Sooner or later, every owner thinks about how beautiful it is to paint a wooden house outside (below is a photo of a stylishly painted facade). Properly executed painting will transform even the most nondescript house. To form a beautiful appearance of a residential building, the paint should be selected in strict accordance with the material and conditions of use. Indeed, the first impression of guests and neighbors about the dwelling as a whole will depend on what the house will look like from the outside.

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.

An open-standing house by a pond needs more protection than a building in a forest or village

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.

How to choose a color for the facade

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.

What factors will influence the choice and combination of colors in the facade decoration:

Facade decoration is a laborious, but exciting task. Everyone wants to make the face of the building attractive and stand out against the background of surrounding objects. The video tutorial shows how to beautifully paint a wooden house on the outside, as in the photo of design options for stylish facades of modern buildings.

A tree is a living material, so processes characteristic of all living organisms take place in it. Under the influence of time and adverse weather factors (rain, sun, temperature changes), wood begins to age, hurt and collapse. Various microorganisms and insects that settle in the tree and gradually destroy its structure, as well as mold and fungus that form in humid places, also contribute to this negative process. As a result, the wood loses its original appearance, and the house turns into an unsightly gray structure. Painting the grayed walls of a wooden house can solve the problem. How to update aged wood, and what paint is better to paint it, we'll talk about this.

The old wooden structure, unlike the newly built house, has already experienced the negative impact of time, bad weather and other natural factors. Therefore, the building, as a rule, has a very unpleasant appearance: the wood is cracked and darkened, the logs are covered with a network of small cracks, in some places mold and fungus “bloom”. In general, there are all signs of old age and wilting. The best way to update an old building is to paint it.

The difficulty of painting an old wooden house from the outside with your own hands lies in the fact that the paint with which the building was painted has become unusable, it peels off in places, peels off and hangs in pieces. It is impossible to repaint a building in this state without pre-treatment.

If fresh paint is immediately applied on top of all this “beauty”, then nothing good will come of it. A new coating will not save the house from further destruction, but on the contrary, applied to an untreated surface, it can provoke increased crumbling of wood. Therefore, before painting an old wooden house on the outside, it is necessary to carefully prepare and renew the surface.

The first step is to review the entire structure. If, as a result of the inspection, logs that are rotten and severely affected by the fungus are found, they will have to be replaced. If the wood has not yet been destroyed, moldy areas can be saved. In this case, moldy places are treated with an antiseptic.

The darkened surface can be bleached using special bleaching compounds. For the same purposes, ordinary cheap whiteness is suitable, which will provide the same effect as more expensive special equipment. Large and small cracks are sealed with acrylic-based fillers for outdoor use. If the surface is supposed to be painted in the future, putty of any color is suitable, it is better to use products to match the wood under the varnish coating.

The main stages of preparatory work:

1. Old peeling paint is scraped off with a metal brush or spatula. You can also use chemicals designed to clean the surface. The mechanical method is faster, and the chemical one is longer, but more effective. After chemical treatment, the old log building will look like new.
2. An uneven and rough surface is sanded to a good light wood. To do this, use a grinder with a special nozzle. If irregularities remain on the tree after grinding, they are smoothed out with coarse-grained sandpaper.
3. Next, a primer is applied. To protect the wood from the appearance of fungus and mold, it is better to paint with a primer with antiseptic additives. It is advisable to use a primer to match the color of the paint that is supposed to paint the house.

To determine the best way to paint a wooden house, you need to get acquainted with dyes that are suitable for painting the outer walls of old wooden buildings.

There are several types of coloring compositions:

1. Oil paints have very good penetrating power and are perfectly absorbed by the wood. They are also highly resistant to any atmospheric conditions.
2. Acrylate paints form an elastic coating on the surface that does not crack when wood shrinks during seasonal temperature fluctuations. Re-painting will be required for the house no earlier than ten years after the repair.
3. Coating antiseptics reliably protect the tree from various adverse weather phenomena, and also prevent the formation of mold and rot.

The coloring of the old house has its own nuances. For a wooden structure that has not been painted, any of the above compositions can be used. If you want to update a previously painted house, then there are rules. Painting a wooden house on the outside with old paint can only be done with the same coloring composition with which it was painted earlier. On top of the oil paint, you can apply an oil dye, a structure painted with an acrylate composition is re-painted with it.

A different type of paint can be applied to an old painted surface only if the previous colorant is completely removed before re-painting. If you bought a house already painted and do not know what composition it was painted with, you can tear off a small piece of old paint and roll it into a roll. If the old coating is easily folded, most likely the structure is painted with acrylate dye, but if the paint has crumbled, then you have an oil composition.

Only dry wood can be painted, otherwise the paint will curl. Painting is best done in cloudy, but not rainy weather. This is due to the fact that direct sunlight, when it hits a painted surface, contributes to the formation of stains.

Before applying the paint, it must be thoroughly mixed. For coloring, it is better to choose a wide brush with natural or mixed bristles and dense packing. Work begins with the lower crowns of the log house, applying paint only in a horizontal direction to avoid smudges. To get a smooth and beautiful coating, you need to apply two or three layers. Having repainted the house for the first time, you need to wait for the paint to dry completely, and only after that proceed to the next layer.

Mistakes when doing work yourself

A typical mistake when painting an old wooden structure is poor-quality and improper preparation of wood before applying the dye. Some non-professional builders, wanting to repaint an old log house quickly and cheaply, do only a fraction of the necessary prep work, or skip the prep work altogether, which only adds to the cost in the long run. For example, when self-painting, logs are often not sanded, as a result of which the antiseptic cannot penetrate deep into the wood, which is the reason for the fragility of the new coating.

