plasterboard on OSB ... working method?

[mr_s_d]

I'm going to put drywall on an OSB board in my kitchen renovation. I have 90 cm OSB and 90 cm drywall. Should the joint on the drywall be offset so that the joints between the boards don't line up?...but in that case, the drywall won't be attached directly to studs everywhere, only to the OSB board...but maybe that's okay. What should the screw spacing be?

Everything you attach to the wall should still be fixed beyond the drywall and into the OSB, so for that reason it doesn't matter. But stagger the joints to reduce the risk of cracking, I suppose...

CC 150mm on the drywall.

If you have 900 mm OSB boards, the studs are set at c/c 450, and you mention that you also have 900 boards for the drywall. Offset the drywall 450 mm from the joints on the OSB so you have a stud to screw into. Drywall sheets should never be general jointed due to the risk of future cracking. Regarding distance, on the edges, screw approximately 200 mm between screws, and in the middle, 300 mm. For screws along the paper-clad edge, place them about 10 mm from the edge, and for the non-paper-clad edge, place the screws about 15 mm from the edge.

No general errors as I said.

Attach the OSB with a few screws and then screw on the gypsum with longer screws through the OSB into the studs.
