this looks like a great product!!, on site i went and had a talk to the guys building the steam room and while talking to them i noticed that they where fitting the boards to the walls and together with a foam like this , it could be the same stuff but its a lot easier than dot and dab!!
have a look!!

The walls have got to be very flat with that amount of foam.............

The guy knows his plastering starting in the middle of a wall

As Whitebeam says, ok on a flat wall, I wonder what load it will take, also not sure about using it on stud walls, surely screws would be cheaper, but I do like the concept.

we are all thinking OK on a flat wall but surly with the foam expanding ,it should overcome the undulations of an uneven wall!!

But could the expansion push the boards slightly out

good point beam!! i dont know, i need to try the stuff first!!

I'll stick to the plasterboard adhesive if need be

It's good stuff but tends to push the board out on smaller cuts. Only used it on three jobs, had a dot n dab job last week and I went back to using bagged dri-wall adhesive, messyer but feels a lot more solid to me;-)

dry wall addy for me gooner as you can put dabs where you know you'll have fixtures and fittings screwed in.

Not convinced by that stuff at all - for pretty much the same reasons as already mentioned

Once the foam starts expanding....

seen this on the shelves in the builders marchants but had the same thoughts as the others!!

There are english versions of this method..

C,mon get real.. unless perfectly flat then it will not work.

It works and its great......just not for tiling onto. I have used it quite a lot on window reveals and raising cills etc. Worth having a can in the van.

One thing it is great for is when you have a known void on dot and dab boards that have been fitted in the conventional manner. You can punch small holes in teh boards and inject the foam to fill it. I use this method ofr fitting kitchen wall units so the boards dont snap when you do the fixings up.

Replaced a damaged bit of wall this week that was dot n dab. So I cut out the damaged part and as you said in your post used the foam to strengthen the part of the board. Still used bagged stuff for the half board I replaced tho.