It is very important when painting to use the right tool and use the right coloring composition, as well as strictly follow the technology of applying paint. It must be borne in mind that the antiseptic used must be combined with the coloring composition. With the wrong selection of dye and primer, it is impossible to obtain the desired effect, in addition, such a coating will not last long.

Long-term ideal preservation of the outer side will provide a wooden house made of timber by painting. Simply smearing paint on the logs' sides is not enough to create a reliable coating to protect a log home from constant exposure to moisture and wind, dust and debris, harmful insects and mildew. Painting a wooden house from the outside is a responsible action! The main thing is to choose the right paint for painting the house.

• Until now, oil paints based on drying oil are actively used.

Drying oil deeply impregnates the wood layer, providing its reliable protection. In addition to everything - the availability of acquisition, a wide choice of colors, low price. Of the minuses - long drying, fast fading and dependence on precipitation (rain or wind significantly reduce the quality of the coating with oil paints).

• A wide choice among acrylate paints.

These paints are chosen by 80% of consumers when painting a house from a bar outside, especially if they live in the northern regions. This is the quality standard for exterior finishes at low temperatures.

The absence of a pungent odor, a “breathable” structure (does not clog pores, while preventing the penetration of moisture), frost resistance are the main qualities of acrylates. Of the additional advantages - a wide range of colors, the ability to mix different colors without tarnishing and fading. Fast drying. Service life - up to 6-8 years. Updating the previous layer takes place without stripping the previous one.

Among the shortcomings - when stored in sub-zero temperatures, the paint after defrosting is absolutely not suitable, both for painting the outer walls of a wooden house, and for use in general.

• Alkyd-acrylate paints (Al/Ak).

Appeared on the market of paints and varnishes not so long ago, but have already won their staunch admirers who prefer to improve the beauty of their log home. Al/Ak is a covering antiseptic, which allows not only to protect the surface of the wood, but also to “highlight” its texture, to reveal the features of the samples used for the timber. Service life - up to 10 years. This material is in no way inferior to the usual paints, but looks much more impressive when applied.

• Azure and varnish.

They have the property not only to emphasize the beauty of wooden surfaces. Painting a house from glued laminated timber with such materials will reliably protect against atmospheric influences. There is less wax in azure, but it saturates the wood more deeply, which is of course good.

• Oil-wax coatings. It is easy and pleasant to work with this material!

Firstly, there are more opportunities for freedom of applying material for painting a wooden house from the outside, such compositions can be used inside without any risk of “burning out” from a pungent odor. Secondly, oil-wax is not inferior to ordinary varnish in wear resistance, surpasses alkyd-acrylic compositions in terms of economy and is no less environmentally friendly than acrylate paint.

Thirdly, the material allows you to paint the house outside in two or three different colors, layers are applied on top of each other, while the first layer will “look through” the subsequent ones. Fourthly, after painting through all the layers, the pattern of the tree from which the house is composed will be visible.

Of the obvious advantages - it is possible to apply (paint) the house outside on a tree of natural moisture, regardless of whether the house is made of glued laminated timber or logs.

The composition of the oil-wax involves the impregnation of wood fiber to give it special elasticity, resistance to cracking, an obstacle to moisture gain from the outside, but at the same time allows it to dry naturally, letting moisture out of the log or beam. Thus, wooden houses dry almost without cracks, which, of course, only improves their appearance.

There were no obvious disadvantages when painting glued laminated timber or processing a wooden house from a solid log with such a composition. Unless - the price "bites".

We minimize costs

The facades of wooden houses made of gun carriage, rounded logs or profiled glued beams need protection. The sooner the house is painted from a bar outside, the less hassle with maintaining a beautiful facade. The choice of material for glued beams depends not only on its quality, but also on its price.

What paint to paint a wooden house outside? More expensive or cheaper? On the one hand - cheaper, "economy class", so to speak.

Cheap facade paint, as a rule, does not exceed 100-200 rubles / kg. However, it will soon begin to lag behind the painted surface, crack and begin to peel off. And this means that in the near future it will be necessary to regrind the facade and subsequent repainting. Is this use economical?

Facade paint for painting the outside of a "middle class" house is more expensive: 150-300 rubles / kg. The manufacturer recommends it as a durable reliable coating for 4-5 years. This, of course, is better than the "economy class" (2-3 years), but here again atmospheric phenomena begin to play their role. The more rains, winds and frosts, the less hope for maintaining the durability of the "middle class" coating. And again - rip off, putty, grind, paint ... Calculate the area of ​​\u200b\u200bthe facade and multiply it by the cost of 1 kg. selected paint. Are you ready for such expenses every 3-5 years?

Premium coverage. These paints are not cheap - more than 300-500 rubles / kg. However, they will provide protection for the facade of a wooden house for at least 10 years, subject to the technologies for painting a wooden house specified by the manufacturer. For 10 years, it is quite possible to save up not only for a new coating for the house, but also for a paving extension to it.

It turns out that the cost of expensive paint will be more justified than buying cheap coatings - the miser pays twice!

Calculation of the required amount of paint

When you have decided which paint is better to paint a wooden house on the outside, before placing an order in a store, you need to correctly calculate how much this paint will be needed.

The volume of consumable material per 1 sq.m is indicated on the packaging. Be careful! This volume is indicated for the consumption of paint when applied in one layer.

Painting of log houses on the facade is carried out in two layers! You will need the amount of paint multiplied by 2 + a small reserve for unforeseen needs, so that you definitely have enough.

Where to start painting?

Looking forward to good weather! It makes no sense to start such important work when “the sea is rocking and a hurricane is raging”, and the temperature also matters. Permissible temperature "swings" should also be indicated by the manufacturer on the packaging of the coloring material for a log house or a house made of glued laminated timber. Good weather is a guarantee of high-quality work on painting the facade!

