To figure out whether or not your wood floors are done in the same way as a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood guidance center suggests these tests: First is direct your hand higher than the wood. If you can air the texture of the grain, the Floors For Living Spring has a penetrating finish (usually a inclusion of a natural oil, such as linseed or tung oil, poisoned in the same way as additives for drying) topped in the same way as 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, in the same way as 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 going on and does not soak into the wood, the finish on the Floors For Living Spring is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective layer has worn away. Fourth, if you sprinkle on a few drops of water and white spots form beneath the droplets after about 10 to 15 minutes, the floors are solid in the same way as wax. To cut off the white spots, use a fragment of fine steel wool lightly dampened in the same way as wax and massage gently. The last is if you suspect a varnish or shellac, agree to a coin and scrape the surface of the floor in an inconspicuous corner. If the floor has been solid in the same way as one of the older expertise methods, it will flake off.
