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.

Q:Can this be used on HVAC ducts where they connect?
by|Apr 22, 2024
1 Answer
Answer This Question

A:  Hello Sbeck - Yes, but it may be difficult to seal a joint or seam with a spray foam that comes out of the can as a bead. You'll need to ensure the surfaces are clean and dust free to ensure that the foam will stick. There are better choices for this task, including foil tape. Easier to use than Great Stuff™ Insulating Foam Sealant.

        Q:How many cans would I need to buy to fill a space roughly the size of a 5 gallon bucket?
        by|Apr 16, 2024
        1 Answer
        Answer This Question

        A:  Hello Jason - Very difficult to say, we do not measure the yield of a can of Great Stuff™ Insulating Foam Sealants. We measure the yield in linear feet, a 12oz can of the Great Stuff™ Gaps and Cracks Insulating Foam Sealant, is estimated at 184 linear feet @ a 1/2" bead. Filling large voids is not a strong point of moisture cured one component polyurethane foam products. We do not offer a product that is suitable for this application.

          This foam works on many things. This time I'm using it to fill a brick hole in my garage before painting. I have to do it in steps because I never know how much expansion will happen, a little goes a long way.

          Great product!!! Wear gloves!!! Product not usable after initial application so be sure you use it for everything as you need the first time before it expands and dries.

          1.25 inches that’s all
          I purchased this product in the hopes of actually getting 3 inches of expansion, I got barely an inch and a quarter. Needless to say I’ll be returning the 3 unused cans. None of the cans were expired and the temp inside the bathroom was 70 degrees. Attached photo is from 3 hours later.

          Hello JimBob15812 - Thank you for sharing your concerns with us regarding Great Stuff™ Insulating Foam Sealant products. We apologize for any inconvenience you may have encountered. I don't know the specifics for your application but please note in order to get the 3-inches, you need to use a 1-inch bead. I did look at the photo you attached to the review, but it doesn't show the original bead size. If you have additional questions about your experience with the Great Stuff™ Insulating Foam Sealant products, please call us at 866-583-2583. DOW

            Worst product
            This stuff is super dangerous when it get stuck in you hand and it’s super hard to remove it . I wish they have a big note in the can to use gloves only when using .

              20 years later looks like new
              20 years later looks like new! It was used as a wall crack filler in my NYC loft. The 2nd picture shows how it deteorates when left unpainted exposed to air 20 years later.

                This product expands and tacks up quickly. It has filled gaps and cracks to seal out air, insects and rodents.

                Buy a can, use once
                PSA: when your old can of spray foam clogs, just buy a new can. Do not attempt to drill out the valve. Subscribe to my newsletter for more home improvement advice! The can does say, "Great Stuff can seal itself shut. One time use should be expected." And in my defense, I did unclog it with the drill. I just don't recommend it.
