if the joists are 24" oc, why would you put screws 12" oc? half of them are gonna miss the joists? you don't wanna do thatAdding 1/2'' ply over 3/4'' ply. Floor joist 24''oc. About 16 sheets.
I know I could screw it off, but thought nailing would be faster.
Screw/nail pattern. 12''oc ?
Maybe I'm just an idiot, but I'd glue and screw, with 3" into the joists, and 1 1/4" in the field for extra holding power, and to help eliminate squeaks. I dread call backs for squeaks. Far easier to overdo it at the beginning, in my opinion.if the joists are 24" oc, why would you put screws 12" oc? half of them are gonna miss the joists? you don't wanna do that
Good point. Personally, I would never nail a sub-floor.I think if you have screws in the field not into the framing what's gonna keep them from popping out when the floor moves? you don't want nail/screw pops especially if there's gonna be tile on top
