Fill Gaps and Cracks with Great Stuff PRO Insulating Foam Sealant

Reader: If you've ever used the traditional spray foam cans you know they're hot garbage. This thing allows you to control the flow, and set such a small beard it's amazing.

I went crazy spraying all the cracks in a treehouse I built and it was a breeze. Super fast, easy cleanup, and seems as if the product lasts longer.

Definitely worth it.

John: The gun I got would not screw on the Great Stuff cans !!! The threads look ok (hard to see) but only went on a couple o threads, therefore it wouldn't spray the foam. Should have gone all the way on (4 threads ??) but no way !!!! USELESS !!!!!
The cleaner worked great to clean up the Great Stuff that came out around the threads of the gun.
WORTHLESS to me.
BUT, I called customer service (they were terrific) and they're sending me a new complete kit !!!!

Green Tree: As a handyman I often have a need to use a small amount of expanding foam to seal around a pipe or hole or opening. In the past I would keep load of cans of foam in my truck because if I waited more than a few days to reuse a can the can would be virtually unusable due to a blockage somewhere no matter how much I tried to clean it after use. Of course I could not determine if or when I would need foam again so I ended up throwing out large numbers of cans due to blockages. With this system I can dispense the correct amount and then close up the gun for use the next time. Never had a problem with any blockages and love the fact that I can control how much foam and at what rate I want to dispense the foam. In fact, I have only used 2 cans of foam in the last 6 months which shows me how much wastage I had before.

Now the cons, although they are no deal breakers. If you do happen to take a can off, and I did this twice, there is little you can do to stop the foam from just slowly, or fast depending on the can I guess, leaking out. From what I understand you are supposed to be able to take the can off and store it for use later but my limited experience with this system is that...

David B. RomeroDavid B. Romero: I though I would give this system a try, I have a new RV garage being built, I am aware of cost as this is a large garage over 35 feet deep 21 feat wide and the walls are 16Ft. tall and a loft in the back of the garage at 12ft. height. I needed to seal up around the windows the multiple exterior doors, wall penetrations for the electrical and water lines. I bought some of the low expansion to use around the doors and windows as to not distort the installation on the doors jams. That worked very well, i used the high expansion on areas I needed to fill and seal. in corners of the framing, penetrations around the A/C system in some of the areas. This is an awesome system, I think you get about 3 times the amount of chemical in the cans as you would get at the big box store for the of he shelf diy can. The best parts of this system is the ability to close the system and not waste the can, you can lock in shut or you can remove the can and reuse at a later date. Now with that said you need to buy a can of the cleaner, this stuff is great, you remove your can install this on the applicator run some chemical thru and it dissolves the foam chemical on contact, You can remove it when done...

delivery man: Happy with gun. however, one of the two great stuff cans leaked so badly that it was 95% waste--thought it was a gun issue, but after trying second can, gun was fine. As this is a Great Stuff product, guess I cant fault AWF, but was disappointed
