To figure out whether or not your wood floors are over and done with gone a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood information middle suggests these tests: First is govern your hand more than the wood. If you can vibes the texture of the grain, the 16 X 40 House Floor Plans has a penetrating finish (usually a raptness of a natural oil, such as linseed or tung oil, contaminated gone additives for drying) topped gone 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, gone 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 up and does not soak into the wood, the finish upon the 16 X 40 House Floor Plans is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective growth has worn away. Fourth, if you sprinkle upon a few drops of water and white spots form beneath the droplets after nearly 10 to 15 minutes, the floors are sealed gone wax. To remove the white spots, use a fragment of fine steel wool lightly dampened gone wax and daub gently. The last is if you suspect a varnish or shellac, take a coin and scratch the surface of the floor in an inconspicuous corner. If the floor has been sealed gone one of the older completion methods, it will flake off.
