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 is a greener alternative to PVC (vinyl) and leather in both production and after-care. Naturally soft and flexible, polyurethane does not require the solvents used to soften PVC or leather in the manufacturing process. Leather production is an especially chemical-laden process involving heavy metals.
