I can't find a firm answer on how to remedy this problem correctly.
Previous owners painted over the wallpaper paste/glue. What is the best way to handle this situation. Some say to sand the walls, some say to skim coat, some say to do both. Is there anything, like trying to steam through the paint down to the glue and scrape it off to get a smooth wall? Would like not only the easiest, but least costly and least messy possibility.
