Is there anyone who doesn’t have a disaster story involving an expanding foam gun?

The other day, I was looking at mine wondering whether the valve on the top of the can was resealable or not. I.e. can you swap your can before it’s empty, or not.

You can imagine the rest.
 
I gave up on foam guns and now i just buy hand held and use it in one go.
Lots of waste on occasions, but what can you do.
I spent too much time battling with those foam guns.
Possibly they are ok for people who use them every day, but for anyone else it must be hand held.
 
I gave up on foam guns years ago because of problems with clogging up! Anyway I needed some foam a few weeks ago and they only had gun cartridges so I bought a gun and away I went. For the first few times everything was dandy so I thought I would carry on using the gun. Then it got blocked so I thought I would remove the cartridge and clean it. Well that was a mistake! f00kin foam everywhere.
 
Had the same, caught once. Happened one other time, but I was already undoing it outside into a rubble bag just in case!

Worth the risk I find, the gun is a much better tool that the disposables.

And cheap guns seem just as good/bad as the expensive ones!

I have no idea if this is dangerous or not so you should find out from experts first!

On the disposable cans I use acetone to clean the tubes and top out afterwards, you will be amazed at how quick and easy acetone dissolves the gunge, leaves it looking as clean as new. I have reused a half full cans a couple of months later with no problems, even had 3 or 4 goes out of the same can. And the acetone I use is just stuff the wife buys for her nails or something

You could get a foam gun cleaner can and use that to clean a disposable foam can. It is just acetone with a propellant I believe.
 
doesn't work if the foam has set inside the gun.
 
I'd never go back to disposable now I've got a gun. The tip of mine blocks when it dries but just scrape off with a knife and you're away. It's never blocked the tube itself. So much more controllable, too.

I see you’re using non-flame-retardant foam in that vid.
Imagine you now needed pink flame-retardant foam, or maybe sticky foam.
This is the scenario I found myself in....
