prevent combustion by releasing non-combustible gases.
Substances that form a protective film on the surface of the product.

Flame retardant impregnation reduces the likelihood of material ignition

It must be understood that these solutions cannot completely protect against the effects of fire. They only increase the time it takes for the treated elements to ignite.

To know! Now there are solutions that combine the actions of an antiseptic and a fire retardant. This is a combined composition with a combination of their positive properties.

Primers

The primer is applied before applying decorative substances to the lining. This is necessary in order to increase the adhesion of materials, as well as to reduce their consumption.

Before applying varnish or paint, the lining must be treated with a primer

The outer parts of the product are processed. It should be borne in mind that priming can be single-layer or two-layer. It depends on whether the treatment was carried out with other compounds, as well as what kind of wood is used.

On a note! Currently, primers combine mass positive qualities... They not only reduce the consumption of subsequent materials, but also serve to protect against mold and mildew.

Stain

Stain is used as an impregnation if later it is planned to use colorless varnish or wax. It evens out the color of the wood and protects it from changes. Currently, this material has one more protective property. It includes the function of an antiseptic.

The stain improves the color of the wood, and is also used as an antiseptic

Before work, you need to decide on the choice of a solution, which can be on a different basis (alcohol, water and oil). The composition is available ready-made or dry. But the method of application is completely the same.

Wax

The main task of wax is to protect the surface from damage, as well as to eliminate the likelihood of the appearance of poisonous vapors. The last factor applies to cases when the lining is used for cladding saunas and baths. That is, it is necessary to prevent the release of toxic substances when exposed to high temperatures.

Waxing must be done with a soft cloth

Can't be ruled out cleanly decorative effect... The treated surface acquires a deep and even color.

The work is carried out according to the following principle:

A certain amount of material is applied to the surface.
Rub it with a soft cloth until it is completely penetrated.
Several coats should be applied.

Some manufacturers indicate additional conditions that are necessary for the application of wax.

Varnish

Varnish is needed to give the surface beautiful view and protect it from damage. The inner perimeter of the premises is best treated with water-based acrylic compounds. This solution is transparent and translucent. If required, it can be colored by adding color.

Coating with varnish allows you to give the lining a more effective look and protect it from damage

Looks very nice next technology application:

Initially, the first layer is laid - a completely transparent composition.
The second layer is a translucent solution. It forms an interesting shade.

This principle allows you to preserve the natural texture of the wood.

Paints can also be used, but they are rarely used, since they completely hide the natural surface of the material.

Wooden lining has become very popular in our time, especially when it comes to baths or saunas. It is even used to decorate apartments and houses, a corridor. The entrance hall, finished with clapboard, has a very good look. You can find out the dimensions of the lining by clicking on the link. But before you start buying this material, you should find out that in addition to finishing the room with clapboard, it needs to be processed in the future. This will give the lining an aesthetic appearance and extend its service life. There are several processing methods, in this article we will introduce a few.

Processing lining in the bath

Why do you need to process the lining?

The lining made of natural wood needs further processing, the reasons are obvious. If, for example, lining is used for exterior decoration, atmospheric factors will affect its condition - these are temperature, humidity, wind, direct Sun rays... All this can lead to her deplorable state:

Appearance deteriorates
Mold and rot develops
Color changes
Material deformation occurs

Not even all the changes that can occur to your clapboard in a year are listed here, without additional processing. Of course, if the lining is used for interior cladding of the room, the environment here is softer and therefore changes will occur more slowly.

Lining preparation

Before proceeding with the direct processing of the lining, you need to prepare it for this procedure. The first step is to go through with fine sandpaper to remove all irregularities and roughness from the tree. After that, you need to clean the lining of dust, a small brush is suitable for this. When all this is done, you can proceed to the direct processing of wood.

Stain application

If you are going to cover the lining with clear varnish or wax, you first need to use a stain. It will allow not only to even out the color of the wood, but also to preserve it for many years. Modern materials allow not only to change the color of the wood, but also are excellent antiseptics that will protect wood from mold and moisture penetration.

