I recently bought a "Bondit" branded gun for used with cans of expanding

foam.

I cleaned it out afterward with the appropriate aerosol can of cleaner

attached -- kept the trigger pressed and waited until it was coming

through clear -- but the second time I came to use it about a week later,

it's just not working.



Did you leave the cleaner in for an hour, then blast through, then leave

more cleaner for another hour and repeat 3-4 times? It needs to soak...




No, I followed the procedure in this Youtube video. It was all over in a minute and a half. He sounded so convincing:

What is the best way to get it working again or is it a binner? Can these

thing she disassembled and cleaned successfully or is it full of

ping****its that never fit back together again?



Shouldn't be. I took mine apart and rebuilt. There are places the foam gets

that do not get cleaned. You may need some Loctite thread seal (not thread

lock) for one or two of the screw joints. FAiling that, some PTFE tape might

suffice.



The bit that was a PITA on mine was the little green plastic ball that acted

as a non return valve where the can attached.

OK, thanks. I thought the gun would be a step up from straws but soaking/disassembling/thread seal sounds like exchanging one lot of problems for another.
