I'm not sure if it's Stucco or Plaster. I'm really new to this and have horrible wood paneling currently on the walls. When I removed one panel I discovered it was glued and nailed onto the original "stucco" walls. It's horrible underneath the wood paneling and I don't know what my options are to fix it? I read that I could add 1/4 rock sheet, any other idea's? How do I clean off the glue or do I sand it? Any health risk or issues I should be concerned with? This is my first home and I'm feeling overwhelmed. Thanks for any help!
