How to paint a house with old paint. Tips on what paint is best to paint a wooden house outside

Paying attention to the exterior of the house, we face the widest choice. Here you have the opportunity to use a brick facade, and hang various panels on the walls, and apply a plaster composition suitable for outside work. But the most convenient way to give the appearance of the house and adjoining buildings is to paint it. True, this process is somewhat different from similar work carried out indoors.

• Paint is a public material. In addition, products are now sold on the market that are specially created for such a process as exterior decoration;
• Applying paint is a relatively simple process that does not require professional knowledge. At the same time, there are spray guns that significantly increase the speed of work and the quality of applying the composition;
• There are many ways to decorate your home. The variety of appearance of facade paints is huge, ranging from standard colors to such an effect as ivory and other surfaces (mainly this can be achieved through tinting).

What criteria should paint for facades meet?

First of all, the economic factor is important. When painting a facade, we sometimes need to cover a huge area with material, and therefore expensive paint will make the work budget very solid and not accessible to everyone. The second factor is the ability to protect the wood of the walls from external influences. The paint with which the exterior finish is carried out must withstand temperature extremes, precipitation (while having good vapor permeability), solar ultraviolet radiation and other natural influences.

Considering the main types of paints for exterior work, it can be noted that water-based silicate or silicone paints will be an ideal solution for painting facades. On the market, this paint and varnish product is known by the name "water-dispersion paints". They meet all the above requirements, and also dry quickly and are quite inexpensive.

As for alkyd enamels or PVA-based paints, they, as a rule, are not used in exterior decoration, but are more intended for interior work. And even then there they are very strongly pressed by water-dispersion compositions, such as acrylic paints.

Important! Do not use oil paints to paint the exterior walls of your home. These paints and varnishes create a layer on the surface that has an extremely low vapor permeability. This is especially important in the case of wooden walls, which must "breathe". The steam coming from inside will simply destroy the paint in just a few years, and the work will have to be redone.

Paint tinting for outdoor work and design selection

Water-dispersion paints can be found already in ready-made colors, but most often such compositions are sold in white form. And this gives us the opportunity to choose colors using tinting.

Important! Colors for paint are best selected on an inorganic basis, as they have the ability not to lose color saturation with prolonged exposure to ultraviolet radiation. In other words, facades will retain their attractive appearance for a longer period.

As for colors, experts do not recommend getting carried away with too bright and non-standard colors. The priority is natural tones, calm shades like the same ivory or coffee with milk. At the same time, it is possible to decorate the facade both in a single-color version, and using various methods of highlighting details, such as joining elements of logs in wooden houses.

Idea! Using paint, you can create half-timbered walls. These are frame houses typical of Germany or the northern part of Europe. It is easy to recognize them - the walls seem to be drawn into rectangles with the addition of diagonal stripes. Typically, the stripes are highlighted in a darker color while the background remains light.

Preparing the wall for painting

• First of all, it is necessary to thoroughly clean the wall from dirt, dust, moss and other unnecessary details. This is true, first of all, for old houses, where, before painting, we will also have to remove the previous finish. But even in the course of building a new house, the camps are also polluted, so it is better to clean them;
• Further actions depend on which wall will be painted. If this is a wooden house, which happens most often, then you need to take a grinder and carefully process the wall. In this way, we will not only improve the appearance, but create a better adhesion. Concrete or brick walls often need leveling. In the case of a brick, it is possible to trim the protruding mortar, and cover the concrete surfaces with a plaster composition;
• Further, wooden walls are usually coated with antiseptic compounds in order to protect them from the formation of fungus and mold. It is necessary to apply an antiseptic with longitudinal movements, especially carefully processing the joints, since it is there that water accumulates most of all. At the final stage, both wooden and concrete walls must be coated with primers for a better application of a layer of paint. Metal structural elements should be especially well primed, since the composition will also resist corrosion.

Important! For deeper color. You can also tint the primer in the same shade that was chosen for the paint.

It is impossible to work on painting at low temperatures and high humidity, as well as under precipitation. At the same time, too much dryness and direct exposure to sunlight are also not acceptable conditions, since the paint dries too quickly, and this can cause cracks. The ideal conditions are cloudy, but at the same time dry and calm weather.

As for which tool to use in your work, you can answer with confidence - you can paint in any way convenient for you. With a roller it is more efficient to process large surfaces without joints. However, it is the joints that are so characteristic of concrete walls that are much better painted over with a brush. Moreover, if possible, then you can use the spray gun, especially since it can be rented for a while without spending money on buying a tool for one-time work.

