As mentioned in the title, we are scrapping a wall for new paint, and quickly found we have what seems to be this cardboard material looking stuff that peels off with the layer of paint just over it, and it seems to be hammered into the dry wall. What is this? Is it normal? Do we just sand it off the drywall? I can't imagine we paint over it.This is itAny info would be great. Thanks. via /r/DIY http://bit.ly/2ZYBS51
