Competently executed painting of the facade of the building can transform a nondescript wooden house into a beautiful "teremok" that impresses with its artistic style. To form the external appearance of a residential building, a wooden house is painted, the paint for which is selected in strict accordance with the type of material from which the structure was built, and the conditions of use - for painting the house from the outside or from the inside.
Even a small country house is transformed after painting
You can paint a wooden house with various types of paints and varnishes (hereinafter referred to as paintwork materials), since the performance characteristics of paints for exterior and interior work are different. The attractiveness of the building and its durability depend on the quality of the painting of the facade of a wooden building.
Causes of wood aging in wooden houses
From time immemorial, wooden houses have been serving people, protecting them from cold, rain and wind. At the same time, the building is exposed to negative environmental influences, leading to the aging of wood and the deterioration of its properties as a building material. The centuries-old practice of operation has determined the approximate period of wear of wooden residential buildings, not exceeding 80-85 years.
The main natural factors that age the natural wood of the facade of buildings are:
direct sunlight, mercilessly drying wood fibers. Dry fibers lose their elasticity and strength, change their position, become sharp. The surface becomes rough, begins to actively absorb sedimentary moisture, burns out and becomes covered with dark spots;
sedimentary moisture, provoking deformation and swelling of the material;
That's what will happen if you don't take care of how to beautifully paint the wooden house outside, the photo below is not the worst option.
An unprotected wooden surface quickly begins to deteriorate.
temperature changes are the worst enemy of any building material. With a sharp cooling, the moisture that fills the pores of a damp tree freezes, turning into a crystalline state. Ice crystals expand the fibrous structure of the tree until the individual fibers break. When drying, the fibers narrow, which, with repeated cyclic repetition, leads to cracks;
wood that is not protected from moist air is prone to rotting, mold and fungal deposits;
wood-boring insects such as bark beetles, which grind wood and destroy the integrity of the tree structure.
Additional protection of a wooden house when painting
There are plenty of factors that cause wood aging and premature wear at home. To preserve wood in its original natural state, it is necessary to comprehensively protect the surface of wooden walls with special chemical compounds:
flame retardants - to protect against fire;
moisture-repellent agents - to protect against moisture;
antiseptics - to combat fungi, mold and other biological pests;
insecticidal preparations - to combat the invasion of carpenter insects.
Similar formulations are usually sold in standard containers.
A worthy and convenient alternative to the use of protective chemical compounds is painting for the facade of a wooden house, which achieves the same effect, similar to the use of a whole complex of different preparations. At the same time, painting a wooden house from the outside performs a wider range of tasks compared to the monofunctions of each protective solution separately, since, along with maintaining the quality of the wooden facade, the paintwork coating pursues decorative purposes. Using a variety of options for painting a house, you can significantly transform the look of the old facade and the entire wooden structure.
Requirements for paints for a wooden facade
Distinguish paints for internal and external works. Coatings for outdoor use have a wider temperature range of use, they are more moisture resistant. Compositions for painting interiors should be safe for people and pets, have no unpleasant odors, and be highly resistant to abrasion.
Initially, the facade of a wooden house was painted with paints for outdoor use. When the improvement of the facade by painting became popular, paint manufacturers instead of “outer” often began to write “facade” on the packaging. Over time, the second name stuck and began to be used even more often than the original.
Paint "Facade" and "For outdoor work" is one and the same
The following requirements are imposed on facade paints for wooden houses:
High adhesive qualities in relation to wooden surfaces.
Increased impact resistance and resistance to scratching and chipping, providing mechanical strength of the coating. The presence of increased mechanical wear resistance and resistance to abrasive wear from exposure to wind with dust.
Weather resistance, which consists in the ability of a paintwork coating to resist the destructive effects of bad weather and the environment. Here you can also add the requirement for the chemical inertness of paintwork materials in relation to alkalis and acids formed in areas with a high concentration of exhaust gases.
Hydrophobicity, providing water-repellent properties to protect wood from decay.
Resistant to sudden temperature changes of a cyclic nature.
Light fastness (resistance to ultraviolet radiation).
Good vapor permeability.
Preservation of elasticity after drying, compensating for microdeformations of facade materials during temperature changes.
Low dirt retention, resistance to repeated washing.
The ability to maintain color brightness for a long time.

