A wooden house needs exterior decoration. This statement will be approved by every professional builder and owner of a wooden house. In addition to the decorative functions, the decoration also performs protective - a house made of wood is subject to various dangers - the effects of moisture, sunlight, biological pests.
To protect and decorate buildings from logs and beams, a variety of materials have been created that are used almost equally widely and have found supporters, both among the owners and among the builders of wooden houses. In this article we will talk about paints, how to paint a wooden house outside and why paint is in many cases preferable to other materials.
Features of facade paint on wood
The process of painting houses built of wooden material differs only in that they need to use special tools for processing. The most important points that distinguish the usual technological process of painting the facade are mainly in the preparatory work.
If the building is new, then before proceeding with the priming of the surface, its treated with special solutions with anti-tar and antiseptic action. Such an event is necessary to prevent the release of resins from natural wood, as well as to provide additional protection for the array from damage by insects and other pests.
As for the primer itself, the material selected is also specially designed for wooden surfaces. Otherwise, the whole process of painting a wooden house is quite simple. In addition, the painting process of a wooden house involves additional work to ensure the protective properties of the wall surface. Although there are also such paints, using which, there is no need to resort to any additional measures, except to complete the entire process.
Advantages and disadvantages
Regarding the benefits that can be obtained from the use paints and varnishes for finishing the facade of a wooden house, you can identify the following:
- paramount - this is creating an attractive appearance of the building (including the old cover) and the ability to realize the most diverse and original ideas for decorating your home. The choice of such materials in the construction market is very large, and allows you to purchase the desired type of paint,
- materials have a high level of hiding power, when applied, create a dense and elastic layer,
- the color rendering of paints and varnishes is very good, differs in saturation and a clear texture,
- after applying paints and varnishes intended for the treatment of wooden surfaces, the facade of the house does not lose its breathable properties,
- the dried paint layer protects the structure not only from unforeseen mechanical damage, but also prevents the formation of cracks in the tree,
- protective coating is able to prevent the accumulation of dirt particles, which greatly facilitates the process of caring for the building.
For such materials, there are some disadvantages that abut the component composition of some paints. Most materials have a high level of toxicity, therefore they are allowed to be used only in open areas.. The price category of materials is quite high.
In addition, some varieties of paints are not able to maintain their original color for a long time, they darken or fade. However, the manufacturers of such materials have envisioned this and a high-quality paint coating involves re-coating the building with paint.
Materials intended for outdoor woodwork have certain properties that ensure a high level of quality:
- Materials helps remove excess moisturethen provide a protective barrier that prevents moisture from entering the structure of the tree.
- Paints protect the wooden surface from aging.
- The layer of material forms a specially film, which does not allow ultraviolet rays to destroy the structure of the tree, and also gives the tree strength, which prevents cracks from appearing for as long as possible.
- After processing with paints, wooden texture becomes more pronounced and attractive. This is due to the fact that the material penetrates into the smallest textured recesses in the tree and makes them more noticeable.
- Gives the facade of the building an attractive and aesthetic appearance.
Types of materials
The variety of colors on the facade is quite large, but you should pay attention only to the most popular and popular options. Allocate:
- A transparent variety of paints on wood contains only those pigments that are able to show the texture of the tree. Transparent paints are characterized by a high level of vapor permeability, which enhances the ability of the wood material to dry. The composition contains a substance that protects the tree from the damaging effects of UV rays. Using this type of paint on wood involves processing the facade 1-3 times a year, while removing the previous layer is not necessary.
- Paints containing organic solvents. These include:acrylic, alkyd and polyurethane varieties. They are characterized by a high level of water-repellent ability, they are resistant to sunlight, which allows the materials to maintain their color as long as possible. If necessary, repeat the processing, you must delete the previous layer. Such paints and varnishes are characterized by high toxicity and the disadvantages include the ability to undergo fire.
- Water dispersion formis one of the most modern varnishes for the wooden facade. For the solvent in this type of paint, an aqueous base is used, which, after the material is applied, evaporates. Due to this, the wooden facade acquires a high level of frost resistance. They are characterized by high vapor permeability and the ability to maintain light and color qualities for a long time.
- Oil paints in its composition contain drying oils, they are characterized by a very unpleasant odor, and they do not have high resistance to low temperature and high humidity. The drying process of the oil varieties of paints is very long. They are characterized by rapid wear, however, they hold tight. A distinctive feature of such a material is the ability to carry out work at a lower temperature regime than the water-emulsion varieties can do.
The construction market presents a wide range of paints and varnishes for the wooden facade by various manufacturers.
Of the most popular, the following are distinguished:
- Production of the USA, Sherwin-williams firm. This manufacturer uses the latest technologies, analogues of which do not exist yet. Such paints and varnishes are characterized by self-priming and are able to create a high-quality coating in just one layer.
