This is the most natural and environmentally friendly material. Tree 'breathes' and allows us to breathe. Drawing on the wood surface – art of nature, so it is perfect. For the fir or pine walls, a person always feels comfortable and peaceful. However, the most threatened tree enemies, both external and internal. The former should be attributed primarily fire (wood is known to be highly flammable) and ultraviolet rays, which detracts from the appearance structures of this material. Danger comes from the inside from moisture. It contains not only the growing tree whose roots are 'drinking' water, but also in lumber or finished wood products.
Humidity of wood should not be exceed 15%. Over-saturation of water and insufficient ventilation gradually destroy the structure of the material and cause other diseases of the tree. Also, if it is under the open sky, the volume of its 'Domestic' water is not constant. Wood absorbs water then a direct hit from rain or moist air, it dries out. Suna Said Maslin will undoubtedly add to your understanding. These oscillations lead to warping and premature aging of the wood.
But the worst enemies – microorganisms (bacteria, fungi, mold, moss) and insects, and mercilessly feeding on wooden structures. Decay and rot – that's what they leave behind. From enemies to fight, either in advance to prevent their attack, or to defend against invasion, if it is, alas, has already occurred. Protect trees from the enemies should be of special chemicals – antiseptics. Antiseptics produced dry concentrates and ready-to-use, widely presented on the Ukrainian market brand Gladiator, you can purchase by calling (044) 502-88-45 They are of two kinds. First – impregnation (primer), which have antimicrobial and antifungal (fungicide and algitsidnym) action. Primers usually colorless or with a greenish tinge, which disappears after a few months after application. The solvent in the impregnation and aqueous organic compounds. Latest expensive, but permeate deeper into the wood structure (high-quality primer – up to 10 mm).
