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.
Use these high-build sealers to produce a very durable, chemical-resistant finish. Polyurethanes sealers are nearly twice as thick as an acrylic sealer and form a high-build protective film on the concrete surface that provides excellent resistance to abrasion and chemicals.