• Wall sanding.

The walls of a log house must be “smoothed” very carefully, so you should pay attention to the processing of a log even at the stage of buying a log house. For walls built from glued beams, it will be enough to sand once with a grit of 150-180, this will already create an optimal quality for applying a primer.

After cleaning, the treated surfaces should be wiped with a damp cloth.

• Primer.

Creating a solid, dense, carefully primed surface is a must before painting your home with your chosen paint. The primed walls are:

• Strengthening the surface before applying paint so that there is no dust.
• Less moisture absorption by the wooden base of the paint, which allows you to use the coating more economically.

Walls made of glued laminated timber do not require the application of an antiseptic - it is added to the glue itself. It is necessary to prime the surface in the same way as the paint, then the paint itself will lie in a more even layer. Before painting directly, the primer must dry well!

How can one not remember about oil-wax coatings, which can be applied not only to “unseasoned” log cabins, avoiding the formation of cracks and “blue”, but also painting the timber with them is many times faster.

• Painting

If the timber facade is not hidden under other finishing materials, the paint must be matched to the overall design of the site. The facade can be darkened with a coating or, conversely, brightened, or you can give it any colorful shade. It all depends on how to paint the houses from the timber outside. The "application tools" will also depend on this choice. The paint on the facade is applied with a brush, roller or spray gun, depending on the density of the selected paint, its viscosity and the texture of the base.

Painting an old house

It’s great when the owner chose to improve the beauty of his house without covering it with a “thick, thick layer of chocolate” of oil paints. But what if you are the owner of an old, old wooden house that has been repainted in different colors more than once? Under multiple layers of rough paint, its walls have darkened, mold has spread in some places, and voracious insects have undermined the once strong wooden crowns.

What should we do? Paint the house! After the necessary repair work, we arm ourselves with sandblasting and cleanly peel off everything until a clean tree appears.

Then everything is the same as for a brand new cobbled house: we grind, primer, select the desired paint for a wooden house and paint the outside of our hearth in a new, life-affirming color, giving it harmony, attractiveness and an initial look to the envy of all neighbors!

Painting wooden facades (1 video)

Despite the modern abundance of various building materials, wooden houses remain traditional for almost all regions of Russia. From time immemorial, their log cabins were erected in both urban and rural areas. In our time, the possibilities of using wood have expanded significantly - today processed timber is widely used for the construction of residential buildings, frame structures made of lumber and plywood or chipboard () are used.

When purchasing one of the protective solutions offered for sale in a fairly wide range, you need to pay attention to the packaging label (label). It must necessarily indicate the scope of its application, that is, a specific composition is intended for internal or external work.

Protective compounds are transparent, preserving the completely open texture of wood or giving it a glossy brightness or soft matte finish. However, there are also tinting solutions that make the material one or more tones darker.

There are several types of different solutions that can be designed to protect against various negative effects on wood - these are conventional and biomoisture protective antiseptics, fire retardants, bleaching and primers. To understand how they differ, it is advisable to consider each of them. This will make it easier to make the right choice.

Wood preservative prices

antiseptic

• Antiseptic solutions are designed to combat fungus and mold that have appeared on wooden surfaces, as well as to prevent the emergence of new formations. These compositions, in turn, are also subdivided according to different criteria.

So, on sale you can find two types of antiseptics - these are impregnations and coatings:

— Impregnations are designed for deep penetration into the wood structure. When purchasing this version of the solution, it is necessary to carefully study its composition, since some of these processing agents are very toxic;

— Coating solutions create a film on the wood surface and protect it from moisture. They are especially relevant for covering walls in rooms with high humidity, for example, in a bathroom or in a bathhouse.

Antiseptic solutions are produced on different bases, and according to this criterion they are divided into the following:

- Water-soluble compounds are environmentally friendly, so they are great for treating indoor walls. They are usually used under water-based paints. A significant disadvantage of such antiseptics can be called the fact that over time their protective qualities decrease.

- antiseptics made on an organic basis have high protective properties. However, they are more suitable for the facades of wooden houses, as they contain toxic components, and are also unsafe in terms of flammability during application and before drying.

- Oil solutions of antiseptics are most often used for facade surfaces, wooden sheathing of a balcony or loggia, especially if the house is located in a region with a harsh climate.

- Combined solutions, consisting of oil and high-carbon components, are used to treat both external and internal wooden surfaces. Moreover, they are also suitable for rooms with high humidity, providing their surfaces with high-quality protection.

The last version of antiseptics is the most expensive, since, in fact, it becomes a universal remedy used in any construction and finishing areas.

• Biomoisture protective antiseptics are used as an effective measure of protection against fungal formations, mold and insects harmful to wood. This type of antiseptic creates a protective barrier on the surface of the wood, and also serves as a decorative coating. Therefore, a biomoisture protective solution can be called universal, since it performs two functions at once.

Thanks to these properties of the antiseptic, not only money will be saved, but also time for staining. It is these solutions that are in high demand among the owners of wooden houses.

• flame retardants are used to give wood a higher resistance to fire, that is, a material treated with such a composition is able to withstand exposure to open fire for a long time without igniting.

Flame retardants are divided into two groups according to their reaction to fire:

- One group of solutions contains salts, due to which, when wood is exposed to high temperatures, gases are released that can prevent rapid ignition.

- The second group of flame retardants blocks the flame by foaming, which occurs when wood is heated to elevated temperatures and creates a protective coating on it.

More effective flame retardants, according to experts, are those that include sodium salts, as well as orthophosphoric, pyrophosphoric and tripolyphosphoric acids.

