Should you sand between coats of drywall mud?
2 Answers. Yes, knock off any bumps between coats, but there’s no need to get it perfect. A screen sander on the end of a pole is the best tool for this job. And it goes without saying that you should minimize any bumps while the mud is still drying to avoid having to sand it later.
Can you only do 2 coats of drywall mud?
