To figure out whether or not your wood floors are the end past 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 govern your hand over the wood. If you can environment the texture of the grain, the Flooring Company Gainsborough has a penetrating finish (usually a fascination of a natural oil, such as linseed or tung oil, tainted 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 going on and does not soak into the wood, the finish upon the Flooring Company Gainsborough 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 upon a few drops of water and white bad skin form beneath the droplets after very nearly 10 to 15 minutes, the floors are unassailable past wax. To cut off the white spots, use a fragment of good steel wool lightly dampened past wax and rub gently. The last is if you suspect a varnish or shellac, believe a coin and scrape 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.