• biopyrenes are called impregnations that combine the functions of both a fire retardant and an antiseptic. Similar solutions can be used to treat walls from the inside and front side.

Due to the fact that this tool is a complex consisting of all the components necessary for protecting wood, using it, you can save some money, time for work and waiting for the layers of several different solutions to dry. So the costs are likely to be justified.

Prices for biopyrene

biopyrene

• Primer on wood is another effective protective agent with which preparatory work is carried out before painting. These solutions are not only designed to prevent various manifestations and effects that are destructive to wood - they also create a good adhesion between the surface of the wooden wall and the applied decorative layer. Water primers for wood can be transparent, translucent and opaque. According to this criterion, they are selected depending on what effect is planned to be obtained as a result.

For example, if it is planned to paint the primed walls with a dense layer of paint, then it does not matter what kind of transparency to cover the wood with a primer. In this case, rather, it is only necessary to take into account that a smoother surface will give an opaque version of the soil. Transparent compounds work like an impregnation, penetrating into the structure of the material and filling its pores, but they do not have the property of creating a protective layer on the surface of the wood.

However, whatever primer is used, it creates a good base for bonding between wood and paint.

• Wood bleaching products are used to remove various manifestations from its surface that spoil the appearance of the entire wall - these can be blue, stripes or dark spots. Simultaneously with the removal of the above-mentioned flaws, these compounds also perform a protective function.

Bleaching solutions can be one- or two-component. The connection and mixing of the second version of the compositions is carried out immediately before applying them to the wood. The formulation of some of the products provides for them to be washed off after a certain period indicated on the package, while others remain on the wood for painting as an antiseptic. Therefore, before purchasing one or another type of bleach, you need to pay attention to the packaging, which contains instructions for using the solution.

Lacquer as a protective and decorative agent

As a protective agent for wooden walls, in addition to the above-mentioned agents, varnish solutions are used, which can also be made on a different basis. To know which of the existing varnishes are suitable for indoor use, you need to consider each of them in more detail:

• Acrylic lacquer consists of polyacrylates and is organic or water based. The solution is an environmentally friendly product without a strong odor, and therefore it is often used to cover the surfaces of not only wooden walls from the inside of the premises, but also furniture.

However, it must be taken into account that the layer formed by this type of varnish is not very resistant to abrasion. And this means that the coating will have to be updated quite often, and this is especially true for furniture accessories.

• Polyurethane varnish It is made on a water basis, but despite this, it has high strength characteristics, including abrasion resistance. The composition of this protective agent is environmentally friendly and almost completely odorless after drying, so it is perfect for applying to wooden walls inside the house.

Some experienced craftsmen recommend adding hardening agents to the polyurethane solution to extend the life of the finish. Due to its high strength characteristics, this varnish is often used to cover plank wooden floors and parquet, so it is fully suitable for walls. However, the price of these products is quite high, and this factor is the main disadvantage of such material.

• Alcohol varnishes and varnishes able to create a durable glossy layer on the surface of the wood. However, despite the high strength, compositions based on this are not resistant to moisture, therefore they cannot be used to cover walls in bath rooms, in a loggia and on a balcony, since the coating layer will begin to peel off.

Lacquers are made on the basis of natural resins, so the price for them is quite high. This circumstance, coupled with low moisture resistance, predetermine the fact that such compositions are not in high demand.

• Nitrocellulose varnishes consist of organic solvents and cellulose nitrate with the addition of synthetic resins to the solution.

This type of varnish is divided into two varieties:

- One of them is for preparatory work, that is, it creates the basis for the outer layers.

- The second - itself is a decorative coating.

They differ in the digital marking applied to the packaging. Typically, preparatory solutions have the ability to dry quickly - this quality is provided by the manufacturer to eliminate delays in the work. Therefore, when purchasing this composition, you need to pay attention to the instructions printed on the packaging with varnish.

Nitrocellulose solutions create a fairly strong top layer on the surface of wooden walls, which is transparent, so it does not change the natural color of the wood. Therefore, if you intend to preserve the beautiful textured pattern of the internal surfaces of wooden walls, then this type of varnish is well suited for this purpose. True, it is necessary to work with such compounds with extreme caution - they are extremely flammable in an uncured form (before the nitro solvent volatilizes), and will emit a pungent odor before drying.

• Oil varnishes are made on the basis of artificial or natural resins, in addition, they also contain modified natural oils, desiccants and solvents. Varnishes of this type penetrate well into the wood and form a strong protective layer on its surface, giving the wood a warm ocher shade.

Solutions are well suited for interior finishing work, they cover wooden walls, floors, as well as pieces of furniture.

• Alkyd varnish It is made on the basis of glyphthalic or pentaphthalic resins, to which desiccants are added. Since this type of varnish contains oils used as solvents, they are also often called oil varnishes. However, the alkyd version of the varnish differs from the oil varnish in its higher physical, technical and operational characteristics, therefore it is successfully used not only for interior, but also for exterior decoration.

In addition to alkyd varnishes, alkyd-urea solutions are on sale, consisting of alkyd and aminoformaldehyde resins. This type of varnish can be called a two-component varnish, since its drying is possible only when acid hardeners are added to the mixture. Such a varnish is kneaded immediately before applying it to the surface of the wood, since after preparation the solution remains suitable for a very limited time, and after it has hardened, it will no longer be possible to dilute it.

This type of varnish is well applied and, after hardening, forms a strong protective layer on the surface, which has high wear resistance. Due to this property of alkyd-urea varnish, it can be used not only for wall covering, indoors, but also

Wood wall paints

In order to paint a wooden house inside, paints made on any basis are suitable. Nowadays, various types of this material are presented in specialized stores in a very wide range. And one of the most important criteria when choosing a composition should be its safety, that is, the paint should not emit harmful toxic substances both during its application and during the operation of the premises.