- Duration exterior acrylic LaTeX. The materials are equipped with a lifetime warranty and have an increased ability to wear resistance. To cover the facade, it is enough to carry out a single-layer painting.
- Super exterior acrylic LaTeX. The warranty on paint is 25 years, while it is characterized by a distinctive feature that allows painting the wooden facade at low temperature conditions.
- Russian production,Paint Profi Tex. One of the most popular brands of coatings, which is characterized by an antibacterial effect and low cost.
- Finnish paintTikkurila, which can be used to finish the facade in low temperature conditions. It has a high level of protective properties against various adverse effects, the service life reaches 20 years. Gives the facade increased strength and protects against mechanical damage.
How to paint a wooden facade
How is paint best for a wooden house? As for the choice of the best paint and varnish material for the house, only the owner himself can answer this question, who knows all the nuances of the structure and the climatic conditions of the area. The most important thing is that the paintwork material meets all the necessary requirements and is able to protect the facade.
An important feature of paints for a wooden facade is the provided ability to repaint the entire facade. Having learned all the necessary list of requirements for paintwork, difficulties in acquiring a specific variety of material will not arise. It is recommended to purchase material for the decoration of the facade with a small margin, since in the future it will become necessary to tint some parts of the surface of wooden walls.
Having decided on the type of paint, and setting the day on which the decoration will be carried out, it is necessary to go through the preparatory phase before painting directly. It consists in cleaning the surface of the walls from the old paintwork, if any. To do this, use special solutions or a hairdryer.
If there are none, then the process can be carried out in the usual way, using a spatula or a wide chisel. As for the new structure, it is necessary to carry out the treatment with a solution with anti-resin effect.
To prepare the surface of the old building, the use of putty will be required, with the help of which the formed cracks and chips are overwritten. After waiting for the complete drying of the material, the areas coated with it are polished.
This process begins with washing the walls, using a soap solution. After waiting for the complete drying of the wooden facade after washing, proceed directly to the primer. A primer containing antiseptic substances in the component composition is used for such a process.
This is able to protect the tree from water entering it, which subsequently leads to the formation of mold. After the soil has been applied, it is necessary to wait until it is completely dry and continue facade decoration.
The main work on painting a wooden house
The process of direct staining should begin only after a few days, after priming the surface of the walls.
- pre-unpack the paint and dilute it to the desired consistency. Depending on the type of material, an appropriate solvent is used,
- then proceed to applying the first layer, for this use a brush,
- apply paint on the facade using a roller or spray. This can be done both in a single layer and in two or three layers. It takes at least 4 hours to dry one layer of material.
In addition to the fact that paint is an ideal option to create an individual and unforgettable house design or just to emphasize the naturalness of the materials from which the house was built, it is possible to provide him with all the necessary protective functions. The process of decorating the building is also quite simple, and it can easily be done with your own hands, without involving outside help.
Why protect wooden facades
It doesn’t matter if the house is lined with a construction board according to the curtain wall system or is entirely assembled from timber, the wood used in street decoration requires protection. There are objective reasons for this, any wood material has the following unattractive properties:
- flammability and excellent combustibility,
- porosity and, as a consequence, moisture saturation,
- deformation under the influence of various temperatures,
- susceptibility to mold and mildew, as well as pest bugs.
Unprotected wood will dry up over time, lose its attractiveness of texture and color (turn gray), become loose, and therefore not durable. That is why the tree on the facade should be protected from the following factors:
- UV rays
- high humidity
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 coatings (paints and varnishes).
Primer solutions or impregnations can be used as a preparation material for painting, and can also be a finish. 3 types of primers are divided:
- antibacterial (from 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, which include 2 mechanisms. Water-repellent soils, as a rule, protect against UV rays and strengthen wood.
On a note! All primers have a short life as a topcoat. Therefore, without further staining, the facade will have to be treated regularly every 2-3 years.
Impregnation treatment will not only improve the appearance, but also increase the life of the wood. For facade work, you should choose deep penetration compositions on an organic basis. Such solutions are usually toxic, have a characteristic unpleasant odor. When working with them, PPE (personal protective equipment) is used: gloves, glasses, a respirator.
On a note! Most primers have a transparent base, which means that treatment with such a composition will preserve the natural texture and color of the wood.
Any paintwork materials used for facade work must have a certain set of qualities. But in the situation with wood, this list is increasing, in view of the natural vulnerability of the tree.
Characteristics that any facade material should have:
- resistance to precipitation of various temperatures,
- resistance to temperature changes,
- color stability of the coating,
- abrasion resistance
- resistance to mechanical and physical stress,
- chemical inertness.
