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 guidance center suggests these tests: First is run your hand beyond the wood. If you can tone the texture of the grain, the Flooring Xtra Garage Carpet has a penetrating finish (usually a inclusion of a natural oil, such as linseed or tung oil, unclean with additives for drying) topped with 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, with 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 occurring and does not soak into the wood, the finish on the Flooring Xtra Garage Carpet 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 on a few drops of water and white a skin condition form beneath the droplets after not quite 10 to 15 minutes, the floors are hermetic with wax. To remove 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, say you will a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been hermetic with one of the older feat methods, it will flake off.
