Attach drywall to chimney???

[JimmyB]

Hello!
???
The plasterer wants me to attach a drywall (Danogips) to the chimney breast that passes vertically through the bathroom. He wants me to glue it with something I think is called S-48 glue.
However, for gluing the floor drywall, I bought a tube recommended by Danogips for gluing their drywall to chipboard.
I tried it but it stuck well to the drywall but not at all to the chimney breast!!
Any tips? Nail it to the chimney breast as well?
Thanks!
Jimmy

Plaster and a couple of small nails and it stays in place.

try pappnubb or some shorter steel nails.

One more thing, should the plaster that is already on the chimney breast be sanded off completely to get to the bare cement, or is it enough to just remove the loose parts to achieve an even surface? :

Knock away what's bomt. Then splash on with bruk and slaffsa the board in place. Nail it with 75 nails in the joints. Bend the nail before you drive it in as well...
