What to Use to Seal Bathroom Walls
I have just removed wallpaper form a bathroom exposing rough plaster underneath. My plan is to wash residual paste off wall with Dirtex. Patch a few places with drywall compound. Let dry and sand wall with 120 and 180 grit sandpaper. My questions are 1) Is there anything else I need to do to prep walls and 2) should I seal the wall with bullseye 123 (shellac) or and I use Perma White as a primer/sealer and then put on a second coat?
