Cleaning Foam Gun


Well my helper forgot to close my Hilti foam gun. It's plugged. Any tips on how to clean this out?

I soaked it in cleaner for a couple of days and no luck. I'm reluctant to try and take it apart. But at $250 I'm not buying another one.

I might try laquer thinner, but I think that will destroy the plastic handle.

Any help will be appreciated.

Re: Cleaning Foam Gun


Xylene will def eat the foam, but the plastic will also take a hit, If you try Xylene, make it a surgical procedure, GMOD.

Re: Cleaning Foam Gun


I've taken mine apart before and (like Gene says) surgically cleaned all the parts and then put it back together.
That saved the plastic..................

Re: Cleaning Foam Gun


Kato
look in the bottom where the gun attaches to the can,look all the way down the hole,take a wd40 straw and poke it in there
there is a spring loaded ball there,make sure it's free,you may have to push firmly

hilti gun is the best

Re: Cleaning Foam Gun


For the price Hilti guns are overrated. I have never successfully cleaned a severely clogged plastic gun as they don't come apart as easy and the solvent softens the parts. Above the poster mentioned the ball with the spring if that doesn't move get a new all metal one at an insulation supply house. They run 50 to about 100 dollars

Re: Cleaning Foam Gun


Unless the foam is tactile and you can blast it out with a can of acetone foam cleaner you are pretty screwed.

Are we talking about the same gun here because they sell for 90 bucks (Canadian) from Hilti or come free with 2X 12 packs of foam. Only 40$ more then a GreatStuff gun.

Knowing the stuff Hilti makes I'd think there has to be a way to clean it. No doubt you'd probably have to completely disassemble it and use lacquer thinner, xylene or acetone. Maybe spray carb cleaner might also do it.

Re: Cleaning Foam Gun


Is your gun the DS-1? That's what I have, picked it up on ebay with 2 cans of foam for about 40.00. I haven't used it in over a year. They say to leave a can on with the valve closed so that's what I did. I was always wondering about long term storage with them.

I thought for long-term storage you should pop on the acetone can and purge it. I think if you leave a partial can on closed for too long it cures and your gun is toast.

Re: Cleaning Foam Gun


Yaaa!! It wasn't plugged. I had a can of cleaner on it that wouldn't spray.
I assumed it was plugged. What happened was the top of the cleaner can was actually stuck and broken in the foam gun.

Picked out the broken piece, put a new can of cleaner on it, and bingo!

I love it when something like that happens and I am saved buying a new gun.

Now ................ what can I foam

You are correct, always do that.

The broken cleaner thing is a new one for me.

The propellant in the cans gets out though rough handling or incorrect usage then you have a full can that won't spray

Re: Cleaning Foam Gun


We have a great stuff gun and the Dow rep who demoed it for us clogged it up. I had great success with their cleaning spray even on a clogged gun, mixed with some lengths of copper wire to fish the softened goo out as it loosened up. Definitely takes patience though. I know a few people who use acetone instead of the expensive cleaner cans when they need to break down a gun and it seems to work well enough.

Re: Cleaning Foam Gun


i never had much luck with the great stuff guns
the hilti guns can sit with a used can on it for quite some time
i think they use a teflon coating on them not sure

Re: Cleaning Foam Gun


Hmm, having the can break off is a new one on me too!

McBride, Hilti "gives" them away for free too.......







...with a purchase of 2 cases totaling over 400 bucks.
