I've had a Rawlplug foam gun for a couple of months and only got
around to using it properly today (I'd ****ed around with one
previously, but not for long).
By 'eck, it will pay for itself in the long term - I will have a need
for many cans of foam over the next year or two and the gun makes the
bead of foam so much more controllable and as big/small as you like -
also puts it exactly where you want it.

How easy is it to clean after each use?

and do the gun grade cans of foam "knacker" after being part used just
like the handheld versions?

Ensure you store it can-up (i.e. how you would hold it to use) and ALWAYS
with a can attached containing foam, not empty.

Screw the shut off valve tightly closed when you're done and it'll last
almost indefinately.

The procedure I adopt is to leave the can on the gun. Then when reusing,
slice a sharp knife over the end of the nozzel to clear any stuck foam,
and then it usually works fine.


If you dismount the can from the gun and flush it with cleaner, then you
will probably find the can will de-pressurise the same way as the
disposable cans do. (not to mention the wasted foam in the gun etc)

how long will it stay "good" for like that - stored "can up" as per

I have left one for weeks certainly - possibly a couple of months.

I give it a squirt every few weeks to make sure there is some fresh stuff in the gun. If you leave a can for many months it can lose pressure and then the stuff gets air/moisture and it cures.
My last gun died that way. This is especially liable to happen if the can is nearly run out.
Apparently if that does happen you can take the gun to pieces and mechanically remove the foam. I with I had tried that, but I chucked it in the skip and got a new one!
Also I note the comment about storing it can upwards. I'll reposition my gun when I get home !

I had a can of foam cleaner which I squirted through afterwards - that
was easily done. I only used a fraction of the cleaning can, so it
makes the cost of cleaning not as bad as I expected, but I still sort
of resent paying €6 per tin for nothing but acetone.

Both points noted, ta.

So presumably with that level of control you could add buoyancy to a
canoe with perfect accuracy?

I wouldn't expect so, as canoes are a total law unto themselves.

Like many others I've found it to be very versatile indeed, and was
recently surprised how good it is for fitting skirting boards.
As for canoes it would cost nothing to do a few experiments checking
porosity and bouyancy ets before trying it out. It does seem to degrade
with exposure to UV but that shouldn't be an issue inside a hull, nor
should the final appearance although something like a temporary bulkhead
with expansion hole could be improvised to shape it according to one's
needs.

Sounds tongue in cheek but watch out, aerosol foam is not closed cell so
will absorb water, dramatically affecting its boyancy ;-).

Boyancy foam needs to be 2 part closed cell which, as you pointed out,
is er, less controllable.

Would it be possible to keep huge canisters of this stuff on board ships, and set it off like an air bag when a collision occurs, like the Costa Concordia ?

Or to bring in a rescue boat similarly equipped.

Nah, no strength in the bubbles/cells until they're set.

I think you will find the reference to a "canoe" is a reference to
