I need to refinish the drywall ceiling in my bathroom after patching a small area where a chase was. It has a truss roof system above it. 24" on center with 1/2" drywall. I need to know the best way to do this. My plan was to nail new drywall over the existing drywall and start from scratch. But after reading about CPS I think my method might fail. Can I install a lid over the old? Or do I need to take the rock off everything in order to support the lid edges with the wall rock?
Thanks
