All types of wood require at least two coats of oil-based polyurethane. The first coat works as a primer and sealer; the second serves as a finish coat. With water-based polyurethane, a third coat is recommended, because the finish wears away fairly quickly.
Two coats of finish are suggested for most interior projects. When sealing floors, you should apply three coats. However, do not apply more than two coats in one day. 220 grit sandpaper should be used between coats to remove any air bubbles, but avoid using steel wool.

Around two hours is common for a first coat, though wipe-on finishes (which are easy to apply over smaller surfaces, such as wood furniture) can take a little longer. After this initial drying stage, a second coat can be applied if necessary.
