Furthermore, how do you finish the final coat of polyurethane?
Polyurethane Finish Tip#1: Start With aThickCoating Sand lightly with 240-grit sandpaperbetweencoats, then let the last coat dry for at least24hours. This is standard practice with any woodfinishingjob, and is nothing out of theordinary.
Secondly, what happens if you don't sand between coats of polyurethane? A:Nothing,provided you apply each coat of finish withinareasonable amount of time. If you get dust nibs orbrushmarks in the finish, sanding will smooth them, and yournextcoat will look better if you work on asmoothsurface.
Simply so, do you have to put polyurethane over stain?
