Surface Prep Before Cornerbead?
Posted: Wed Jul 29, 2009 10:33 pm
I guess the wallboard would be considered a "non porous" surface, so do I need to sand it lightly before mudding in the cornerbead so it will really stick?
I don't know for positive, but I don't think you should sand wall board. I never have and have never had a problem with it.
