Where can I treat the car with liquid glass. The use of liquid glass for waterproofing

A wooden house is an environmentally friendly and comfortable housing, which is characterized by durability and reliability, aesthetic appeal and a cozy atmosphere inside the building.

But do not forget that wood is a living natural material. Therefore, it is subject to negative environmental influences. These are high humidity and dampness, ultraviolet rays and insects, temperature changes and other harmful factors. During operation, the wood gradually ages, darkens or turns yellow and loses its original appearance.

Special protective and decorative compounds for wall treatment will help save wood. In this article, we will look at how to paint a wooden house outside. Painting the exterior walls of a wooden house is an obligatory stage in the construction and finishing of a country log home!

It is necessary to paint the house not only after construction and shrinkage, but also during operation. Experts recommend painting wooden buildings every 5-8 years, depending on the type of paint and varnish materials, and it is advisable to treat an old house more often.

What kind of paint to choose

Today, manufacturers offer a variety of paints and varnishes. Resistant and coarse compositions are suitable for outdoor wood processing. Let's look at which are best used for a log house.

Antiseptic varnishes are glazing (transparent) and covering (opaque). The first type preserves the natural color and emphasizes the texture of the wood, while the second will help achieve the desired shade and shine. Such products penetrate deep into the wood and protect the material from rotting and mold, the negative effects of water and humidity. When choosing, please note that the coating compositions will last 6-7 years, but the glazing varnish will have to be updated every 4-5 years.

Acrylic (acrylic) paints are the most sought-after products among the owners of country houses. They are best suited for natural wood, as they are absolutely safe. Such paints allow the tree to "breathe" and guarantee good air exchange. The acrylic composition creates an elastic dense coating that protects the wood from moisture, cracking and fungus.

Acrylic paints are expensive, but at the same time they create a durable and reliable coating that will last a long time. You won’t have to repaint the paint more often than once every 8-10 years!

Oil paints are well absorbed and penetrate deep into the structure of the tree. They effectively protect log walls from dirt and moisture. But today, such products are losing popularity, as they dry for a long time. In addition, over time, painted wood changes color and shade, yellow spots appear on the surface. To avoid this, you will have to repaint more often than every four years.

Yacht varnish is best suited for regions with high rainfall and high humidity. It provides reliable protection against temperature extremes and moisture. Such a varnish does not fade and prevents the appearance of yellowness on the surface. The tool is distinguished by durability, but when painted, it emits an unpleasant odor.

Using wax or stain is an old tried and true method of painting a house. Wax is a natural and safe product that will not harm the environmental friendliness of a wooden structure. It is deeply absorbed into the material and effectively protects the log walls from dirt and moisture. After waxing, the surface will become translucent with a matte sheen.

Stain is the cheapest and most affordable option for processing a house, both outside and inside. It will also protect the tree from pests and fungus, while maintaining the pattern and color of the logs. But after staining, it is imperative to apply varnish to enhance the properties and increase the life of the material.

In addition to the type of paint or varnish, it is important to choose the right color. You can choose transparent compositions to preserve the structure and color of the log, choose a darker or lighter shade, a matte or glossy finish. In addition, today there are also means for painting a wooden house with a color that has nothing to do with the color of the wood.

You can paint the house in purple, green, red and any other colors. It all depends on your preferences. Designers recommend using warm shades in the northern latitudes and cold regions of the country. And in warm regions, on the contrary, apply cold colors.

If you can not find the right materials, seek help from professionals! Experienced experts of the MariSrub company will select high-quality products and calculate the amount of paint, reliably and promptly paint a wooden house, bathhouse or gazebo. Let's find out how to properly paint a wooden house.

How to paint a house

• The initial stage is the preparation of the walls. Remove dust and dirt from the logs, level the surface if necessary;
  Then a primer is applied to the surface. It will protect the walls from mold, blue and fungus. Without a primer, after two years the house will have to be painted again;
• After complete drying of the primer, proceed to painting. Remember that you can only paint dry wood and in dry weather! If you are using oil paints that take a long time to dry, it is desirable that there are no rains in the coming days either. Therefore, before the procedure, check the weather forecast;
• It is better to paint with a roller and a brush, since when using an airbrush it is difficult to get a perfectly even, smooth and dyed coating, especially if you have little experience in painting;
• Before coating, thoroughly stir the paint composition;
• The paint is applied with a roller evenly in two or three layers. A brush is best used for painting hard-to-reach places. Some companies produce special paints with a reinforced protective composition for ends and corners, since these places are most susceptible to the negative effects of moisture;
• Apply each new layer only on the dried previous layer. This takes 3-4 hours; mix the composition of the paintwork agent periodically;
• The last layer of paint is applied from top to bottom in a thin layer;
• At the end, the paint can be coated with a transparent varnish. This will fix the result, increase the life of the coating and better protect the wood. But you can get by with just one color.

