Country wooden housing construction is actively developing. The number of people who dream of living in a house made of natural material saturated with the energy of a living forest is growing. But wood without proper processing is very sensitive to atmospheric influences, after 2-3 years traces of destruction may appear - mold, fungi, damage by woodworms. How to paint a wooden house from the outside in order to maintain an attractive appearance for a long time and increase the service life of the structures?
The structure of wood consists of tubular fibers, which swell when moistened, lengthen, and when dry, on the contrary, shorten, decrease in volume. Cyclic changes in conditions lead to the formation of cracks in the tree - an entrance gate for various fungi and pests. Also, when shrinking, lumber can lose geometry, twist or bend.
In order to significantly reduce the impact of harmful factors and at the same time emphasize the beautiful structure of the tree, protective and decorative means are used. Even in ancient times, people noticed that some substances slow down the processes of natural destruction of wood. At first, natural resins were used, and with the development of technologies, synthetic-based paints and varnishes, which are not inferior to natural analogues or even surpass them in a number of qualities.
The choice of protective and decorative compositions is huge today - impregnations, oils, waxes, paints, varnishes. But not all of them are suitable for outdoor decoration. It is important that the product creates a coating on the surface that is resistant to sunlight, fluctuations in temperature and humidity, and mechanical damage. At the same time, the content of a certain amount of toxic substances is allowed in materials for external processing, since they provide a preserving and disinfecting effect. Some of them penetrate into the thickness of the tree, while the rest wears off and does not pose a threat to health.
Means for interior decoration, on the contrary, they should be as harmless to humans as possible. It is optimal if they do not seal the pores of the wood and maintain its vapor permeability. Thanks to this valuable property, the walls can "breathe", providing a favorable microclimate in the room.
There are several groups of products for external wood processing:
Often several properties are combined in one composition. This allows you to get the desired effect without unnecessary labor and material expenditures. Among the most famous and popular brands that produce paints and varnishes for wood are Tikkurila, Penetex, Belinka, Senezh and others.
