Well I am redoing the inside of my house and have all the cracks patched and have 1 coat of primer on the living room. Should 1 coat of primer be enough? I can still somewhat see the original color showing through a little in some areas. The reason I primered was because a friend of mine does a lot of drywall and he recommended it. He suggested it becuase the paint on the walls is old and smokey. I washed the walls down and primered with a white latex. In the dining room there are a few spots where the piant I am primering over is peeling... I cant get it to stop and I even if I do, I dont want the new paint ot flake off after a little while.. Any suggestions The primer laid nice everywhere except to walls where it is peeling some. Thanks!
