How to Apply Polyurethane. Polyurethane is a type of synthetic varnish used for finishing and sealing wood. In interior applications such as finishing floors and wood furniture, polyurethane is harder and more resistant to abrasion than its naturally-derived counterparts.
Polyurethane for floors has 3 big benefits that make it unique and different from fast-dry poly. First, the dry time is 3 to 4 hours, 25% faster than traditional poly. Second, if you recoat within 12 hours, you don't have to sand between coats. Third, poly for floors is formulated with advanced anti-settling agents that keep the flattener (used in satin and semi-gloss) suspended all day, which results in less stirring time.
