Review: Reliable and Effective Insulation Foam - The Great Stuff Pro Gaps & Cracks Insulating Foam Sealant has been a reliable product for my home improvement projects. This 24 oz can provides a generous amount of foam, which is great for sealing gaps and cracks around the house. The orange color makes it easy to see where the foam has been applied, ensuring complete coverage. One of the things I like most about this product is its ability to expand and fill even the smallest gaps, providing excellent insulation. It adheres well to various surfaces, including wood, metal, and masonry, and creates a solid seal that lasts. The foam dries quickly, allowing me to move on to the next step of my project without much delay. A minor downside is that the foam can be a bit messy if not applied carefully, but using the right applicator gun helps manage this. For anyone tackling insulation tasks, this foam sealant is an excellent choice. Its expansive properties, strong adhesion, and ease of use make it a valuable tool for sealing and insulating efficiently.
Review: This stuff is great ;) - Pros Absolutely adore great stuff. I’ve never used it in construction or plumbing settings, but it works great in aquariums/terrariums! I made the base of a terrarium background with it (WIP) and it held on well!! You can cut it off with a blade very easily, as well as just pull and scrape with your fingers. Very good at being waterproof though!! Cons If you don’t use the whole can in one sitting, it’s really hard to get the rest out (in my experience). I had to get a whole new nozzle just to use a can that was half empty, and even then it struggled. The insides were all dry foamed up! But if you use it all, great product. (And maybe I’m just dumb and didn’t do the reuse part right lol)

### ⭐⭐⭐⭐ Satisfied
*by M***E on February 22, 2018*

I was quite excited to stumble upon great stuff in black. I have not seen it available locally and it offered an immediate solution to a small out building/garden shed on our property. I applied it to the gap between the metal roof and cedar siding. You could see where foam had been used years before but the wasps had begun to easily enter last summer. I waited for a milder day this winter and had kept the foam inside the house for optimal results. The product worked, but I am not sure it is as sticky as standard foam. Several “worms” dropped to the deck below - which wasn’t an issue for me because it is to be replaced. If you are over something newer, I would probably use a drop cloth or something. It also didn’t expand as much as traditional gaps/cracks foam but that wasn’t a big problem either. The color is more of a shiny charcoal- in my application the over hand hides it but I can see situations where it may have to be touched up with a darker, flatter pain to make it “disappear.” Will definitely buy again, hopefully the commercial bottles will be available soon for use with a foam gun.
