Without some kind of finish to protect it from the elements, wood can become as dry and lifeless as day-old toast. It's a kind of super-tough varnish formulated so that its microscopic chains of resin molecules will bond tightly with one another as it dries. Most exterior polys can be used indoors, but interior polys should never be used outdoors; they lack the additives that protect exterior finishes from UV rays. To keep a partially filled can of oil-based poly from skinning over, cover the finish with this amount of mineral spirits. Use natural bristle for oil-based finishes and synthetic filament (polyester, nylon, or a blend of the two) for water-based and water-based oil-modified finishes. Your brush will be easier to clean, and will go longer between cleanings, if its bristles are dipped first in mineral spirits, if you're using an oil-based poly, or in water, if the finish is water-based.
Working from a separate container prevents the dust and other particles picked up by the brush from contaminating the finish in the can.
After dipping about one-third of the brush into the finish, gently slap it against the inside of the container. Wipe the wood with a damp cloth to raise the fibers; after the surface dries, knock them back with 220-grit sandpaper. Coating wood cabinetry, furniture, or trim with a clear finish, whether you stain it or not, gives it richness and depth while protecting it from knocks, scrapes, and the weather.
The result is a finish that's much more resistant to water, solvents, abrasion, and impacts than traditional varnishes.
Appears cloudy in the can but dries to a tough, amber-colour film, like an oil-based finish. Just remember that the glossier the finish, the more it will show any underlying imperfections and any future wear and tear.
Made with a special blend of oils and resins that allows it to flex as the wood surface expands and contracts.
Use a cloth dampened with mineral spirits on oil-based finishes; use a water-dampened cloth on water-based finishes.
Then you can be sure you're using just the right finish to bring out the beauty of wood around your house. Usually lower in VOCs than oil-based finishes but still requires good ventilation during application.
