Colorless varnish for lining. How to cover the lining inside the house? The best way to treat lining indoors

One of the popular surface finishing options wooden house or dachas - cladding with thin planks, known as lining. The result is a cozy feel for the rooms, allowing you to relax in a healthy, environmentally friendly environment.

Impregnation for lining inside the house, which can be purchased in specialized stores and applied in accordance with the manufacturers' instructions, helps ensure that the interior remains unchanged for a long time. There are other means that can be used to coat wood.

Why use impregnation?

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

The blueness is explained by the action of microorganisms, which can be gotten rid of with the help of active oxidizing agents, such as chlorine. The procedure is not very easy to perform and is accompanied by the release of an unpleasant odor.

Plaque that has turned gray from the sun can be removed by mechanical grinding of the lining, but positive effect that won't last long. It is more advisable to carry out the treatment immediately after finishing, so as not to have problems later.

In addition, the coating transforms the wood and makes the interior special. Lining coated with waterproof impregnation can last longer even in an irregularly heated, damp room.

Types of compositions

How to cover the lining inside a house is an easily resolved 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 ones of which are the following:

decreased flammability,
protection against microbes,
improvement of appearance,
increasing mechanical strength.

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

What is the best way to process it?

Available for sale a large number of means for processing wood materials. Information about the most popular drugs will help potential buyers make it easier to choose a purchase.

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 your own.

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

Antiseptics

A strong risk factor for wood damage is microbiological exposure. They get rid of it with the help of antiseptics. Antimicrobial solutions that can be used to impregnate wood cope with biological contaminants and prevent the emergence of new areas of mold and rot. Antiseptics have a pungent odor that does not disappear for a long time, and you need to pay attention to this when purchasing, having studied reviews of the product.

Preparations that cost more than conventional disinfectants can not only protect against microorganisms, but also at the same time improve the aesthetic impression and increase the ability to repel water molecules.

Stains

Special liquids based on water, alcohol or organic solvents that penetrate deep into the wood create specific color or shade, is called . The term has a foreign synonym – beitz. Solutions do not protect, but only tint the wood, although they exist special types expensive stains with a pronounced protective effect.

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

Sometimes wood planks have dark spots, the appearance of which remains a mystery. You can treat such areas with bleach, carefully selecting the concentration and exposure time. You can practice on lining waste, see how many tones the wood base is lightened by, and draw the appropriate conclusions.

Lucky

Varnishes have a good protective effect on the lining inside a 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 and create a biological barrier on it.

Due to the minimal allergenicity indoors, it makes sense to use aqualak. It takes longer to dry than solutions in organic liquids, but is safer for health. With aqualas you can create a completely or slightly matte, as well as a glossy surface.

If you add color to the solutions, you get a colored product with the desired shade. This composition will not last long on the outside, so it is not recommended for outdoor use. Water-based varnishes create a barrier to steam penetration, eliminating contamination of open pores.

Note! Some modifications of aqualak contain antimicrobial additives, which significantly improves the safety of the lining inside the house.

Other compositions contain substances that neutralize the effects of UV rays. It makes sense to use such compositions on walls that are illuminated by the sun for most of the day.

Alkyd varnish solutions are extremely durable; after drying, the coating can last for 10 years. Usually, inside a wooden house or cottage, it is recommended to cover the floors with such compounds. Those who like constant color schemes for rooms can apply alkyd varnishes to the walls. If the desire to change the interior arises earlier, you can spread a different color of varnish on top.

Paints

A huge group of different wood paints can be used to cover the lining inside the cottage.

The “veterans” of the market are oil paints of all colors and shades, which last on a dry surface for more than 7 years. After the expiration date, the paint layer may become discolored and peel off, in which case the painting will have to be repeated. Pre-treatment of the base with drying oil improves the fixation of pigments on wood. Drying out vegetable oils cover all 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 lining, which has disadvantages.

Due to clogging of the natural pores of wood, the indoor microclimate worsens. When painting, active evaporation of a solvent occurs bad smell. Vapors from organic liquids are harmful to health, so painting can only be done in summer with windows and doors open.

