Correspondingly, can you apply a second coat of polyurethane without sanding?Q: What will happen to a wood floor if you do not sand between coats of polyurethane? A: Nothing, provided you apply each coat of finish within a reasonable amount of time. If you get dust nibs or brush marks in the finish, sanding will smooth them, and your next coat will look better if you work on a smooth surface.Additionally, how long should you wait between coats of wood stain? For highly absorbent woods, you can then apply a second coat, wait, and wipe away the excess again. Allow the pre-stain to dry for 30 minutes before applying stain, but no longer than 2 hours. Besides, what happens if you recoat polyurethane too soon? If you recoat too soon, this shrinkage of the bottom layer will cause tiny tiny ripples in the layer above while it’s still wet, making it not look as smooth as it would otherwise once it dries. If you don’t care, go ahead and recoat.How do you finish the final coat of polyurethane?Sand lightly with 240-grit sandpaper between coats, then let the last coat dry for at least 24 hours. This is standard practice with any wood finishing job, and is nothing out of the ordinary. That said, sanding bare wood beforehand to create a smooth foundation is key.
