Graying wood


If the timber is exposed to the influences of external conditions

Is graying wood indicative of wood decay?
The graying, fading or discoloration of the timber, (καυσοξυλα) as some call this process arises as a consequence of a natural process, if the timber is exposed to the influences of external conditions. Takes the graying also affect the quality of wood? The graying of the wood interacts with the wood like a protective layer against external influences. With the graying of the wood protects itself against UV rays, heat and humidity differences. Chemically untreated, but naturally treated wood turns gray after a few years. This protective patina has a thickness of 2 to 3 mm and unabgesehen of different opinions about their aesthetics, it is the most effective and natural wood preservative. After the initial 2-3 millimeters of Holzvergrauung faces this "wood decay", and precisely this patina protects for several decades the healthy wood core effectively, without compromising the natural interaction with the environment (wood respiration, permeability) to prevent.(ξυλα για τζακι)
How to prevent the Holzvergrauung? 
Graying wood
The Holzvergrauung we can resort to the outer surfaces of your log cabin already at the first application of protective varnishes.After treatment with boric salt followed by a coat of boron compounds, linseed or other natural impregnating oils, which we narrow the natural pigments of the desired color. In this way, the block houses allows to develop their protective layer through the natural graying, but at the same time to hide the gray behind the pigments of the first impregnation. (καυσοξυλα)
How can the gray of the wood are removed in a natural way?
Many homeowners would block access in this case, a paper cutter. By grinding, we destroy the wood effectively protecting protective layer of graying and unnecessarily we reduce the thickness of the beam.Already graying wood recommended again with a, with a strong and the desired color pigments LABEL FOR, impregnating natural origin to coat.(χαρτοκιβωτια If it is possible we try to avoid a Holzabschleifen; unless that the wood had already outlived its usefulness. Before impregnation, it is advisable to treat the wood again with boron salt. This is especially true if we do not know whether the blockhouse has previously been treated with boron salt.( μεταφορες μετακομισεις  )
