I need to fix drywall ceiling and replace a couple of panels. I do have a few sheets taken off from another room (also from the ceiling), which means they're coated on one side, tape has been ripped off.
Most importantly, there are rips from screws which I could not find to unscrew, I simply pulled the panels down leaving the screws in the joists. Overall they're OK, but have some bulges and rips on the back.
Now having said all this; Would it be OK to re-use such drywall sheets? I could carefully fix those rips and bulges.
On the other hand, maybe durability of the panels now has suffered?
