Mending Cracks and Bubbled Tape
- You can repair minor cracks simply by filling the voids with compound. But if the joint tape curls up from the drywall surface, first use a utility knife to remove all loose tape. Be careful you don’t remove the sound-fitting tape.
- cut a piece of joint tape to fit. Apply a bed of joint compound to the wall or ceiling, press the tape in place, and apply another coat of compound. Let dry, then add another layer of compound, then another if necessary. Feather each coat into the coat into the surrounding surface to help hide the seam. When the surface is smooth, finish the repair as instructed.