Therefore, when buying any paintwork material, you need to pay attention to its characteristics, which should be presented on the package. In addition, it is recommended to obtain information from the sales assistant.

So, in specialized stores today you can find the following paints for finishing wooden surfaces:

• quite popular, since with the help of them the wood can be covered with a dense layer of paint, or you can make it translucent, thereby preserving the textured wood pattern. If the latter option is chosen, then the paint must be diluted with water to the required consistency.

Aqueous emulsion solutions are distinguished by the absence of a sharp unpleasant odor and the fact that they do not emit toxic fumes harmful to humans. Therefore, they can be safely called environmentally friendly material. The layers applied to the prepared surface adhere well and dry quickly, but are inferior to varnishes in their strength and wear resistance.

silicone paint prices

silicone paint

• silicone paints are a solution of silicone resins, and thanks to them, they create a reliable and durable coating on the wood surface. The colorful composition has excellent technical characteristics, it is inert to mechanical stress and has good vapor permeability, that is, it allows wooden walls to "breathe".

Moisture-resistant silicone film is resistant to abrasion and UV radiation. The applied coating is distinguished by enviable durability and is not only a protection for wood, but also a way to hide some flaws on its surface. The coating does not crack when the walls shrink, as it has good ductility.

• silicate colorful compounds are made from "liquid glass", therefore they have a large number of positive characteristics. They are highly resistant to ultraviolet rays, to high humidity, low and high temperatures, as well as to open fire.

Silicate paint is an environmentally friendly product, since it does not contain substances harmful to humans and does not emit toxic fumes. Therefore, this type of material is excellent for covering internal surfaces, not only wooden, but also made of other materials. Given all the characteristics of this finishing material, we can conclude that it is well suited for a room where conditions that increase humidity can occur, for example, an unheated balcony or veranda.

True, silicate compositions are completely incompatible with finishing solutions made on a different basis. That is, in the case of repainting, it is necessary either to reuse silicate paint, or to clean the surface to the very base.

• are made on a water basis, but have characteristics that exceed those of oil compositions, therefore they are able to give wood reliable protection and preserve its natural color. Due to its elasticity, paints have excellent adhesion to surfaces, they do not deform or crack.

The paint can be used for painting both internal and external surfaces of the building.

• Alkyd enamel used for painting both facades and internal surfaces of walls. It creates a protective glossy or matte layer on the wood, making it smooth and aesthetic.

However, this composition also has its minus - over time, the alkyd white enamel turns yellow, and the paint that has the color burns out, therefore, to paint walls, for example, a balcony located on the sunny side, or which constantly receive a "portion" of sunlight, apply its not recommended.

• Oil paints have a considerable number of advantages compared to other compositions and are applicable for both internal and external coating of wooden surfaces. High-quality solutions are highly resistant to external mechanical stress and high humidity.

The obvious disadvantages of oil paint compositions include a long drying period, low UV resistance (over time, the coating begins to crack and peel off) and airtightness. This type of paint is most often used to cover facade surfaces, but even then - with a fairly frequent update of the finish.

• Wax natural paints or liquid wax are made on a linen basis and have been used to cover wood for more than a decade, so they can be called a traditional material. Wax is well absorbed into the wood structure, making it waterproof.

The solution can be transparent or tinted. If you plan to keep the original color of the wood, then a transparent wax option is chosen, and if the wooden walls need to be darkened, then you should use a tinted solution. Wax paint is easily applied to the surface, but acquires the selected shade only after complete drying. Therefore, it is recommended to first apply a similar composition to a small area of ​​\u200b\u200bthe wall and wait for it to dry to make sure that the optimal paint tone is chosen.

Useful tips for purchasing paint and staining

When choosing and purchasing paint for wooden walls, it is very important to pay attention to the date of manufacture of the composition and the availability of certificates confirming its quality and sanitary compliance. If the seller cannot provide documents for the goods, and the date of manufacture is not stamped on the package, but is written on paper and pasted on top, so to speak, interrupted, then it is recommended to immediately refuse to purchase such paint, especially if it is purchased quite expensive option.

The fact is that if the paint is expired or frozen, then it may simply not lie on the surface, even if it is well prepared, and you can determine the quality of the composition only by opening the package and trying to apply it to the wood. For example, it will not work to color anything with a frozen solution, since the paint will most likely curl up and will have the consistency of liquid cottage cheese.

If the paint is of high quality, it will be easy to apply to the surface, which means that a person who has never even done such repair work can handle painting the walls.

• The first thing to note. It is a common phenomenon when many homeowners, when making repairs in the house or on their own, carelessly treat the preparatory stage of work, as they consider it optional. However, if the base for the decorative coating is uneven and untreated with protective agents, the desired result should not be expected. In addition, after a short time, even flaws that are imperceptible immediately upon completion of work will begin to appear, for example, such as blue, blackness of wood or “tar pockets” near knots. Therefore, the preparatory process must be considered mandatory and carried out with the highest quality.
• When processing wood with one of the protective compounds, it is necessary to carefully process the end parts of the logs or timber if they go towards the rooms. If the walls of the house are lined with clapboard, then its side surfaces should also be carefully treated with antiseptic solutions.
• All protective and coloring compositions are applied to wooden surfaces in thin layers along the fibers, otherwise their absorption into the wood will be uneven, which will negatively affect the overall appearance.