When it comes to painting a wooden facade, the paint requirements are complemented by the following criteria:
- Plastic. Wood breathable moving material. Logs and boards can change volume depending on the temperature and when the humidity level changes. Therefore, the material of the decorative coating should also be elastic and not crack.
- Vapor permeability. Decorative material should not create a barrier to moisture from the body of the wall, to prevent the onset of decay.
- Fire safety. The material itself should not only protect the wood from burning, but also be non-flammable.
On a note! When choosing a paint for work on a wooden facade, you should pay attention to the antistatic properties of the material. A paint coating with a high indicator will accumulate less dust and fine dirt, which means the facade will be much easier to maintain.
Classification of paintwork materials 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 resulting texture and the quality of the gloss.
The dull or luster 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 compounds. In addition, the glossy coating is more resistant to moisture and less susceptible 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. Gloss Degrees
|from 0 to 5||matte without reflection|
|from 5 to 10||matte with low reflection|
|from 10 to 30||semi-matte have some shine|
|from 30 to 60||medium gloss semi-gloss|
|from 60 to 90||glossy with gloss|
|from 90 to 100||super shiny|
All types of paints are diluted with 3 types of solvent:
- water, the compounds are called water dispersible,
- organic chemistry, such as white spirit, acetone, solvent,
- inorganic compounds.
Paints diluted with inorganic compounds are used very little 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 dispersible materials can be applied only at positive temperatures. Paints diluted with organic compounds can work with a slight minus.
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 formulations can be transparent, such as varnishes or dense, like enamel.
Types of paints
Before proceeding with the coloring of the tree, you should decide on which facade of what quality is planned to be obtained in the end. Modern paints and varnishes allow you to process wood and at the same time get different surfaces 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 formulations, their positive qualities and some disadvantages.
The most famous compounds 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-based paints based on drying oil are produced.
This paint has a very short 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 the appearance of rot inside the mass of the tree.
Among other things, such compositions dry for a very long time, about 10-12 hours. More suitable for maintenance of low buildings, fences or sheds, as they require regular updates.
Formulations based on resins with added oils. A wider circle is more understandable marking PF. The composition does not penetrate to a sufficient depth, forming a durable film on the surface. Dry faster than oil formulations but have a very unpleasant odor. They form a hydrophobic strong layer, which is not subject to fading from the action of 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 under the action of direct sunlight, and over time the surface loses its gloss. If it happened that the paint was applied to wet wood, the layer will begin to bubble.
Compounds based on organic compounds or resins. Well established in operating conditions in a humid climate. Coating with silicone (or latex) paint is durable even after applying one coat. The surface has a high degree of chemical inertness, the facade can be washed by 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.
In a special article, we will talk in detail about the advantages of silicone paint for the facade, and also consider the painting technology.
Popular paints for finishing wooden facades. Acrylic paint based on water dispersion is available for sale, that is, diluted with water and compounds based on an organic solvent. They have excellent adhesion, form a vapor-permeable layer resistant to moisture and ultraviolet radiation. That is, the coating does not fade, the color is not washed out by the rain, while the wood breathes. The paint is odorless and dries quickly. The protective layer is resistant to abrasion and has a long service life.
On a note! Acrylic compounds are available for sale that allow repair work even at low temperatures.
Such paints can be silicone, silicate and acrylic, what unites them is that they are all diluted to the desired consistency with clean water. Depending on the main substance, the price of a product can vary greatly. The advantages of such formulations include:
- absolute environmental 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 flaws are still present. Water as part of the dye penetrates the wood, so some surface mobility is assumed. Before applying the 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 existing house, you can do this yourself. To do this, you need to take care of the availability of free time, it will take a lot. Purchase consumables in advance: primer and paint in the right amount, coloring pigment (color) and solvent as needed. Approximate consumption rates of formulations and the service life of the coating in the table below.
Table 2.Consumption rates of compositions and the service life of the coating
|Type of paintwork||Consumption (g / m²)||Service life (years)|
|Silicone||150 - 200||20 and more|
|Alkyd||100 - 120||20|
|Acrylic||130 - 200||15-20|
|Water dispersible||110 - 130||20 and more|
In order to put the facade in order, in addition to materials, the following tools will be required:
- stepladder or scaffolding,
- various brushes in width,
- Angle grinder (grinder) with grinding discs,
- 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, glasses.
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.
Step 1. Removing the old coating.This procedure is performed if there is an old paintwork coating. It must be removed. To do this, you can use spatulas, a metal brush, sandpaper or a grinder with a nozzle. There will be a lot of dust, so work should be done with glasses and a respirator.