What paint to paint the house?

To choose the right paint, read the previous page for painting your house outside.

It is quite possible to do the painting of the facade on your own, you only need time, knowledge and patience.

There is always information on paint consumption on the paint packaging. Usually indicate the specific consumption of facade paint - the number of liters (kg) that will need to be spent for painting 1 m 2 facade in one layer, l/m2.

Sometimes facade paint packages indicate the reciprocal of the consumption - the surface area that can be painted with 1 liter of paint, m 2 /l.

Usually indicate paint consumption in a certain interval, for example like this: consumption 0.1 - 0.25 l/m2. Here, a lower consumption value is for smooth primed surfaces, and a larger value is for rough, textured, unprimed facades.

On the websites of paint manufacturers and sellers, you can find calculators for calculating the amount of paint chosen depending on the area of ​​the facade of the house to be painted, on the number of layers and the roughness of the surface to be painted. Facade paint is usually applied in two layers.

To paint a house outside, the amount of paint is determined by multiplying the area of ​​​​the surface to be painted - m 2, specific consumption - l/m2, number of layers - 2, safety factor - 1.1. A safety factor of 10% is necessary to avoid an unpleasant situation when there is almost not enough paint at the end of the work.

How to prepare the walls of the house for painting?

The quality and durability of painting the outside of the house to a very large extent depends on the proper preparation of the wall surface.

The base on which the paint will be applied must be dense, durable and primed.

Preparation for painting the old walls of the house

Improving the condition of the base is usually always necessary before painting the old walls of the house.

Old wall before painting must be cleaned of dust, mold, moss and easily peeling layers of old coatings. To do this, it is best to wash the wall with a pressure washer, for example, an automobile one. Or you can wipe the entire surface of the wall with a stiff brush, but this option is more laborious. It is better to use both methods, after washing, brush only the places of intense pollution.

Places of accumulation of mold, moss after their removal must be treated with a liquid bioprotective preparation. Otherwise, parts of these biological substances may remain in the thickness of the wall covering, which will quickly grow through the new paint.

Then the plastered surfaces are repaired, cracks are repaired, places with peeling plaster are repaired. Old paint on the facade should not flake off and dust. Places with peeling paint are cleaned, primed and covered with an additional layer of new paint.

If the old paint is damaged over a large area, then it is better to remove it from the entire surface of the wall. It is convenient to use a sandblaster to remove old paint.

How to determine the strength of the surface of the painted wall?

For this a fairly large piece of transparent stationery tape is glued to the wall and a minute later, with a sharp movement, they tear it off the wall. If, along with adhesive tape, pieces of the base did not come off the wall, then such a wall can be primed and painted. Otherwise, the wall surface should be cleaned by removing the old paint.

Preparation for painting the facade of a new house

The plastered facades of new houses are quite durable. Preparing the facade for painting a new house outside comes down to the following steps:

1. It is necessary to dry the freshly plastered facade for at least 30 - 60 days. The wall must be completely dry.
2. Apply a primer to the wall of the house.

Non-plastered facades made of sand-lime bricks can be coated with a special colorless protective compound, or simply painted with facade paint. In any case, the surface of the wall is primed.

Facades made of facing ceramic bricks usually not dyed.

New walls made of ordinary ceramic bricks it is better to paint in the first two years, before efflorescence appears on them.

Priming the walls of the house outside

The primer allows:

• strengthen the dusty base;
• increase the adhesion (adhesion) of the paint to the base;
• reduce the water absorption of the coating;
• reduce the consumption of facade paint.

Facade paint spreads more easily over the primed surface, and consumption is markedly reduced..

The quality of painting the facade of the house can be improved if tint the primer to match close to the color of facade paint.

Sometimes as a primer use facade paint diluted with water in a ratio of 1:1.

The primer is applied to the wall surface in the same way as the paint. Before painting, the primer must be allowed to dry completely for at least a day.

How long does the paint dry?

Most facade paints dry completely and create a durable coating. after 24 hours after applying to the wall.

The second coat of paint, as a rule, can be applied earlier, without waiting for complete drying of the first coat. Information about the duration of the period after which a second coat of paint can be applied is contained on the paint package.

How to apply paint?

Facades are most often painted with a roller, brush or spray gun.

The choice of tool is determined by the consistency (viscosity) of the paint, the texture of the surface to be painted and the qualifications of the workers.

Walls with a smooth surface paint with a brush or roller with a short nap. It is more convenient and faster to paint with a roller than with a brush, besides, less paint is consumed.

