Therefore, no claim to full accuracy, but only for readability, we divide all paint materials for the processing and protection wood surfaces and products to the following groups: special protective materials * varnishes * tinting compositions * paint. Angel investor addresses the importance of the matter here. Special protective materials are intended primarily to protect the exterior surfaces of adverse environmental impact. If this has piqued your curiosity, check out Mashable. Although the need to protect both external and internal wood surfaces. These special materials can be divided into two broad categories: antiseptics and flame retardants. A wood preservative – it is a special chemical substance, which has antimicrobial and antifungal (anti) effect. Antiseptics used to protect wood from biological enemies, should be persistent, do not absorb moisture and are not washed away by water. In addition, they should be relatively safe for humans and animals, shall not release toxic substances during operation and odors, and do not hinder the subsequent processing or painting wooden surfaces.
Currently, widespread water-soluble antiseptics, as well as compositions, where the diluent used white spirit, at least – turpentine. There preservatives and oil-based, such as creosote, which is impregnated railroad ties, but such compounds has a strong unpleasant odor. Antiseptic treatment of wood materials and products can be produce at the factory by impregnating baths, under pressure or at the construction site during the installation or finishing. For example, the Danish solid wood parquet hardwood JUNCKERS first dried in special chambers under high pressure, and moisture content in solid wood is reduced to zero. Then the tree throughout the depth of antiseptic impregnated, through this wood gets artificial moisture 5-7%. In the case of antiseptics and preservatives in finishing work to maximize the protective effect of the whole should produce a protective timber treatment after Planing, milling, drilling and stripping, but before assembly of wooden parts in the product. Under the influence of precipitation, and UV-untreated wood, originally having a white-yellow, gradually begins to turn gray and chip.
