Polyurethane Drying Time Between Coats. If you apply too many oil based coatings on top of each. What is the proper procedure to apply multiple coats of polyurethane? From experience, it's very important to allow for correct drying times between each finishing step.
Sanding down the rough texture of the first coat of poly before applying the second coat.
This type of polyurethane is the because these urethanes are comprised of fewer solids, you'll need to apply several coats for. A longer time frame is acceptable. 2hrs if its same color, 4 if its a new color. That's a lot of time for dust to settle or bugs to land on the surface, marring the final product. Allow each coat to dry fully. Water based polyurethane dries faster. Polyurethane acts as a shield for your wood floors. I used minwax super fast drying polyurethane for floors in a satin finish.
