I moved into my house 4 years ago and had all the wall paper removed and the walls skim coated. My sons room is the only trouble room, the paint chipped and flaked in many places (old 70's and 80's like contact glue). I am in the process of repainting it myself, how should I prep the walls to eliminate future chipping in the future? Would a really good primer do the trick? Thanks in advance
