    The best way to cool it
    I used this kit today, insulating the one car garage walls on my house. It’s a great kit with everything you would need to do the complete insulation job. I was surprised by the amount of foam in each tube. The guns are of good quality, and the kit came with the nicest goggles I’ve seen in . Easy to load and use, and dries enough for a second coat in about 10 minutes. I misted the wood and concrete walls and the foam bonds to ANYTHING, including me. The results were instantly noted by the humidity level dropping 10 points within an hour of being done. I did the 2 outer walls, averaging about 2 1/2 or 3 inches. This is super good insulation, with a multitude of uses. It also has a pleasant green tint to it, Very satisfied with this item.

    Fear not The Thing fans! This goo hardens and protects you against the cold/heat! 😀
    This spray foam insulation is like giving your walls a big, fluffy winter coat, except it’s tough, airtight, and doesn’t complain about the cold. It expands quickly, seals gaps like a champ, and does a great job keeping drafts out and comfort in. Just be ready: once this stuff starts expanding, it doesn’t stop, so aim carefully unless you want your project to look like a science experiment gone rogue.In terms of quality, it feels solid (well, once it cures, literally). The foam hardens into a dense, durable barrier that’s water-resistant and firm to the touch. It doesn’t crumble or sag after drying, which is a big plus compared to cheaper alternatives. The nozzle works decently for precision, though let’s be honest—it’s spray foam, so you’ll probably still end up with a little “abstract art” around your workspace. A tip: gloves are not optional unless you want to spend the evening explaining your new “sticky fingers” look. Myself I bought a spray gun that attaches to these cans that is easier to clean and reusable for many more cans of the “goo”! :DDesign-wise, the cans are straightforward and user-friendly. The applicator straw attaches easily, and the trigger gives you decent control over how much foam you release. It’s compact enough to store extras without hogging your garage shelf space, but still feels substantial when you’re using it. The packaging clearly labels what you’re getting and doesn’t overcomplicate things—it’s very much “here’s the foam, now go seal something.”Overall, this is a dependable insulation product that does exactly what you need it to do: fill gaps, block drafts, and add energy efficiency without calling in the pros.It works great, cleanup is a bit of a pain (but that’s the nature of spray foam, not necessarily this brand’s fault). If you’re handy—or at least enthusiastic about trying—you’ll get satisfying results and maybe even bragging rights about your DIY skills.

    Y’allCanDiy PU Foam Spray – Single 1000ml Can (PACK OF 1 ONLY!)
    This Foam Spray is a handy solution for sealing gaps, insulating, and filling awkward spaces where other materials just won’t cut it. The 1000ml can packs a generous amount of expanding foam, and once it gets going, it really lives up to the “expanding” promise. It clings well to most surfaces and hardens into a durable barrier that keeps out drafts, pests, and the occasional nosy spider. Think of it as whipped cream for your walls, except it hardens instead of making dessert.Quality is solid, with the cured foam forming a dense, tough material that feels like it will hold up for years. It is water-resistant and offers good insulation value, which makes it great for both quick fixes and more serious projects. The nozzle works fine, but controlling the flow takes a little practice, since too much pressure can turn a neat bead into a foamy avalanche. Once hardened, trimming the excess is easy enough with a utility knife, but you will probably learn quickly why gloves are a must.Design is simple and straightforward, with a can-and-nozzle setup that most DIYers will be familiar with. There is no complicated equipment needed, just shake it up and spray. Installation is as easy as pointing and filling, though patience is required for the foam to cure properly. It is not glamorous, and you will not be bragging about how stylish your insulation looks, but in terms of function, it does exactly what it is supposed to do and does it well.With that said I need this to seal a rather large area of my Lab building here on the Ponderosa as to protect against particles and the normal heat/cold situation. 1 can, even as LARGE as it is didn’t do it or come close. So I bought a 3 pack along with it. Then I also bought a sprayer gun that works with these cans (see photos) to help me apply it more evenly. Now you can choose your own sprayer gun but this is about the spray foam itself. It sealed things tight and dried quickly. I will need more and thus why I bought the gun, though at first I might have shot myself because I wasn’t getting the application technique down, and then finally I did a bit better. This is a solid and good product!

    Does not stick well to surfaces
    Followed directions very messy and does not stick to surfaces very well. I sprayed water on the wall per the directions but it kept falling off. You need to make sure area is covered this will not come off!

    Great kit
    Amazing. Easy to use. My ac register showed a 68 (with ac on) with my thermal gun prior to foaming. After foaming the register (the attic side in case that’s not clear) it showed a 58 on the same thermal gun. Not an enormous change but after I do all my registers that will be significant. I also foamed a few of my sun tunnels and my bathroom fans. They all showed lower temps after foaming. Gun feels sturdy. Lots of tips to use.
