How Do You Remove Polyurethane From Wood Without Sanding?
One way to remove polyurethane from wood without sanding is to use a chemical stripper. Apply the stripper to the wood, wait for it to dissolve the polyurethane, and then scrape off the residue. Be sure to follow the manufacturer’s instructions carefully, as chemical strippers can be caustic and require proper ventilation, protective clothing, and gloves. After stripping the polyurethane, clean the wood thoroughly with mineral spirits or a similar solvent and then refinish or stain as desired.
