Which covers the surfaces of the walls or ceilings in the house - it seems to be quite simple. The main thing is to decide on the choice of paint or other means that can transform the wood. However, the range of paint and varnish compositions in specialized stores is very diverse, and this is probably why painting the lining inside the house raises some questions.
Wood is traditionally characterized as durable and durable material, but subject to proper drying and treatment with various compounds, including paint. These products can protect the lining from damage by insects or fungi, dirt, excessive moisture and, conversely, drying out. In addition, the processing of this natural facing material flame retardants will significantly reduce its flammability.
Therefore, it is worth considering not only the coloring itself, but also the preparatory measures for this process, as well as the materials used for these procedures.
The most popular types of lining for finishing walls and ceilings indoors are those made from coniferous species, and among them, pine is considered the most affordable. This wood has some peculiarities and therefore requires an individual approach when painting it. These nuances will also be considered when detailed description process technology.
Solutions for preparing and painting wood
Almost all paints available in hardware stores are suitable for painting natural lining. However, for interior decoration It is worth choosing those that are as safe as possible for the residents of the house, both during painting and during the operation of the finish. In addition, it is important to select protective equipment that does not harm the ecological atmosphere in residential premises.
Since on initial stage the lining is treated with protective agents, then it is worth considering them first.
Protective means
Solutions for preparing lining for painting are designed to protect it from mold, harmful insects, the destructive effects of ultraviolet rays, as well as from excessive moisture absorption. In addition, some of them reduce the fire hazard properties of wood.
These substances, as a rule, do not change color and do not cover the textured pattern of the wood, since they are translucent. However, in this series there are also compositions that, to a certain extent, also perform an additional decorative function.
Preparation for painting natural lining is divided into several stages - cleaning and sanding the wood, priming and impregnation. For these operations can be applied special compounds for different purposes:
- are used to prevent fungal damage to wood, to “treat” and stop the growth of already existing mold stains, to protect against insects that destroy the structure of the wood. These funds are divided into two groups:
Prices for wood preservatives
wood antiseptics
— Coatings that form a protective film on the surface of the lining are used in cases where the wood will come into contact with water, for example, when lining bathhouses.
— Impregnations that penetrate into the wood structure require further additional coating in order to avoid leaching of the product, as well as due to the toxicity of some of the components of the solutions.
In addition, antiseptics are divided into four types based on the basis on which they are made:
— Products based on organic solvents have high protective properties and are suitable for wood fixed both outside and inside the structure. But they are used extremely rarely, as they are quite toxic and flammable.
— Solutions for oil based suitable for wood subjected to static loads, as well as in difficult climatic conditions, therefore they are most often used for external cladding or for lining used to line balconies or loggias.
— Water-soluble protection products are used to cover the internal wood cladding for further application of paints and varnishes on water based. They are non-toxic and dry quickly, but over time their antiseptic properties decrease significantly;
— Combined antiseptics contain high-carbon and oil components. Solutions can be used for exterior or interior decoration, and are also used in rooms with high humidity, creating high level wood protection. The cost of combined solutions is significantly higher than the price of other types of antiseptics.
- Bio-moisture-proof antiseptics have, in principle, the same purpose, however, they also create a protective moisture-repellent barrier on the lining, and are also able to give it additional decorativeness, emphasizing the texture of the wood. Therefore, by using such an antiseptic, you can solve several problems at once, since you won’t have to apply products for different purposes - this will save time, since you won’t have to wait for the layers to dry. It is these qualities that make biomoisture-proof impregnations one of the most popular.
- Fire retardants - These are solutions that make wood more fire resistant. They can also be divided into two groups:
— Compositions of the first group work to block the flame, since when heated they foam and form a protective layer on the lining.
— The second group of compounds contains salts, which, upon contact with fire, release gases that prevent combustion and the spread of flame.
The most effective fire retardants are those that contain tripolyphosphoric, orthophosphoric and pyrophosphoric acid and sodium salts.
