I am going to overboarding a my 3m/2.33m Kitchen Ceiling with 12.5mm Plasterboard.
I’ll batten around the walls and across the joists at 90′ using 300mm centres, and I will have help to get a whole 8/4ft Board upto the ceiling, so only expect 3 joints in the ceiling.
Will I need to noggin between the battens on the plasterboard, or is 300mm centre short enough to stop 12.5mm flexing with a good skim?
Happy to load pictures or drawings if needed. Thanks for any ideas
