I'm sure there's been a thread about this in the past, but I cannot seem to find it. The hallway of our 1792 home was replastered by the previous owners in the early 1970s. We removed a window in this hallway, which revealed very old, possible original, horsehair plaster beneath the current surface, which is about 1/4" thick (the current surface). The plaster is unpainted and almost stucco like (and its grey and depressing looking). I think the previous owners thought it would look "original", particularly in the places where they seem to have added swaths of darker grey (whcih almost look like water damage). I've tried sanding a small area, but then it occurred to me that there might be asbestos or lead in the plaster, and frankly, it seems like a better idea to resurface the entire hallway. I'm considering doing this myself...any experience with this? Advice? Would joint compound work? I'm up to the task, but my husband thinks it would be just fine to paint over it. I'd really prefer the walls to be smooth, and we're not really up to having a professional do it for us.
