Wood is the main material in the construction of country houses of country type. The material is lively, easy to process, the wooden house is warm in winter and cool in summer. However, the wood has several enemies, from which it can seriously suffer. These are, first of all, fungal populations that live and reproduce on the wet, undried surface of the wooden structures of the house. Fungi affect the wood and within three or four months it is turned into rubble. In such cases, urgent impregnation of wood from decay is required. The process of decaying the damp wooden parts of the house is fleeting, and if it has begun, it can no longer be stopped.
Another dangerous enemy of wooden houses is the beetle-borer. They can also be saved by impregnating wood. Zhukov several species, but the work of pests perform one, turn wood into powder. The principle of action is the same for all: beetles gnaw through numerous twisting passages in the thickness of logs, beams and boards. The tree is planned, but inevitably attacked, and victory always remains for insects. And woodworms bite only in dry material, which is easy to grind. Thus, a damp tree is rotted, and dry bark beetles are destroyed. Is there a way out of this vicious circle?
It is necessary in time to prevent the invasion of fungi that cause decay, and raids of beetle-borer, turning wood into sawdust. This is done by impregnating the wood, 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. Dry the wood, and then impregnate it with special compounds that will create protection from decay and destroy insects.
There are two main types of drying: natural drying, in which the boards and logs are stacked under a canopy, counting on blowing by wind for two to three months. This method does not guarantee complete absence of fungi, as the process is too tight.
The second way of drying is to place the sawn timber in a special drying chamber. For several days in the chamber, forced heating up to 80 degrees is maintained with a constant circulation of hot air. As a result of this drying, the occurrence of fungi is almost completely eliminated, and the materials remain dried for a long time. Now for already conditioned lumber, having a moisture content of 20 percent, impregnation of wood with antiseptics is carried out. There are a number of different antiseptics - these are water-soluble and oily preparations. The latter are unsuitable for use in enclosed spaces and are purely industrial due to their high toxicity.
Therefore, the most affordable antiseptics for your sawnwood will be water-soluble. This is sodium fluoride or sodium silicofluoride. Both antiseptics have a powdery consistency and are used in 4% solution. There is one more preparation with which help impregnation of wood can be made: ББК-3. It is characterized by a complete absence of toxicity and is readily soluble in water. All antiseptic solutions can be successfully used for surface treatment of sawn timber. Apply antiseptic followed by copious spraying of the surface of the wood from the spray gun or by spreading with a wide brush. It should be remembered that the more layers are applied, the more effective the antiseptic will be and the deeper the preparation will penetrate into the thickness of the wood. Only deep impregnation of wood can protect your house from harmful insects and fungal mold.