- Biopyrenes - these are impregnating compositions with an antiseptic and fire-retardant effect, which are suitable for internal and external wood treatments. Such compositions will help reduce the period of preliminary preparation of wooden finishing, and often also save money, since you will need to purchase not two separate solutions, but one that will perform both main functions.
- Whitening products are used for wooden lining if there are unwanted dark or bluish stripes or spots on it. In addition to the whitening effect, such compositions also create a protective antiseptic layer that will resist the formation of mold.
Bleach products typically consist of two components that are mixed before being applied to the wood. Such solutions may consist of different chemical compounds, and some of the bleaches must be washed off from the surface of the lining after a certain time, while others do not require such rinsing. Therefore, before purchasing such funds, you need to pay special attention to this factor.

- Primers - these are solutions that can also be called protective. But in addition to these qualities, the primer gives the wood surface smoothness and good adhesion, which simplifies further coating of the lining with paints or varnish.
Primers are usually water-based and can be clear or opaque. If you plan to preserve the textured pattern of the wood, then choose a transparent primer solution. In the case where there is an intention to apply a dense decorative layer of paint, any of the primers can be used, but an opaque one will create a more even and smooth base
Transparent primers do not create stains on the wood surface. protective film– they penetrate into the structure of the material. Treatment of the surface of the lining, carried out with primers, significantly reduces paint consumption and increases the durability of the applied finish.
Varnishes – protective and decorative compositions
Not only in quality decorative covering, but some varnish compositions are also used to protect wood. They are produced at different bases:
- Oil varnishes contain natural or artificial resins, natural modified oils, as well as solvents and driers. This type of varnish, after drying, forms a fairly strong film on the surface, which gives the wood a natural ocher tint. Oil solutions used to cover clapboards, floor boards and other wooden surfaces inside the house.
- Alkyd varnishes are made from pentaphthalic and glyphthalic synthetic resins with the addition of driers. These compositions are quite often also called oil-based, since oils are used in them as a solvent. However, in terms of their performance characteristics, alkyd varnishes are superior to oil varnishes, and therefore can be used for external work.
- Alkyd-urea varnish solutions consist of amyl-formaldehyde and alkyd resins. They are capable of drying out normal temperatures only if they contain acidic hardeners, which are added to the mixture immediately before starting work, since after mixing their lifespan is limited. Such varnishes form a hard, durable film on the surface of the wood that is highly wear-resistant. Thanks to these qualities, alkyd-urea varnishes are well suited for interior work and not only for processing lining, but also for varnishing parquet.
- Polishes and alcohol varnishes give the surface special strength and shine, but their biggest disadvantage is that they do not protect wood well enough from moisture, so they are not recommended for use on lining installed on an unheated balcony or loggia.
The solutions are made using natural resins, so they have a high price and are not popular.
- Nitrocellulose varnish is made from cellulose nitrate and a mixture of organic solvents. In addition to them, to achieve the necessary protective qualities of the compositions, synthetic resins are added to them. This type of varnish creates a durable hard coating on the surface of the wood, which is transparent and practically does not change the color of the wood. The varnish is intended for indoor use.
- Acrylic varnishes are a water-dispersed solution of polyacrylates. The product is distinguished by its environmental friendliness and almost complete absence of odor. Also used for coating wooden coverings and products used in residential premises. However, the film formed on the surface is still not highly resistant to abrasion.
- Polyurethane varnishes are water-based, but are characterized by high strength and abrasion resistance. These varnishes are an environmentally friendly material, and if they are chosen to cover the lining, this will significantly increase the durability of the protective layer.
Polyurethane solutions are used to cover floors and other wood finishing elements indoors. These varnishes have a fairly high price, which is fully justified by their high performance characteristics.