When painting walls with textured surface or directly on the brick, use a wide brush with long bristles.

The spray gun can paint walls of any texture both smooth and embossed. Painting a house with an airbrush requires higher qualifications and experience from the performers with this paint sprayer. It is necessary to choose the correct viscosity of the paint, select the nozzles for the sprayer of the apparatus. It also requires a practical skill in uniformly applying paint to the surface of the wall. It is better to entrust the painting of the house with an airbrush to specialists.

In case of using special high-viscosity textured paints with filler, for applying paint to the facade, in addition to the above tools, they also use a spatula.

Painting the house outside

Painting the house outside can be done on your own by following these guidelines:

1. The work on painting the facade must be planned, having read the weather forecast. On rainy, windy days or at temperatures below +5 about C it is better not to paint the facade.
2. Surfaces to be painted must be be sure to prime. To apply a primer to a wall, use the same methods as for applying paint (see above).
3. Before starting work, all non-painted parts of the facade (windows, doors, slopes, plinth, blind area, etc.) are protected with plastic wrap.
4. Painting work is carried out in dry weather in the absence of strong winds. The outside air temperature must be within the operating range indicated on the exterior paint package. Check the weather forecast before starting work.
5. To paint the facade at a height, install scaffolding or scaffolding. Paint the facade from the stairs is not convenient and dangerous.
6. A layer of paint is applied to one wall of the house without taking long breaks in work. If part of the wall is painted the next day, then stains will remain on the wall - places with a different shade of paint.
7. The second coat of paint is applied after a break, not earlier than indicated by the manufacturer on the paint package.
8. In order not to wash the roller or brush before each break in work, wrap the tool in a plastic bag - the paint will not dry out.

The paint is distributed by moving the roller or brush in different directions alternately - vertically, horizontally and diagonally.

How to store paints?

Paint packaging should be protected from direct sunlight and frost. The paint should be stored at a temperature of +5 to +25 degrees C in a tightly closed package. Paint stored under these conditions remains usable even after the expiration date printed on the packaging.

If during storage the paint has exfoliated, mix it thoroughly with a mixer - a nozzle on an electric drill, and the paint will again become usable.

What color to paint the facade of the house

When choosing the color of the walls of the facade follow the following basic rules:

1. The color of the walls of the facade of the house should be different from the color of the roof.

2. The color of the paint should be in harmony with the natural and other non-paintable materials used to finish the facade: brick, natural stone, tiles, panels, etc.

3. Various architectural elements on the facade are distinguished by color: the front door, windows, shutters, cornices, cladding, etc.

4. If there is no contrast in the color scheme, the facade, as a rule, looks dull and not attractive.

In the photo, the main color of the wall painting is combined with the color of the natural stone on the facade.

Smaller elements of the facade are highlighted with light beige paint. A warm light tone against the background of a thick dark wall color softens and makes the color scheme pleasing to the eye, successfully decorating the facade.

The color accent on the front facade, as a rule, is placed on the entrance to the house, the front door.

In this photo, the wall of the first floor of the house is made of unpainted clay bricks. The color scheme of the facade of the upper floor was chosen in such a way as to visually reduce its volume and make the lower level more significant.

Facade paint in your city

Construction facade paint for outdoor use

Regular inspection and elimination of any defects will ensure the durability of the facade. After each winter, it is worth checking the condition of the plaster and the paint layer. Here are the basic tips for their maintenance and repair.

The most common are damage caused by deformations of the base of the plaster or paint layer, as well as mechanical damage, and damage associated with leaching of plaster by rainwater in case of leaks. Only after the causes of damage have been eliminated can repair of the damage sites be started.

Well-made decorative thin-layer plasters applied to thermal insulation usually do not require any repair for many years.

Regular inspection of the façade and decontamination are the main means of its maintenance.

Even small leaks, if they are not eliminated for a long time, over time, can lead to significant damage not only to the paint, but also to the plaster layers. If you react quickly, it is enough to restore only the color. It is necessary to eliminate the cause of leaks, let the wall dry and repair.

Green algae on the facade - how to prevent and remove

Green algae on the wall always indicates high humidity, which promotes algae growth.

Houses located near forests and parks, in areas with high humidity (near water bodies), are especially vulnerable to biological pollution. Only the northern and western walls are subject to green invasion. This is due to the fact that the winds from the west blow more often, and the rain falls on the walls from these directions, and the sun is less frequent in these places. Algae and fungus spores thrive on damp surfaces, and on the southern walls, the sun dries out the façade.

