I used this on a natural stone waterfall to draw the water over the rocks because all of the water was it was running underneath them. I also used it to hide certain parts I didnโ€™t want visible and to help maintain the structure of the stones to keep them from moving. It worked great for this, and overtime the color of the foam even took on a natural look that appeared more like the natural earth than the foam itself. This stuff really goes a long ways too, and marks much better with a gun than these typical cans with the built inattached sprayer. Iโ€™ve been thoroughly impressed with it. I would definitely recommend it to anyone looking to use it for DIY waterfalls ponds, creeks, etc.. just a note for those who may be unaware, be sure that you purchased the proper dispenser as well as foam gun cleaner. These can be found here on Amazon as well.

This is exactly like foam always works, but black. Great for underbelly of RV's. Wear disposable nitrile gloves. It'll come off with acetone before it cures, but after cure you'll have to wear it off!

have no idea if its any good or not, every single can of spray foam I have bought on line has come with an applicator tube. This product at the bottom of its description says "requires applicator gun". Forget that, I was just looking for a black spray foam. Deceptive description. PUT IT FIRST THAT IT IS NOT A COMPLETE PRODUCT.

After using other AKFix products, I was looking for a UV resistant foam to seal a gap between two joined metal buildings. I guess I'll take the blame for assuming it expanded. But, unless it is in really fine print on the can or in the description; it doesn't describe what sort of expansion this product has at all. Most other canned foam products give you some sort of idea on the expansion rate and/or how many board feet of foam is in the can. I supposed it's good for whatever it's intended for...maybe to seal roof penetrations in RV's since it talks about that. Anyway, some sort of indication of expansion rate should be more clear on the can or the company website.

Most of the negative reviews are from people who got this stuff free on Vine and were disappointed they needed a gun. The canister's enormous for the amount of product, which probably gives it the pressure. Works fantastic.

The foam came out pretty smooth but it needs a spray tip to make a smother spray. I wish there was a tip to put on the gun, vega spray comes with two spray tips

I used plenty of other foams in the past including Kraken brand. And I do have to say this AKfix 892P works very well even in tough angles foam is shooing out which surprised me. I even had it upside down for a few short burst areas and it delivers very well. Also the amount of propane to foam it very good just ensure you spray at slow to medium range with it. Towards the end of the can you should let the can settle and reshake to get the rest out of the can as well. Overall very good product. I will be using it more where I can take photos of the product installed.