Acrylate paints are also made on a strong-smelling base; painting must be done carefully, with careful ventilation of the rooms. Acrylate paint is applied faster and easier than oil-based paints and forms a resilient, elastic coating that is long-lasting and durable. Walls inside the dacha painted with acrylics tolerate well winter cold 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 the glycerol ester with a higher monohydric alcohol.

Waxes are very durable and form a shiny flat surface when properly distributed and applied to the lining. Wax coatings can last for decades in cases where there are no large mechanical loads. Wax glaze is sold in a ready-to-use condition. Hard waxes must be softened by melting in a water bath before application. To ensure that the wax is distributed evenly, the lining should be pre-primed.

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

Features of applying impregnation

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

In any case, before covering the lining with any means, you need to carefully examine all the boards. In the presence of dark spots carry out local clarification with bleach. Then the entire surface can be lightly washed with a diluted soda solution and wait until the water has completely evaporated. Only after this can the wood be treated with primer and the base compound or immediately with impregnation.

The cracks are covered with wood putty, everything is thoroughly cleaned with sandpaper.

To more effectively secure the decorative layer, the wood is primed. Very carefully you need to distribute the primer mass in the seams. To apply primer over the main part of the area, you can use a spray gun; at the joints it is better to prime with a brush.

Each product has its own application characteristics, which are necessarily described in the manufacturer’s recommendations. The accompanying documents must be carefully studied and the compositions prepared in accordance with the instructions. All products are applied in several stages; each subsequent stage can be performed only after the surface has dried, and the final layer must be the thinnest. Following these rules will help you get a reliable and beautiful coating.

Lining is a finishing material that looks good in the interior of a wooden house. It is used for both residential and commercial premises. The wood from which it is made needs to be treated with protective agents. And to give an attractive appearance, they apply decorative coating. Naturally, to create beautiful coating you need to choose the right processing products and decorative materials.

Why treat lining and how to choose the right products

Before processing the lining you should find out:

is it necessary to apply a protective coating, or can you do without it;
in which rooms will the treatment be carried out - dry or with high humidity;
whether to apply a decorative coating, tint or leave it natural.

Having decided, you can begin to select the impregnation and material for decorative finishing of the lining in interior spaces. You can leave the lining uncoated, but this option is suitable for people who are satisfied with the fact that the wood darkens over time. Some owners do it on purpose artificial aging using a blowtorch. After this, it not only darkens, but also releases resin, which gives the surface its individuality. It happens that bathhouse owners do not treat the walls because they use cheap lining. It will be more practical for them to change it completely after a few years rather than waste time and money on processing it.

In order to properly process the walls, you should know what functions the impregnation for the lining inside the house should perform. So, the impregnation should:

give good protection from ignition, such qualities are given to wooden products by fire retardants, which reduce its flammability;
protect from moisture, especially during wet areas. To do this, antiseptic agents are applied to the wooden surface;
protect from mechanical damage(chips and scratches);
protect from exposure to ultraviolet rays. Wood treated with agents that increase resistance to ultraviolet radiation changes its color more slowly;
provide bactericidal protection against insects;
give walls beautiful view. You can give the lining the desired shade using tinting. Using varnish, you can make the surface glossy, matte or semi-matte.

To give the tree the necessary properties, several compounds that have the required qualities are usually used.

Types of compositions - fire retardants, stains, varnishes and paints

All compositions for processing lining can be divided into two groups: protective and decorative. The first are designed to extend service life. They protect against moisture, insects, fungus, and mold. The latter give the lining an attractive appearance. The treatment must be updated regularly, as over time the products lose their properties. Processing of lining indoors is carried out with the following compounds.

Fire retardants reduce the flammability of wood. This is especially important for living rooms. If a fire occurs, fire retardants prevent the spread of fire and help extinguish it. They are odorless and therefore harmless to health.

