Wood is the main material in the construction of suburban country houses. The material is alive, lends itself well to processing, in a wooden house it is warm in winter and cool in summer. However, wood has several enemies from which it can be seriously affected. These are, first of all, fungal populations that live and multiply on the wet, dry surface of the wooden structures of the house. Mushrooms infect wood and turn it into dust within three to four months. In such cases, urgent impregnation of wood from decay is required. The process of decay of wet wooden parts of the house is transient, and once it has begun, it is already impossible to stop it.
Another dangerous enemy of wooden houses is wood-boring beetles. Impregnation of wood can also save them from them. There are several types of beetles, but pests do one job, turn wood into powder. The principle of operation is the same for everyone: beetles gnaw through numerous winding passages in the thickness of logs, beams and boards. The tree is systematically but inevitably attacked, and the insects always win. And the woodworms biteonly in dry material that is easy to grind. Thus, a wet tree is prone to rotting, and a dry one is destroyed by bark beetles. Is there a way out of this vicious circle?
It is time to prevent the invasion of fungi that cause decay, and the raids of wood-boring beetles that turn wood into sawdust. To do this, wood is impregnated, but first the lumber should be dried. It is better to comprehensively process the material prepared for building a house, and only then begin construction. We dry the wood, and then impregnate it with special compounds that will create protection against decay and destroy insects.
There are two main types of drying: natural drying, in which boards and logs are laid out in piles under a canopy, counting on wind blowing for two to three months. This method does not guarantee the complete absence of mushrooms, as the process is too long.
The second drying method is to place the lumber in a special drying chamber. For several days, forced heating up to 80 degrees is maintained in the chamber with constant circulation of hot air. As a result of such drying, the occurrence of fungi is almost completely eliminated, and the materials remain dried for a long time. Now, for already conditioned sawn timber with a moisture content of 20 percent, the wood is impregnated with antiseptics. There are a number of different antiseptics - these are water-soluble and oilydrugs. The latter are unsuitable for indoor use and are purely industrial due to their high toxicity.
Therefore, the most affordable antiseptics for your lumber will be water-soluble. It is sodium fluoride or sodium silicofluoride. Both antiseptics have a powdery consistency and are used in a 4% solution. There is another preparation with which wood can be impregnated: BBK-3. It is characterized by a complete absence of toxicity and is highly soluble in water. All antiseptic solutions can be successfully used for surface treatment of lumber. The antiseptic should be applied by plentiful spraying of the wood surface with an airbrush or by smearing with a wide brush. It must be remembered that the more layers are applied, the more effective the action of the antiseptic will be and the deeper the drug will penetrate into the thickness of the wood. Only deep impregnation of wood can protect your home from harmful insects and fungal mold.
