To figure out whether or not your wood floors are finished with a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood information center suggests these tests: First is direct your hand exceeding the wood. If you can tone the texture of the grain, the House Floor Plans For Flood Zones has a penetrating finish (usually a concentration of a natural oil, such as linseed or tung oil, tainted with additives for drying) topped with wax. Second, in an out-of-the-way spot, dab upon a little paint remover. If the finish bubbles up, it is a surface finish, with 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 upon the House Floor Plans For Flood Zones is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective lump has worn away. Fourth, if you sprinkle upon a few drops of water and white bad skin form beneath the droplets after about 10 to 15 minutes, the floors are hermetically sealed with wax. To separate the white spots, use a fragment of good steel wool lightly dampened with wax and daub gently. The last is if you suspect a varnish or shellac, take a coin and cut the surface of the floor in an inconspicuous corner. If the floor has been hermetically sealed with one of the older achievement methods, it will flake off.