Paints for coating wooden lining
For decorative coating of lining, compositions made on different bases are used. Some of them are universal and are used for both internal and external exterior finishing, but there are also those that are intended exclusively for internal use. Therefore, when buying this decorative material, you must definitely study its main characteristics, which are usually indicated on the packaging, and also consult with the seller.
So, the following colorful compositions can be found on sale:
Oil paints are suitable for indoor lining, but they have many disadvantages - Oil paints can be called universal, since they penetrate quite deeply into the structure of the tree, increasing its resistance to various environmental influences, making it moisture resistant. Disadvantages oil paints we can call them long drying, rapid fading under the influence of ultraviolet rays and a decrease in the breathability of wood. Therefore, it is still better to use it for interior decoration, and even then - not always.
- Acrylate paint compositions - these are aqueous solutions that, in most performance characteristics, are superior to oil-based paints that can create wood reliable protection, preserving its color. This type of solution is quite elastic, therefore it has good adhesion to the surface and does not crack or deform when temperatures change. Due to its qualities, the paint can be used for external and internal work.
- Alkyd based enamel paints used for painting lining both outside and inside the building, forming a protective glossy layer for the wood. Therefore, a freshly painted surface looks very aesthetically pleasing. However, over time, colored paint tends to fade, and white paint tends to turn yellow. In addition, drying alkyd paints- a rather lengthy process, which is always accompanied by a not very pleasant odor due to the organic solvents included in the composition.
- are able to preserve the textured pattern without painting it with a thick layer - to do this, they must be diluted with water to the desired consistency. If necessary, apply a thick layer of paint to the lining; the paint should not be diluted.
These are environmentally friendly solutions that do not have an unpleasant odor and do not emit harmful fumes. The paint dries quickly and adheres well to the primed surface, but is still inferior in its characteristics to varnishes. Not resistant to abrasive influence.
- Silicate paints are made on the basis liquid glass, therefore they have quite a lot of positive characteristics. Such compositions are not exposed to ultraviolet rays, high humidity and temperature changes can increase the fire resistance of wood. This is an environmentally friendly material, it does not emit harmful substances and is odorless.
Due to their characteristics, silicate paints can be used for painting different surfaces, as they have high adhesion, and lining is no exception. These paints are especially suitable for wooden cladding of a loggia or balcony. The disadvantage is that in the future, if repainting is necessary, you will need to use silicate paint again - no other paint will work. Another “minus” is the rather narrow range of possible colors.
- Silicone paints are made on the basis of silicone resins, and are one of the most durable types of paint compositions, but also the most expensive. This type of paint has high performance characteristics: the created coating can withstand mechanical stress, including abrasive loads, has good vapor permeability, color stability and fading, moisture resistance and a long service life, which is about 25-30 years. In addition, silicone paints are not only able to protect wood, but also hide small defects on its surface.
- Wax paints, based on linseed oil, are a traditional material for internal processing of wooden lining. These compounds give the lining a matte shine, preserving the color and pattern of the wood. This paint is especially suitable when the wood initially has a beautiful texture, which is simply a pity to hide with another opaque or translucent composition. Wax paints began to be used instead furniture wax, since they are easier to apply to the surface and have a number of other advantages:
— penetrate deeply into the wood structure, which makes the surface water-repellent;
— do not change the natural color of the wood;
— the characteristic color of wax appears after drying and rubbing the lining with a brush;
— the paint does not contain any “chemical” solvents and is an environmentally friendly material;
— if desired, the wax composition can be tinted to the desired shade;
— is different economical consumption composition.
Now, after considering the basic compositions used for preparing and painting natural lining, you can move on to instructions for performing the work.
Calculator for calculating the amount of paint for lining
When calculating the amount of paint to carry out finishing works Many inexperienced consumers get confused when they take volume units as the unit of measurement. However, the density of paint differs significantly from the density of water, and a kilogram of composition does not at all mean the usual liter. As a rule, packaging is carried out, and the average consumption of paints and varnishes is measured in weight equivalent - in kilograms. The calculator will give exactly this value, taking into account a 10% margin.
