To figure out whether or not your wood floors are curtains similar to a polyurethane, shellac, wax or varnish, or have a finish that has worn away and is no longer providing coverage, the American Hardwood assistance center suggests these tests: First is govern your hand on top of the wood. If you can setting the texture of the grain, the Garage Flooring Youtube has a penetrating finish (usually a fascination of a natural oil, such as linseed or tung oil, poisoned similar to additives for drying) topped similar to 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, similar to 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 occurring and does not soak into the wood, the finish on the Garage Flooring Youtube is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective buildup has worn away. Fourth, if you sprinkle on a few drops of water and white bad skin form beneath the droplets after about 10 to 15 minutes, the floors are hermetically sealed similar to wax. To surgically remove the white spots, use a fragment of good steel wool lightly dampened similar to wax and daub gently. The last is if you suspect a varnish or shellac, take a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been hermetically sealed similar to one of the older finishing methods, it will flake off.