Antiseptic agents protect against the formation of mold and mildew. Stops the spread of existing mold. Over time, the product is washed out and evaporates, so re-treatment is required. There are bio-moisture-proofing agents that not only protect against fungus, mold, and pests, but also give the wood water-repellent qualities and an attractive appearance. They are expensive, but make it possible to refuse treatment with stain, antiseptic and varnish.

The stain performs antiseptic functions, but at the same time gives the wooden surface a tint. The most popular stains are those that impart dark shades. This product does not create a film on the surface, but penetrates into the pores of the material to a small depth. Wood saturated with stain should be varnished, otherwise the surface will look dirty. Drying oil was previously very popular, but recently it has been used less and less. The wood quickly darkens, and after 2-3 years the surface becomes sticky. It is used for utility rooms.

Bleach is designed to remove wooden surfaces dark spots, areas with a blue tint, stripes. There are several types of such products, differing in application and effectiveness. Usually the product is applied to the surface and washed off after a certain time.

Varnishes are used if you want to preserve the naturalness and texture of wood. Acrylic varnishes that are harmless to human health are used indoors. The first layer is applied transparently, without dyes, and coloring pigments are added to the second. Alkyd varnishes are more used for floors, as they have high strength properties. They are applied to walls in places where large mechanical loads are possible. An alternative is wax mixtures that protect the wood and give the surface a semi-matte shine.

Oil paint penetrates deeply into wood, provides good protection from moisture, and is resistant to mechanical damage. Used for decorative finishing. Disadvantages: low vapor permeability, takes a long time to dry, loses color over time. Acrylate paint is in many ways superior to its oil counterpart: it dries quickly, does not fade over time, penetrates well into pores, gives a rich color, and has high vapor barrier qualities. It does not crack if the panels are affected by temperature changes. This paint has one drawback - its high cost.

Technology for applying protective and decorative coatings

At the finishing stage, a novice builder has to master new technologies. You need to nail the lining correctly, know how and with what to process it, and perform decorative finishing. Coating the material with the selected means is carried out in stages. Before processing, prepare the lining.

1. First, it should be cleaned of contamination with a solution. For this purpose in warm water dissolve the soda. Wash the lining with this solution. If there is an old layer of paint, for better adhesion it is advisable to completely remove the previous layer to remove cracks and peeling.
2. Inspect the cleaned lining: remove mold, mildew, and treat darkened spots with bleach. Finally, the panels should be wiped with a clean rag to completely remove dirt and paint residues. If there are damaged panels, they must be replaced.
3. At the next stage, we grind the surface. The operation is performed using pumice or fine-grained sandpaper. To avoid any unsanded areas, divide the entire wall into small areas and process them consistently. Sanding should be done evenly, being careful not to rub in one place and not to apply much force.
4. The final stage of preparing the lining for application of products is priming. Apply a layer of primer to the wall using a brush or spray gun. The seams between the panels must be treated especially carefully. One layer is enough. Sometimes a painting compound is used as a primer.

By yourself or with a brush. For painting, prepare two brushes: narrow and medium - use the narrow brush to paint hard to reach places. In order for the coating to serve for a long time and be durable, you need to apply 2-3 thin layers. The painting procedure is as follows:

mix the paint and pour it into a small container;
dip the brush in paint up to half the bristles;
Before applying, press the brush to the surface and smoothly move it along the panel;
then apply the paint in the same way over the entire surface, without touching the painted areas;
We paint corners and openings with a narrow brush.

You should start applying paint from the top to avoid drips. To eliminate shade differences, apply one coat at a time. If you need to take a break, you should leave your work out of sight. Apply the next layer after the previous one has completely dried. We make the final layer minimum thickness, apply with light, even movements from top to bottom.

The varnish is applied in the same way. If the product is tinted, it should be thoroughly mixed before application and stirred periodically during use. We add less coloring pigment to each subsequent layer, in this case the surface after painting will acquire a deeper and more attractive shine.

Varnish for lining inside the house improves the appearance of the finish and extends its service life. What goals are pursued when creating comfortable living conditions?