How to paint an old house

Remember to renew the paint at intervals depending on the type of paint or varnish. Before painting, it is important to carefully prepare the old house for the procedure. When repainting, experts recommend using the same type of product that was previously used.

After purchasing the necessary materials, the old paint coating is removed from the surface of the logs and dirt is removed. The mold is removed with a special solution and the damaged areas are additionally treated with an alkaline detergent. Old, crooked and rotten boards are best replaced with new ones.

It so happened that the first available paintwork materials are chosen to cover wooden facades, while paints for wood have completely different properties. Today we will tell you how to make the right choice of paint or varnish when it comes to the exterior of a wooden house.

It so happened that the first available paintwork materials are chosen to cover wooden facades, while paints for wood have completely different properties. Today we will tell you how to make the right choice of paint or varnish when it comes to the exterior of a wooden house.

The main functions of the paintwork

Why do you need to paint a tree at all? The answer, at first glance, is quite obvious: to extend the life of wood, to provide it with additional protection. This is really the main, but not the only function of paints and varnishes for wood, in addition, you need to understand what harmful factors the coating will have to deal with.

The most important indicator for any facade paint is weather resistance. We are talking about the ability of the coating to resist moisture absorption and maintain integrity under the influence of chemically aggressive substances dissolved in rainwater. Sunlight resistance is also important: transparent compounds that preserve the woody texture should contain a UV filter to prevent darkening of the wood, and opaque ones just keep the color of the coating as long as possible.

Paint or varnish should also contribute to asepsis. As a rule, this is achieved by protecting the tree from getting wet, however, many coatings have additional additives that prevent the development of destructive microflora. Do not forget about insect pests: high-quality paint covers the wood with a hard shell that the bark beetle is not able to gnaw through.

Finally, the decorative properties should not be overlooked. The facade is the face of the building and the whole exterior depends on its appearance. Depth and the right choice of color in accordance with the details of the surrounding landscape will provide aesthetic harmony and make the house stand out pleasantly from the surrounding background.

Special properties

Depending on the climate and a number of other environmental conditions, paints may exhibit different performance characteristics. They are determined mainly by the technical properties of the coating and depend on the chemical composition of the coatings.

For different regions, you should choose paint with a certain degree of frost resistance. The material must retain a certain amount of elasticity at low temperatures so that the coating does not crack. No less important is the ability to endure high temperatures without irreversible changes in the structure of the coating, because on a hot day the wall of the building illuminated by the sun can warm up to 70 ° C.

You also need to remember the ability of the paint to securely adhere to the base. Most materials, even from a low price category, have good adhesion to bare wood, but the situation changes radically if the wood is already coated with some kind of compound. To avoid the exhausting process of cleaning the facade, you should choose the right composition so that the paint or varnish base does not conflict with the existing coating.

The ability of paint to withstand mechanical stress should not be overlooked. It seems that this indicator is not important for the facade, however, the dust contained in the air acts as an abrasive and gradually thins the upper glossy layer, due to which the coating loses its resistance to moisture, sunlight and biological erosion over time.

Which paint base to choose

Almost all paints and varnishes consist of a base, a solvent and a coloring pigment with a set of additives. And if the appearance and some special properties depend on the last components, then the main characteristics of the paint are determined precisely by the base, which can be of three types.

Water-soluble acrylic paints are the lightest type of coatings, they are not able to withstand the destructive effects of the natural environment for a long time. Therefore, they are usually used with the expectation of regular renewal, or if the wood itself is stabilized and does not need protection. The advantage of acrylic paints is ease of application and environmental friendliness, as well as the ability to easily form an individual shade on your own.

