To figure out whether or not your wood floors are done subsequent 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 manage your hand over the wood. If you can setting the texture of the grain, the Water Based Concrete Floor Stain has a penetrating finish (usually a amalgamation of a natural oil, such as linseed or tung oil, dirty subsequent to additives for drying) topped subsequent 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, subsequent 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 going on and does not soak into the wood, the finish on the Water Based Concrete Floor Stain is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective layer has worn away. Fourth, if you sprinkle on a few drops of water and white spots form beneath the droplets after not quite 10 to 15 minutes, the floors are strong subsequent to wax. To separate the white spots, use a fragment of good steel wool lightly dampened subsequent to wax and rub gently. The last is if you suspect a varnish or shellac, believe a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been strong subsequent to one of the older achievement methods, it will flake off.
