ceiling drywall repair
I have repaired a hole in Wall that was about 2" across using a piece of drywall bigger than the hole and removing the "chalk" part to fill hole, leaving the paper intact bigger than the hole instead of using tape and it worked very well. Now I have a hole in Ceiling of bathroom I need to repair about 8" x 10". (replaced vent fan but had to be installed in slightly different spot, new one bigger and wouldn't fit under a pipe of some kind in attic space..I don't know what its purpose, runs from front of house to back of house, white pvc, about 3" in diameter) I was hoping to use this same method but I need to think of something to keep it in place while drying.
My 2 ideas are:
1)once dry wall mud and dry wall in place put a slat across it temporarily to hold in place. But will the weight of it eventually pull it down or sag?
2)Use the slat on the backside attached with drywall screws so it spans across the "inside" and use option 1 also until dry.
Does this sound like an o.k. way to repair?
What do you think this pipe is?