Paints based on synthetic resins - glyptal, pentaphthalic and others - are called alkyd enamels. Their main difference is that they create a durable glossy film on the surface of the coating, which, unlike the film of acrylic paints, is an impenetrable barrier: it does not let water through and limits the base of the coating from chemical reaction with atmospheric gases.

Not all alkyd enamels have high weather resistance, but it is this type of paint that provides the highest degree of wood protection. Often this group includes polymer-based varnishes and paints, but not because of chemical affinity, but because of the similarity in performance.

The third type of base includes stains, which are designed to give the wood a certain color and act as an impregnation that protects against bacteriological damage. Mordants do not form a film, and therefore are not able to protect the tree from getting wet and aggressive chemical attack. For this reason, they are used only if they are subsequently opened with varnish, usually transparent.

Color, gloss and transparency

The choice of coatings for finishing wooden facades, as a rule, is carried out in order to give the building an exceptional appearance. The success of the decision largely depends on the understanding of the basic principles of working with wood, as well as on your own taste.

For the facade, paints of bright saturated colors are very rarely suitable. On the contrary, the most beneficial will be the choice of a calm natural color. If the house is located in a dense building, it is better to give preference to soft pastel colors. For houses located near water bodies, variations of blue and green are well suited, but always muted gray.

Buildings located in the natural environment, for example, with a high density of green spaces, as a rule, try to highlight, painting in colors from sulfur and mustard to dark brown. If natural stone appears in abundance in the surrounding landscape, red-brown tones, as well as deep greens and almost all light shades, work well.

The paint does not have to have a high density of pigmentation. Some enamels allow a partial manifestation of the texture, which is very good for houses whose facade is finished with quality lumber with a minimum of defects.

If the emphasis is on the natural naturalness of the building, it is better to give preference to tinted and transparent varnishes. At the same time, it should be remembered that the more transparent the coating is used, the better the wood should be and the more careful its processing should be carried out before varnishing.

All facade paints differ in the degree of gloss, which must be chosen taking into account two circumstances. The first is the norm of natural light: more shiny coatings look better in shading, while a house with matte paint will not glare too much in direct sunlight. It should also be taken into account that the higher the degree of gloss, the smoother the film is created on the surface upon drying, which means that the protective properties of the coating will be higher.

Consumption and application methods

Paints and varnishes differ significantly in viscosity and hiding power, which limits the choice of how they are applied. For example, the so-called film-forming impregnations can only be applied with a brush, which is extremely inconvenient when finishing surfaces with a large area or when working at height.

Alkyd enamels and varnishes are the most versatile in this regard; when working with them, it is allowed to use a roller or spray gun. Acceptable application methods are determined by the corresponding pictograms on the label. When coating wooden facades, it is optimal to work with a roller: coatings that allow this method of application significantly benefit in the speed of work without increasing consumption.

The total amount of paint for finishing the facade is determined by the consumption rates declared by the manufacturer, the surface area and the number of layers. Be sure to take into account that the consumption when painting rough and smooth surfaces can differ by 1.5–2 times.

Also, when working with a spray gun, it is necessary to purchase paintwork materials with a margin of about 20–25%. Of no small importance are the drying speed of the paint before applying the next layer and the permissible temperature regime - these parameters must be taken into account when planning painting work.

Conclusion

The nomenclature of modern paints and varnishes is organized in such a way that a specific chemical composition and any quantitative expression of the main properties are not indicated for each individual product. This is done not only to keep a trade secret, but also to make it easier for the buyer to choose.

Therefore, when buying paint for your wooden facade, the most correct approach would be to be guided by general ideas about the behavior of a particular type of paint, as well as assign the responsibility for selecting paintwork materials to consultants. In this case, you only need to indicate the type of surface and type of wood, the presence or absence of any coating, the region, special operating conditions, the desired service life and additional wishes.

Please note that not only paints are used to protect wooden surfaces. The manufacturer will definitely recommend a suitable primer and protective impregnation. If high demands are made on the facade in terms of durability and quality of appearance, such recommendations should not be neglected.

As you know, facade paints and varnishes not only decorate wooden walls, but also protect them from insects, ultraviolet radiation, winds, and temperature extremes.

And what will protect the paint itself from unwanted influences? How to be sure that on such a beautiful facade, as in the title photo, the coating will not peel off and will not fall off with petals after some two or three years?