Walls with a small degree of contamination are sufficient to be disinfected with a preparation to combat microorganisms, and then washed with water under pressure. If traces of algae remain after disinfection, then it will be necessary to restore the color - paint the facade with paint with biocides.

It should be remembered that the period of active work of most biocides is three to five years. After this time, in areas particularly prone to microbial contamination, the façades must be re-protected by spraying the preparation. I do not know of a means of providing long-term permanent protection against algae.

Wooden houses are quite popular among people who wish to acquire their own home. Such popularity is explained by the fact that wood is an environmentally friendly material and it is easy to process. Due to the thermal insulation properties of wood and the “breathing” structure, it is warm in winter and cool in summer. The house, built of wood, is perfect for living in the city and outside the city. It would be useful to note that very favorable conditions for children are created in a wooden house. However, the tree has one significant disadvantage, which is that the tree quickly ages.

Why does a tree age?

First of all, this is due to the fact that wood is a living material, which, like a person, wears out over time. A felled tree can no longer feed through roots and leaves and, accordingly, cannot resist aging on its own. In addition, wood is affected by various external factors that negatively affect both the appearance of the tree and its properties. Moreover, it is possible to assess the degree of impact of these factors on wood as early as a month after the house is built, since the tree needs a little time to settle down.
Precipitation in the form of snow and rain causes the wood to swell, while drying causes the reverse process. In this regard, cracks appear on the surface of the tree, in which favorable conditions are created for the development of fungus or the appearance of insects.

By the way, if your house is located in a wooded area, then the probability of wood damage by various beetles is very high. Due to insects and fungus, the tree begins to rot and simply crumble. Solar radiation and temperature changes make their “contribution”, reducing the strength of the wood fibers, as well as making it rough and gray.

Features of painting a wooden house

However, like a person, a tree can be protected from the aggressive effects of the environment. For these purposes, you can use various impregnations and varnishes, which significantly increase the life of wood. With their help, you can even make the tree less fire hazardous.

It is also pleasant that many products are made from natural ingredients, which makes them environmentally friendly. Although it already depends on the specific manufacturer. But be that as it may, the easiest and most common way is to paint the tree.

This method will make your home not only protected from the effects of negative external factors, but also transform it. When choosing a paint, it should be borne in mind that there are different types of it. Therefore, not any type of it is suitable for the outer surfaces of a wooden house. But this will be discussed a little lower.

What color to paint the facade?

When a homeowner decides to paint the facade of his wooden house, it is not uncommon to have to struggle with the choice of color, which will be, in a way, the calling card of the house. What color to choose? Whether to use one color or several for the facade, place patterns on the walls of the house or cover it with a solid color - these are just a small part of the questions that homeowners are looking for answers to. In fact, a lot depends on your tastes and the area surrounding the house. Otherwise, there are no restrictions. But nevertheless, some advice should be given on choosing a color so that the house has a more or less aesthetically pleasing look.

Houses located in the southern latitudes are usually painted in cold colors (blue, white, purple, and so on). And those houses that are located in the northern latitudes, as a rule, are painted in warm colors (yellow, green, orange, and so on). This is done in order to highlight the house against the general background, by creating a contrast with the environment. Perhaps, many have seen the colorful houses of the Scandinavian towns and villages covered with snow. Agree that they look amazing. And imagine if the houses in the snowy valley were painted white, then from a distance you might not see them at all.

If you like rigor in design, then gray can serve as a color scheme. However, it should be noted that you should not choose too dark a shade, as it will deprive the house of severity, and make it look like a dark spot where decor elements will not be visible. Those homeowners who want to paint their home but don't want to lose the naturalness of the color can opt for light yellow, light brown, or even dark brown paint. This color will add saturation and not deprive of naturalness. And if you apply the paint in a thin layer, then through it you can even see a woody pattern.

Paint for a new wooden house

As mentioned above, not all paints are suitable for outdoor use. This is due to the fact that the outer surfaces have to be exposed to more stress than the inner surfaces. Accordingly, outdoor paint must have a number of special properties that make it more resistant to environmental influences. Currently, there are two most common types of paints for outdoor woodworking: acrylate and oil. Both of these types are best used together with antiseptic agents, which greatly improve protection.

Acrylic paints have increased resistance to negative factors, and also retain their color and gloss for a long time.

Using this type of coating will allow the "wood" to breathe, so that your home will always be fresh and comfortable. Separately, it is worth mentioning such a property of acrylate paint as elasticity. This property prevents the coating from cracking when the wood swells or shrinks. The average service life of acrylate paints without loss of properties is 8 years. As a rule, after about this period, cosmetic repairs are carried out.

