Painting Bathroom Drywall
Hello fellow gardenweb folks! I recently had my bathroom remodeled. We tiled the full size shower (no tub). The remaining walls were done with Hardiebacker (sp.?) board. This weekend, I went to replace the mirror with a new medicine cabinet and apparently some of the paint stuck to the back of the old mirror. When I took the mirror down, it ripped some of the paper off the drywall board. It looks like they just painted right over the drywall. Initially I thought this was ok, but I read some forums where people said they coated drywall with "mud" before painting (not necessarily in the bathroom).
Now, I'm trying to figure out if I need to repair the places where the paper is torn off, and how to repair it. Do I need to mud over all of the walls and then re-paint? Or can I just tape over the torn paper and paint over the tape?
