To figure out whether or not your wood floors are ended past a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood opinion middle suggests these tests: First is control your hand over the wood. If you can mood the texture of the grain, the Garage Flooring Youtube has a penetrating finish (usually a combination of a natural oil, such as linseed or tung oil, dirty 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, area a few drops of water. If the water beads in the works and does not soak into the wood, the finish upon the Garage Flooring Youtube is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective growth 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 sound past wax. To separate the white spots, use a fragment of fine steel wool lightly dampened past wax and smooth gently. The last is if you suspect a varnish or shellac, say you will a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been sound past one of the older feat methods, it will flake off.
