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.

  • Forms a permanent weather-tight seal to minimize drafts and insect infestation and has exceptional adhesion to building materials
  • GREAT STUFF gaps and cracks can be used in interior or exterior application and is tack free in 15 minutes; trims in 30-60 minutes
  • Cures as a cream colored, rigid foam
  • One 16 oz. can equals up to 30 tubes (9 Qt.) of caulk
  • Foam elasticity properties allow for movement and shifting within a structure
  • Paintable, sandable and stainable

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 3.9 out of 5 by 209.
Rated 1 out of 5 by from New "anti drip" valve is not all that I've used hundreds of cans of Great Stuff and have always been happy with the results more or less, but they have introduced a new "anti drip" feature to the delivery straw that does the opposite of what it was intended. There are no instructions on the cap where the new feature is proclaimed, but apparently you need to pull the end of the straw to open the valve. Otherwise, the pressure builds inside the straw and at the slightest movement the straw un-threads from the can and there is a miniature explosion of foam at the top of the can you need to clean up, in my case off of my face since I had tucked my head neatly between the gas line and the water line in the joists of my basement ceiling.

Rated 5 out of 5 by from Easy to use As a DIY kinda gal, needed this to fill the gap around my bathroom pipe so that creepy crawlers and draft won't occur anymore. Twist on nozzle, make sure your arm,eyes,hair is covered/protected..then spray away. Sprays and dries an ivory tone. Expands very quickly in humidity (shower steam). I got a smidgen on my finger. Used acetone/nail polish remover to take it off because it started to get tacky/sticky. I didn't need to use even 1/4 can, and I didn't want the rest to go to waste. SO, I used the acetone to unclog the spray nozzle by pouring a few drops in both ends then tapping it gently to loosen the goo. I also cleaned the black opening on the can itself. Brand new, unclogged,ready for use again in the future. I also read on the web goof off works too if you don't nail polish remover.

Rated 4 out of 5 by from Great gap and filler for spaces Read the directions and made sure to wear rubber glove, eyewear and proper clothing. Make sure it is used as recommended, as it will last longer. Do not use upright.

Rated 2 out of 5 by from Ugh! Not Worth It I had hoped to have success using Great Stuff to seal a 3" deep by 1/4" wide crack between rigid foam and studs. The reality is the spray sputters out making it very difficult to apply in any controlled manner. You would think it would work reasonably well. But frankly between an inconsistent application, spotty seal, the mess it creates, and the disappointing coverage, Great Stuff is not worth it. An 8oz can did uneven job of about 18' of crack before sputtering empty. For those thinking they can create a seal between rigid foam and studs I would strongly recommend cutting the foam a 1/16" over size and use a mallet to fit it in tightly. Use another manageable sealant if you need.

Rated 5 out of 5 by from It is Great Stuff Used for sealing around a basement exterior door. Read from other treads that you can save the can and applicator straw by cleaning out. When done, immediately remove straw and spray with WD40 to dissolve the foam in tube and trigger. Then use compressed air like the canned air for your computer to blow the straw and trigger clean. On to the can, pull out whatever foam is coming out and spray WD40 into the nozzle, then hit with air.
