Catherdral Ceiling - Drywall Tape Problem
We have a house that is six years old with cathedral ceilings in the family room. There is a flat area at the peek of the celing that is approximately 5' wide. The drywall tape on the joints where the sloped ceiling meets the top has come loose. I pulled down both lengths and found a crack underneath about a quarter inch wide along the entire length. The tape I pulled down had very little mud over it.
1. Is replacing the regular tape with Strait-Flex Medium a good option or would another type of tape be better?
2. What kind of mud should I use under and over the tape? I think I read somewhere that plaster might be best?
3. Any other tips so that the tape doesn't come loose again?
