To figure out whether or not your wood floors are over and done with behind a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood guidance middle suggests these tests: First is run your hand higher than the wood. If you can setting the texture of the grain, the Concrete Acid Stain Floor Designs has a penetrating finish (usually a assimilation of a natural oil, such as linseed or tung oil, poisoned behind additives for drying) topped behind 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, behind 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 taking place and does not soak into the wood, the finish upon the Concrete Acid Stain Floor Designs is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective deposit has worn away. Fourth, if you sprinkle upon a few drops of water and white a skin condition form beneath the droplets after just about 10 to 15 minutes, the floors are sound behind wax. To remove the white spots, use a piece of good steel wool lightly dampened behind wax and smooth gently. The last is if you suspect a varnish or shellac, put up with a coin and scrape the surface of the floor in an inconspicuous corner. If the floor has been sound behind one of the older talent methods, it will flake off.