About what paint for wooden facades, taking into account our climate, is the best option, and will be discussed in this article.

Something, but manufacturers know how to advertise their product. Whatever paint you take, the instructions on the package say that it forms an elastic film that ideally protects the wood from all types of atmospheric influences, and is resistant to changes in temperature and humidity. In fact, this super-resistant film cracks after two winters, and the walls become not very attractive. Oddly enough, most often this happens with paints from eminent European manufacturers - but, of course, not all. Is it because of the low quality of their products?

Note! The thing is that in countries with a warm climate there is simply no way to test the paint for frost resistance, since this very frost simply does not happen there. Therefore, experts advise: "If we take imported paint, then Swedish or Finnish, but not from the manufacturers of the Mediterranean countries: Italy, Spain, Greece."

We note right away that paints in which white spirit, turpentine, drying oil are present do not behave very well in the cold. Basically, these are alkyd and oil formulations. Manufacturers of alkyd primers and enamels claim that they are resistant to temperatures ranging from -50 to +120 degrees, but they do not guarantee that the coating will last more than three years.

Oil paints do not even withstand this, and the only criterion for their choice by the buyer was and remains a low price. Yes, it is understandable: if a person, for example, needs to paint a modest country house, he does not want to bear the big expenses for this. Repainting a small building with your own hands is also not difficult. And then, this paint still has some advantages, so let's talk about it in more detail.

Characteristics of oil paints

Oil-based paints, which our chemical industry produces today, differ in characteristics and color range from Soviet-style paints, like heaven and earth.

• Their durability depends on the mass fraction film-forming components, which in a good paint should not be lower than 26%. It is these substances that contribute to the creation of an impermeable film when applying oil coatings to the surface, and the higher their percentage, the longer the coating will last. You just need to keep in mind that too high their content reduces the shelf life of the paint after depressurization of the container. When air gets into a can, the paint turns into a thick lump in a few hours, which can no longer be brought to a working consistency with any solvent.

• An important parameter of oil compositions is such an indicator as volatile matter. In qualitative variants, their number should not exceed 10%. It is precisely because of volatile substances that have a pungent odor and are also toxic that oil paint is practically not used today for interior decoration. But when working on the street, this is not so relevant.

TO disadvantages of oil paints and varnishes, we can also attribute the fact that it takes the most time to dry them - at least two days.

The hardening time of the film, as well as the fluidity of the paint, depends on the level of its viscosity. In a quality material, it should vary between 60-135 units. But the hardness of the coating formed can be considered an undoubted advantage, since it depends on this how long the paint will last on the facade.

The nuances of the use of oil-based coatings

Before applying the oil coating, the walls should be primed with the same paint, but diluted with drying oil to a liquid state. In the process of such processing, the wood is saturated, and the paint consumption for the finish coat will not be so large.

Believe me, the right approach to painting work will allow you to get an excellent result that will please the eye for at least six years.

Water dispersions

Best of all, as a paint for the facades of a wooden house, water-soluble paints have proven themselves. This is a large group of water-dispersion paints, which occupy a leading position in the team of paints and varnishes. Many of them are universal, and can be used both for interior work (see), and for painting facades, which the consumer must be informed about on the label.

So:

• The simplest option is compositions based on polyvinyl acetate, as well as butadiene styrene, which we used to call water-based paint. But they are not suitable for outdoor decoration, as they are highly susceptible to ultraviolet radiation and moisture. But the paints of the new generation, made on the basis of polymer resins, are completely devoid of these shortcomings.

• All types of water-dispersion paints are united only by the technology in which an emulsion is obtained from two immiscible substances. In this case, one of these substances is water, and the other is PVA, butadiene styrene, acrylic copolymers, latex, silicone. A suspension of these substances, the molecules of which are distributed in water, is called a dispersion - it is they who give the emulsion certain properties.
• Water-based paints work quite differently than oil-based paints. The dispersion coating polymerizes upon drying, which is akin to the setting of cement or gypsum mortars. Being in a plastic state, the emulsion is easily diluted with water, but when the film seizes, it becomes resistant to moisture. Accordingly, liquid paint is afraid of low temperatures, but the finished coating is not.
• The list of polymers that act as a dispersion in emulsion paints is quite wide, but acrylate compositions are the most popular. They are distinguished by stability, low price, long shelf life. And they are best tolerated by temperature fluctuations and exposure to sunlight.

