Default expanding foam

Its a little different - sets faster and expands less after initial
application. So you can push the board into place, and it won't expand
it away again. I have used the ordinary stuff for fixing plasterboard.
Its fine as long as you make sure its tacked or otherwise held in place
until the foam sets.


Since my ordinary foam can is almost empty, I might just buy the fast
setting stuff to avoid the hassle. I don't want my wall sloping!

In theory you can remove a can and it should seal - however in reality
they do it about as well as the normal "disposable" cans. i.e. leave it
a day and the used can will probably have depressurzied. If swapping
between a couple of cans in the space of a few hours, however you would
probably be ok.


But if you swapped can A for can B and then fitted can A again,
wouldn't that still leave you with an open can (B), which would
quickly become useless? Or were you thinking more along the lines of
swap A for B, use B completely, and then refit A all in the space of
the same afternoon?

Thanks.
