To figure out whether or not your wood floors are finished later than a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood counsel center suggests these tests: First is rule your hand beyond the wood. If you can mood the texture of the grain, the Kitchen & Flooring Emporium has a penetrating finish (usually a fascination of a natural oil, such as linseed or tung oil, infected later than additives for drying) topped later than 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, later than polyurethane, which coats the floor in a protective layer.
The third is in an out-of-the-way area, area a few drops of water. If the water beads up and does not soak into the wood, the finish on the Kitchen & Flooring Emporium is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective addition has worn away. Fourth, if you sprinkle on a few drops of water and white bad skin form beneath the droplets after not quite 10 to 15 minutes, the floors are sound later than wax. To separate the white spots, use a fragment of fine steel wool lightly dampened later than wax and smear gently. The last is if you suspect a varnish or shellac, put up with a coin and graze the surface of the floor in an inconspicuous corner. If the floor has been sound later than one of the older ability methods, it will flake off.
