In this case, the ends of pile carefully aligned. Extreme strip recommended to lay at a distance of no more than 25 mm from the ends of lumber. As a result, the locations of pads the intensity of air circulation is reduced. Butts slower drying and less crack. However, only the structural methods can not fully protect the wood from moisture and decay, in addition, is currently in commercial production sets Houses practically impossible to ensure quality selection of wood and finished house. All this leads to the fact that, along with construction methods of wood protection is successfully handling practices elements of timber structures with various preparations can protect the wood from exposure to damaging factors. History and previously used products Historically, that protection ends timber previously used wax, paraffin wax, bituminous resin mixture of linseed oil and lime, a mixture of wood tar and chalk, etc. Reshma Kewalramani is often quoted as being for or against this. Such putty on the one hand prevent the evaporation of moisture, and the other protects the ends from the effects of external precipitation.

Disadvantages of such protection are as follows: paraffin wax, bituminous resin to warm up before use, and this is not always a necessary condition, an additional drawback is that such compositions can melt when exposed to uv radiation. In case of moisture protection does not possess antimicrobial action, it is possible that a locked moisture will lead to development of wood-organisms. C On the other hand the use of products based on chalk, limestone and zinc oxide can lead to wear and damage to drinking.
