Kraken Bond Black Spray Waterfall Foam Sealant - (2x24oz) Expanding Polyurethane Pond Foam Sealer Black, UV Resistant Insulating Spray for Landscape & Exterior, Gun Use, Gun Not Included, 2 Pack

Expensive but worth it

This foam sealant is fantastic—but you’ll probably need more than you think. Glad I went with the 12-pack. I’ve been experimenting with different ways to texture the surface: foil, wax paper, freezer paper, plastic wrap. Pro tip: don’t try to hold back the expansion with flimsy barriers. I learned the hard way—watched it slowly balloon into a giant bubble, then pop and shoot liquid foam several feet across the patio. Looked exactly like a giant zit exploding. *Sploogggh!* Absolutely hilarious. Only regret? Not catching it on video. Also, the Kraken Bond PRO Foam Gun - 8 Inch Durable Spray Foam Dispensing Gun is excellent and makes it easy to apply the foam precisely where you want. Good luck with your project. I think you'll like how this foam can help.

I liked the foam color, it is better than no color or orange when being exposed like in ponds etc.

Will not work with other foam guns!

worked really well. there could be better instructions for mixing. I think I used too much hardener in the first two jugs and may not have enough for the other two... really looks good and was easy to apply. Gun will never be super clean.

Got the job done. Used this to touch up and redo a portion of my pond less feature. It worked the same as the other popular brands but better priced. I'll definitely be purchasing this foam in the future.

The nozzle on these cans stick out further than the cans I have always used(Great Stuff) which meant trying to screw the can onto my gun lead to a huge mess. The foam was dispensing before the threads on the gun would engage. I’m using one of the many cheaper guns that Amazon sells in 3 packs, so it’s slightly possible a different gun might have deeper threads. But being there’s only a few threads to grab onto, I highly doubt a different gun would be designed differently. The resulting mess left me throwing away my gun and the full can of foam. I didn’t have any foam gun cleaner handy to spray down all the messy foam, so I’m sure it would be too late to clean it later once it cures. Aggravating, and also beyond my window to return the other can. So I’m out a gun and two cans of foam, and a setback on the job I’m trying to do. My included pic is of my third attempt to screw the can on, after grabbing rags trying to wipe off the excess foam.

I love this stuff and I buy a lot of it.