There are water-based, alcohol-based and oil-based options on sale. They come in the form of a powder that should dissolve or ready-made - in the form of a liquid. You will end up with a liquid that is brushed onto the wood.

Waxing the lining

If the lining will be used in the steam room of a bath, then here you cannot do without waxing it. After all, when high temperatures and high humidity there is a risk of poisoning if the wrong materials are used. And wax is a natural material that does not carry any troubles.

The wax is applied with a cloth, a small amount is applied in the direction of the grain. The procedure is repeated several times. After polishing, the lining will acquire a deep, even color.

There are various impregnations with wax on sale, they are also well suited for processing lining. You can learn the details of their application from the product instructions.

Lining the lining.

Varnish is already a proven means for protecting wood from an aggressive external environment. Today there are many different products of this type. If previously only transparent varnish was used, today you can purchase varnish with different shades.

You need to use waterproof varnish, buy not the cheapest - the most the best option this is the middle price category. It is applied in several layers, two or more. A period of time is needed between each layer that will allow it to dry. Depending on the type of varnish, drying can take from 8 hours or more.

It is advisable to sand the lower layers of varnish with fine sandpaper to remove the raised pile of wood from the surface.

Processing lining inside the house - instructions

A huge number of people all over the world are engaged in decorating their homes, and of course they prefer beautiful and natural material- wooden lining. This is both environmentally friendly, and you will be surrounded by natural beauty, and such material not only creates beautiful impressions, it also affects a favorable microclimate in the room.

But in order for this natural material to serve for a long time, you need to take care of it, and most importantly, you need to do it right. You can't take it and paint it ordinary paint- you spoil all the attractiveness, the material will stop breathing, and after a short time the paint will begin to crumble.

Inside the house includes a complete set of works based on four stages:

Preparation.
Primer.
Protection.
Decorative staining

Preparing the lining for painting

If you are using eurolining, then you can skip this step, because European manufacturers act according to special standards, which imply the obligatory primary treatment of decorative wood panels with protective compounds.

For those who bought a standard domestically produced lining or will install not new, and already processed lining, this stage is mandatory.

Preparing a new lining

Preparing a new lining made of wood, which was purchased by you in one of the stores building materials, includes the following activities:

A batch of lining, as a rule, allows for re-grading of up to 10%, which means that a material of the first grade may contain a small amount of second-rate board. In order not to violate the integral appearance of the surface, the material must be carefully examined and sorted.
The lining that you purchased before installation must be perfectly dry. She should also lie down in the room where the installation will be carried out for 2-3 days so that her temperature evens out.
Elimination of defects. Defects on the surface of the lining include irregularities, blue or white spots, knots. You don't need to touch a part of the defective lining, because in the process of work you will need a short piece of material - for finishing over the doors and windows, and you will have something to cut from. But before starting the installation, the front surfaces of the material must be cleaned of stains using bleaching.

Important!!! A good bleach is recommended for this kind of work. Grease stains can be removed by demineralization, for this they are wiped with a 25% acetone solution. By using sandpaper or a metal brush, you can remove small protrusions.

Unfortunately, painting a wooden lining is not a process that can be performed only once during the entire period of its life. This procedure must be repeated periodically.

Before painting or varnishing the lining, it is imperative to pre-treat its surface.

As a rule, re-painting the lining is necessary in the following cases:

the bottom layer of paint is peeling;
the lining has lost color;
paint or varnish has lost its luster;
a significant defect has appeared on the surface, for example, fungal damage;
the existing color of the lining is not suitable for the new interior of the house.

How to clean the lining from varnish, paint and dirt?
There are two ways to remove old varnish or paint from the lining surface:

Chemically... Includes the use of a variety of synthetic fluids and forms - removers and emollients to help the paint flake off the surface. Please be aware that chemical method pretty aggressive. After removing the top layer, the lining should be washed with water or wiped with white spirit.