Oil paints are also quite resistant to external influences, but they cannot boast of elasticity and eventually crack more than acrylate paints.

Another disadvantage of this type of paint is that they dry out within a day, and sometimes even longer. However, they are perfectly absorbed into the wood and allow you to get a rich color that will last for a long time (approximately 6 years). Gradually, the surface becomes matte and better reflects the sun's rays, which has a positive effect on protection from ultraviolet radiation.

As for antiseptics, as already mentioned, they improve the protective properties and reliably protect the wood surface from the appearance of rot and mold. The depth of penetration of antiseptics into wood is 4-5 mm, which guarantees reliable protection.

It is worth adding that antiseptics are divided into two types: glazing and covering. Glazing antiseptics should be used when you want to preserve the natural color of the wood, as the liquid is clear. As for coating antiseptics, they are opaque and hide the pattern of the tree, but retain its relief.

Preparing a wooden house for painting

Even a new surface needs to be prepared for painting. Proper preparation of the wood surface will increase adhesion, as well as increase the life of the coating itself.

• It is necessary to clean the surface of dust and dirt with a regular household brush and water.
• If you notice resin on the wood, then it is best to clean it off with a metal spatula. Treat the place where the resin was found with Oksalakka knot varnish.
• Any metal parts that are in the wood, cover with a metal primer Rostex Super. In the future, it is from these areas that you can begin to peel the paint.
• If the wood is damp, then treat it with a building hair dryer. However, do not set the temperature too high, as this can harm the tree. If the wood is damaged by blue, mold or fungus, it must be treated with antiseptics. For example, wood bleach with Fongifluid, Sagus, Senezh Effo, Neomid 500, Homeenpoisto is suitable. Rinse with water after treatment.
• When these works are completed, it is worth waiting one and a half to two weeks before proceeding with staining.

What is the best way to paint wood?

As a tool for painting a wooden house, a wide brush is best suited. You can also use a roller, but it is more suitable for smooth surfaces, for example, for the walls of houses made of timber. If the house is made of logs, then it will simply not be possible to paint over all the seams and corners with a roller.

Another option for painting a wooden surface is to use a spray gun or spray gun. With it, you can evenly cover the entire surface of the house with paint, as well as paint over hard-to-reach places. In addition, it saves paint well. However, not all homeowners on the farm have such a device.

How to paint - paintwork products

If your house has already been painted with oil or oil-based wood impregnation, then when renovating the house, you must use natural wood oil, for example, Werfain Brunoleum.

You can combine multiple shades of oil to give your home a unique color palette. For example, the general facade of the house with light brown tinted oil (Ton-Beitz Verfijn), and the elements are Bruinoleum.

The photo below shows the same paint, but on a different object.

It looks like the use of "garden oil" Garden Naturals.

Read reviews about paints beforehand, since the price of paint Verfijn (Werfain) - Bruinoleum (Bruinoleum) - 380 rubles. And bituminous oil - 324 rubles.

How to paint a new wood surface

In fact, in order to perform this set of works efficiently, you do not need to have any special skills. It is enough to do everything consistently and accurately. Now let's move on to the actual process of painting a new wooden house.

1. At the first stage, the surface of the wood should be completely treated with an antiseptic in order to increase the degree of protection, as well as improve adhesion.
2. The paint should be applied to the surface, so let it dry. It may take from two hours to a day.
3. At this stage, proceed to the direct application of paint. It is important to note that it is best to start painting from the top of the wall, as smudges can form, which will have to be constantly smeared if you start from the bottom.
4. Let the first layer dry and then apply the next layer. In total, you need to make two or three layers.

Painting an old wooden house

Despite the fact that paint protects a wooden house from aggressive environmental influences, over time it also becomes unusable. As a rule, this manifests itself in the loss of former color saturation, cracking and peeling. And such types of damage as the formation of internal cavities are difficult to notice at all. Therefore, it is imperative to update the coverage in a timely manner in order to avoid similar surprises in the future.

It is best to paint the surface of an old house with the same type of paint that was originally used. If you do not know its type, then pay attention to the texture. Acrylic paint is quite thin and somewhat similar to leather. Oil paint has a matte finish when dry and can leave marks on the skin when touched.

You can also conduct a small test to more accurately determine the type of paint. Take a piece of peeling paint and try rolling it into a small roll. If this was not possible, and it crumbled in your hands, then it is definitely oil paint. If the roll turned out to be rolled up, then the house was painted with acrylate paint.

