I am putting in a coffered ceiling in my dining room as part of a major remodel. The old ceiling is already down and once I install the new recessed lighting frame-in kits, I will be ready to reinstall the new ceiling.
The question is this.
Since I need to install a new ceiling, should I just put up some 5/8" sheetrock or perhaps 1/2" plywood as the base for the coffered ceiling?
Thanks.