A huge number of the most popular materials are made from wood. different materials and household items. Wood is always in price and never ceases to be fashionable. This is one of the few materials that always remains in trend. Today there is a very popular style - eco.
Natural materials are not only safe, but also popular. Despite such a positive start, it is worth noting that wood is not only a beautiful and stylish material, it is also very capricious. You need to take care of it constantly if you want it to serve you for a long time and maintain its original appearance. The question immediately arises - what is the best way to treat the lining inside the house?
Methods for protecting wood products
There is no shortage of such materials on the market. The variety of different mixtures, consistencies and compositions for treating wooden surfaces and materials is sometimes confusing, and you don’t even know what is best to choose.
When deciding on a protective mixture, you must consider the purpose of protection:
- Some compounds protect wood from fading;
- others repel moisture;
- still others protect against various types of damage.
How to treat the interior of the lining wooden house, in order not only to protect it from external factors, but also to make it elegant - this is a question that lovers of the practical and beautiful at the same time have asked more than once. Such mixtures exist and are available to everyone, the main thing is to know which ones to choose.
To process wood with your own hands, you need to know a few rules and the name of the compositions that will be needed for the process in question.
So:
- mandatory use of antiseptics;
- a primer will also be needed to protect the material;
- fire-resistant impregnations;
- varnishes of various types;
- biological oils (preferably);
- Don’t forget about the means to remove the previous coating you don’t need.
Now you know how to treat the lining indoors, you already have a list of compositions, so there shouldn’t be any problems with the search. In any hardware store or market, in the home and construction goods department, you can purchase everything you need. The photo shows the compositions that you will need to protect the coating you have chosen.
Paints and varnishes for wood processing
Primer
One of the main compounds needed to protect the coating is a primer. This mixture is also a biological defense. It can be used for both external and internal work.
- Even if the tree is slightly damaged, such a composition can be used, and even necessary.
- A primer coating extends the life of any wood material.
- Among other things, the primer gives the product a well-groomed appearance.
Decorative and protective coatings
Relatively recently, new paint and varnish mixtures have appeared on the market that not only protect wood, but also paint its surface in any color. Now, thanks to such mixtures, you can protect and create unique design in my house.
A positive point in the characteristics of such compositions is that when painted with them, the texture of the wood is visible and remains the same. This mixture already contains an antiseptic; you do not have to buy it separately.
Some of these mixtures can even be used for wet wood. They can be used for both interior and exterior decoration.
The resulting tones are very soft and slightly matte. Temperature changes and ultraviolet rays do not affect the quality of the mixture for a long time. For this reason, you definitely won’t need the next treatment of the lining inside the house for ten years.
Use of scuba tanks
Some argue that it is easier to choose a different material than to process the lining indoors, but in fact this is not the case, you need to know. What to process and how to carry out this process without extra costs and problems.
Excellent for wood processing. From the name it was already possible to understand that they contain water, and to a greater extent than all other components.
A number of advantages of this material for covering wood:
- Absence of any smell;
- It dries very quickly;
- There are no organic solvents in the composition.
There is another type of scuba diving - hydrophobic. Thanks to their composition, they protect wood from moisture and repel water, which means they have a wide range of applications.
The price of such products is an order of magnitude higher than typical analogues, but at the same time you get one hundred percent protection for many years. In rain, snow and hail, your wooden surface and structure will look perfect.
Oils
Treat wooden surfaces with oils - good idea, it is even better to use their combined formulations. The oil has such a structure that when applied to the surface, it saturates them well from the inside, getting into every pore.
Protects the tree and delays:
- dust;
- dirt;
- moisture;
- Sun.
Working with such tools is a pleasure; there are no unpleasant odors, you can only smell the plant from which this oil is made.
The hue of the wooden surface becomes golden. If you want to receive bright color wood, you can paint it any color you like.
