To figure out whether or not your wood floors are the end later than 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 exceeding the wood. If you can vibes the texture of the grain, the How To Clean Hardwood Floors With Mineral Spirits has a penetrating finish (usually a amalgamation of a natural oil, such as linseed or tung oil, poisoned later than additives for drying) topped later than 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, later than 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 in the works and does not soak into the wood, the finish upon the How To Clean Hardwood Floors With Mineral Spirits is intact. If the water is absorbed into the floor or leaves a dark spot, the wood is unfinished or the protective mass has worn away. Fourth, if you sprinkle upon a few drops of water and white spots form beneath the droplets after roughly 10 to 15 minutes, the floors are unquestionable later than wax. To sever the white spots, use a fragment of good steel wool lightly dampened later than wax and daub gently. The last is if you suspect a varnish or shellac, resign yourself to a coin and scuff the surface of the floor in an inconspicuous corner. If the floor has been unquestionable later than one of the older capability methods, it will flake off.
