Product Overview

  • Air-sealing and insulating saves up to 20% on home energy costs
  • A quick, simple way to create an airtight, water-resistant seal
  • 16 oz. Gaps and Cracks Insulating Foam Sealant
GREAT STUFF Gaps and Cracks is a polyurethane-based insulating foam sealant that fills, air-seals and insulates small gaps (up to 1 in.) inside or out. But you probably guessed as much from the name. What you might not have guessed is how easy it is to use, thanks to the straw applicator, or how it expands to take the shape of cracks and voids to form a durable, airtight and water-resistant bond that eliminates unwanted airflow and helps reduce condensation.

Questions & Answers

can this product be used to seal around an electric dryer vent?

I am concerned about the temperature and possible flamability
Asked by: bf24
I used it about 14 years ago to seal up around my gas dryer vent. Just last month while remodeling the basement, I had to chip the old Great Stuff from around the vent in order to re-align the elbow for the new drier location. It wasn't super hard to remove the foam, but it took some work and I was impressed with how well it had held up over the years. Once the dryer and the new vent piping was in place, I used two cans to seal up around it and lock the elbow and joint into position.

Is this the correct product to fill in stucco cracks?

Asked by: Cajy
No. Use a good quality stucco patch made by Rapid Set, available at Home Depot. I've done it myself. You can watch a good demo of this on You Tube.

Is the foam yellow or white? I'm looking to use it for a craft project :)

Asked by: MikesWife
Try DAP expanding if you are looking for white BUT it doesn't add up to quality of Great Stuff.

Can I use expanding foam to fill gaps in brick work under bog stone on a chimney?

Will the heat from the chimney cause a fire?
Asked by: Lucy
You need something like "Refractory Ceramic Fiber Moldable Sealer". Try Googling that term and see if you can find it locally; otherwise, you might be able to purchase on the Internet.

16 oz. Gaps and Cracks Insulating Foam Sealant is rated 3.3 out of 5 by 58.
Rated 5 out of 5 by from Just clean out the tube for multiple use I've been working over many months on various house issues and have used this same can of sealant multiple times - from large voids around 4" drains to small ones around electrical runs. Wear eye protection if you plan to clean out the tube, and use very low (5 psi) pressure and blow out the tube, a long, wooden Q-tip, and some denatured alcohol. Haven't had any problem with clogging. Also clean out the nipple on the can. These cans are not that expensive anyway but I'm scrappy. And on larger jobs where I've blown through multiple cans, they have all worked well. It's easy to overfill voids especially when you can't see the other side so have patience with the expansion. And large voids fill fine - just pause for a few seconds and be light on the touch, and it will all stick together. Wear disposable gloves and have some paper towels with you just in case.

Rated 2 out of 5 by from Make it a big job, because you can't use it a second time Once you start using this stuff, it just keeps on coming, so don't plan on taking a break for lunch or finishing the job tomorrow using the same can. Also don't even think about getting it on your hands, clothes, finish work or anything you don't want to wear it forever. Clean up is difficult to impossible.

Rated 4 out of 5 by from Could be a lot better perhaps ? I would only recommend this product as there are no better alternatives that I'm aware of. So many times I come across situations where I need a small amount and then have to throw the rest of the can out as it's single-use only (case in point, today I'm installing a single window and foaming around it, and I'll need only a small amount for that). Couldn't a smaller can be produced for store shelves to minimize waste ? A lot of us are being forced to buy much more quantity than needed, and it gets thrown out. Wasn't there once a tiny can on the market ? I can't find them in my city....

Rated 1 out of 5 by from Dispensing straws ALWAYS break before the can is empty ! I have been using great stuff for years and it works, provided that the dispensing straw does not snap off. Of the last 20 cans I purchased over the last 5 years or so I've only managed to empty a couply of lousy can before the straw broke. I have 3 full cans on my shelf because the straws broke before I could even start dispensing the foam. The straws are very brittle and do not flex much. It constantly snaps where it attaches to the main body. It is a huge inconvienience when it breaks because it instantly stops the project your working on. I've been buying a backup can lately but it does not matter and you can't buy a replacement straw. Why should I have to buy two or even three cans just to get the project done that one can should have been able to complete. Great for Dows pockets, but not mine. I'm disgusted with the company for the intentionally poor design of its dispensing straw.

Rated 4 out of 5 by from Works great Great Stuff works well. I would suggest that users read the fan's directions prior to purchasing or using it. The manufacturer should consider producing smaller cans, say 6-8oz cans. (Not sure how cost effective this would be for the company to provide the consumer with this option). Having purchased the product several times for small projects it has been a waste of money and the can's contents for me.

Rated 5 out of 5 by from With care, an excellent value! This is actually a tip for those who've had trouble re-using the product. I use an air-siphon gun and blow a small amount of mineral spirits through my "straw" after use, which cleans all of the left-over product out, and allows re-use (you MUST do this before product sets up, however). Then, when you want to use the rest of the can, just use a clean deck screw to remove the small "plug" of hardened product out of the tip. I've been using this method for ten+ years, and it's never failed me.

Rated 5 out of 5 by from Never had a hose break. And I reuse. Not sure what people are doing to break these hoses so often, but I am just careful to not stress the small plastic junction and hold the flexible end of the tube, and have never once had a hose break. As far as reusing, here is what I do. After you are done, blow out the hose with your mouth into the trash. Then place entire hose into soapy water. The water will cause the sealant to cure within an hour. The foam will have expanded out both sides of the hose. Pull off the ends of the expanded foam. At this point, I separate the hose at the small junction. With the larger tube, I use large plumbers solder on a roll, which is almost exactly the same diameter as the tube, I just push the cured foam through the tube. On the small junction tube, I use a small roll of electrical solder and do the same thing. I leave the extra expanded foam on the can and when I decide to use it again, I just dig the cured foam out with a small screwdriver or toothpick, or whatever is handy. I always wear latex gloves when I use it, so I do not mind the mess. I use the gloves to push the foam into cracks even better! Just be gentle with the hose, and you will be good to go!

Rated 1 out of 5 by from VERY CHEAP NOZZLE After all these bad reviews of cheap nozzles snapping off, one would think a revision would be made, but no. Nozzle snapped immediately between the sprayer part and the long tube. I tried to remedy the pieces and as I'm twisting the nozzle into the can, IT SNAPS OFF! I am not a big strong man. I didn't "man handle it" So I am out the money for this and unable to finish my project. Again, maybe listen to the many complaints on your website and better your product. What a shame.