All work is carried out in dry, not hot weather. It will be necessary to protect the entire area of the facade, including the joints of logs or boards. In order for the work to be done efficiently and without delay, remove the gutter elements, shutters and platbands from the facade in advance. In addition to old paint, dust and street dirt should be removed from the facade.
Important! Do not leave old paint, even if the layer sits firmly on the surface. His life will expire, and he will peel off along with a new coating.
Stage 2. After the facade is cleaned of paint, the wood is polished and putty. If there is a place of darkening, or if foci of infection are visible, the top layer of the material should be removed to a clean texture. The rest of the surface is leveled. Existing surface defects are eliminated by puttying. Before proceeding to the next activities, the putty should dry. Putty material should be combined in composition with impregnation and paint.
Stage 3. 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 to preserve and emphasize the natural texture of wood.
Do not neglect the primer, impregnation will not only improve the quality of the wood, but will also increase the adhesion of the paint to the surface, while reducing the amount of material used. Even though the primers on wood are quite expensive, their use is justified. 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, take an interest in a long-term weather forecast. Rain is not suitable for painting, as well as heat. In addition, the work should be carried out in the daytime, when the dew has either evaporated or has not settled yet, that is, from 10 to 18 hours. The paint is applied in several layers along the fibers. Each next coat 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:
- If the facade has external metal fasteners, then before priming and painting they should be putty with an oil or acrylic composition to match the color of the wood. Such work will be especially relevant if the finish coating is planned to be made transparent.
- If you carefully approach the issue, then you can use several impregnating compounds, water-repellent impregnation is applied last.
- For better surface quality, after the impregnation dries, the wood should be sanded from fine roughness and lint.
Comparison of painting with other finishes
For analysis, we take the most popular materials and compare them according to the parameters most noticeable during operation. From the table you will see that paints for wooden facades are not a panacea for all occasions, but in many ways are better and more practical than, for example, siding or ventilated facades made of porcelain.
|Paint||Siding||Block house||Brick||Porcelain Tiles|
|Decorative properties||Perfectly preserves the texture and surface features of wood||Completely hides the base||High, imitates a rounded log||Completely covers the tree||Very decorative|
|Easy installation and application||Very easy to apply, only a brush or roller is needed||It is difficult to install, requires a special tool||Difficult installation||Sophisticated installation, concrete foundation required||Difficult installation|
|Cost||The cheapest finish||More expensive than any kind of paint||More expensive siding||One of the most expensive||Not inferior to brick|
|Durability||6-10 years||20 years||10 and more years||50 years||50+ years|
|The ability to hide design flaws||Practically does not hide||Hides completely||Hides||Hides||Hides|
|Weather resistant||High, but depends on the choice of paint||High||High||The tallest||Not inferior to brick|
|Resistance to mechanical stress||Resistant only to occasional scratches and bumps.||Does not protect, may collapse even with a slight impact||Average||High||The most durable finish|
It can be seen from the comparison that the most budget option is to paint the walls and other wooden elements of the facade. In terms of mechanical and fire-fighting properties, paint is inferior, for example, to porcelain tile or brick, but for the money that was saved when buying material and paying for professional builders, you can buy the most modern flame retardants that make wood absolutely non-combustible for several decades.
According to the results of a comparative analysis, you can make a choice in favor of paint. Now one more equally important decision should be made - what paint to paint the wooden house on the outside. Manufacturers produce dozens of varnish coatings intended for external woodwork, but only some of them can be suitable for a wooden house.
It depends on the:
- material of the house (beam, log, blockhouse, lining, chipboard, etc.),
- climate zone
- the kind of old finish
- the budget.
As for paint manufacturers, it is best to focus on well-known brands - Tikkurila, Duf, Finnkolor, Beckers, any of the brands included in the Akzo Nobel concern. But you should buy them in large retail chains or well-known online stores. Unfortunately, there are a lot of fakes and frank hack on the market now, so if you decide to save a few rubles, you risk spoiling your house and incurring significant financial losses - reworking poor-quality painting is a very time-consuming and expensive process. What paint is better to paint a wooden house outside can be found on the manufacturers' official websites, if there is no paint offered to you there, then you should not buy it, even at the most attractive price.
Antiseptic impregnations are often used to treat the walls of a house. They can also be justifiably considered full-fledged paints. Antiseptics are glazing and covering. Glaze antiseptics create a transparent coating that emphasizes the texture and color of the wood.
Coating antiseptics create an opaque coating on the surface, but retain the relief of the wood.
Antiseptics are very convenient for covering facades from planed or polished wood of valuable varieties, which have their own pronounced pattern and beautiful texture. Antiseptics are good because they penetrate deep into the massif of the tree. The compositions dry very quickly and in most cases for complete protection it is enough to cover the wood with two layers of impregnation. But such processing can only be performed on a fresh tree that has not previously been painted.
