To figure out whether or not your wood floors are finished past a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood recommendation middle suggests these tests: First is rule your hand more than the wood. If you can vibes the texture of the grain, the Cement Floor Stain Remover has a penetrating finish (usually a assimilation of a natural oil, such as linseed or tung oil, mixed past additives for drying) topped past wax. Second, in an out-of-the-way spot, dab upon a tiny paint remover. If the finish bubbles up, it is a surface finish, past 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 up and does not soak into the wood, the finish upon the Cement Floor Stain Remover is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective enlargement has worn away. Fourth, if you sprinkle upon a few drops of water and white bad skin form beneath the droplets after just about 10 to 15 minutes, the floors are unassailable past wax. To separate the white spots, use a piece of good steel wool lightly dampened past wax and massage gently. The last is if you suspect a varnish or shellac, allow a coin and graze the surface of the floor in an inconspicuous corner. If the floor has been unassailable past one of the older feat methods, it will flake off.
