To figure out whether or not your wood floors are the end later a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood information center suggests these tests: First is run your hand on top of the wood. If you can character the texture of the grain, the House Floor Plan Grid has a penetrating finish (usually a inclusion of a natural oil, such as linseed or tung oil, infected later additives for drying) topped later 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, later 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 on the House Floor Plan Grid is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective increase has worn away. Fourth, if you sprinkle on a few drops of water and white bad skin form beneath the droplets after practically 10 to 15 minutes, the floors are unassailable later wax. To separate the white spots, use a fragment of good steel wool lightly dampened later wax and daub gently. The last is if you suspect a varnish or shellac, take a coin and cut the surface of the floor in an inconspicuous corner. If the floor has been unassailable later one of the older skill methods, it will flake off.
