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. It’s paintable, sandable, and stainable
  • Cures as a cream colored, rigid foam. Ease of application results from all direction dispensing
  • One 16 oz. can equals up to 30 tubes (9 qt.) of caulk
  • Foam elasticity properties allows for movement and shifting within a structure
  • Seal and Save:

Rated 3.8 out of 5 by 177 reviewers.
Rated 5.0 out of 5.0 by Great Stuff Usage Tips In the past 6 months, I have purchased at least 2 cases of this foam. The expansive and sealing properties of this foam are incredible. I've used it to seal up drafty holes in the house, around leaky air ducts and inside new walls to keep moisture and insects on the outside. I've learned a lot about this foam and have some tricks I hope you can use. ALWAYS shake the can well the first time. The foam really does tend to settle in the can and needs to be remixed for best consistency. Make sure the trigger is tightly secured. I even check it from time to time as I use it. Be light on the trigger, especially the first time. There is a lot of pressure in that can and it the foam will escape faster than you'd probably like it too if you squeeze too hard. Try not to let the foam weigh itself down. It will start to drip and fall if you get too much in one section. That's when things get messy. If you have to, wait for it to start setting up a bit and then spray some more to fill in the remaining gaps. Get the nozzle as deep into the crack as you can. That way the foam really fills up the void from the inside out. Once dry, the foam can be cut easily with a sharp knife or razor blade. I have used it as a backing for caulk or even putty before and then sanded and painted over it. If you don't use the whole can, clean out the nozzle and store it. It can be re-used later.

Rated 5.0 out of 5.0 by Great solution to improve insulation and stop air flow Hello all: We used Great Stuff foam on a number of projects, and it is a great solution to seal gaps and cracks, seal the edges and joints in XPS insulation board, fill the hard-to-get-to spaces around HVAC ducts, etc. Here are a few tips: (1) Installation: Great Stuff is a one-component foam and cures by pulling water vapor out of the air. You can double the expansion by spritzing a little water on the surface before you spray the foam, and misting some more water on the foam after you apply it. Start by testing with a ball of foam on a piece of cardboard at your home / job site. (2) Foam board: Great Stuff is ideal to seal the edges and joints in foam board, e.g. if you install XPS foam board from Home Depot in your walls or between the raters in your roof. A photo is attached of a recent project, where we installed XPS in the walls of a house on the Cape in Massachusetts, and sealed everything with Great Stuff. (3) Windows and doors: Make sure you use the "Windows and Doors" version of Great Stuff to seal and insulate around windows and doors. The low expansion rate and flexibility of the cured foam are essential. (4) Fireblocking and hot surfaces: Cured Great Stuff foam will ignite at 240 degrees F -- including the "Fireblock" version. This is significantly lower than the ignition point for wood studs. DO NOT install Great Stuff next to any hot surface, e.g. a furnace, hot HVAC ducts, canned ceiling lights, a fireplace or chimney, etc. Rock wool and 3M fireblock sealant should be used in hot areas; both are available at your Home Depot. I hope this is helpful. Mark July 31, 2015
Rated 5.0 out of 5.0 by I am the spray foam queen This stuff is a God send once you get the hang of it. I live in rural VT and have used this on an old mobile home and a 200 yearold cape. If I listed all the uses I've found for it, you'd stop reading because the list is too long. It came in very handy to fill 1-2 inch gaps between 200 yo outer planking, so that we did not have to ruin the history and waste good wood to cover it with plywood (see pics) Messy? YOU BET- wear gloves and clothes you could throw away if needed. If it drips on you or anything else WAIT UNTIL IT DRIES then it usually picks right off. Ladies, even polish remover does not get this off your nails-wear gloves. Expands too much-Yes, use common sense, and read the label, if you need a product to fill where that is an issue, this is not it. HOWEVER- if you need a flat surface where you have sprayed it, just trim it off with a hand saw, or any serrated tool. I've used a tiling trowel, and a kitchen knife, to name a few. Using it overhead- get as high as you can, keep the can as vertical as possible and carefully bend the tube upward rather than laying the can horizontally. DON'T break the tube off or it will burst out all over you. Reusing a partially full can- for short term, a day at the most, stick a nail in the tube right after you finish, galvanized nails will pull some dried product out with them so they are good. For long term- use a sheetrock crew and drill it in there, you will have to drill it back out, but it last for months.. Make sure your nozzle is tightly screwed onto the can or it will dry out there.

Rated 1.0 out of 5.0 by Too messy and uncontrollable Sprays out of can too fast and too powerful causing too much over pour so that it clumps up in places. You cannot apply this stuff evenly making the finish look very ugly. It also doesn't stick to surface fast enough so that it drops off ceiling application and also drips down the wall when applied vertically. As you can see in the picture, this stuff falls off the ceiling before it can be applied. This stuff must be applied only downward if using it too seal along edges and even then it fills up too fast. About all that it is good for is filling up large holes and big cracks. If it came out of the can slow and steady and would stick immediately, it would be a better product. February 7, 2015
Rated 5.0 out of 5.0 by Plan ahead kids!! Think out of the can. I have used this to insulate cold spots in walls where the insulation settled. I drill holes thru the plaster 6-8" apart and squirt foam in til the tone changes. Have plenty of holes drilled and you will never have a partial can. After it is cured use something pointy like a potato peeler to remove excess at hole, fill with spackle lite and touch up paint. I insulated a very cold bathroom that was a porch in a previous life this way. September 23, 2014
Rated 4.0 out of 5.0 by Great product, but... This gap and crack foam sealant is great! It really does work and seals well from drafts and moisture. I've used it in my basement and outside shed. It's tricky to apply at first, but once you get used to how much comes out and how to apply it it's much easier. Fyi, it does expand about x5 as much as you squeeze out so be aware! They only downside to this product is that it's a single use design. If you've only used half a can, you can't save the rest for another time as the foam expands in the tube and blocks it. But for a one-time projects it's great! September 13, 2014
Rated 5.0 out of 5.0 by brando clay This stuff is great hence the name I worked as a sub contractor for a few years and got enough experience with this product had no issues what so ever a great tip that everyone should know when applying is you can reuse the straw applicator just pour some acetone down the straw wait a few seconds and it eats right through the foam I recommend you do it once your done dont wait too long it only works when its not cured December 23, 2014
Rated 2.0 out of 5.0 by Problem with spray tube Before you check out with this product , make sure that the spray tube attached to the can isn't cracked. The one I bought had half of the part of the tube that attached to the nozzle on the can cracked in a way that I thought it was required to add air to the product as it dispensed. It didn't look like a crack. But once I started using it, the foam came right out, then I tried to tape up the crack and it worked for a little bit, then the foam started coming out from underneath the spray attachment, Then I tried to use the can like a whipped cream canister with limited results. I could not finish the job because the tube was inoperable. I believe this is a packaging issue, the spray tube probably got cracked during shipping or stocking since the spray tube is just taped onto the side of the can. Still very disappointed since the product seems to work, but in the future I'll avoid this brand or package design. April 18, 2015