Antiseptic treatment should be repeated once every 2 to 3 years. But there are expensive tools that can be updated every 5-6 years. As a rule, they belong to the category of azure or colored impregnation and, together with the protective, perform a decorative role. The composition of many impregnations includes substances that inhibit ultraviolet light, the tree after such processing does not darken and does not change color.
Acrylic or acrylate paints
The most fashionable and modern paints for exterior decoration of facades. Produced in the form of emulsions and dispersions, water-soluble. In most cases, the basis of such paints are acrylic resins or acrylic copolymers. Artificial or natural rubbers, antiseptics, and fungicides may be added to the components. They are sold in the form of a white or transparent base with varying degrees of gloss - matte, glossy, semi-gloss.
A number of pigments and dyes have been developed for acrylic paints, with which they can be tinted in any desired color and shade. Some dye catalogs include up to 20,000 color schemes. But when buying such a paint, it is advisable to choose a pigment from a fan of flowers of the same manufacturer. Most factories keep the chemical compositions of their paints secret, so various reactions between products of different brands are possible.
There will be no explosion, of course, but the paint will dry for too long, go bubble or burn out quickly and change color. To avoid such "surprises", it is better to buy the goods of one brand or check the paint and pigment for compatibility. Most major stores will tell you what to mix with. It’s best to directly tint the composition directly in the store, especially if it has a tinting machine and a color studio.
- provide a wide range of colors,
- have excellent adhesion to wood,
- no smell
- absolutely safe in fire
- eco-friendly and non-allergenic.
But they have a significant drawback - they are quite expensive, at least significantly more expensive than alkyd and oil.
These are well-known compounds that have been used for painting wooden walls for many years. Created on the basis of polycondensation resins, united under the same name “alkyds”, paints are characterized by a relatively low production cost, excellent coating ability, and a high level of adhesion to wood. Moreover, you can paint as polished, planed or sawn wood, and logs, from which only the bark is removed.
Alkyd paints form a dense and durable highly elastic film that responds very well to temperature movements of wood and does not crack when dried, thermal expansion or other dimensional changes. When coating wood in two layers, the film becomes waterproof and slightly vapor permeable. Therefore, only dry wood is recommended to be painted with alkyd paints.
Some of the manufacturers include antiseptics and flame retardants in the composition of alkyd paints. Their presence must be found in the instructions for the paint before its use. If there are no such components, then the walls need to be further processed before painting. This slightly increases the cost of painting, but the life of the coating and the house as a whole increases several times.
Alkyd paints are usually available in a fixed range of colors, but changing the hue is quite simple - you need to mix two or more colors in a certain proportion so that the color changes in the right direction. The quality of the finish does not change. But, as is the case with acrylic, it is advisable to use only paints from the same manufacturer for mixing.
In recent years, the world's leading manufacturers have been offering colorless alkyd paints, which are tinted in the same way as acrylic. This is very convenient, especially when painting a new house, when the question is urgently, what is the best way to paint a wooden house from the outside, so that it stands out among the neighboring ones, even those built on the same project, which is often in cottage villages.
Alkyd paints are a full competitor in acrylic quality. They lose only in fire safety, and even then only during storage and work - rather strict rules of behavior with fire and heating devices are required here. But after drying, the paint layer becomes almost non-combustible. However, due to quick drying, the paint does not have time to deeply absorb into the tree, which negatively affects its durability. Alkyd paints have good frost resistance and are able to tolerate temperatures below - 30 0 C.
White spirit, solvent and similar weak organic solvents are solvents of paints on alkyd resins. They are moderately toxic and combustible, which also requires compliance with safety precautions when working. Хотя бензин и керосин тоже неплохо разводят алкидные краски, но их применение нежелательно — цвет при этом несколько тускнеет, а блеск может измениться в сторону повышения матовости.
For a long time, oil formulations, the diluent of which is drying oil or other natural oils, have been a serious competitor to alkyd. But in recent decades, an increasing number of manufacturers have abandoned them - paints are quite difficult to use, dry for a long time and the characteristics of the finish coating are inferior to most modern compositions.
Despite their shortcomings, these paints are the most budget option. After application to wood, the paint is well absorbed and creates a weathering resistant coating.
How to paint an old wooden house outside with old paint
There is only one recommendation - if the old layer holds well and is not covered with cracks and it does not show areas of film peeling, then you need to use the type of paint that was used previously. Alkyd can be confidently applied to oil paint - they blend well. But acrylic is not suitable here, although some manufacturers allow such contact.
In the event that you do not know what type of paint was previously used for painting the house, it can be determined by the appearance of the old coating. If the old coating has a leathery surface and grinds a little, it is most likely that the house was previously painted with acrylic paint. Acrylic paint cracks along the wood fibers.
