Wood varnish for outdoor applications gives a glossy shine to the surface of the product and enhances the beauty of the natural material. This coating also protects the surface from external influences and mechanical damage and allows you to save the texture of the tree for a long time.
Where to start the choice?
According to the field of application, varnish for wood is distinguished for external works and for internal ones. In the first case, compositions are used that form an elastic film, which is highly durable and will not crack upon deformation of a wooden surface. Such varnishes have good resistance to temperature changes, moisture and ultraviolet radiation. For internal work, on the contrary, a hard coating is required, which has an increased resistance to abrasion. This is the difference between them, since the hardness and elasticity of the film are completely opposite concepts, and it is impossible to combine both of these requirements in one composition.
The outdoor varnish contains special components that protect the tree from the damaging effects of sunlight, as well as some additives that prevent mold and mildew. As a rule, wood varnish for outdoor use is used in the decoration of garden furniture and other products that are used outdoors and are constantly exposed to cold and heat, snow and rain.
Wood varnish (the price of this finishing material is widely represented in specialized catalogs) is divided into categories and the degree of gloss that it gives. There are high-gloss, glossy, semi-gloss, matte or semi-gloss varnishes. This factor does not affect the protective characteristics of the composition, therefore, when choosing a varnish according to the degree of gloss, it is worth starting from personal preferences. On sale today you can find both colorless and colored varnish for wood for outdoor use. However, if desired, tinting the colorless composition in almost any shade is possible.
