To figure out whether or not your wood floors are done later than a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood counsel center suggests these tests: First is control your hand exceeding the wood. If you can setting the texture of the grain, the Rubber Flooring Utility Room has a penetrating finish (usually a interest of a natural oil, such as linseed or tung oil, dirty later than additives for drying) topped later than 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, later than 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 stirring and does not soak into the wood, the finish upon the Rubber Flooring Utility Room is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective accumulation has worn away. Fourth, if you sprinkle upon a few drops of water and white bad skin form beneath the droplets after practically 10 to 15 minutes, the floors are unquestionable later than wax. To remove the white spots, use a piece of fine steel wool lightly dampened later than wax and smear gently. The last is if you suspect a varnish or shellac, consent a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been unquestionable later than one of the older attainment methods, it will flake off.
