Your cart is empty.Great Stuff Gaps & Cracks Foam Sealant Kit reduces unwanted airflow and improves energy efficiency all around the home. Gaps & Cracks expands to fill openings, creating long-lasting, fire-rated seals around plumbing and electricity penetrations, duct work, sill plates, and rim joists from basements, to attics. Using our Great Stuff Foam Sealant Kit is easy. Pop the top off the can; screw it onto the gun; open the gun's valve; press the trigger and you are good to go! Still have foam left, leave the can attached to the gun and close the valve until the next use. Use the cleaner on the outside of the gun and clean the inside when you are going to store it for a longer time. After you use the cleaner, remember to remove the can and empty the cleaner from the gun.

Over the years I’ve probably bought & used 100 cans of expansion foam. Good stuff, hard to apply evenly, very inefficient. This pro gun is fantastic. One can sealed my entire rack room … and cleanup is perfect. I’m hooked.

I’ve been making animal decor out of great stuff foam for some time now, but just recently upgraded to the pro kit. This was game changing. Not only is the control of the foam much better.. but it’s FAR more efficient! With 1 can of the pro ($15) I can make what it would cost around $60-70 worth of the small cans.. this definitely will save you money on bigger projects!

Been using this in my basement remodel to seal small and large gaps. Having the large can and an easy to use spray gun makes the job so much easier!

Pretty good at feeding just the right amount of foam sealant but doesn’t work well in tight spaces . The rubber straws included for wiggling into tight spots are useless and just fall off . Gun needs to be held upright which was difficult toDo in the tight spots I was trying to fill

Consistant, accurate application.Able to use only what you need and not find things to foam up just to not waste the rest of the canClean application!Tiny bead, medium bead, humongous bead and all sizes in between!The only negative is you might start getting gurgles and spits when you work over your head and the can gets inverted. Not 100% sure that's the case. I stopped as soon as I got the first raspberry.Totally worth paying a little more for the cans.

This gun worked awesome until the next day when I went to use it and it was completely glued shut, uncleanable, and worthless. I followed the instructions and cleaned it well using the provided cleaner. Obviously not well enough. Cleaning this properly is going to challenge the average purchaser for sure. As a contractor it didn’t serve me any better.**UPDATE** The company reached out to me and stood behind their product by offering me a re-imbursement. They didn’t have to do that so that was entirely unexpected and GREATLY appreciated! My original rating of two stars is happily updated to 5 stars for them being proactive and making things right.

If your still using those basic spray cans with the straw you've got to move up to this system. Its some much more controllable, you can use the same can over and over, switch back and forth between different types of foam, and the cleaner works great as well.If your doing a large job or regular gap and air sealing this is a must have. Now that I have one, I can't understand why I didn't buy one years ago!

A product that Works as Advertised. Takes a little time but Trigger Control takes time. I can now draw a very small bread. I Learned of you make a mistake let the foam dry 10 -15 min where it hardens a bit. You can push the air out and compact it to fit. I prefer this to let it harden then saw away with razor knife as there are visable air holes. Anyways YMMV..
