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 information middle suggests these tests: First is manage your hand on top of the wood. If you can tone the texture of the grain, the Reading Floor Lamp Target has a penetrating finish (usually a combination 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 tiny 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, place a few drops of water. If the water beads occurring and does not soak into the wood, the finish upon the Reading Floor Lamp Target 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 a skin condition form beneath the droplets after nearly 10 to 15 minutes, the floors are unassailable past wax. To remove the white spots, use a piece of fine steel wool lightly dampened past wax and rub gently. The last is if you suspect a varnish or shellac, bow to a coin and scratch the surface of the floor in an inconspicuous corner. If the floor has been unassailable past one of the older completion methods, it will flake off.
