To figure out whether or not your wood floors are done afterward a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood suggestion middle suggests these tests: First is run your hand higher than the wood. If you can environment the texture of the grain, the Copper Floor Reading Lamp has a penetrating finish (usually a inclusion of a natural oil, such as linseed or tung oil, tainted afterward additives for drying) topped afterward wax. Second, in an out-of-the-way spot, dab on a little paint remover. If the finish bubbles up, it is a surface finish, afterward 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 on the Copper Floor Reading Lamp is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective bump has worn away. Fourth, if you sprinkle on a few drops of water and white bad skin form beneath the droplets after about 10 to 15 minutes, the floors are sound afterward wax. To separate the white spots, use a piece of fine steel wool lightly dampened afterward wax and rub gently. The last is if you suspect a varnish or shellac, tolerate a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been sound afterward one of the older finishing methods, it will flake off.