• So that an excess of paint is not created on the brush, and it does not flow, but lies flat, it is recommended to use a simple device consisting of two clerical or ordinary rubber bands. One of the rubber bands is put on the bottom and top of the can, and the second along its diameter. The second elastic band will hold the first one, preventing it from slipping to the side.

Having dipped the brush in the paint, it is pressed against a stretched elastic band, leaving the excess solution in the container.

• When applying paint to the surface of wood, you should not try to cover it immediately with a thick layer, as the coloring will turn out to be sloppy. If you plan to get an opaque surface, then it is worth applying the paint in several thin layers, each of which should be applied after the previous one has completely dried.
• When painting clapboard walls, the last top coat is best applied starting at the top and gradually working your way down to help smooth the surface of the wall.
• The paint can look different in the jar and on the wall, so it is recommended to make a test painting, that is, apply the solution to a small area of ​​the wall in an inconspicuous area. It is best to choose the bottom corner of the surface.
• In order for the decorative layer to lie flat on the surface, experts recommend adding color to the primer one or two tones darker or lighter than the main color.
• The optimum temperature for painting surfaces is 22 ÷ 25 degrees. You should not carry out this process in hot weather, as the paint will dry too quickly and therefore unevenly. At too low a temperature, the fluidity and hiding power of the compositions deteriorate, and the duration of the drying period increases.

Step by step instructions for painting a wooden wall indoors

Having adopted all the above listed small tricks, it will be easier to cope with the preliminary stage and painting the walls. Having prepared all the tools and workplace necessary for the process, you can proceed to the finishing itself.

The main part of the work is occupied by coloring, which is why they require a more detailed description.

Illustration	Brief description of the operation to be performed
	For preparation and staining, it is necessary to have at your disposal some of the tools shown in the illustration. In addition to them, you will need a grinder with replaceable abrasive paper sheets and, possibly, a grinder with an iron brush. If the wooden wall has an old coating, you can use a building hair dryer and a scraper (trowel) to remove it.
	The first step is to clean the surface of the old paint coating (if any). To do this, the paint layer is heated to a state of softening and peeling off the wood, and then removed with a scraper or spatula. This work is quite lengthy and laborious, but it must be done with high quality, otherwise the remnants of the paint will show through the new decorative layer with unaesthetic bumps.
	If the wall does not have an old coating in the form of a paint layer, and during its operation has acquired an unrespectable appearance, or if wallpaper was previously pasted on it, its surface must be thoroughly cleaned by removing the top thin layer of wood.
	Restoration of such a surface is carried out with the help of a grinder, on which a brush with a soft metal bristle is installed, and then a grinder with coarse-grained (P80÷P120) and then fine-grained (P150÷P180) sandpaper fixed to it. In addition, cleaning the wall or its individual sections protruding above the common surface can be carried out using an electric planer.
	When the wood is cleaned, its surface must be sanded with a fine-bristled brush or sandpaper. In the event that a wall of new wood is being prepared for painting, it also needs to be sanded to smoothness. A lot of difficulties can be caused by cleaning and grinding difficult places, for example, between two logs of a log house. But here, as they say, nothing can be done - you have to "sweat" if you want to get a quality result.
	If there is no grinder, then you will have to grind the walls manually - this is a very complicated and long process, so it is still better to purchase a profile tool, since it will come in handy more than once in a wooden house. The polished surface must be cleaned with a vacuum cleaner from the dust formed during the grinding process.
	The dust-free wooden surface is then covered with one of the selected protective agents - it can be an antiseptic and flame retardant, or one of the compositions described above. Such an operation can be performed using a roller, a wide brush or a spray gun, depending on the relief of the wall and its area. If it is log, then the work will go faster if you carry out this process with a sprayer. At the same time, we must not forget about the need for increased precautions - many primer protective compounds are very toxic before absorption and drying.
	As a preparatory, and sometimes even the main decorative layer, one of the types of varnish is used, which is applied with a wide soft brush.
	If, after the primer dries, it is planned to apply paint or dark tinting varnish to the surface, then the ceiling should be protected from getting the solution on it. To do this, it is recommended to stick masking tape on the upper edge of the wooden wall to the ceiling, which can be easily removed upon completion of work and does not damage the plastered or painted ceiling surface.
	To paint wooden walls, you will definitely need a soft brush and roller. The roller will significantly speed up the work, as it immediately covers a large area of ​​\u200b\u200bthe wall and evenly distributes the paint solution over it. True, this is possible only on flat surfaces - when painting a log wall, a roller will not become a great helper.
	A brush is needed for painting hard-to-reach places, for example, corner areas or horizontal joints between logs. Painting is recommended to be carried out in two to three approaches, but each of the layers must cover the entire area of ​​\u200b\u200bthe wall, otherwise the paint will lie unevenly. Each subsequent layer is applied only after the previous one has completely dried.

So, the process of painting wooden surfaces in the house is a very laborious, large-scale task, which, however, any owner must cope with. And for successful work, in addition to your own desire, you must:

• Have the necessary tools of good quality.
• Select and purchase high-quality primers and paints and varnishes for the preparation and painting of surfaces.
• Carefully, without simplification, carry out all the preparatory processes, without convincing yourself that "it will do."
• To paint slowly and without trying to complete it in one approach, that is, do not apply paint in one thick layer - this approach will result in nothing but streaks, overspending of paint and a sloppy surface.

If you strictly adhere to all these conditions, the coloring will definitely turn out as it was originally intended, that is, neat and uniform, and the finish will last as long as possible.

And at the end of the publication, we suggest watching a meaningful video in which the master tells and shows how to properly paint the walls of a house from the inside from a natural wooden beam.

