Putting drywall on reverted ceiling

[Lärasigattbygga]

Hello,
I have torn down a huntonit ceiling in a bedroom and have a plastered ceiling with a reed mat left. Underneath there are boards. The house is from 1936. The plaster is very porous and falls down quite easily, but I would like to avoid dismantling it if possible, because it would be so dusty and a lot to take to the tip. My question is if I can put gypsum directly on the plaster and screw it into the boards above, or if I need to add battens and frame it up to have some air space in between? Grateful for your help.
Best regards, Ulrika

My question is if I can put drywall directly on the plaster and screw it into the boards above, or if I need to install laths and build it up to have some air in between? Grateful for your help.
Kind regards, Ulrika

Did you get any answer to your question? I want to do the same and am interested to know.
Grateful for a response. Best regards,

it is possible but you need to use longer wood screws for gypsum, try with 55mm, and there is some space between the boards.

We got help from craftsmen to screw up a new ceiling in the basement of the previous house where reeds and plaster started to come loose. There, they screwed up tongue and groove boards across the entire ceiling, and it went just fine. Sheets probably work just as well as long as it's still reasonably flat.
