We have a bathroom vent that is covered by a thin metal screen. It vents directly into the attic. I want to cover it with drywall. The ceiling is plaster.
I need a piece of backer wood so the drywall can attach to something. This is what I did.
I basically screwed the wood to the attic side of the plaster ceiling. It actually goes across the screen frame.
Should I have attached the wood to the wood beams instead. Note: a couple of small pieces of plaster ceiling fell off into the bathroom because of the screws.
I already screwed in the drywall piece from the bathroom.