Home is a fortress, a place of spiritual rest after a hectic day, a cozy, reliable rear. Comfort and peace can be ensured in the house only by choosing the right finishing materials and creating with your own hands an interior that matches your state of mind. Wood never went out of fashion, it was just that products made from it were improved and external processing improved.

To determine which lining is best for your home, let’s turn to specialists for information.

Interior and exterior decoration of buildings

How and why should rooms be sheathed? If we survey residents of apartment buildings about their desires, many want to live closer to nature, outside the city in their own house, work at home on the Internet remotely, and dig in their garden beds in their free time from the road.

Others will never trade for anything city apartment, but create a special one, cozy atmosphere in the house, as close as possible to nature, using wooden lining for decoration. To make the lining, trees growing both locally and abroad are cut down. Pine, aspen, birch, linden, larch, oak, cedar (see) - a very small list of trees suitable for the production of lining.

What determines the choice of lining

First of all, the choice of lining depends on the room where the surfaces will be sheathed:

In rooms with high humidity, which include a balcony (see), bathroom, kitchen and toilet, it is preferable to use plastic lining(PVC).
The walls in the hallway, bedroom, office, living room must “breathe”, so wooden products are important there. The choice of wood type is also not in the background. Pine in a steam room is nonsense. When heated to high temperature resin begins to be released that can burn the skin.
Plastic lining in the interior country house has the right to life. It has a huge color spectrum, allowing you to get interesting color solutions. It is easy to care for and simply dismantled during repairs, since plastic is subject to mechanical stress and its service life is not very long.
To the benefits wooden lining include high sound insulation, the ability to retain heat, a beneficial effect on human health, long term service due to its high resistance to decay after appropriate processing and painting.

Attention: Only wooden products are divided into classes “Extra”, A, B, C, where “Extra” has the highest cost and quality.

Finishing surfaces with lining is carried out for more than one year; craftsmen recommend not saving on materials and purchasing high-quality cladding panels. This statement especially applies to the bedroom, living room, and office. Even more can be said, if you use coniferous panels of the appropriate quality, the rooms are filled with the pure smell of the forest, giving the atmosphere a constant unity with nature.
Next you need to decide, and in different rooms. The owners have similar goals, and every owner wants to receive both outside and inside:

Sheathing that is resistant to moisture even with direct contact between water and wood.
To the strong influence of ultraviolet radiation.
Resistant finish to mechanical damage.
Processing the lining inside the house should protect the wood from insects that can cause harm. This is especially true for suburban buildings and dachas.
Beach wooden products– fungus and mold, there are also protective agents and compounds against them.

Unfortunately, all these wishes cannot be solved with one tool, because there is no way to connect the components. The instructions and experts offer ways to solve individual problems in order to get a unified picture of the protective properties.

What's interesting on the market

So:

One-component varnishes on water based characterized by low strength and durability, but working with them is much easier.
Two-component varnish It contains a base and a hardener. The video in this article provides data on its use. Most often it is used for eurolining, making its protection much more effective.

Attention: The varnish consumption is determined by the brand and thickness of the applied layer. To process planed products and lining, 1 kg of varnish is required per 17 m², for sawn, untreated wood - 1 kg per 7 m².

Regardless of the type of varnish, it is distinguished by the fact that it does not contain a solvent and you don’t have to think about how to cover the lining in the house so that an environmentally friendly atmosphere remains. Its use guarantees complete safety.
Some may object and speak out in favor of lining without any coating at all. This option also has its positive arguments. What is uncoated lining? It is impossible to say that this is a pitiful sight. Over time, it simply darkens and many are not bothered by this fact; they simply update it after 5-7 years.
An idea of how to treat the lining inside a house is given by simple analysis their purpose.