If you can roll a small shred of paint into a tube, then most likely you are dealing with acrylic paint. If, when coagulating, a shred of paint cracks, then most likely it is oil paint. Oil paint forms a mesh crack during wear.
If the surface is covered with a glossy film of a glaze antiseptic, then the surface can be repainted with the same antiseptic or oil or alkyd paint. For repainting with acrylic paint, you will need to remove all the old antiseptic film to wood.
How to paint the walls of a new wooden house outside
Here, too, there are few recommendations - with acrylic or alkyd paint, if the tree is of ordinary species, glaze impregnation or azure, if the decoration is done with valuable wood with a good pattern. The primer is made only if it is provided by the manufacturer. In any case, you can paint the house outside only on a dry tree in warm weather, but not in direct sunlight. Any work on painting a wooden house should be done only when the wood is completely dry.
The best paints for facades of wooden houses
As you know, the facade is the main part of the house, and the impression of the building itself, and of its owner, is made just after a first look at the front of the building.
But the facade should have a good finish, not only because it is a “visiting card." The cladding has, of course, practical significance. It protects the facade from precipitation, sunlight and damage by insects and bacteria.
Due to the impact of all the above negative factors, the facades of buildings are destroyed. Moreover, this applies not only to buildings built for a long time and standing without repair for decades. Even the facade of a relatively young wooden structure can undergo such destruction if the paint for the wooden facades was painted of poor quality.
The front of the house is constantly confronted with negative environmental factors.
In good weather, it is ultraviolet and humidity. In other cases, wind, rain and snow. Therefore, for good facade protection, high-quality facade paints for wood should be used.
Paint for the facade of a wooden house must be selected taking into account the climatic characteristics of the region where the building is located. Temperature differences are a frequent occurrence in our latitudes and this also needs to be taken into account when choosing facade paints for wood.
If the paint for wooden facades, which was used in the decoration of the building, does not have good resistance to weathering, the destruction of the facade will occur faster. On the front of the house can go large chips. Therefore, for painting it is recommended to use the best facade paints for wood. The facade of a wooden house should also be correctly painted, the photo on the site demonstrates this process.
The main types of paint
In the decoration of wooden houses, different facade paints for wood are used. The main ones are:
Polyvinyl acetate (PVA) paint for wooden facades is used extremely rarely.
Although their cost is low, people are in no hurry to buy such facade paints for wood, as they resist very high humidity very poorly.
This paint for the facade of a wooden house improves its operational properties if polymers are added to it, due to which the paint resistance becomes more. However, acrylic facade paints for wood are always more durable.
Styrene-butadiene paint for the facade of a wooden house is also rarely used. In general, styrene butadiene provides good moisture resistance. However, paint for the facade of a wooden house, which includes this component, is used very rarely, because it does not withstand UV light. So paint based on butadiene, is used, as a rule, only during internal work.
Painting wooden facades
It is difficult for an inexperienced person to make the right choice of a particular paint for painting a wooden facade. Therefore, it is recommended that you familiarize yourself with the information on the various formulations in advance.
Of course, the sales assistant will always tell you what is best to buy for such and such a case. But knowledge of all the nuances will certainly shield from the wrong choice.
Paints differ, first of all, chemical composition. In particular, it is important which solvent includes the composition. Thus, in order to determine which paint is most suitable, it is necessary to clearly understand what kind of paint will be painted over it and how the climatic conditions of a given area can affect the protective layer of the facade. After finding out all these conditions, you have to choose from a much smaller number of options, which saves you time.
Most often, the manufacturer warns that such a paint cannot be used to cover a particular material or for outdoor work, for example, information on this is on the packaging with the paint. It is necessary to ensure that the selected paint is intended specifically for painting facades.
Even when choosing paint and varnish products, you should think about which composition is more suitable for painting the walls of your home. After all, the paint can be transparent, glossy, satin, matte or semi-gloss, etc.
It is also important what kind of coloring will be produced. This will be done for the first time, or the facade has already been painted earlier with one or another paintwork composition.
It is also important how much paint should be consumed, whether there are any features in its use. As a rule, all this is indicated on the package.
When buying paint, require a certificate confirming its quality.
Paint for outdoor woodwork: which is better
It can be very difficult to choose a composition for painting a wooden house, because there are many types that are suitable for this process. Each of them has its positive and negative sides, so the choice should be approached with full responsibility, errors will inevitably lead to numerous problems. Still, let's try to figure out which paint for outdoor woodwork is better.
Wood is a fairly common material for the construction or cladding of residential buildings. But over time, the details gradually lose their original appearance and are deformed. To prevent this, paints are used for outdoor woodwork. They are able to keep the coating in its original form, as well as give the surface the desired decorative appearance.
