I just bought a house. The previous owners pulled their curtain rods down and damaged the walls. What happened to me is much like what happened in this thread.
I went to pull off a loose bit of paint, and now have a huge spot where the paint just peels off. Underneath the paint is what I think is drywall - not paper. It's sort of chalky. You'd think that paint would soak into it, but it didn't.
If I understand the composition of drywall, there should be a layer of paper over that, so I think it's peeling off too.
I stopped peeling to see what I should do next. Thanks to the other thread, I think I need mud and orange peel spray. I guess I just want to make sure I don't need to worry about the fact that there's no paper on the drywall. Or that I think I could keep peeling until the whole room was white.
We are going to go over the room with primer anyway, so at least that's not going to change our plans dramatically.
