Goodmorning.... Last winter I had leaks around a skylight to the point where some of the texture and joint tape/compound got wet enough to separate from the paper face of the drywall board. I fixed the leaks and over the months the ceiling has dried out. Now I would like to repair the finish........ when I scrape/flake off the bubbled areas (biggest is appx. 1'X 3')the paper of the wallboard seems to be ok. Can I put new tape and joint compound where needed and texture as required to complete the repair? Or do I need to cut out any wall board that had been wet? The ceiling does not look like it is moldy.
