Siroflex PU foam drywall adhesive - an expanding foam with low
expansivity. I'm not sure if it would attack EPS (jablite) but I'm happy
to try a bit for you.

Watching a DG installer using foam the other day I was struck by how
well behaved the stuff was when applied with a gun rather than an
aerosol. I'm going to shell out for one, even if I only use it once in a
blue moon. It also means you don't have to throw away part used containers

Yes - and the foam I mentioned is exceptionally well behaved if you're
careful - it expands very little beyond the initial application. Sticky as
a sticky thing though which is good for the job and bad for your clothes!

The last foam aerosol I used spat and hiccupped before delivering an
uncontollable mass. Yes, I shook it to death before use too.

If you were in the habit of using 2 types of foam it might even be worth
buying 2 guns - you really can leave the gun attached and it doesn't gunk
up save for the outside of the nozzle.


I also observed this DG guy doing the silicone seal. Wipe with
forefinger, wipe forefinger down T shirt was his method. I imagine he
leaned said item of clothing against the wall when he got home.
He reckons if you apply the right amount, you don't need any implements,
let alone a Fugenboy.

He was also telling me how superglue has transformed the DG industry.
The accelerator spray sets it instantly, so you can fix one end of a
moulding before lining it up and spraying the rest. Essential if you're
working alone I would have thought
