How Do I Remove Polyurethane Coating?

Wood Floors

• The best tool for removing polyurethane from a wood floor is the orbital floor buffer, an electric tool that spins a large disc underneath its circular body. The disc contains a round, abrasive screen that removes the polyurethane. It is best to use a dull screen of either 120 or 150 grit. Corners and edges will have to be sanded with an electric sander.

Wooden Furniture

• Although chemical strippers containing methylene chloride (MC) can be used to strip polyurethane from wood furniture, this method is not very popular because of the possible carcinogenic nature of MC. The best solution is to mechanically remove the coating with an electric sander and rough sandpaper.

Non-wood Surfaces

• Polyurethane occasionally is put into use to preserve and protect ceramic tiles, flagstones, clay tiles or even metal. Although using a methylene chloride stripper may work in some of these instances, it is best to consult a professional stone setter or tile layer before attempting to remove the polyurethane coating.
