To figure out whether or not your wood floors are done when a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood counsel center suggests these tests: First is govern your hand over the wood. If you can air the texture of the grain, the How To Clean Hardwood Floors Bruce has a penetrating finish (usually a captivation of a natural oil, such as linseed or tung oil, polluted when additives for drying) topped when wax. Second, in an out-of-the-way spot, dab on a tiny paint remover. If the finish bubbles up, it is a surface finish, when 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 going on and does not soak into the wood, the finish on the How To Clean Hardwood Floors Bruce 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 approximately 10 to 15 minutes, the floors are sound when wax. To cut off the white spots, use a piece of good steel wool lightly dampened when wax and massage gently. The last is if you suspect a varnish or shellac, give a positive response a coin and cut the surface of the floor in an inconspicuous corner. If the floor has been sound when one of the older skill methods, it will flake off.
