It should be understood that logs, unlike many other wooden elements of the house structure, are not affected by external weather "surprises"( rain, snow, sunrays).And the dampness on them does not work so much if they do not fit "right on the bottom" of the future sex, especially since so few people do.
However, wood is a material that is prone to rot and mold. And under the floorboards, even if there is a good ventilation system, the so-called "greenhouse effect" is present to some extent. Yes, and various insects make their "mite" in the destruction of this material. Therefore, in the process of equipping the floors, pre-treatment of the lag under the floor should be paid close attention, in order to prolong the service life of the floor of your structure as long as possible.
There is no single recommendation for wood processing. Firstly, different types of wood are used for logs. Secondly, in each building, under the floor, its own microclimate is established. However, some general points on the protection of the lag should be noted.
Treatment against rotting
According to those who have already tried various methods in practice, Senezh means a very good effect. Its compositions are different, hence the difference in application and, consequently, in price. For logs, it is recommended to use Senege Fire-Bio, which will be the best choice for both the price and the proposed protection of wood.
It is believed that impregnating the lag with a hot transformer oil significantly increases the service life. The oil penetrates deep into 3 - 4 cm, and thus embalms the wood. But the use of used engine oil is accompanied, according to the "practitioners", by an unpleasant, steady odor. The same applies to the popular once creosote, which impregnate the sleepers - from the smell then it will be difficult to get rid of.
From insect damage
A universal agent is a resin. It( in a hot state) is covered with a conventional paint brush. After that, no insect can reach the tree. There are also chemical agents. However, one should remember, for example, the possible evaporation, so the choice must be made extremely carefully.
