Wood is an excellent material that has an attractive appearance, original shades and texture. It can be called really the best building material. However, with its considerable strength, builders in most countries have been using a special coating for many years already, which makes it possible to greatly improve the characteristics of wood - wood varnish. The choice of this composition depends on what requirements are imposed on it.

Types of varnish depending on the purpose

For the glazing of wooden surfaces it is customary to use water-borne varnishes, as well as compounds that are made on the basis of organic solvents. They are the most hygienic. In addition to coating compositions, there are also those that are designed for protection. Wood varnish, consisting of alkyd resins, vegetable oils, modified fatty acids, as well as having a special tallow composition with the addition of a desiccant, is aimed at coating oil paints, furniture and light wood. A protective coating on any kind of wood can be created by using nitro-lacquers. They are made from colloxylin, cellulose, alcoholic, complex ketone and ether solvents. Such varnish for wood differs the raised stability to gasoline, mineral butters, however it is unstable to an ultraviolet and alkali. It should be taken into account that such compositions have limited water resistance, so they are not recommended for coating wood in damp areas.

Thanks to the polish, a transparent, shiny, hard coating that dries in an hour, and also emphasizes the texture of the wood, is formed on the surface. Impregnation of wooden surfaces is carried out using bakelite varnishes. The use of such formulations involves coating in several layers, each of which must dry for 2-4 hours, and finally all should dry up 120 hours. Oil-resin varnish for wood is designed for surface treatment of chipboard.

Oily formulations can have a different ratio of oil and resin, so they are divided into fatty, bold and lean. They are usually used to cover the floors. Waterproof varnish for wood has a special structure, not allowing moisture to penetrate inside, which helps to protect the surface from negative factors. The choice of a certain type of composition depends on its purpose. For internal work should be selected safe compounds, and for outdoor - especially resistant. To choose the best varnish for a tree, these and other factors must be taken into account.
