Great Stuff Pro Gun Repair

This video shows how to take apart your Great Stuff Pro Guns and repair them.

These are useful tools, but do tend to break down and I couldn't find any videos on Youtube showing how to take one appart and put it back together again, so I decided to make my own.

Dude. I watched your videos back in 2017. I was hatching a plan to build my own house and I would scour YouTube for people building houses. You were a part of my life. And now this year I have finally dried in my own house. And in the final stages of the build my gun jams. Lo and behold it’s none other than you who shows me how to fix my gun. There’s something so cosmic about that. You started me off and now you meet me at the finish line.

THANK YOU, THANK YOU!!! You saved me from either destroying my gun, or going to buy a new one. I didn't properly clean my gun the last time I put it away. The cleaner started to work, then everything jammed solid. Following your directions, the gun is working like new!!!!

You are the man! This is a must have video for people with these guns that hardly ever use them! Thank you VERY much!

Great review for cleaning. Anyone who uses one of these guns will need this information eventually.😊

I was 5 min away from jumping in my car and buying a new one. After seeing the video I saw this it really does need to be taken apart and cleaned. I disassembled mine like in the video and got it working. On mine the wand part was clogged. It was clogged for about 2 years in a closet.

Thank you so much the check valve and ball were pretty much one piece of spray foam, Took it apart and was going ok that's why, even though the cleaner was flowing fine. Thanks again, Sean.

Thanks man. Even though I cleaned the gun with the great stuff cleaner every time I used it, the valve still managed to get clogged. But thanks to your detailed valve disassembly instructions, I was able to clean out the ball and spring. A hard thick coating dried around the spring in the valve. Thanks a lot.

Dude I've tried to clean out the old guns so many times, and must have just bought 3-4 new ones after giving up in despair. This hack is huge! THANK YOU! It was the spring in the ball valve that must have been clogging mine up. I watched your video, ran to the garage and in 15 mins had mine working again. Really appreciate you!

[johnknight]

This is EXCELLENT! Thank you! Such great camera work clearly showing each part at each step and how you removed them. It seems no detail was left out. So many videos skip over "small" things and they're often just what I wanted to see. I'm totally confident I can unclog my gun with this video. 5 stars!

Spent good money on this gun and they put a plastic ball in the most vulnerable part. couldnt get mine out as the brass fitting was just crumbling so my gun is useless. glad you were able to fix yours and not loose money thanks for the video

I always store my guns well cleaned with no can attached. But my latest gun is clogged after I only used it twice. And I thought I had cleaned it well. This video is a big help. !

Blocked my second gun, (first was a Hilti, second is the Great Stuff gun). Thanks, for making this video--great help. Also, thanks to J. Martin for the tip on applying heat to the barrel threads. I'll try to clean my guns as soon as my cleaner order from Amazon comes in.

pro tip, try pipe wrenches if you have a stuck, partially stripped head. Pipe wrenches grabs tighter as you try to turn the stuck fastener. You can get mini ones.

This video is destined for glory as these guns skyrocket in price. Just payed @80$ in rural Wisconsin hardware store. 56$ on Amazon today. I remember paying maybe 35$ a few years back and feeling hurt. Thanks, my gun is better now.

[coatknight]

Great stuff!

Pun intended :)
Thank you for the great instructions.

[CharlesLaux]

Thanks! It sucks that you have to essentially shred the nozzle to get it off. But I finally did and my gun is flowing again.

[truenorthwoodshop]

Big thank you. Just what i need to know to clean my gun. Excellent video.

[gitarplayer]

I’ve switched to the disposable cans. The guns are just too much trouble and not with the hassle.
