How to Stain and Seal Hardwood Floors
Use a brush or roller to apply a coat of polyurethane finish.
Follow the grain of the wood when applying the polyurethane. Let the first coat dry for six to eight hours.
Polyurethane is durable and provides a glass-smooth finish that will protect your floor. Liquids spilled on a polyurethane finish bead up and can be easily wiped away.