It must be borne in mind that all paints and varnishes that are used for wood must have a certain set of characteristics and perform the following functions:
- Prevent cracking. Under the influence of sunlight and precipitation, parts begin to change their structure, which leads to numerous deformations.
- Surface protection against microorganisms and insects. The fact is that a wooden coating is an excellent medium for the propagation of fungus and mold and is very attractive to insects.
- Abrasion resistance. This is the key to longevity.
- High-quality decorative component, which should not change much over time.
Thus, wood paints should provide the necessary protection and attractive appearance.

On a note! A good solution might be to use wax formulations. They perfectly protect the surface from moisture and preserve the texture of wood.
Water based paints
Currently, water based paint is becoming increasingly popular. This is due to the fact that such a composition is distinguished by excellent qualities, as well as good durability. There are several main varieties: latex, silicone, silicate and acrylic. It is the latter option that is most often used for painting a wooden house.
Front water-based paint Caparol
Acrylic paint for wood has many positive qualities. But special attention must be paid to proper storage, since at low temperatures the material almost completely loses its quality.
- Resistance to any environmental influences, especially to the sun. Due to this, the surface retains a shade much longer.
- An important parameter is excellent vapor permeability. The resulting coating does not allow moisture to penetrate from the outside and does not interfere with the steam exchange of wood.
- High covering ability. Almost always two layers are enough to get a beautiful and even surface, even when applied to a darker base.
- Elasticity. This is an important factor, especially when painting outside a wooden house. The fact is that the material undergoes constant compression and expansion, but due to its elasticity it does not crack or peel. Acrylic facade paint can be used even for recently erected buildings.
- Environmental friendliness. The composition does not contain hazardous substances that can affect human health. Also, the solution has no unpleasant odor.
- Quick drying. The mixture easily lays down and completely dries in 6–8 hours.
- Wear resistance. The coating is susceptible to serious mechanical stress, but is easily restored.

Due to the positive parameters, acrylic-based facade paint is one of the best solutions for painting a house.
There are certain features of working with the composition, which are recommended to be considered:
- If tinting is necessary, then it is advisable to carry it out at the place of purchase of products, this will allow to obtain a more clear shade.
- It is required to carefully calculate the right amount of material. Manufacturers place the consumption rate on the label, but it is an estimate.
- It is better to choose stores that work with trusted manufacturers to avoid buying low-quality products.
Thus, it is possible to obtain a wear-resistant surface with excellent visual effect, which will be protected from all harmful effects.
Rubber facade paints for wood are a modern material, in their properties slightly superior to the acrylic option due to the presence of special additives in the composition. Still such products are called latex.
- Complete safety for human and animal health. You can work with the solution without protective gloves and a respirator.
- Great durability. A wear-resistant film is formed on the surface, which well masks cracks and has elasticity.
- Vapor permeability. The coating does not prevent the base from breathing.

On a note! This is the best paint in the opinion of many experts, its characteristics are almost impeccable. But the cost of such products is quite high, which complicates the widespread use.
Features of choice
How to choose the best composition? To say that one product is far superior to another is wrong.
It is necessary to focus on the following parameters:
- Manufacturer. Preference is best given to trusted manufacturers who have a positive reputation. Finnish paints of two well-known brands have proven themselves well. Such material is notable for its quality and wide assortment. It is important to consider that it is the Finnish variety that is most often falsified, so it is better to avoid shopping in dubious stores and markets.
- Shelf life. This parameter is checked for sure, because over time the composition loses its quality.
- Price. Expensive is not always good, but it’s not worth chasing low cost.
- Features of the house. It is advisable to take into account the specifics of the material that was used for decoration, if the structure was not constructed of wood.
- Training. For each paint there are special impregnations and primers.
- Desired appearance. It depends on individual preferences.
Only after evaluating all the parameters, you can make the most balanced and correct decision.
Painting the facade of a wooden house - why, what and how to paint
Wood is still one of the most attractive building materials, combining the characteristic natural beauty, excellent heat capacity and ease of installation. But the facade of a building made of timber, logs and other types of wood materials (block house, plank, decking) requires high-quality protection in the harsh climatic conditions of Russia. The optimal solution is a specialized paint for the facade of a wooden house.
Why do I need to paint a wooden house outside
What are the requirements for a paint coat for a wooden facade? First of all, it is:
- Weather resistance - protection against moisture, UV rays, sudden changes in temperature, etc.,
- Biosecurity . Mold, fungus, insects spoil the appearance, destroy the house inside and out, often irreversibly,
- Durability . The coating should function properly for at least 5-7 years with proper application. Professional series guarantee coating resistance up to 10 years,
- Safety for others. Paints from unknown manufacturers often contain toxic substances such as lead and cadmium. You can get severe poisoning by them, not only during the application process, but also in the next 1-3 months, until the toxic fumes disappear.