Varieties of paints for painting a wooden facade
When choosing what paint to paint a wooden house on the outside, the following types of coatings are worthy of attention:
Antiseptic formulations
Able to impregnate the outer layer of wood to a depth of 4-7 mm for full protection against the negative effects of the environment, rot, mold and fungus. The industry produces two types of antiseptics:
coating antiseptics - opaque coatings that completely hide the texture of wood, while maintaining the surface topography;
glazing antiseptics - transparent coatings that preserve the natural pattern of the texture.
Acrylate coatings
They have excellent weather resistance and allow the wood to "breathe". Acrylate coatings do not interfere with natural air exchange through wooden walls. Acrylate paints have high elasticity, which allows the painted layer not to crack when the facade is deformed. In European countries, more than 80% of residential buildings are painted with acrylate coatings. Acrylic paints of different colors are mixed into homogeneous compositions, which makes it possible to obtain a color scheme of any desired color.
Oil paints
prolonged drying of oil coatings, exceeding 24 hours;
after coating with oil paint, the wooden surface becomes matte.
Oil paints are offered by domestic and foreign manufacturers
Alkyd coatings
Endowed with water-repellent properties. However, due to the rapid drying (20-30 minutes), the coating penetrates into the wood layers to a shallow depth, so alkyd coatings are short-lived. A distinctive feature of alkyd coatings is the ability to withstand low temperatures below 30 degrees below zero.
It is important! Any paint and varnish covering needs to be updated periodically. Having decided how to paint a wooden house outside, you should know the maximum period during which the applied coating may lose its original appearance and quality:
for antiseptics, the service life is from 5 years for glazing compositions and up to 7 years for coating antiseptics;
for acrylate materials - no more than 8-10 years;
for oil paints - up to 6 years;
for alkyd coatings - up to 7 years.
Optimum selection of coloring composition for the facade
Acquisition of facade paint from leading manufacturers does not yet guarantee high-quality painting of a wooden house. Paint for a wooden house on the outside must comply with the operating conditions of the building and the condition of the surface to be painted. For example, paints made in Spain or Italy are more adapted to the mild climate characteristic of these countries, while paints from Finnish or Swedish brands are designed for harsh winters.
"Southern" colors even look more "summery"
Oil paints are more appropriate when painting the outside of a wooden house over old paintwork, as wooden buildings used to be painted with oil paints, on which modern compositions do not fit well. It should be clearly understood that the determining factor in choosing paintwork materials for repair and restoration work is the type of binder, but not the solvent. Therefore, oil or acrylate paints can be applied to old oil paints or alkyd coatings without problems, however, only acrylate paints can be applied to old acrylic-based coatings.
Alkyd coating options are characterized by high frost resistance, they continue to perform their functions at frosts below -30 ° C.
Properly selected paint retains its properties in heat and cold
Acrylic paints are popular due to their ease of use, they can be diluted with water and applied in any way. When painting, you can get the shade of the desired color yourself. It is enough to purchase white paint as the base composition and special colorants, combining which, they get the desired color shade.
Manufacturers of facade paints for wooden houses
The leading brands among manufacturers of facade paints on the Russian paint and varnish market include:
Tikkurila (Finland) is a name that has become a kind of synonym for quality for any paint. The main consumer characteristic of coatings produced by Tikkurila is considered to be excellent hiding power. Tikkurila feels great on wooden surfaces of any configuration.
Alpina (Germany) is one of the leaders in the production of coatings, successfully competing with other "promoted" brands. The compositions have increased resistance to abrasion, temperature extremes. Clients are offered individual computer tinting to create an exclusive facade.

The general progress of the painting of the wooden facade
Painting a wooden house from the outside conditionally takes place in two main stages: preparing a wooden surface for applying paintwork materials and directly applying a paint and varnish coating.
Surface preparation
This is an important point that determines how to paint a wooden house with the maximum protective effect. Applying paint to an unprepared wooden surface is highly undesirable, since conditions for good adhesion of paintwork materials will not be provided and the rules for processing wood from negative biological influences will not be observed. Preparation of the surface for painting consists in carrying out the following activities:
if the building is new, then it is enough to clean the wooden surface from dust and dirt with any improvised means.
if it is required to paint the facade of an old building, then the remnants of the old paint and varnish coating are first removed and traces of mold are destroyed;
Old paint is cleaned as thoroughly as possible
damaged areas of the wooden surface are repaired, all irregularities are cleaned, cracks are puttied;
nail heads, metal inclusions are coated with a metal primer;
it is desirable to carry out finishing alignment with a primer.
It is important! Upon completion of the preparatory measures, it is recommended to leave the treated surface for several days until it dries completely with the provision of high-quality ventilation.
Application of coatings on the prepared facade surface
It is carried out in the following sequence:
wood is impregnated with a primer antiseptic in order to enhance its protective qualities and improve adhesive ability;
a topcoat is applied, consisting of a layer of primer on wood and several layers of paint, with a time interval that guarantees complete drying of each previous layer.
Painting a new and old surface is carried out in the same sequence, but several nuances should be taken into account:
the facade surface of the old building must be painted with the same type of paintwork that was originally used;

Visually the process of painting a house on the video:
When painting the exterior wooden surfaces of a residential building, it is recommended to “listen” to some advice from experienced craftsmen.
Paint is applied only on a dry surface. When painting in several layers, an interlayer exposure is observed, which is 24 hours for alkyd compositions, and from 2 to 12 hours for water-borne compositions.
LKM is applied in a direction longitudinal with respect to the fibers.
Exterior paint consumption will noticeably decrease if the surface is primed.

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