Whoever (most likely the previous owner) did the mudding and taping of the drywall in the stairwell of my home obviously wasn’t going for perfection…or even good enough for that matter. Lots of sanding marks, bumps, bubbles, etc. all painted right over. So, what’s the best method to fix this. Should I try to sand everything smooth? Or would it be better to apply a light skim coat over the entire surface of the walls? If I go this route, will there be any problems (adhesion) caused by the fact that it’s already got a coat of paint on it? I want this to look right, so I’m not neccessarily looking for the easiest fix, but the best. Thanks!
