GREAT STUFF PRO Gaps & Cracks 24 oz Spray Foam Insulation Sealant | Pack of 12, Closed Cell, Polyurethane, Fireblock, Expanding Spray Foam Sealant, Insulates & Seals Gaps Up to 3"

Name says it all ! Great stuff

Compared to the disposable cans with straws these are much better. The gun orientation makes it easier to use for me including getting into corners. These contain twice the product as those disposable cans and you can actually re use what's left later which is virtually impossible with the other cans. It does require the applicator gun and your also going to want a can or two of cleaner but it's worth it for the reusability.

It works, but we have way too much.

Foam is fireblock ORANGE (which is what we ordered and it should be). Use these cans with reusable foam gun.

I'm working on insulating parts of my house and this was a great deal. Thankfully, all the cans arrived intact and there weren't any issues. Each can worked perfectly. If you have a large project in front of you, I recommend this!

It works great as a gap filler. If your looking to do a spray on application this is not great stuff. It will not stick by itself. If your looking to fill gaps and cracks it is great stuff.

So I have been working on my unfinished upstairs and I have purchased 2 cases of the Great stuff Pro cans. The only issue I had was one can malfunctioned on a Great Stuff gun. Since, I had no issues with and off-brand gun I blame Great Stuff. The larger cans are perfect for lots of sealing.

It says it and the name, GREAT STUFF! Though it is pricey it's value will pay you back in the long run. If you purchase the injection gun made for these cans each can will go a long long way! I bought a case of cans and the injector and I'm still on my second can. There's not a crack left in the house or foundation. This product is not your every day but the store this is superior you you've used before having the ability to work it in there like a welder or a painter filling gaps and cracks little to none is wasted.