Preparation of the wooden facade

When you have decided on the type of paint that the house was painted with, you can get to work. Before starting work, it is necessary to clean the surface of old paint, dirt and rot. It is impossible to paint over old paint - the coating will be short-lived. It is best to prepare the surface with a wire brush or scraper.

As for rot and mold, it must be removed with a special solution. Alternatively, you can use vinegar, hydrogen peroxide, or even baking soda diluted in water. Once the surface is clean, spray it with water from a spray bottle and let it dry. For better adhesion of paint to wood, you can additionally treat the surface with an alkaline solution.

How to paint a house with old paint

The process of painting an old wood surface is practically the same as painting new wood, so it makes no sense to re-describe the entire process. However, there are a couple of nuances worth mentioning. Old wood should not be painted with a roller, even if its surface is even.

The fact is that due to the constant swelling and shrinkage, cavities that are invisible at first glance, but nevertheless, existing cavities are formed between the fibers. These cavities are quite difficult to fill with paint when applied with a roller. Therefore, it is best to use a brush. Also, more than three coats of paint may be needed to give the surface a cleaner look.

• To get an even color, do not forget to stir the paint.
• It is recommended to apply paint in the longitudinal direction. The same applies to antiseptics.
• Do not paint on a hot day, as the paint may dry too quickly, which is highly undesirable. In this case, it can quickly crack and peel off. It is best to work in warm, calm weather when there are a lot of clouds in the sky.
• If the house is log, then pay special attention to the end parts of the logs, because they are the most vulnerable and moisture accumulates in them. Apply two layers of antiseptic and primer to the ends of the logs. Paint should be in three or four layers.

Competently executed painting of the facade of the building can transform a nondescript wooden house into a beautiful "teremok" that impresses with its artistic style. To form the external appearance of a residential building, a wooden house is painted, the paint for which is selected in strict accordance with the type of material from which the structure was built, and the conditions of use - for painting the house from the outside or from the inside.

Even a small country house is transformed after painting Source indeco.ru

You can paint a wooden house with various types of paints and varnishes (hereinafter referred to as paintwork materials), since the performance characteristics of paints for exterior and interior work are different. The attractiveness of the building and its durability depend on the quality of the painting of the facade of a wooden building.

Causes of wood aging in wooden houses

From time immemorial, wooden houses have been serving people, protecting them from cold, rain and wind. At the same time, the building is exposed to negative environmental influences, leading to the aging of wood and the deterioration of its properties as a building material. The centuries-old practice of operation has determined the approximate period of wear of wooden residential buildings, not exceeding 80-85 years.

The main natural factors that age the natural wood of the facade of buildings are:

direct sunlight, mercilessly drying wood fibers. Dry fibers lose their elasticity and strength, change their position, become sharp. The surface becomes rough, begins to actively absorb sedimentary moisture, burns out and becomes covered with dark spots;

sedimentary moisture, provoking deformation and swelling of the material;

That's what will happen if you don't take care of how to beautifully paint the wooden house outside, the photo below is not the worst option.

An unprotected wooden surface quickly begins to deteriorate. Source lestorg32.ru

temperature changes are the worst enemy of any building material. With a sharp cooling, the moisture that fills the pores of a damp tree freezes, turning into a crystalline state. Ice crystals expand the fibrous structure of the tree until the individual fibers break. When drying, the fibers narrow, which, with repeated cyclic repetition, leads to cracks;

wood that is not protected from moist air is prone to rotting, mold and fungal deposits;

wood-boring insects such as bark beetles, which grind wood and destroy the integrity of the tree structure.

Additional protection of a wooden house when painting

There are plenty of factors that cause wood aging and premature wear at home. To preserve wood in its original natural state, it is necessary to comprehensively protect the surface of wooden walls with special chemical compounds:

flame retardants - to protect against fire;

moisture-repellent agents - to protect against moisture;

antiseptics - to combat fungi, mold and other biological pests;

insecticidal preparations - to combat the invasion of carpenter insects.

Similar formulations are usually sold in standard containers. Source zelmasterplus.ru

A worthy and convenient alternative to the use of protective chemical compounds is painting for the facade of a wooden house, which achieves the same effect, similar to the use of a whole complex of different preparations. At the same time, painting a wooden house from the outside performs a wider range of tasks compared to the monofunctions of each protective solution separately, since, along with maintaining the quality of the wooden facade, the paintwork coating pursues decorative purposes. Using a variety of options for painting a house, you can significantly transform the look of the old facade and the entire wooden structure.