• In addition to the water-polymer combination, fillers in the form of talc, cellulose or chalk are added to dispersion paints, which give it the desired density.
• For whiteness, additives such as zinc white are used, as well as a substance called titanium dioxide. Water-soluble paints are produced only in white, and are tinted immediately before starting work. How this is done, you will be prompted by the video in this article, or articles directly devoted to this topic. Let's just say that it is not at all necessary to do it yourself, since in every specialized store you will be offered a computer tinting service, in which you choose the desired shade from fan catalogs.

Tinted paints, or rather, coatings created with their help, do not differ in too bright and rich shades, since the paint can only accept a certain percentage of pigment. If you really need to make a bright accent in the finish, then for this you can use tinting compounds in their pure form.

What to consider when applying

As for the durability of the coating, it, as in the case of any other type of coating, is provided not only by the paint itself, but also by the quality of surface preparation for its application. Everything that was said about the preparatory work in the previous chapter is relevant in this case.

• The only thing, when using water-dispersion paints, the walls need to be primed differently. Since wood, first of all, needs biocidal protection, it is treated with special primers before painting. There are bioprotective complexes with a wide spectrum of action on sale - they not only improve the adhesion of paint to wood, but also act as an antiseptic.

• Similar primers, one of the variants of which you see above, are recommended for protecting structural and facing elements made of wood, as well as windows, fences, and small architectural forms before painting. In this case, not only water-dispersion, but also alkyd paint can be used, as well as all kinds of azures and impregnations, which we will discuss later.

Note! Note that not every antiseptic can serve as a primer - you need to pay special attention to this when buying. If a conventional flame retardant composition was used, then an acrylic primer must be applied on top of it before painting.

Colored impregnations

If we continue the topic of wood impregnations, then one cannot fail to note such a type of finishing compositions as tinted antiseptics.

• They can be glazing, that is, give the coating a shade, while maintaining transparency, and leaving the natural pattern of the tree in sight.
• In another version, colored impregnations create an opaque covering layer that completely covers the wood texture.

Both those and other compounds are used as "two in one":

• and for wood preservative,
• and to give it a certain tone.

In their composition, they are very similar to varnishes, only very diluted. The most popular are translucent impregnations, as they emphasize the texture of the tree.

In order for them to acquire the functions of an antiseptic, manufacturers include fungicides in colored primers that prevent the growth of fungi. Alkyd resins and natural oils are used as additives, which provide the soil with a water-repellent effect.

Depending on the base, tinting impregnations for wood can be water-soluble, like the paints discussed above. They are quite economical, as they are consumed within 70g / m2. Such compositions are applied to dry wood, and preferably, immediately after the walls have been erected. The coating dries on average for about half a day, at normal humidity and temperature close to room temperature.

The color range of tinted impregnations is not very wide, as it represents only the shades inherent in natural wood. The compositions of many tints include wax microcomponents, which perfectly protect the painted surface from fading, cracking, and give it a noble look.

Choice of paint on wood

Paint for a wooden facade is designed to solve two important tasks: to protect the facade and to provide an aesthetically attractive appearance to the building.

Attention: If the tree is not painted in time, it will begin to crack. This happens under the influence of ultraviolet radiation: it breaks down the wood, which paves the way for the spread of microbes that affect it.

When choosing a paint, you should pay attention to the following points:

• Its composition, on which the final result depends. Carefully study the incoming components and their ratio: fillers, pigments, binders.
• Compliance of the selected paint with the type of surface, the material of its manufacture.
• Consider the technical characteristics of the enamel. Choose the type that is best suited for your climatic region, weather conditions.

To determine the type of paint will help classification according to the following criteria:

• binder used. Based on this, the paint is: oil, alkyd, acrylic, silicone.
• The type of solvent subdivides enamels into: water-borne and solvent-based.
• Appointment. Paint is construction, industrial, artistic.
• Gloss degree. The coating looks glossy, shiny, semi-glossy, semi-matte, matte.
• The material from which the treated surface is made. It can be paint for wood, metal (see photo). Types of paints for metal: which one to choose), concrete and other surfaces.

