Can I drywall over this ceiling?
I currently have a kitchen ceiling in an old house with square tiles installed with furring strips behind it. The furring strips are nailed into a plaster layer that is in bad shape and is not salvageable(thus the square tiles being installed by the previous owner). Behind the plaster is concrete. I am thinking that I can go over the furring strips with drywall, but I am unsure how well the furring strips are in the concrete behind the deteriorating plaster. How sturdy do they need to be? Should I go ahead with this plan and reinforce the furring strips into the concerete or consider any other options??
