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

Rated 3.9 out of 5 by 208 reviewers.
Rated 1.0 out of 5.0 by 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 2.0 out of 5.0 by 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. September 17, 2016
Rated 5.0 out of 5.0 by 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. October 1, 2016
Rated 4.0 out of 5.0 by works great, but plan well Works great. Just trust that its going to expand like it says and don't spray too much. Its easy to trim excess when hard. Make sure you plan ahead as once the spray solidifies in the straw, thats it, you'll have to buy another. April 26, 2016