Ecological cleanliness in the construction of private cottages is gaining more and more popularity. For this reason, wooden facades are no longer uncommon. Everyone is well aware that wood is beautiful in texture and at the same time a very capricious material in operation. In the article we will tell you how to maintain the strength of natural wood, protect it from the harmful effects of the external environment. Let's figure out why impregnations are required and what paint is better to paint a wooden house. Let us describe the technology for carrying out measures for the processing of a wooden facade, taking into account the previous operation.

It does not matter whether the house is lined with a building board according to the curtain wall system or completely assembled from timber, the wood used in street decoration needs protection. There are objective reasons for this, any wooden material has the following unattractive properties:

• easy flammability and excellent combustibility;
• porosity and, as a result, moisture saturation;
• deformation under the influence of various temperatures;
• exposure to fungus and mold, as well as bugs - pests.

Unprotected wood dries out over time, loses its attractive texture and color (grey), becomes loose, and therefore not durable. That is why the tree on the facade should be protected from the following factors:

• the action of UV rays;
• high humidity;
• pest insects.

In order to enhance the natural excellent characteristics of wood, and at the same time reduce the risk factors for unpleasant situations, the wood is impregnated with special compounds and treated with paintwork materials (paints and varnishes).

Impregnation

Priming solutions or impregnations can be used as a preparation material for painting, and can also be used as a finish. There are 3 types of primers:

• antibacterial (against fungus and mold);
• flame retardants (from the action of fire);
• water repellent.

Since it is difficult to give preference to only one method of protection, fire protection compositions have been developed that include 2 mechanisms. Water-repellent primers generally protect against UV rays and strengthen the wood.

On a note! All primers have a short life as a top coat. Therefore, without further staining, the facade will have to be processed regularly every 2-3 years.

Impregnation treatment will not only improve the appearance, but also increase the life of the wood. For facade work, deep penetration compositions on an organic basis should be chosen. Such solutions, as a rule, are toxic, have a characteristic unpleasant odor. When working with them, PPE (personal protective equipment) is used: gloves, goggles, a respirator.

On a note! Most primers have a clear base, which means that treatment with such a composition will preserve the natural texture and color of the wood.

Facade paints

Any coatings used for facade work must have a certain set of qualities. But in the situation with wood, this list increases, in view of the natural vulnerability of the tree.

Characteristics that any facade material should have:

• resistance to atmospheric precipitation of various temperatures;
• resistance to temperature changes;
• coating color stability;
• abrasion resistance;
• strength to mechanical and physical influences;
• chemical inertness.

When it comes to painting a wooden facade, paint requirements are supplemented by the following criteria:

1. Plastic. Wood is a breathable moving material. Logs and boards can change volume depending on temperature and with changes in humidity levels. Therefore, the decorative coating material must also be elastic and not crack.
2. Vapor permeability. Decorative material should not create a barrier for moisture to escape from the body of the wall in order to prevent the onset of decay.
3. Fire safety. The material itself must not only protect the wood from burning, but also be non-flammable.

On a note! When choosing a paint for working on a wooden facade, you should pay attention to the antistatic properties of the material. A paint coating with a high given indicator will accumulate less dust and fine dirt, which means that the facade will be much easier to maintain.

Classification of coatings for facades

In fact, when choosing a paint, the type of future surface is selected, which will be obtained after applying the material to the wood. For outdoor use, all paints are classified according to the type of solvent, the texture obtained and the quality of the gloss.

Gloss

The dullness or gloss of the surface is not only beauty. Glossy coatings are more durable, because they contain more resins. Matte surfaces are usually obtained from breathable decorative compositions. In addition, the glossy finish is more resistant to moisture and less prone to abrasion.

Manufacturers indicate on the bank the degree of gloss of the final coating with a number in the range from 0 to 100. It is customary to divide the degree of gloss into 6 main groups.

Table 1. Degrees of gloss.

Solvent

All types of paints are diluted with 3 types of solvent:

• water, the compositions are called water dispersion;
• organic chemistry, such as white spirit, acetone, solvent;
• inorganic compounds.

White Spirit

Paints diluted with inorganic compounds are rarely used in everyday life. For wooden facades, materials are usually used that are diluted to the desired consistency with water, as well as enamels, varnishes, alkyd and oil paints. The specificity of organic solvents is an unpleasant odor.

On a note! Water-dispersion materials can only be applied at positive temperatures. Paints diluted with organic compounds can also be used with a slight minus.

Texture

Facade paints are textured (volumetric) and forming material for smooth surfaces. Textured compositions are not used for wood processing, since wood initially has a rich texture and does not need additional decoration. Smooth compositions can be transparent, such as varnishes, or dense, like enamel.

Types of paints

Before you start painting a tree, you should decide on the quality of the facade you plan to get in the end. Modern paints and varnishes allow you to process wood and at the same time get surfaces that are different in appearance:

• natural in color and texture, with varying degrees of gloss;
• matte with a touch of color, but with the preservation of texture;
• opaque and glossy.

Consider the most popular compositions, their positive qualities and some disadvantages.

Oily

The most famous compositions and the most affordable. The material completely covers the natural color, creating a dense film on the surface. It is this layer that perfectly protects the wood from moisture, the coating has almost zero absorbency of any solutions. Oil paints based on drying oil are produced.

Such paint has a very short service life, quickly fades and begins to crack under the influence of temperature. The reverse side of hydrophobicity is the lack of vapor permeability, that is, the layer does not allow moisture to pass through, but also does not allow the tree to breathe, which can lead to rot inside the wood mass.

Among other things, such compositions dry for a very long time, about 10-12 hours. More suitable for the maintenance of low buildings, fences or sheds, as they require regular updating.