Coloring technology

Facade paint for outdoor woodwork is applied according to certain rules. The appearance and durability of the coating will depend on this.

Attention: An important point: it is recommended to paint a wooden facade at an air temperature of at least + 5 and a relative humidity of at least 80%.

We break the whole process into successive steps:

1. Let's prepare the necessary material and tools: paint, a wide and beveled brush, a narrow roller.
2. Clean the work surface from dust, dirt, cobwebs.
3. We use a primer to process the facade. The lower part should be well lubricated, since it is here that the degree of exposure to moisture is high.
4. To protect the wooden surface as much as possible, experts advise applying an additional layer of antiseptic. This composition prevents the appearance of mold, various fungi.
5. If you plan to use a transparent antiseptic, then it is worth excluding the use of a special primer to protect metal fasteners, as it will shine through the glazing solution.
6. For the primer, we will use a brush in the work.
7. We give the protective solution time to dry completely, usually several days. Then we start painting.
8. Alkyd or oil paint works well for the last finishing coat. This choice depends on the type of wood and the preferences of the owner.

Regardless of the choice of the type of dye, it can be Finnish facade paints for wood and wood plastic, first of all, make a high-quality base. Look at the photo, select the desired color and do everything slowly and efficiently.

A wooden house needs an exterior finish. Every professional builder will agree with this opinion. In addition to decorative functions, the finish also has protective ones: the wooden structure is exposed to moisture, ultraviolet radiation, and pests. For protection and decoration, there are many materials that are almost equally in demand by owners and builders, but paint is often preferable to other options.

Acceptable Choice

Painting wooden facade elements is a budget option. In terms of mechanical, fire-fighting properties, it is inferior to porcelain stoneware or brick, but with the money saved when purchasing the material, it will be possible to buy flame retardants, thanks to which the tree will not be combustible for decades.

A responsible decision is to find how to paint the outside of a wooden house. Manufacturers offer many items for external woodworking, but only a few are relevant. The choice is based on:

• building materials (timber, blockhouse, log, lining, chipboard and others);
• climatic zone;
• previous finish;
• the amount of funds for repairs.

It is preferable to navigate to well-known brands- Tikkurila, Finncolor, Beckers, Optimist, purchasing in time-tested and customer reviews of retail chains or online stores. There are many fakes on the market: saving a few tens of rubles, you risk ruining your house and losing money, because it is difficult and expensive to remake low-quality paint.

Helpful Hints:

What is used

Manufacturers offer different paints and varnishes. Resistant and rough compositions - an option for painting a wooden house outside. Facade paints differ in the composition of the film-forming components. The type of solvent, the possibility of tinting, and other parameters depend on them.

Various antiseptics

Antiseptic varnishes there are glazing (transparent) and covering (they are not transparent). The first type retains the natural color, it emphasizes the wood texture. The second will achieve the desired shade. Means penetrate deeply, protect the tree from rotting, mold, and the negative effects of moisture. Coating compositions serve 6-7 years, glazing varnish needs to be updated every 4-5 years. For surface treatment, antiseptic impregnations are often used, which can also be called paints.

Antiseptics are convenient in covering facades made of planed or polished wood valuable varieties with a pronounced pattern. The compositions dry quickly, for full protection you need to cover the surface with two layers. Only fresh wood can be processed.

Antiseptic impregnation is applied every 2-3 years. There are expensive tools that allow you to make updates once every 5-6 years, belonging to the category of azures or colored impregnations. Together with the protective function, they perform a decorative function. Many products contain substances that delay ultraviolet, so that the tree retains its color.

Acrylic products

These are emulsions, dispersions, water-soluble products. Basis - acrylic resins or acrylic copolymers. The composition may contain artificial or natural rubbers, antiseptics, fungicides. A white or transparent base has a different degree of gloss, it can be matte, glossy or semi-gloss.

Acrylic paints can contain pigments and dyes, thanks to which the painting of the house from the outside will turn out to be of any color, shade. In some catalogs of dyes, up to 20 thousand options are presented. When buying paint, it is preferable to opt for a pigment from the range of colors from the same manufacturer.

Manufacturers do not disclose the chemical composition of the funds, therefore, reactions between products of different brands are possible. When mixing products of different brands, the paint dries for a long time, will bubble, and quickly lose color. To avoid unpleasant situations, check the options for compatibility before buying. It is better to do tinting in the store, it is especially convenient to do this in a tinting machine.

