To figure out whether or not your wood floors are ended behind a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood guidance middle suggests these tests: First is govern your hand on top of the wood. If you can quality the texture of the grain, the Can You Stain Concrete Floor Leveler has a penetrating finish (usually a fascination of a natural oil, such as linseed or tung oil, mixed behind additives for drying) topped behind wax. Second, in an out-of-the-way spot, dab on a little paint remover. If the finish bubbles up, it is a surface finish, behind polyurethane, which coats the floor in a protective layer.
The third is in an out-of-the-way area, place a few drops of water. If the water beads taking place and does not soak into the wood, the finish on the Can You Stain Concrete Floor Leveler is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective deposit has worn away. Fourth, if you sprinkle on a few drops of water and white spots form beneath the droplets after approximately 10 to 15 minutes, the floors are solid behind wax. To sever the white spots, use a piece of fine steel wool lightly dampened behind wax and rub gently. The last is if you suspect a varnish or shellac, tolerate a coin and cut the surface of the floor in an inconspicuous corner. If the floor has been solid behind one of the older endowment methods, it will flake off.
