When I removed the wallpaper in my powder room, I found it had been applied directly to the drywall. It came off easily but unfortuately it took the top paper layers off the drywall. I now have fuzzy walls and ridges where the joint compound meets the dry wall. I was planning to get as much of the torn paper and fuzz off, skim coat over the current compound to extend it over the ridges, then sand and hope I get a smooth wall. Then I'll prime and hopefully be able to paint. Does this sound right? I am really concerned I won't be able to get a smooth wall. Any other advice? Thanks!