Treatment with protective compounds
The quality of your work will depend on attentiveness and accuracy, as well as on the correctness and consistency of compliance with all rules and recommendations. Full instructions presented on video:
Conclusion
Now you know how and with what to treat the lining inside the house, what compounds are best to apply and how to extend the life of any wooden surfaces. Whatever you do, whatever work you do in your home, remember that diligence and patience will lead you to success and achieve a positive, expected result.
You should not skimp on protective equipment, because they justify their cost and extend the life of wooden materials.
Lining is an excellent finishing material, especially for a private home or cottage. It can be used to cover walls, ceilings, slopes, doors, balconies, etc. This material has excellent thermal insulation performance, beautiful appearance, and most importantly - it is environmentally friendly. The main disadvantage is fragility due to susceptibility to rotting and fungal formation.
To extend the life of the lining, it must be protected by applying an additional protective layer to its surface. It is important to decide how to cover the lining indoors so that it becomes reliable and has a beautiful appearance.
But is it necessary to cover the lining with paints and varnishes indoors, where it is not threatened by an aggressive environment such as atmospheric precipitation and temperature changes? The fact is that, albeit to a lesser extent, there is still moisture in the room, and the influence of temperature also acts. All these factors are especially pronounced in country houses that remain without heating in winter.
Materials for finishing lining
The finishing material must perform two main functions - decorative and protective. Exist following materials, which can be used to cover the lining.
Lining without coating
Any coating to one degree or another contains harmful chemical components. Because, to keep your home environmentally friendly, it is not covered with any additional funds. The wood itself has beautiful colour and texture. In addition, this way you can save on the purchase of paints and varnishes.
However, in order for the lining not to darken and to serve for a long time, it still needs to be protected with additional substances. Here you need to make a choice between durability and environmental friendliness.
Oil paint coating
Most simple, easily accessible and widespread method of finishing lining. It is not difficult to buy a brush and oil paint of any color and paint the lining. What kind of paint to use depends on the wishes of the owner of the house.
Advantages:
Flaws:
Painting with water-based acrylic composition
This type of coverage considered a compromise between aesthetics and protective properties. Acrylic paint consists of a clear varnish and a tinting mixture. After double processing, the lining acquires desired color, the texture is preserved and all protective properties are fulfilled.
Positive sides:
- beautiful appearance;
- high protective properties;
- environmental friendliness;
- versatility.
Negative:
- high price;
- a labor-intensive process of preparing material for painting.
Coating with acrylate paint
Acrylate paint is more decorative material than protective. It has a number of advantages over oil paint, but its cost is higher.
- durability;
- resistance to temperature influences;
- dye does not crack or swell;
- beautiful appearance;
- protective properties are weak;
- high price.
Processing with decorative azure
Decorative azure is effective protection wood from external influence. It gives the necessary color to the material and at the same time the wood texture stands out clearly.
Advantages:
- moisture resistance;
- heat resistance;
- beautiful appearance;
- environmental friendliness;
- vapor permeability.
The only disadvantages include material cost. It is higher than oil paint, but the technical and physical indicators are much better.
Opaque enamel coating
Enamel components are practically do not differ from the components of oil paint, the whole difference is in proportions. Enamel has significantly more film-forming substance and less filler. To ensure an opaque layer of coating, triple application of enamel is performed.
Advantages:
- coating strength is higher than paint;
- higher hardness;
- better elasticity;
- abrasion resistance;
- more pleasant appearance due to the greater shine of the material.
The cost is correspondingly higher than oil paint.
Treatment with acrylic aqualac
Aqualak is water-soluble acrylic latex with additives, performing a stabilizing function. When dry, the varnish forms a very glossy, silky durable surface. It performs more protective functions, but emphasizes the natural beauty of the wood, giving it shine.
- saved appearance of the lining;
- fire resistance;
- moisture resistance;
- good adhesion;
- durability;
- economical consumption;
- simplicity applications.
Negative sides:
- high price;
- requirements for temperature and humidity in the room during work.
