Q:Must this product be used all at once and can it be reused another day?
by|Mar 19, 2023
1 Answer
Answer This Question

A:  Hello Reusable - With the original straw design, it is best to attempt to use the entire can at once, as this design rarely restarts after being allows to sit for more than two hours.

    Q:Is this product non flammable enough and safe to use for sealing an opening around a gas pipe that enters my house from outside, in order to prevent rodents from entering my house through that same opening
    by|Feb 22, 2023
    1 Answer
    Answer This Question

    A:  Hello Jason - The Great Stuff™ Gaps and Cracks Insulating Foam Sealant is an excellent choice for your application. If you are trying to prevent rodents, we'd recommend the Great Stuff™ Pestblock Insulating Foam Sealant along with some metal mesh. Just spray a layer of the Great Stuff™ Pestblock Insulating Foam Sealant around the pipe and then embed some metal mesh into the wet foam. Allow the foam to cure and come back the next day and cover the area with another layer of foam.

      Answer This Question

      A:  Hello DennisZ - The Great Stuff™ Gaps and Cracks Insulating Foam Sealant is a minimally expanding foam sealant. It'll dispense as a bead of foam and will approximately double in size. This product will not expand like a spray foam insulation would, but the bead will expand.

          Works as expected.
          It does what it is supposed to and fills in cracks well. Got it for a good price at Home Depot. Very good at insulating and have found it to be the best solution to fill in holes made by woodpeckers in my siding. There are 2 big downsides. First, after the first use it will dry and clog the straw. There really is no good way to clean it out or prevent this from happening, so it is basically one-time use. Second, if any get on your hands or clothes, it is impossible to get off.

              Nasty Garbage
              I bought this on 2/20/23. It foams immediately so there is no time to fill the gap. It does not expand much so it basically poops out of every crack instead of filling it. It's impossible to wash off and the only reason it's gets on your skin is the simple fact that it does not work which makes you feel like you need to use a tool to push it back in. Such a huge mess it makes too! Garbage...use calk.

              Hello Nickname - Thank you for sharing your concerns with us regarding Great Stuff™ Insulating Foam Sealant products. We apologize for any inconvenience you may have encountered.
              The product is a minimally expanding foam. Gaps should be filled no more than 1/2 full. Gloves and eye protection should always be worn when using the product. Make sure to read and follow the directions on the back of the can. DOW

                cutting corners
                The product has been reduced in quantity and quality. The can's nozzle has been shorten, making it difficult to reach areas which it was intended for. I bought two cans at the local home depot and they both weren't good. The liquid was too water down not like before that as soon as it made contact with air the foam would expand. Do not recommend

                Hello fixerupper1 - Thank you for sharing your concerns with us regarding Great Stuff™ Insulating Foam Sealant products. We apologize for any inconvenience you may have encountered.
                On a side note, there is no water in Great Stuff™ Insulating Foam Sealants. These products are moisture cured polyurethane foam sealants, that pull the moisture out of the air to cause the curing process to occur. The blowing agent/propellant in the can is what pushes the product out of can and causes it to expand. We would recommend checking the best if used by dates on the bottom of the can to ensure that your product wasn't past that date. DOW

                    Worked Great
                    Worked great but foamed much more than expected and was harder to clean up as well.
