A homeowner in my neighborhood has a house that is about 70 years old. In the 6 years she's lived there, she's had her plaster walls on the ground level painted 3 times by different contractors, but the paint begins to crack and peel after a year or two, mostly in the same places. She's not sure how many coats of paint are there, and suspects there may also be a layer of wallpaper. What are the options; considering possible lead-based paint in some of the older layers? She also asked about hanging drywall over it, but I've never heard of this - wouldn't you have to use anchors and would it hold up?