Requirements for paints for a wooden facade

Distinguish paints for internal and external works. Coatings for outdoor use have a wider temperature range of use, they are more moisture resistant. Compositions for painting interiors must be safe for people and pets, have no unpleasant odors, and be highly resistant to abrasion.

Initially, the facade of a wooden house was painted with paints for outdoor use. When the improvement of the facade by painting became popular, paint manufacturers instead of “outer” often began to write “facade” on the packaging. Over time, the second name stuck and began to be used even more often than the original.

Paint "Facade" and "For outdoor work" is one and the same Source karaokerox.ru

The following requirements are imposed on facade paints for wooden houses:

High adhesive qualities in relation to wooden surfaces.

Increased impact resistance and resistance to scratching and chipping, providing mechanical strength of the coating. The presence of increased mechanical wear resistance and resistance to abrasive wear from exposure to wind with dust.

Weather resistance, which consists in the ability of a paintwork coating to resist the destructive effects of bad weather and the environment. Here you can also add the requirement for the chemical inertness of paintwork materials in relation to alkalis and acids formed in areas with a high concentration of exhaust gases.

Hydrophobicity, providing water-repellent properties to protect wood from decay.

Resistant to sudden temperature changes of a cyclic nature.

Light fastness (resistance to ultraviolet radiation).

Good vapor permeability.

Preservation of elasticity after drying, compensating for microdeformations of facade materials during temperature changes.

Low dirt retention, resistance to repeated washing.

The ability to maintain color brightness for a long time.

Able to impregnate the outer layer of wood to a depth of 4-7 mm for full protection against the negative effects of the environment, rot, mold and fungus. The industry produces two types of antiseptics:

coating antiseptics - opaque coatings that completely hide the texture of wood, while maintaining the surface topography;

glazing antiseptics - transparent coatings that preserve the natural pattern of the texture.

Acrylate coatings

They have excellent weather resistance and allow the wood to "breathe". Acrylate coatings do not interfere with natural air exchange through wooden walls. Acrylate paints have high elasticity, which allows the painted layer not to crack when the facade is deformed. In European countries, more than 80% of residential buildings are painted with acrylate coatings. Acrylic paints of different colors are mixed into homogeneous compositions, which makes it possible to obtain a color scheme of any desired color.

Oil paints

prolonged drying of oil coatings, exceeding 24 hours;

after coating with oil paint, the wooden surface becomes matte.

Alkyd coatings

Endowed with water-repellent properties. However, due to the rapid drying (20-30 minutes), the coating penetrates into the wood layers to a shallow depth, so alkyd coatings are short-lived. A distinctive feature of alkyd coatings is the ability to withstand low temperatures below 30 degrees below zero.

It is important! Any paint and varnish covering needs to be updated periodically. Having decided how to paint a wooden house outside, you should know the maximum period during which the applied coating may lose its original appearance and quality:

for antiseptics, the service life is from 5 years for glazing compositions and up to 7 years for coating antiseptics;

for acrylate materials - no more than 8-10 years;

for oil paints - up to 6 years;

for alkyd coatings - up to 7 years.

Optimum selection of coloring composition for the facade

Acquisition of facade paint from leading manufacturers does not yet guarantee high-quality painting of a wooden house. Paint for a wooden house on the outside must comply with the operating conditions of the building and the condition of the surface to be painted. For example, paints made in Spain or Italy are more adapted to the mild climate characteristic of these countries, while paints from Finnish or Swedish brands are designed for harsh winters.

Oil paints are more appropriate when painting the outside of a wooden house over old paintwork, as wooden buildings used to be painted with oil paints, on which modern compositions do not fit well. It should be clearly understood that the determining factor in choosing paintwork materials for repair and restoration work is the type of binder, but not the solvent. Therefore, oil or acrylate paints can be applied to old oil paint or alkyd without any problems, however, only acrylate paint can be applied to an old acrylic-based coating.

Alkyd coating options are characterized by high frost resistance, they continue to perform their functions at frosts below -30 ° C.

Acrylic paints are popular due to their ease of use, they can be diluted with water and applied in any way. When painting, you can get the shade of the desired color yourself. It is enough to purchase white paint as the base composition and special colorants, combining which, they get the desired color shade.

The general progress of the painting of the wooden facade

Painting a wooden house from the outside conditionally takes place in two main stages: preparing a wooden surface for applying paintwork materials and directly applying a paintwork.

