Plastering over stucco
I have a car port that I want to convert into a bedroom. The car port has stucco walls on 3 sides and a stucco ceiling. All I think I need to do is add a fourth wall, a couple of windows and a door. My question is whether I need to rip out the stucco and replace it with drywall or if I can simply skim coat the walls with plaster. Can anyone help me with the pros and cons of each approach? Thanks.
