We bought our log house a few years ago and the bathroom has wallpaper on it. In trying to remove it i discovered that the builder/owner had glued the paper directly to the drywall without first appling any paint (perhaps this is normal?). What this means is that the glue has fused with the rough outer surface of the drywall. In removing the wallpaper the very outer surface of the drywall has torn away in many places. However, the inner chalk material is not exposed. We would like to paint the walls but first must do something about this problem as there is no longer a smooth surface. We were hoping to use something to prime the wall, then use a textured paint of some sort to help cover the walls. I've never done any of this before. Input, warnings, suggestions, ideas... all are welcome. Thanks in advance.