Alkyd varnish coating
The binder for alkyd varnish is alkyd resin, which made from wood or linseed oil. Such material is able to penetrate deeply into the wood.
Positive sides:
- good expression of the texture of the material;
- strength;
- moisture resistance;
- perfect adhesion.
- complex requirements for the indoor microclimate during work;
- long process of drying the material;
- requirements for the thickness of the varnish layer.
Processing lining with stain
Water based stain has no protective functions, but is performed only as decoration. An alcohol or solvent based stain protects the wood. This material gives the lining any shade.
Advantages:
- environmental friendliness;
- beautiful appearance;
- no odor;
- moisture resistance;
- ease of work;
- low cost.
Flaws:
- water-based stain lifts fibers;
- not alcohol based dries too quickly, and stains may form.
Bleach treatment
Wood bleaching is carried out using active chlorine. Thanks to this tool you can hide lining defects and give the material a noble white tint.
- hides wood imperfections;
- beautiful appearance;
- durability.
- low protective properties;
- probability destruction of the top layer linings.
Bactericidal treatment
Bactericidal treatment is required to protect the lining from mold, mildew, rot and various bacteria. This antiseptic has potent chemicals. Therefore, the question arises: what is the best way to cover the lining indoors for bactericidal protection. For this purpose, there are special mixtures for interior work. An antiseptic can also perform a decorative role with the help of an antiseptic stain.
Advantages:
- high degree of material protection;
- perform an additional decorative function;
Flaws:
- harmful substances are released;
- the need for pre-treatment.
Your home is your fortress, a reliable rear, a place for mental relaxation. Therefore, the environment in it must correspond to all these parameters. What creates comfort and peace in the home? Of course, the corresponding interior. Many owners, to create an atmosphere of comfort, warmth and a special aura of goodness and well-being in the house, use ordinary wooden lining as interior decoration, which has again come into fashion in recent years.
But beautiful finish, as well as beautiful woman, requires a reliable defender for himself.
Lining protection
No matter what kind of wood the wooden covering is made of, its protection must be approached with all responsibility. After all, its natural beauty and durability depend on this.
There is currently no shortage of protective equipment. What types protective coatings exist and what properties do they have? Experts highlight the following:
1. Translucent and opaque antiseptics so-called glazing and covering.
These products protect the wood from fungal growths, darkening and rotting. They can serve as protection from 3 to 5 years.
Glazing coatings, protecting the surface with a translucent film, highlight the structure of the wood and emphasize its beauty.
Coating products not only protect, but also decorate the tree, hide its defects, highlighting its relief. We can recommend: Valtti Techo, Vinha. All of them are produced by the Finnish company Tekkurila.
Video - how aqualak works on wood:
2. Oil paints- a good and fairly common type of protection. Their distinctive feature is their special resistance to adverse natural influences.
They are well absorbed into wood and prevent deep penetration water vapor into its structure.
Of course, slow drying and change color range(burnout) are among their negative qualities, but in general they are quite suitable for protective purposes. Durosil and Teho are commonly used types of oil paints for wood.
3. Acrylic paints long years retain their color and shine. While protecting the wood, they at the same time allow it to “breathe”, and the substance included in their composition - acrylate - prevents the dye from cracking, maintaining its original appearance for a long time, can last up to 10 years. Some of the representatives are Pinya Pro and Pica Techo.
And the most effective and popular defenders among consumers, without any doubt, are various: polyurethane, alkyd, water-based varnishes. Which lining varnish perfectly protects and is best suited for the interior, as well as its distinctive features, we will look in more detail.
Water-based varnishes - features, advantages and disadvantages
Choosing a varnish for the lining inside a house is not an easy task.
Experts who work with various types of wood know this firsthand. First of all, they advise paying close attention to the water base. and their individual characteristics:
- High degree of protection from exposure to adverse environmental factors.
- Durability. They note that they stay on the surface for 5 to 7 years.
