Working with tree, masters seek to keep its texture as much as possible. It is possible by means of such means as varnish. Structures for covering of wood make on different basis therefore their properties, as well as the drying period, are not identical.
Lucky for tree are good the fact that they do not hide, and opposite, emphasize her. But it is peculiar only for transparent or very light structures, color give to tree shade. Varnishes make on water, spirit, polyester, acrylic, cellulose, polyurethane, oily base.
What varnish for tree to choose?
Varnishes for water-based tree are odnokomponetny. These are the most dolgosokhnushchy structures among all types of these coverings for wood. They can be diluted with water, are simple in drawing, are suitable for all types of works.
Varnishes on the basis of polyurethane are inexpensive and quickly dry. They are as one - and two-component. Some of them demand preliminary priming of the processed surface. These structures dilute with solvents therefore they have quite pungent smell. Are mainly used in furniture production. From shortcomings of these means of processing of tree it is possible to note availability of hazardous substances. Nitrolacquers make on the basis of cellulose. It is, perhaps, the most popular type of varnishes, the reason for that – small time of drying and low cost. But these structures have essential shortcomings: low resistance to abrasion and ultraviolet, possible spalling. Acrylic lacquers are more expensive than the fellows, but are often used in production of furniture because of the excellent light resistance, durability, qualitative gloss. These structures very long dry that does not prevent them to be the most popular among those who are keen on decoupage. Varnishes on the basis of polyair are used quite seldom because of complexity of drawing and high toxicity. They are sprayed in the form of aerosol and demand special purpose tool. These structures use at production of musical instruments as they are capable to create quite thick coating layer.
What varnishes on tree will be suitable for external works?
For external works use frost-resistant, light-resistant, moisture-proof coverings. Only such varnishes are capable to protect wood from impact of precipitation, winds and sunshine reliably. It is impossible to apply to processing of tree which is on the street, the structures forming inelastic film. Nitrolacquers belong to them. In addition, varnish for external works has to contain the anti-bactericidal additives protecting wood from insects and preventing decay emergence. For external works it is possible to use varnishes on acrylic, oily, water base. The most worthy among these coverings consider high-strength yacht varnish. Structures for external works of the brands "Hello", "Akwa", "Rastsvet", "Eurotex", "Bor" are most popular.
