I removed wallpaper and I found chalky plaser (joint compound) that the previous owner put on the textured walls to make them smooth for the wall paper.
The walls are not totally even, but could possible get away with looking a bit rusitc.
I dusted and vacuumed the walls and want to paint them (Behr premium paint with primer). Should I wipe the walls down with a damp sponge? I heard someone talk about sealing the walls in a previous post.