Important!!! To carry out activities using these means, the area must be well ventilated and you must have personal protection.

Mechanical... In this case upper layer removed with a metal brush, scraper or construction hair dryer and a spatula. To completely remove paint from wood, you can treat the surface with a soda solution. The big disadvantage of this method is the possibility of damaging the smooth surface with a brush or scraper.

Important!!! If you are unable to decide which surface cleaning method is preferable, take a look at these tips:

The mechanical method of cleaning the lining is the most suitable for removing oil paint.
If you plan to cover it with a transparent varnish after cleaning the surface, then it is more advantageous to prefer the mechanical method, because the removers can bleach the lining unevenly.

If there are deep defects in some places in the material, they must be repaired with wood putties.

To give a unified structure wood flooring the primer is applied with a gun or brush.

If primer is applied before painting, it will give wooden lining several undeniable advantages:

will improve "adhesion" to the future surface layer - varnish or paint;
protect the tree from moisture penetration;
will close the pores, allowing you to apply the topcoat more evenly;
reduce consumption decorative coating- paint or varnish.

Important!!! Certain types of wood, such as pine or spruce, can give off resin for a long time. To avoid this, the lining must be treated with a special primer that will close the wood pores.

Types of primers for lining
The variety of primers depends on the composition. On modern market building materials you can find the following types of primer:

Alkyd... This coating is suitable for both outdoor and internal use... The material is adapted for different types of trees, so the choice here is very diverse.
Acrylic... This composition is reliable protection from all damage except rot and rust. Such a primer is suitable for use when carrying out internal repair work.
Polystyrene primers... Due to their high toxicity, they are only suitable for outdoor work.
Primer with PVA glue. This option is well-deservedly popular, a solution of PVA glue, prepared in a ratio of 10 drops of glue per 100 ml of water, it is applied in two layers. This is necessary in order to avoid the appearance of unprimed areas, which will be visible only after complete drying.

Important!!! Disadvantages of the latter method: a whitish coating may appear on a wooden lining, such whiteness is not visible on raw wood, but on a tinted surface, this is very noticeable. It also partially hides the structure of the wood.

Gelatin primer. As a primer, some recommend using edible gelatin. Gelatin is soaked in cold water in a ratio of 1 part of gelatin to 2 parts of water, then heated in a water bath until the granules are completely dissolved. The composition is cooled to a slight thickening and the lining is treated with it in 2-3 layers.

Important!!! The best chemical industrial primers for the restoration of lining are deservedly considered compositions from the following manufacturers:

Tikkurila;

Belinka;

Lacra;

Pinotex.

In order to protect the surface from scratches and other damage, it must be covered with special chemical compositions... These products are designed to protect wood from moisture, rot, fungal infections, insect pests and UV rays.

Methods and means for wood protection

Specificity of such protective equipment lies in the fact that they become invisible when dry and penetrate deeply into the structure of the tree. The use of such forms is a very important step in protecting the lining. Euro lining manufacturers do this even during pre-sale preparation.

Important!!! Protection and processing of the lining, it is better to do it on both sides. Special attention should be paid to the ends of the material. This is due to the fact that after installation, the end side is not painted over.

You can choose these solutions to protect the material inside the house:

Fire retardants... Compounds that are the basis aqueous solutions salts. They are designed to protect wood products from fire.

Important!!! The decorative elements made of wood used by you must definitely increase the fire resistance.

Antiseptics... it chemical compounds, which have an active antifungal effect. They are designed to protect the lining from the biological activity of various fungi and pests.

Important!!! Before installation, the lining must be treated with an antiseptic. This is due to the fact that the reverse side of the strip, ends, locks also need to be processed with this tool.

Choice of topcoat

Natural resins, oils and waxes

V last years people are becoming more and more inclined to choose natural or so-called natural material... However, you should be aware that manufacturers and sellers with this weakness can simply lure their customers. The reason is the very vague line between "natural" and "synthetic" coatings: natural is supposed to be made from renewable raw materials and only minor chemical changes in these raw materials are allowed. This product must also be biodegradable, and its manufacture, use and disposal must not adversely affect the environment.

