GREAT STUFF Gaps & Cracks

Great price works great love it

This is a fantastic product that expands and once dries is just like Styrofoam and expands to fill the cracks and then can easily be broken off or cut off with a razor or whatever and is very easy to work with... ONCE CURED. Here's what you need to know though 1) WEAR GLOVES. Really! I REALLY mean it. This isn't one of those things that its some technicality. It's bad enough to where it really should have a critical warning on it. Why? Basically, unlike 99% of everything else in the world, this will NOT come off your skin with soap and water. No scrubbing will remove it. Don't believe me? Google it and read how people have removed it from their fingers. I'm literally talking about things like using a grinder. Don't use your good gloves either as they'll get ruined. Get a box of disposable gloves! 2) See #1. Yes, it's that important. 3) It CAN be messy. Its not necessarily messy by itself, but when you're trying to fill in big holes and it keeps expanding you will probably use too much and have to clean it up. While using gloves (again), you might want to use some towels to quickly clean it up or just plan on trimming it later 4) It's one time use. There's a bunch there, but its not for a one-time-experiment thing. Locate all of the places that need done and then do them all and use up the can 5) Its that ugly, trademark yellow. Why can't they come up with a white version? It'd make it unnoticeable in many scenarios.

Works great for stopping drafts and sealing areas where rodents are able to enter.

This is my go to for insulation and gap filling. Once cured, it's perfect. Just two things to keep in mind: 1. Don't get it on anything you want untouched by foam. It's tenacious and sticky, and getting it off your skin is a chore. Wear gloves. 2. Once you start using a can of it, use as much as possible, because using it again after the foam dries in the tube is pretty much impossible.

The only thing I don't like about this stuff is if you just need a little bit and then you store it away you can't use it once that stuff hardens up in the spray nozzle so what I did this time was I made sure to clean out the excess material out of the nozzle in the can itself as well as the straw with an air gun hopefully that preserves it for the next time I need it since this is a massive can

easy to use, dried quick with a decent appearance. could be cheaper but hey its 2025 what do you expect.

I used to handle product liability claims for Dow chemical, the manufacturer of “great stuff”. When sny reviewer says WEAR GLOVES!…you need gloves or your looking at skin burns if the product sticks to your skin. Water and soap aren’t enough. Sometimes hospitals do “surgery” to remove the foam. If it’s on your clothes, throw them out. It won’t come off in washer and might make your clothes worse depending on wash cycle temp. I received no less than 300 claims for this “great” stuff. People getting on their skin on their clothes. Not expanding enough to completely fill a persons gap in the house. Don’t buy got a home repair business either. You’ll end up with work comp claims and liability claims from employees/customers. Honestly considering how many injury cases I handled I shouldn’t even consider this to fill outdoor gaps where mice can get in. But I am ahead of the curve knowing I need to double or triple latex glove both hands.

After using all that i needed, I still have half a can! (wear some kind of gloves when spraying) This spray foam is among the best I've ever used. I had an issue where there were cracks in my walls and air was coming through from the outside (for reference, it was 30 degrees outside). My main living area would be around 72 and my room would be around 60. Really bad. The spray nozzle on the foam got right into the tight crack and very easily expanded in my walls. I felt a woosh of cold air as it pushed the last of it out of the wall, and now my room is about a 1 degree difference from my main living area. I was very surprised with how well this stuff worked at keeping out the cold. This is no replacement for insulation, but it will definitely help in the meantime! Wear gloves when spraying this, sometimes the foam leaks through the top of the can, but that was a minor worry for me.