Drying oil refers to an outdated type of coating used in utility rooms. It can be noted that it copes with protection, but does not stay on the surface for long.
Fire retardants allow you to increase the fire safety of wood, reducing flammability finished products. When choosing a lining, you need to pay attention to this fact of processing specifically in industrial version. It is impossible to obtain the desired effect manually at home due to the inability to provide the required pressure on the surface.
Bactericidal compounds have antibacterial properties and protect wood from rotting processes. When purchasing such mixtures, you need to look for a special note on the packaging “for interior work", meaning water-based.
Water based acrylic varnishes allows you to use them at the final stage of processing. Acrylic varnish performs two functions at once - it protects the wood and decorates it. When there is a desire to preserve the texture of the lining, these are the varnishes that are used, which are applied in two steps. Transparent at first, then varnish is used with a mixture of the desired color.
How to cover the lining inside the house and is it possible to use synthetic varnishes?, because they are more toxic when compared with acrylic ones. It turns out that they are also used, because it turns out very smooth surface with a rich shine, but more often for outdoor use due to toxicity. Toluene and xylene have the ability to concentrate in indoors and have a harmful effect on the health of the occupants of the home.
Instead of varnish, wax-based compositions are ideal for interior work.. It should be noted right away that they are difficult to apply to the surface, but their excellent protection and delightful semi-matte shine are worth all the costs and difficulties. The main thing is that the selected composition is compatible with the finishing coating.

Separately about water-based varnishes

These compounds need to be given a separate section, because they have a number of advantages.

How do they cover the lining inside the house, if not with these mixtures? They do not contain toxic substances or smelly solvents, they are recommended for use in a children's room, and this says a lot.
The water base prevents the treated surface from burning.
The original shade remains unchanged for a long time, when other materials turn yellow under the influence of sunlight.
The color underneath lasts a long time wood paneling.
If you follow the instructions on the packaging, it is easy to use and can be a pleasure to work with.
It does not roll off the surface of the lining due to high-quality adhesion to it, which makes varnishing simple and accessible for beginners.
Large areas can be quickly sprayed, and the water base does not allow the varnish to remain in the equipment, without contaminating it or making it difficult to maintain.
We cannot ignore the disadvantages of water-based acrylic.

High cost of compounds.
Long drying period for layers.
Negative effects of changes in temperature and moisture.
When working in the room, the temperature must be above zero, otherwise the varnish will become unusable due to freezing of the water base.
Despite the fact that very high-quality varnishes (and therefore expensive) can withstand up to 5 cycles of freezing and defrosting, why do these experiments in your own home?

Claim that everything negative properties are fatal in nature and inherent in all varnishes, it is impossible. If you follow the recommendations for their use, these compositions will become perfect choice for wooden products.

Decorative paints for lining

Decorative paints continue the topic of how to cover the lining inside the house and provide reliable protection.

Oil paints quickly penetrate the structure of wood, but dry slowly, losing color saturation over time. They are not recommended for covering all surfaces in a room, as the wood stops “breathing”.
Acrylate paints shine and retain their attractive appearance much longer. oil paints. They surpass them in other indicators as well. For example, significant changes in temperature do not lead to cracking. The high price, which can be attributed to a major drawback of this product, does not stop connoisseurs of beauty and quality.
The best the best option for processing lining - acrylic aqualac. There is no toxicity, no heavy metals, it does not cause allergies in the inhabitants of the house, all these qualities determine its popularity.
From the variety of mixtures and products offered, it is clear that there are many options for treating the lining outside and inside the house. The labeling of the products offered and the place of use will help you avoid making a selection mistake.
The photo shows a decent job, carefully prepared.

The surface is clean and free of contamination.
The surface has been polished. A good result is obtained when wet grinding, when the lining is wetted, processed and dried well.
Coating a wooden panel with a primer reduces varnish consumption.

It is allowed to work with varnish indoors with a brush, roller, or sprayer, following the following recommendations.
Colorless varnish is applied along the wood grain.
Decorating varnish is sprayed, and if there is no sprayer, then a swab is used.

Attention: The tinting varnish must have a uniform shade and structure, so it must be thoroughly mixed.

Any varnish can be diluted with plain water, except drying oil and other organics.
Uniform layers are achieved by applying thin strokes rather than thick ones.

The surfaces will have deep, high-quality processing, if you first go through them with a tinting varnish with a darker shade, and then enhance the impression with a transparent varnish with tinting, but not more than 10%. Each subsequent layer is applied after the previous one has completely dried.

