There is a crack in the drywall at the peak of the 15′ girl cave ceiling. It’s not actually a crack, it’s just the drywall tape separating from the ceiling:
My first attempt at repairing it involved a drywall patch kit I got at Home Depot. The patch kit contained thin metal plates with drywall tape stuck on the front and adhesive on the back. They might work well for a hole punched in the drywall, but when I pressed them against the ceiling, they stuck for about 30 minutes before cascading to the floor. Even as I was putting them up, I realized it wasn’t the solution I was looking for. I definitely need drywall tape to lay across the old tape and seal it back to the ceiling. What I need is something like this:
After work I’m heading to Home Depot to get the tape I need. Then it’ll be back up the ladder for me, to seal the crack with the new tape, cover it in mud [a.k.a. joint compound], sand it, and paint it.
