To figure out whether or not your wood floors are done past 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 control your hand higher than the wood. If you can setting the texture of the grain, the Kitchen Flooring Uneven Surface has a penetrating finish (usually a concentration of a natural oil, such as linseed or tung oil, mixed past additives for drying) topped past 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, past 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 Kitchen Flooring Uneven Surface is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective addition has worn away. Fourth, if you sprinkle upon a few drops of water and white spots form beneath the droplets after just about 10 to 15 minutes, the floors are hermetic past wax. To separate the white spots, use a fragment of fine steel wool lightly dampened past wax and rub gently. The last is if you suspect a varnish or shellac, take on a coin and scratch the surface of the floor in an inconspicuous corner. If the floor has been hermetic past one of the older execution methods, it will flake off.
