Product Overview

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.

Customer 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: Anonymous
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: Anonymous
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 3.4 out of 5 by 57.
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 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 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.

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 4 out of 5 by from Huge can and clogging means planning ahead As many reviews have said, the can is self-clogging. And the can is huge. I wish it came in smaller cans. I found it very difficult to line up all the various air sealing projects so I do them within the 2 hour timeframe. I ended up wasting 3/4 of the can. Had there been small can options that would have been much better. Imagine using 19 tubes of caulk in 120 minutes. That's what using great stuff feels like.

Rated 3 out of 5 by from Good Product, poor design You need to make your product reusable. I'm doing a remodel and I can't do all my sealing at once. SO MANY people complain that they wish they could buy just the straws. I'm not sure why you are not selling these also. As far as the product itself, it works great. Expands well and gets hard. I would give it 5 stars if I could use the can on more than 1 application.
