Usually fresh material crumble within a year. The very fact that spalling did not affect either the strength of the wood or on its other properties, it only spoils the appearance of wood surfaces. If you delete the top layer, the tree will once again its original appearance. Prevent this phenomenon can be a timely application of antiseptic or refinishing. Much more dangerous for wood is the so-called "Blue." It occurs mostly at high humidity and temperature 10-25o C.
It promotes the emergence of blue and the stillness of the surrounding air. Crude, svezhespilennaya wood is more susceptible to blue than The dried. However, the dry wood may turn blue in the presence of the above conditions. Heavily exposed to blue pine. The very blue, contrary to popular belief, does not alter the mechanical properties of wood. However, it is a precursor of rotting wood (the defeat of the fungus and other microorganisms), and its presence indicates the excessive humidity of the material. Proper design of structures, the protection of wood special structures and regulation of humidity (with ventilation) can prevent the emergence and impact of destroying microorganisms. The worst enemies of wood are fungi, mold, bacteria and antimitsety (a cross between fungi and algae).
They not only detracts from the appearance, but also destroy the fibers and softening the wood, causing irreparable damage to joists. Professionals are distinguished types of rot (the result of exposure to wood micro-organisms) by color (red, white, gray, yellow, green). Red rot affects coniferous wood, white and yellow – an oak and birch, green – with oak barrels, as well as wooden beams and floors cellar. The worst enemy of the houses is a white mushroom house. In one month he can "eat" chetyrehsantimetrovy oak floor. Earlier in the villages of the house, which hit the fungus, burned immediately to save from getting all the other buildings.
