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

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.

works as advertised

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

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.

I purchased this solely because of the 30oz cans. I needed to fill a lot of cracks in prep for insulation. These cans last damn near forever. It expands and seals fairly well. It's good for what it does and the large cans work well.

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.

Hard to beat the price on this foam straight from Dow. I bought two cases for a remodel and love the stuff! I recommend buying multiple applicator guns because they don't last. Found some for about $15 each on the web (bangood) and just threw it away after spraying about 5 cans of foam. The 24oz cans seam to cover about 3 times as much as the cans with a hose. I covered every seam on the walls and roof sheets and lined each side of every wall stud, including every TJI floor and ceiling ijoist with about a case and a half! Also read that using this foam around the TJI joist and at the ends in the brackets increases the TJI holding strength by 4 times! This stuff is a sticky mess when applying so plan to where throw away clothes, but after it dries (overnight) it is much easier to remove any excess by just breaking it off.