- Decorative features that positively affect the structure of wooden coverings and their appearance. They do not spoil the natural color of the wood and do not give a yellow tint.
- Environmental friendliness. They do not emit harmful fumes that have a detrimental effect on the health of household members. They do not have allergic components.
- Quick drying (up to 24 hours) and self-leveling, which makes it possible to obtain a perfectly flat surface.
- Fire safety. They contain components that inhibit wood fire.
The main feature of such paints is that, while forming a transparent film on the surface of the wood, they do not spoil the surface texture, leaving a natural wood pattern and color.
In addition, they do not contain solvents that cause an allergic reaction in the body.
Many water-based varnishes contain one or two components. What does it mean?
One-component ones do not contain a hardener and are easier to use. However, they have a significant drawback - they are not very durable.
Two-component varnishes contain a hardener, which better protects the surface of the wood and prevents it from crumbling or swelling for many years.
Speaking about water-based varnishes, experts, based on their features and consumer reviews, give them an excellent rating and believe that they are the best suited for interior decoration.
However, minor disadvantages should also be noted - you should not use strong detergents when cleaning and washing. chemicals. May fade. Therefore, you need to carefully choose detergents and cleaning agents, and preferably, on a natural basis.
Preparing the lining for varnishing
So that the varnish for the lining lays beautifully and the surface of the wood is smooth and pleasing to the eye, it needs to be prepared for painting.
First of all, you need to clean the wood from dirt, dust and remove all irregularities. To do this, you can walk over the surface with a steel or hair brush.
Then use pumice and sandpaper to clean off all roughness, especially carefully at the ends and chamfers. Then the wood can be washed with warm water with the addition of 2% soda. And let it dry well. This is the first stage of preparation.
Second stage preparation is to treat the wood with a primer. This stage is very important. The primer fills the entire porous surface of the wood, which significantly saves paint consumption. You can apply the primer either with a brush or a roller; many people use a spray gun to speed up the process.
Now you can begin the varnishing process itself.

Varnishing of lining with a water-based composition
Covering is not very difficult. The main thing is to know the operating technology and follow the operating instructions.
- Do not dilute with drying oil or other thinners. Water-based varnish may curl. They are diluted only with water.
- The dye should not be stored at sub-zero temperature, especially to paint. May freeze and become unusable.
- Stir thoroughly before use until smooth.
- To apply varnish, it is better to use brushes made of natural bristles, small in diameter. They crumble less and do not leave unwanted fragments on the surface.
- The use of a spray gun is encouraged. The varnish will be evenly distributed throughout the wood.
- You can also use a paint roller, but with short pile.
- The varnish should be applied in a continuous motion along the surface, then it will lay down in an even layer.
- It is advisable to make two or three such layers. Which will give a rich, uniform color.
- When covering the lining with each subsequent layer of varnish, you must allow the previous layer to dry. After drying, it is better to sand each layer with zero-grade sandpaper before applying the next layer of dye. Then the surface will delight the master with a deep, uniform color.

Prices
Water-based lining varnishes have different prices. It all depends on the manufacturer and the quality of the product. Here are some of them:
- PANELLILAKA- a water-based mixture for varnishing walls and ceilings made of wood, produced by the Finnish company Teknos. The cost is 409 rubles for 0.9 liters.
- Varnish TOBAGO, the same company Teknos. It is also used for interior work and is water-based. Price for 0.9 liters is 209 rubles.
- PANELLI ACCA matte- also water-based from Tikkurila. Used for wooden coverings. Price for 0.9 liters is 475 rubles.
- PANELLI ACCA semi-matte- intended for wood panels. Water-based. Price for 0.9 liters 637 rubles.
As you can see, prices vary greatly. You can decide for yourself which varnish to choose. We hope that our advice will help you make your home cozy and safe.
Wood is one of the few finishing materials, which needs processing after installation on walls and other surfaces. The most common finishing method is lining varnish, which can be used indoors and on the facade.
