16 oz. Gaps and Cracks Insulating Spray Foam Sealant with Quick Stop Straw

Worked perfectly for our project!

Trigger snaps off easily with end of straw. Too weak. Cant fix.

I'm not a contractor so I bought Great Stuff in this DIY container to seal up cracks in my garage walls before insulating. As others have said, the nozzle is extremely difficult to use; the foam either barely comes out or it splatters all over the place. I was glad I was wearing a tyvek suit. Plus, as I know from past use, if you stop partway through a project and don't use the whole can right away, the nozzle seals up and the can is useless from then on. So I bit the bullet and went back to Home Depot and got the contractor-grade Pro Gun, and containers of sealant and cleaner. What a world of difference!!! The flow from the gun is finely adjustable and easy to set up for exactly the amount you want. Plus, you can leave the gun on the can and use it again and again, for up to a month. Unless you're on a very tight budget or are much better at dealing with frustration than I am, skip a few lattes and put the money toward buying the Pro gun; the job will be much easier and much more enjoyable.

The foam sealant works great and closing up the gaps from running copper pipes through the wall in my garage. I used this same brand but specifically for windows and door jambs recently and it is fairly easy to use. Can be a dirty job if you use too much foam. The foam continues to come out for about 2 seconds after you release the trigger. So it's best to release early before you want to end.

I sealed a couple of cracks and holes in my basement and everything worked great until I decided to stop and keep it for the next project. It just never stopped, it's in my garage now and it keeps coming out, I see a big blob of gooey stuff already and I am a bit worried that It will fill up my whole garage and I won't be able to open the door in the morning.

Take the straw off and you have a full blast substitute for a spray foam kit. 40 cans completely air sealed my attic and cost half of what the smallest froth pack costs.

For context Im a diy’er with no prior experience with spray foam. We moved into an older house which had gaps and holes internal to the house that were letting in pests and mice. So I turned to spray foam as the solution for larger gaps where caulking wouldn’t work. I started by buying 3 cans of this stuff. Let me tell you, it’s a nightmare to work with. Why? 1. The product comes out so quickly it’s difficult to control. You end up spraying way too much then have to spend a lot of time cutting extra. 2. Because of #1 is gets all over the place. Your hands, floors, clothes...really anything around. 3. The screw on spray tube is defective. With all three cans, the product began leaking out of the underneath of that screw on spray tube. 4. Some cans barely worked at all. One I got one spray out of before it jammed up and I threw it away. Overall this product is terrible. I gave up on GreatStuff and went and got a few cans of Loctite Tite Foam. Solved every problem above. Easier to control the spray, easier to clean up, and no leaks out of any of the cans. From my experience, vastly superior product. Having said that, in fairness, i have no results yet on which is more durable. A few tips if you’re like me and want to use this stuff: * use caulking wherever possible before turning to this * It expands, a lot. You can always add more so use lightly. * Spray foam is flammable. VERY. If I had known this up front I would have gone a different route all together. * Make sure you have plenty of disposable gloves. * Keep lots of paper towel around and a few wet rags to clean up. You’ll definitely want to wipe up overspray. * Get some acetone if you’re going to want the finished product to look nice. I didn’t care about that for where I put it so I didn’t bother. Good luck.

I used this to fill in the gaps around a wall-mount AC unit, so that I could tile around it, instead of using regular moulding. Worked out great.

Needed to eliminate vibration before I close up the wall for my home Music studio. Did what it was designed to do.

I try to seal around items in my attic and if you just slightly pull the trigger it flows out like a dam broke. It didn't stick so once this crazy amount of foam dried it just brushed away so not sealing any air leaks in the attic.
