I have a home that was built around 1878 and I have a question about hanging drywall on the celing. I have gutted the downstairs living room down to the studs and celing joist. the room is 15'6" x 21'6 the celing joist run the 15'6" width. because I am doing this myself can I apply and extra 1" board to the joist and run the drywall the same way the joist run? I will be using 5/8" drywall. the reason I would like to do this is I am not an expericened drywall installer and have never used drywall butt boards before but will If I have to. any help will be appreciated.
