Insta Stik Expanding Foam Grab Adhesive 750ml
I have used this product and found the bond strength good, but only has a B2 fire rating as far as i'm aware. Most plaster boards has a 1 hr fire rating so you must be careful what you use to stick the boards up with. I have also used a Illbruck product which is in my opinion far superior and it also has a B1 fire rating which is a true fire rated product.
look for PU010 panel adhesive on the illbruck web site, this in my opinion is the correct product to use for this application.

Instastik Expanding Foam
To be honest i was a bit dubious about this to put up plasterboards, ive been used to dotting and dabbing. I bought 4 tins and went for it in my hall stairs and landing and what can i say its great, been plastered now 5 months and no sign of any movement or cracking on the joints on the boards. Also used it for filling a void where i wanted to hang a radiator, drilled the hole filled with this popped in a rawl plug and let it go off, screw in solid as a rock. Its a bit pricey but cant fault the stuff :-)

So far so good
Thought I'd try this as after trying to mount a curtain rail on plasterboard and normal plasterboard raw plugs wouldn't work due to the weight of the curtains.
Holes drilled, this stuff squirted in, raw plugs in then left to set for 20 minutes and the curtain rail and curtains put up.
Has held very well and none of the raw plugs moved at all.
Haven't used to attach plasterboard yet but will be doing in the next room given how well it's held.
Not cheap though which is the only downside.
Seems very solid so far and will be using again.

DO NOT BUY
This is an appalling product. The original Pink Grip foam is excellent for fixing plasterboard, but this stuff is awful. It continues to expand for a long time, pushing the board out of line. I had to rip one board off the wall and start again - it was still expanding the next day, as the foam still hadn't cured after 12 hours. Not fit for purpose, should be removed from the market immediately.