Advantages:

• large color spectrum;
• excellent adhesion to a wooden surface;
• without smell;
• not combustible;
• eco-friendly, hypoallergenic.

Of the minuses, one can note only their high cost. when compared with the cost of alkyd and oil.

Acrylic paints are most in demand among residents of suburban households. Products are best suited for coating natural wood: they are safe. The paints allow the wood to “breathe”, and good air exchange is obtained. An elastic, dense coating is created that protects the wood from moisture, cracking, and fungus. You need to update the painting every 8-10 years.

Alkyd paints

Compounds have been used to treat wood flooring for many years. Created on the basis of polycondensation resins, united under the name "alkyd", the products are distinguished by low production costs, excellent covering ability, and a noticeable level of adhesion to wood. Suitable for painting polished, planed, sawn wood, logs without bark.

Alkyd paints form a dense, durable, elastic film that responds well to the temperature movements of the tree: it does not crack during drying, thermal expansion or other dimensional changes. When coated in 2 layers, the film is waterproof and only slightly vapor permeable. Only dry wood is covered with alkyd paints.

Manufacturers sometimes include antiseptics, flame retardants in the composition of the products. There is information about the presence of such in the instructions for the paint. In the absence of components, the surface is treated before painting. This will increase the cost of painting, but the life of the coating and the structure itself will increase several times.

Alkyd paints are produced in a fixed color spectrum, but it is not difficult to paint a wooden house in the desired shade: the funds are mixed in a certain proportion. The quality of the finish is unchanged. But best for mixing products of one manufacturer.

Leading manufacturers offer colorless alkyd paints. They are tinted in the same way as acrylic. This is convenient, especially when applying the product to a new wooden surface, when looking for an option that will make the house stand out from neighboring buildings, even those built according to the same project. This situation happens in cottage settlements.

Alkyd paints - a competitor in quality to acrylic paints. They lose money only in terms of fire safety during storage and operation. Compliance with strict rules of conduct with open fire, heating devices will be required. As a result, the layer becomes low-flammable, but due to the rapid drying, the agent does not have time to be deeply absorbed inside, this negatively affects the duration of operation. Alkyd paints are frost-resistant: they tolerate temperatures below -30 0 С.

Oil paints

They are well absorbed, penetrate deeply, effectively protect wooden walls from dirt and moisture. But the funds are not very in demand due to the long drying time. After a while, the painted wood will change color, sometimes yellow spots become noticeable on the surface. To avoid such a situation, the walls are repainted every 2-3 years.

For a long time, oil paints, which can be diluted with drying oil or other natural oils, were competitors to alkyd paints. But now many manufacturers are abandoning them because of the difficulty in application, the imperfect characteristics of the finish coating. But despite the shortcomings, such paints are a budget option. After application to a wooden surface, the paint is well absorbed, forming a weather-resistant coating.

Additional options

In addition to the type of coating, it is important to choose a color. Transparent compositions will allow you to preserve the structure, color of the tree, choose a dark or light shade, matting / glossy shine. There are products for painting a house made of wood with colors that have nothing to do with the color of the wood.

How to paint old and new houses

For painting an old building, the recommendation is as follows: if the layer holds well, there are no cracks, no areas of peeling of the film are visible, then the same type of paint is used as before. Alkyd paint can be applied over oil paint: their properties are combined. Acrylic ones are not suitable, but some manufacturers allow this contact.

The type of old paint is determined by the appearance of the coating. Acrylic cracks along the grain of the wood. Oil cracks in the form of a mesh. If the surface is covered with a glossy film of a glazing antiseptic, then painting is done with an antiseptic, oil or alkyd paints. Before repainting with acrylic paint, the old antiseptic film is removed to the wood. Preparation for painting:

1. the surface is cleaned with a metal brush to wood, the facade is washed with water;
2. mold is removed by special means;
3. the wood is treated with an alkaline detergent;
4. surfaces are ground (if necessary).

After preparing the surface, painting proceeds in stages, as for a new building: priming, applying paints and varnishes. Do I need to remove the old layer of paint? Thin, without blisters, cracks is processed with sandpaper. The old thick, flaky, multi-part layer is removed.
