I am remodeling GFs 50's era bathroom.The walls are drywall with about
1/4-3/8" (varies) of plaster on top. I removed some tile and need to put up new wallboard on lower portions of the wall. She wants to paint the walls. What is the best way of getting a smooth surface. I had thought that I would just shim 5/8" greenboard but now I'm wondering about the joints. Better to just remove the drywall/plaster from the entire wall? Drywall and more plaster? Thanks.MH
