Default Re: Polyeurthane Sanding Question

Oil based polyurethanes can take something like four weeks to fully cure depending on the thickness of the coat and the ambient temperature. For the less durable water based types it might not take quite as long. Achieving a really smooth high gloss finish can be a long haul. When doing this it's best to apply thin coats and build the finish gradually. Much patience required.