Types of varnishes
Any varnishes are a transparent or translucent material that is used to coat wood in order to protect it and improve its external aesthetic qualities. Before choosing what varnish to coat the lining inside the house with, you need to compare the advantages and disadvantages of all products of this type.
Photo - shades of varnish for lining
These materials are classified according to their composition, properties and area of use. There are varnishes for interior and exterior use; they differ from each other in some qualities (for example, outdoor coating should be indelible) and smell. Where the coating is applied are divided into:
- Parquet. Used to cover wood on floors. You can choose any color and properties (glossy, matte surface). The key difference from other products in this series is their high resistance to mechanical stress: friction, walking, etc.
- Furniture. For finishing furniture, special compounds are used that provide long-lasting shine and unchanged color of wood over many years of use. Most of them are made on a wax basis;
- Construction boats. They have an increased coefficient of resistance to moisture, which allows them to be used in shipbuilding. Many craftsmen use such products to decorate utility rooms (bathhouses, garages) or facades of residential buildings;
- Decorative. The widest group. Intended solely for room decoration. This varnish can be glossy or matte. Often indelible with water and with excellent antiseptic properties. Used to cover walls in residential buildings, utility rooms (on the loggia, dacha, steam room, etc.), sometimes for finishing the facade.
Photo - matte shine Varnish is a coating for lining, which, depending on the main components, has not only decorative, but also protective properties. Depending on the composition they are:
- Alkyd;
- Acrylic;
- Nitrovarnishes;
- Oily;
- Epoxy;
- Polyurethane.
Let's look at the features of each group. Alkyd varnishes for covering wooden lining can be used on the balcony, in the corridor, living rooms. They are universal and have high resistance to external aggressive factors (high humidity, temperature changes). These paint material They penetrate deep into the wooden structure, so they take a very long time to dry - sometimes the hardening time of the coating reaches up to 3 days. Disadvantages also include the high cost of the coating and the likelihood of fire.
Photo - alkyd Colorless acrylic varnish is the most environmentally friendly option for finishing wooden panels. They preserve and prolong the natural color of the wood, while helping to protect it from fire and rot. But they have low resistance to moisture. For example, if acrylic-based varnish is used in a bathroom or on a balcony, 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 lining is water-based (aqua) and solvent-based. Aqualak (Tikkurila, Pinotex, Poly R and others) has a wider range of uses due to the fact that it does not deform the wood. At the same time, the solvent is more resistant to irritating factors and can even be used to cover the floor.
Transparent nitro varnish has no pronounced odor and dries very quickly; at the same time, its price is almost two times lower than options with acrylic or alkyd base. It is used for painting eurolining inside and outside the house, but it has a significant drawback. The product contains toxic substances that can cause poisoning. After the mixture dries, they are harmless, but it is not recommended to heat walls with such a coating, and it can only be applied while wearing a protective mask.

Depending on the oil and resin in the composition, the coating may have different colors: Light brown to dark chocolate. After hardening, they form a hard film on the wall or ceiling that is easy to clean. On top of it it is carried out further processing. Among the advantages: moisture resistance, protection of wood from exposure to UV rays, extension of the durability of the coating. The disadvantages include a high level of fire hazard.

To renew the wall covering, you need not only to know how to remove varnish from the lining, but also how to use the coatings correctly. To begin with, the walls (floors, ceilings) are washed, for this we take damp cloth with special wood cleaners. This is necessary to remove dust and dirt from the wood pores.
Next, the old coating layer (if any) is removed or the lining is sanded. For this purpose they are used as special grinding machines, so sandpaper low abrasiveness and metal brushes. This is necessary to level the surface and eliminate nicks. After this, you need to paint the wood with drying oil. It can be bought at any hardware store. The drying oil will fill microcracks in the lining and help improve adhesion; after the drying oil has dried, a primer is applied to the walls.