In general, it can be said that buyers are mistaken when they believe that natural substances are always completely harmless. And among them there are those that are toxic and dangerous to human health. Many of the substances that plants contain are deadly.

Of course, such dangerous compounds do not exist in natural coatings, but you should be aware that "natural" or "bio" alone does not provide complete safety for your health. It should also be emphasized that ordinary natural finishes, in comparison with synthetic paints and varnishes, have lower physical and chemical properties, and they often need to be restored.

Natural oils that are most commonly used for surface treatments are:

linseed;
tung;
castor;
hydrogenated;
hemp;

Drying time for natural, untreated linseed oil is very long - more than a week, so it is not convenient for practical use. Thus, a special varnish is made from it, containing heat-treated linseed oil, and desiccants are added to it to accelerate curing.

The most famous natural wax is beeswax but it is rather bland for practical use. Therefore, surface waxes always include so-called carnauba wax, which increases the final hardness.

Paraffin is a synthetic product of the distillation of oil, it is also very similar in its physical properties to wax - but naturally it is not a natural product.

Natural wood coatings often include a variety of natural gums as one of the ingredients, such as shellac, sandarak, or rosin.

Nitrocellulose coatings

The binder for these coatings is nitrocellulose obtained by nitration of natural polymers - cellulose. Thanks to the quality of nitrocellulose (NC) varnishes, we can include them in our list of natural materials.

NC varnishes contain acetone, ethyl acetate, butyl acetate, ethanol, aromatic alcohols and the like as solvents and thinners. Rejection physically occurs simultaneously with the volatilization of these substances. Nitrocellulose varnishes - when used on a treated surface - are often superior to more modern varnishes, but they also have a major disadvantage: weaker resistance to certain solvents - acetone, for example.

In its manufacture, a high content of volatile organic solvents is important and, as a result, an inadequate impact on the environment.

Polyester varnishes

Polyester (PE) varnishes were popular in the old days, because their main feature is strength - (hardness, elasticity), the ability to reach glossy surfaces ... But today they are little used, as they contain styrenes, which are very harmful. Yes, and they are not attached to a wooden surface very well, especially on small parts.

Polyurethane varnishes

Polyurethane varnishes are the products from which water-based varnishes are made. We can find them on sale in various forms - one-component and most often two-component. these varnishes are durable, with good elasticity, good adhesion, durability, high water resistance and chemical resistance.

Unfortunately, many polyurethane varnishes can change color when exposed to ultraviolet light. As for using them for floor coverings or furniture then this is a great material.

One-part polyurethane varnishes contain 20 to 30 percent dry matter and are actually a melting of the PU prepolymer, they become solid by absorbing moisture from the air, which allows them to chemically react with carbon dioxide.

One-component PU varnishes are versatile and easy to use and must be applied in a thin layer (80 to 100 g per square meter), otherwise the surface quality will be poor.

Acidic polycondensation varnishes

These varnishes are also called "acid resistant varnishes" or "acid resistant varnishes" in everyday speech. They contain formaldehyde resins as binders. Rejection is physico-chemical, that is, it refers to the disappearance of volatiles and the polycondensation reaction.

The catalyst that speeds up the reaction is the organic acid to which this coating group is applied. By themselves, these varnishes are hard and brittle, so alkyd and other resins are often added to them.

Polyacrylic varnishes

The binder is polyacrylates, from which water-based varnish is made. In combination with polyurethane binders, they are also very popular as indoor treatments.

There are many different derivatives of this material, from physically drying, which are thermoplastic to those modified compositions intended to be cured by ultraviolet rays.

Alkyd varnishes

Alkyd resins are rarely used indoors as they are most commonly applied to metals. However, alkyd binders are increasingly being used to protect wood outdoors and clear glazing based on organic solvents.