If, after drying, the layer is additionally treated with “null” before covering with the next layer of dye, you will get a surface that can please even a master with its deep and uniform color.

If you decide to cover the walls inside your house with wood, then the question of proper processing of the material should be open to you. Of course, in specialized construction stores The choice of protective materials for wood is very large, but choosing the right product from the offered range can be difficult.

LONG SERVICE LIFE

Rules for selecting protective compounds

When choosing materials suitable for processing lining, you need to answer three questions:

Is it worth covering wood siding at all?
What is the microclimate of the future room (will there be high humidity in it, on the contrary, will the air be dry)
Is decorative coating necessary?

Having solved these problems for yourself, you can safely begin choosing impregnation for materials.

It is worth noting that in this article we are considering impregnation materials suitable exclusively for internal lining. External coating requires a completely different composition.

Lining without coating

Despite the apparent impracticality, this option still contains some advantages. In order to notice them, you need to understand what uncoated lining is.

It turns out that it will simply begin to darken over time. And if this doesn’t bother you, then simply updating it in 5-7 years will be more rational decision, rather than a selection of expensive impregnating compounds.

Nowadays, wood processing with a blowtorch has become popular. As a result, it acquires a dark shade that does not change over time.

Wood after heat treatment

Problems solved by lining coating

If you still decide to coat wooden panels, then you should understand the advantages that it can give us.

Anti-ignition. It is carried out by treating the panels with substances - fire retardants, which reduce the flammability of wood.
Prevents rotting. It is especially important if you use the lining in rooms with high humidity.
Mechanical protection. Of course, wood paneling is less susceptible to chips and scratches than a floor made of the same material, but additional measures precautions won't hurt.
UV protection. The wood will practically not lose its original color.
Decorative function. Using tinting compounds you can add to your panels various shades. If you do not want to change the natural color, you can use a transparent coating, but with a glossy or matte texture.

Most often, several compounds are used to treat wood cladding. This is done due to the fact that it is impossible to combine all the necessary compounds in one product.

COMPOSITIONS FOR PROCESSING LINING.

Impregnations and stains

When choosing a suitable impregnation, you should consider several composition options. And first, you should pay attention to mixtures that penetrate directly into the wood. These are nothing more than impregnations and stains.

Treating wood with an antiseptic using a sprayer

Drying oil– an outdated type of coating, applicable exclusively in utility rooms. Of course, it copes well with protection, but the effect is not long-term.
Protective (protective) compounds– used to give the lining antiseptic and fire properties. Typically, such impregnations are applied to the sheathing on both sides, so the application process must occur before actual installation.

Note! Your formulation must be compatible with the finish you choose.

Antiseptic film coatings are similar to antiseptic ones, but are more suitable for external treatment.

Stains - used as a decorative agent coupled with disinfection.

The most popular types of impregnations on modern market– “Tikkurila”, “Senezh”, etc. Despite the fairly high price, try to choose products only from trusted manufacturers. Their quality and results will not disappoint you!

Varnishes and paints

Usually, after impregnation wooden panels They have a rather unpresentable appearance. And after the processing stage, it’s time to start painting and varnishing your panels.

Varnishes retain color and structure natural wood, but they smooth out their appearance. For interior decoration Water-based varnishes are best. They are non-toxic and apply well.
To protect against fading, choose a coating with UV protection.
Paint for lining is a less popular option, but also has its place in application. Most often, transparent paint is used, which partially preserves the structure of the wood. The most common manufacturers are “Belinka”, “Texturol”, “Senezh”.
Wax paints are the best option. But it carries one significant drawback - cost. The basis of such products is real linseed oil.

Note! To treat the lining of baths and saunas, use specialized compounds. For example, "Supisaunasuoja" or "Evrotex-Sauna".

COATING TECHNOLOGY

If you apply the coating to the lining yourself, then you need to perform actions in a certain sequence:

Carry out initial treatment: dry the sheathing, clean the surface with a scrub brush.
If there are dark spots, bleach the wood (such special means like “Senezh Neo”, “Rime”, etc.)

