Paint on Plaster Walls is Peeling Near Window
I bought a house built in 1940 this March that has plaster walls and though the bedroom wall looked okay then, a couple of months later the paint started the crack and peel ... some in sections of 12" or more. This condition appears to be isolated to the wall around a window. Now last winter was a tough one in Western NY and many people had trouble with ice dams, etc., so I'm thinking there may have been a problem with that. But there does not appear to be any active leaking anymore, and the wall does not seem damaged (it doesn't crumble to the touch or anything like that). So ... now I want to repaint the wall and my typical course of action would be to scrape, sand, fill, sand and paint. But I'm a novice in dealing with plaster so I've been doing some research on the internet. I've discovered that sanding is a bad idea since a house of that age may have lead in the original coat. I also found info that says that just scraping the affected area may not do the trick since it could just "shift" the peeling down the wall further. So, do I need to strip the entire wall? the entire room? I found some info on a soy-based paint stripper (Soy Gel) and was wondering if anyone knows if it works on plaster (I have a note in to them but haven't heard back yet). Assuming I do have to strip, then do I also need to seal or just prime? Is Kilz a suitable primer for plaster? I'm planning on useing a latex paint over the primer. Ok ... so that's the story. Can anyone offer any assistance with problem and how to tackle it? Thanks much!