Alkyd

Compositions formed on the basis of resins with the addition of oils. The PF marking is more understandable to a wide circle. The composition does not penetrate to a sufficient depth, forming a strong film on the surface. They dry faster than oil formulations, but have a very unpleasant odor. They form a hydrophobic durable layer that is not subject to fading from moisture and temperatures. It is this combination of qualities that makes alkyd paint very popular for processing wooden facades in regions with high humidity.

The paint loses color when exposed to direct sunlight, and over time the surface loses its gloss. If it happens that the paint was applied to damp wood, then the layer will begin to bubble.

Silicone

Compositions based on organic compounds or resins. Worked well in humid climates. The coating with silicone (or latex) paint is durable even after applying one layer. The surface has a high degree of chemical inertness, the facade can be washed with almost any means. The paint does not fade in the sun and does not fade. In addition, the coating is resistant to mechanical stress and abrasion. The main drawback is the very high price.

We will talk in detail about the advantages of silicone paint for the facade, and also consider the painting technology.

Acrylic

Popular paints for finishing wooden facades. On sale there are acrylic paints on a water-dispersion basis, that is, they are diluted with water and compositions on an organic solvent. They have excellent adhesion, form a vapor-permeable layer that is resistant to moisture and ultraviolet. That is, the coating does not fade, the color is not washed out by rain, and the wood breathes. The paint has no unpleasant odor and dries quickly. The protective layer is resistant to abrasion and has a long service life.

On a note! Commercially available acrylic compounds that allow you to carry out repairs even at low temperatures.

Water dispersions

Such paints can be silicone, silicate and acrylic, they are united by the fact that they are all diluted to the desired consistency with clean water. Depending on the main substance, the price of the product can vary greatly. The advantages of such compositions include:

• absolute ecological cleanliness,
• vapor permeability of the layer,
• rich color palette,
• inertness to chemicals,
• long service life.

The paint dries very quickly and is very easy to apply.

Some shortcomings are still present. The water in the dye will penetrate the wood, so some surface movement is expected. Before applying paint, the facade should be treated with a water-repellent primer.

How to paint a wooden facade yourself

If there is a need to paint the facade in an already operated house, it is quite possible to do this work yourself. To do this, you need to take care of the availability of free time, it will take a lot. Purchase consumables in advance: a primer and paint in the right amount, a coloring pigment (color) and a solvent if necessary. Approximate consumption rates of the compositions and the service life of the coating in the table below.

Table 2. Consumption rates of compositions and service life of the coating

In order to put the facade in order, in addition to materials, the following tools will be required:

• ladder or scaffolding,
• brushes of various widths
• rags,
• angle grinder (grinder) with discs for grinding,
• putty knife,
• construction mixer with a nozzle for mixing paint.

Depending on the type of paint used, various personal protective equipment will be needed: gloves, a respirator, goggles.

Technology

The whole process takes place in 4 stages. At the same time, scrupulousness and attention are required to complete the work. It is important to do everything carefully, without leaving untreated places.

Stage 1. Removal of the old coating. This procedure is performed if there is an old paintwork coating. It needs to be removed. To do this, you can use spatulas, a metal brush, sandpaper or a grinder with a nozzle. There will be quite a lot of dust, so you should work with glasses and a respirator.

All work is carried out in dry, not hot weather. You will have to protect the entire area of ​​\u200b\u200bthe facade, including the joints of logs or boards. In order for the work to be done efficiently and without delay, dismantle the elements of the drain, shutters and trim from the facade in advance. In addition to the old paint, dust and street dirt should be removed from the facade.

Important! Do not leave the old paint, even if the layer is firmly seated on the surface. Its service life will expire, and it will peel off along with the new coating.

Stage 2. After the facade is cleaned of paint, the wood is sanded and puttied. If there are places of darkening, or foci of fungal infection are visible, the top layer of the material should be removed to a clean texture. The rest of the surface is leveled. Existing defects on the surface are eliminated by puttying. Before proceeding to the next activities, the putty must dry out. The putty material must be combined in composition with impregnation and paint.

Stage 3. A deep penetration impregnation is applied to the cleaned wooden surface, the composition of which is selected depending on the characteristics requiring reinforcement. Usually, impregnation is applied with a wide brush, along the fibers, in order to preserve and emphasize the natural texture of wood.

Do not neglect priming, impregnation will not only improve the quality of the wood, but will increase the adhesion of the paint to the surface, while reducing the amount of material consumed. Even despite the fact that wood primers have a rather high price, their use justifies itself. Before applying the paint, the impregnation must dry, the period of complete drying is indicated by the manufacturer on the packaging.

Stage 4. Before starting work, ask about the long-term weather forecast. Rain is not suitable for coloring, just like heat. In addition, work should be carried out in the daytime, when the dew has either already evaporated or has not yet settled, that is, from 10 am to 6 pm. The paint is applied in several layers along the fibers. Each next layer should be applied only after the previous one has dried.

Some nuances of coloring

It would seem that the process is quite simple and transparent. But here, as elsewhere, there are nuances:

1. If the facade has external metal fasteners, then before priming and painting, they should be puttied with an oil or acrylic composition to match the color of the tree. Such work will be especially relevant if the finish coating is planned to be made transparent.
2. If you carefully approach the issue, then you can use several impregnating compounds, water-repellent impregnation is applied last.
3. For better surface quality, after the impregnation dries, the wood should be sanded from small roughness and pile.

Conclusion

The choice of material for processing a wooden facade mainly depends on the wishes of the owners of the house. But when choosing paint, you should also take into account the climatic conditions of operation. For humid areas or areas with hot climates, different formulations should be used. At the same time, be sure to strictly follow the instructions for applying the paint, as well as properly prepare the surface before starting work.