After the previous procedures, thoroughly rinse the lining and dry it again.
To fill the pores, treat the panels with a primer.
Then treat the wood with antiseptics and fire retardants.
After finishing the impregnation, give your lining time to dry completely and proceed to painting or varnishing it.

Applying varnish

Varnish or paint is applied to wooden panels using a brush or spray (it all depends on the volume of work being performed).

Varnishing of panels

When processing, follow the following rules:

To apply the varnish, use a brush with natural bristles.
If the varnish is water-based, be sure to mix it thoroughly to avoid unevenness during application.
Apply all coatings along the grain of the wood.

Don't limit yourself to just one layer. After the first one has completely dried and pre-sanded, apply the second one.
When using a tinted coating, adhere to the principle that each subsequent layer should be less pigmented. Then the finished varnished surface will acquire incredible depth and shine.

Now you are ready to create the perfect wood paneling.

For many craftsmen completing interior wall cladding with wood, or starting to repair such cladding. You have to choose - what is the best way to cover the lining inside the house?

And, despite what is available on the market today widest choice protective and decorative materials for wood, select the right composition sometimes it can be very difficult.

Protection and durability of the lining

Principles for selecting a protective composition

When choosing what to cover the lining inside the house with, we must first answer three questions:

Does wood siding need to be coated at all – or can it be left uncoated?
In what room will we cover the wood paneling - wet or dry?
Is it necessary to tint the lining, or is it necessary to preserve the natural color of the wood as long as possible?

It is based on the answers to these questions that we will select materials for impregnation and coating of the surface of the lining indoors.

Note!
In this article, we are not considering how to cover the lining outside the house.
The whole point is that external cladding completely different requirements are put forward, which means that the composition for processing the lining must be fundamentally different.

Lining without coating

The very first option that should be considered is lining without any coating at all. And in principle, such a solution, despite its apparent impracticality, has its reasons.

The point here is this: the wooden paneling of the room, left without protective coating, darkens over time, and this happens quite quickly. And here your own taste comes into play - if the darkened wood suits you, from an aesthetic point of view, then spend money on additional processing not worth it.

Advice!
Not so long ago, a popular way of processing lining was to artificially age it using a blowtorch. After several passes, the lining not only darkened (as in the photo), but also released resin, which gave it an interesting appearance.

Another aspect is purely practical. Finding a high-quality and effective coating for sauna lining is quite difficult, and it is quite expensive.

That is why many decide not to waste time and money, but simply periodically change the lining - for example, once every five to seven years. If you use inexpensive wood cladding and install it yourself, then this option has a right to exist.

Covering functions for lining

Well, what if we decide to choose the most suitable covering for lining inside the house, then it is necessary to understand what functions these coatings can perform.

For the interior cladding of a clapboard house you need:

Ignition protection. It is achieved by treating wooden panels with fire retardants – substances that significantly reduce the flammability of wood.
Rot protection. Antiseptic treatment is very important, especially where the lining comes into contact with moisture.
For example, when you choose what to cover the lining of a loggia with, be sure to include an antiseptic composition in your purchase list.
Protection against mechanical damage. Although it is primarily the wooden floor that needs to be protected from chips and scratches, additional strengthening of the wall cladding will also not hurt.
UV fade protection. The more effective this protection is, the slower the wood changes its original color.
In addition, the outer covering of the tree should provide it with an attractive appearance.- and this means that we can either give the lining the shade we need using tinting, or simply apply a transparent varnish with a matte, semi-matte or glossy surface.

As a rule, several compounds are used simultaneously to treat wooden cladding inside a house (see). This is due to the fact that it is almost impossible to combine all the functions in one product.

Compositions for processing lining

Impregnations and stains

When choosing whether it is better to cover eurolining or regular lining, we need to consider different types compositions. And first of all, we will look at substances that penetrate into the wood itself - impregnations and wood stains.

