I have recently purchased a home (our first) and removed wallpaper from the bedroom walls. The wallpaper came off easily just by pulling. But I'm not sure what to do next. I want to paint the walls. Underneath the wallpaper there is a transparent blue coating that covers all the walls. Around closets and door its thicker in some places and changes the texture of the walls. I have tried to remove with warm soapy water but this is also taking off the texturing of the walls. What do I do?
