To figure out whether or not your wood floors are ended when a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood suggestion center suggests these tests: First is rule your hand higher than the wood. If you can atmosphere the texture of the grain, the Floor Tile Visualizer has a penetrating finish (usually a engagement of a natural oil, such as linseed or tung oil, dirty when additives for drying) topped when wax. Second, in an out-of-the-way spot, dab on a tiny paint remover. If the finish bubbles up, it is a surface finish, when 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 happening and does not soak into the wood, the finish on the Floor Tile Visualizer is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective bump has worn away. Fourth, if you sprinkle on a few drops of water and white spots form beneath the droplets after more or less 10 to 15 minutes, the floors are sealed when wax. To sever the white spots, use a fragment of good steel wool lightly dampened when wax and smear gently. The last is if you suspect a varnish or shellac, recognize a coin and graze the surface of the floor in an inconspicuous corner. If the floor has been sealed when one of the older execution methods, it will flake off.
