decorators caulk

samohtom · 10 Dec 2010

Hi. I'm in the process of putting up new plasterboard on my ceiling studwork. The ceiling itself is concrete block and beam. The concrete blocks are the cheap hollow ones (pebble like/rice crispie like appearance), and there are a lot of gaps up to about 10mm wide in places round the edges of these. I was thinking it would be a good idea to fill these gaps before I put the insulation and boards up, and was wondering if decorators caulk would be suitable? I've looked at the COSHH and it says it's non flammable so from that point of view I guess it should be ok?

Thanks

Tom

I think expanding foam will be a better choice.