Surface preparation

This is an important point that determines how to paint a wooden house with the maximum protective effect. Applying paint to an unprepared wooden surface is highly undesirable, since conditions for good adhesion of paintwork materials will not be provided and the rules for processing wood from negative biological influences will not be observed. Preparation of the surface for painting consists in carrying out the following activities:

if the building is new, then it is enough to clean the wooden surface from dust and dirt with any improvised means.

if it is required to paint the facade of an old building, then the remnants of the old paint and varnish coating are first removed and traces of mold are destroyed;

damaged areas of the wooden surface are repaired, all irregularities are cleaned, cracks are puttied;

nail heads, metal inclusions are coated with a metal primer;

it is desirable to carry out finishing alignment with a primer.

It is important! Upon completion of the preparatory measures, it is recommended to leave the treated surface for several days until it dries completely with the provision of high-quality ventilation.

Application of coatings on the prepared facade surface

It is carried out in the following sequence:

wood is impregnated with a primer antiseptic in order to enhance its protective qualities and improve adhesive ability;

a topcoat is applied, consisting of a layer of primer on wood and several layers of paint, with a time interval that guarantees complete drying of each previous layer.

Painting a new and old surface is carried out in the same sequence, but several nuances should be taken into account:

the facade surface of the old building must be painted with the same type of paintwork that was originally used;

When painting the exterior wooden surfaces of a residential building, it is recommended to "listen" to some advice from experienced craftsmen.

Paint is applied only on a dry surface. When painting in several layers, an interlayer exposure is observed, which is 24 hours for alkyd compositions, and from 2 to 12 hours for water-borne compositions.

LKM is applied in a direction longitudinal with respect to the fibers.

Exterior paint consumption will noticeably decrease if the surface is primed.

Conclusion

The facade of the building is the face of the building. By the appearance of the facade, they judge not only the quality of a residential building, but also the tastes of its owner. Therefore, the coloring of the facade should be attributed to one of the main measures for shaping the appearance of the building and ensuring its readiness for long-term operation.

Why does a tree age?

First you need to figure out why houses made of wood begin to collapse over time. They protect residents from wind, frost and bad weather, while being exposed to negative environmental influences. Despite the fact that wood is a durable material, the following external factors influence the construction:

Wood is a living material subject to aging and wear. It should be noted that the maximum service life of wooden buildings usually does not exceed 85 years. In addition, the tree is prone to fire, so it is better to cover the surface with a refractory compound.

What means are needed to protect the wooden facade:

• water-repellent;
• refractory (flame retardants);
• antiseptics (against pests, mold and mildew plaque);
• insecticidal compounds (against insects).

All these properties combines a special paint for. Most of all, buildings need protection near natural water bodies: lakes, rivers, ponds and streams. Also, an increased concentration of exhaust gases from the nearest route also negatively affects the condition of the wood and will lead to its accelerated aging.

How to choose paint

For exterior facades, special compositions are used, designed for use in contact with wood in the open air. Such pigments are usually not afraid of ultraviolet rays and retain their color and original appearance for a long time. High-quality paint should also protect the tree from rotting and swelling, not letting moisture into the structure of the material.

What functions should a layer of special facade paint perform?

• waterproofing - protection against dampness and water;
• aesthetic - decoration, ennoblement and renovation of the facade of a country house;
• extension of service life - protection of wood fibers from pests and drying out under the action of ultraviolet radiation.

Decorating the house inside and outside are completely different things. External surfaces are much more tested and exposed to the aggressive influence of the external environment: rain, snow, frost, direct sunlight and pressure drops. The video shows how beautiful it is outside (as in the photo of stylishly designed buildings on the Internet), while using well-chosen paint and varnish materials for cladding.

What are the requirements today for "external" paints:

In hardware stores you can find several types of paint and varnish products that differ in properties, composition and external qualities. At the same time, they are all divided into covering (oil, latex (or rubber), acrylic (or acrylate) and alkyd-based) and antiseptic.

Varieties:

The service life of the paintwork is on average from 5.5 to 10 years, while acrylic compounds are considered the most durable. You should carefully monitor the condition of the external walls of the house and carry out periodic painting to update and redecorate the facade.

What other façade options are there:

Many compositions affect the appearance of exterior walls in different ways: some retain the wood structure, while others are able to hide the naturalness of the wooden sheet. The latter include antiseptics of the covering type, which create a dense elastic layer of a protective film on the surface that hides the texture of the wood.

When painting a house, it is important not only to choose the right type of paint and varnish composition, but also the color of the color scheme. Sometimes it can be a combination of several shades, as well as patterns, drawings and prints. In this case, it is important to be guided by both personal taste preferences and landscape features.