Do not forget about the decorative function of paintwork. Paint for a wooden house in soft pastel tones gives airiness, lightness to the structure, dark saturated tones ennoble the wood, giving the building a solid look.
Types of facade paints
Facade paint for wood is a composition consisting of pigment, additives and binders, oils or polymers that create a protective and decorative layer on the surface. According to the basic composition of the elements are distinguished:
- Oil - paints based on natural or synthetic oils. They create a vapor-tight, dense film, quite resistant to abrasion and to mechanical damage.
When applied from the outside, they do not differ in durability, they quickly fade under the influence of sunlight, exfoliate. This is a relatively inexpensive tool for temporary painting.
Durability is ensured by compliance with the application technology, but the appearance worsens over time - the coating burns out and fades.
The first two varieties of coatings can be applied to any surface. The latter is preferably applied to previously unpainted wood.
How to choose the best paint for the facade
The choice of paint for the facade of a wooden house depends on several factors. The first thing to remember always is that the tree “breathes”. Of course, not in the literal sense. The term in this case means that the material has the property of seasonal expansion-contraction (the result of changes in temperature and humidity). Because of this, the vapor-tight film of oil and alkyd compounds does not hold well on the wooden facade - it cracks and peels off after 1, maximum 3 years of operation.
In addition, to update the paint layer is not enough just to go outside again with a brush or roller. A labor-intensive preparation method is required - to remove the old layer, sand, degrease, etc. To cope with similar on the facade of a two-story house with high gables is not easy.
The second prerequisite for a specialized composition is the presence of fungicidal and antiseptic additives that protect the facade of wooden housing from rot, mold, wood borers (ADLER Pullex Aqua-Color, Dulux Facade). And UV filters protect the coating from fading and tarnishing.
As a rule, preparatory impregnations already have a complex of similar additives, but in this case the rule “the more the better” applies.
Separately, mention should be made of the possibility of machine or manual tinting. In particular:
- No pigments can be added to oil-based paint for facade painting. Исключение составляют отдельные серии специального назначения (Dulux Domus, Tikkurila Teho),
- Алкидным акриловым краскам любого производителя легко придать нужный оттенок при помощи специальных тонировочных колеров. Например, Тиккурилла Пика-Техо колеруется в 120 стандартных цветов каталога, а Dulux Domus Aqua – более 400.
For many buyers, price becomes a decisive factor, but such an approach, as it very often happens, does not justify itself. The fact is that paint is characterized by such characteristics as hiding power and consumption.
Hiding power - this is the thickness of the layer and the density of the composition itself. Products of famous brands are applied in 1-2 layers without streaks and creates a dense uniform coating. Cheap paints, as a rule, are very liquid, they need to be applied 3-4 times to get the result, at least not worse.
Consumption means, for how many square meters one liter is enough - the greater the difference, the more economical the paint. For example, 1 liter of Novobychim for wooden facades can be painted up to 5 square meters. m. of the facade, and Osmo Landhausfarbe - not less than 8 square meters. m. in one layer.
Requirements for facade paints
The house on the plot is built, now it will protect you from the cold and bad weather. But in order for him to be able to protect you, it is necessary to protect, first of all, himself. Wood is a durable material, but very susceptible to destruction. Rain, frost, and temperature changes will quickly turn even boards and rounded logs into a cracked, crumbling mass. In addition, the house must have its own color. When you see a building, you will first remember its color. And then - how many windows, doors, floors are there.
Painting for home is clothing: it decorates and protects.
Other wooden structures also need painting. Especially if they are located in the open air: structures on playgrounds, wooden bridges, garages, warehouses, baths, etc.
Conventional coloring compounds will not work here. We need specialized ones that must meet the following requirements:
- durability. Who in our time needs to repaint a building every year?
- protection of wood against corrosion. The composition must preserve the wood in its original form, avoiding cracks, swelling, shedding.
- ability to hold color for a long time (usually achieved by the presence of a UV filter). Can you imagine the disappointment of the owner who bought bright purple paint for his house and a year later saw that under the influence of the sun and rains the color became pale and barely noticeable?
Modern facade paints contain, among other things, antiseptics, flame retardants, water repellents. Oddly enough, anticorrosive facade coatings were invented for a long time - even in Ancient Russia. Modern scientists only refined the technology, but almost did not change it. The long history of facade painting mixtures is explained by the fact that in Russia, wood was the main building material due to its abundance in this territory. Plus, many years of shipbuilding experience: wooden ships most of all needed external processing.