Drying oil- an option that is hopelessly outdated and is used today exclusively for processing utility premises.
It does a good job of protecting wood, but within a few years after application it becomes dark and the impregnated wood becomes covered with a sticky film.
Protective impregnations– used to impart antiseptic and fire-fighting properties to the lining. As a rule, protective impregnations are applied to a wooden panel on both sides, so the application must be done before installation.

Note!
As a rule, the instructions for protective impregnation contain information about its compatibility with various finishing coatings(varnishes, paints, etc.)

Antiseptic film coatings are similar in purpose to antiseptic impregnations. Quite rarely they are used inside the house, but if you are looking for something to cover the lining outside, then antiseptic coatings are exactly what you need!
Stains are used to give wood color and also to disinfect it. They are used in the same way as impregnations.

The most popular manufacturers of impregnations and stains for lining are “Tikkurila”, “Senezh”, “Pinotex”, etc. We recommend choosing compositions for wood processing from trusted manufacturers - even if their price is slightly higher, the quality is guaranteed not to disappoint!

Varnishes and paints

As a rule, after treating the lining with penetrating compounds, it looks somewhat unpresentable.

That is why, in addition to staining or impregnation, the lining is opened with a protective varnish with decorative properties, or paint.

Varnishes are used if we want to preserve the natural color of the lining and the texture of natural wood. They are best suited for interior decoration - they are non-toxic, fireproof and easy to apply.
The texture of the varnish can be either matte or glossy.
If you are looking for something to cover the lining to prevent it from darkening, choose a transparent varnish with high UV resistance. But if you want to “age” a light lining a little, give it a darker shade, then it is better to open it with varnish with tinting additives.
Alkyd varnishes are highly durable, which is why they are most often used to treat floorboards or parquet. The lining should be coated with alkyd varnish only in those places where it experiences mechanical stress.
Paint for lining is used less often than varnish - but, nevertheless, it is used. The best solution is a translucent paint that partially preserves the wood texture. The most common brands of paint for lining are “Belinka”, “Texturol”, “Senezh”.
Wax paints are the best, but at the same time, the most expensive and difficult to work coating for lining inside a house. The basis of such paints is most often natural linseed oil.

Note! How they cover the lining in saunas and baths is a separate question! For these purposes, it is best to use specialized compounds such as “Supi saunasuoja” or “Evrotex-Sauna”.

Lining coating technology

Preparation for coating

Covering the lining with protective and decorative compositions is done in the following sequence:

We carry out the initial processing of the lining: dry it, clean the surface with a brush-scraper, and then sand it, sanding down small irregularities. In the same way, sanding must be carried out before renewing the lining that was previously varnished.
If there are darkened areas on the surface of the wooden cladding, we deep clean the lining using wood bleaches (Senezh Neo, Frost, etc.).

After bleaching, rinse the paneling thoroughly with water and dry it again.
To fill the pores in the wood, we treat the panels with a primer. The primer improves the adhesion of the lining to the varnish and reduces its consumption.
After applying the primer, we impregnate the wood with antiseptics and fire retardants. You can also use compositions that provide comprehensive protection tree.

After the lining, treated with primer and impregnation, has completely dried, you can begin painting or varnishing it.

Applying varnish to clapboard sheathing

We apply varnishes and paints to wooden panels using brushes or sprayers (depending on the material and area of the surface to be treated). You can study the application technology in detail by carefully watching the video instructions included with the article.

Processing is carried out according to the following scheme:

To apply the varnish, use a brush with natural bristles.
Mix the water-based varnish with the tinting thoroughly - otherwise the tinting of the lining will be uneven.
On the wall covered with clapboard, apply the first layer of varnish, moving the brush along the grain of the wood.
Leave the applied layer until completely dry. After the varnish has completely dried, sand it and proceed to applying the next layer.

If we plan to cover the eurolining with tinted varnish, then each subsequent layer of varnish should contain less tinting pigment than the previous one. This gives the varnished surface depth and an attractive shine.
Make the last layer of varnish transparent and do not sand it after application.

Now you know how to cover the lining in your house, and most importantly, you know how to do it! Therefore, if you are faced with such a task, you will be able to cope with it yourself, saving both time and money!
