13 Translate into Russian without a dictionary: paint and varnish removers

Chemical paint and varnish removers are available in a variety of semi-paste and liquid forms. Almost all chemical removers are referred to as "paint removers" or "paint strippers." There are several basic types of paint removers:

• Liquids are primarily for clean coatings and removing one or two layers of paint. This formula dries too quickly to remove multiple layers of paint. Good for detail areas or irregular surfaces. Also good for the stubborn spots after a washable has been used.

• Brushables are a thick, paste-like formula that allows the paint remover to be applied in heavy layers so that it stays wet in order to strip multiple layers (up to 10 or more) in one application. Allows remover to cling to vertical or even overhead surfaces. Some paint removers are the "wash away" or "water wash" types. These terms simply indicate that the paint remover formula includes an emulsifier that permits the chemicals to mix with water and be rinsed away with a hose.
