AquascapePond & Waterfall Foam Sealant, Black Polyurethane Spray Foam for Rock Gaps and Water Flow Control, 12 oz, 82002

I use this product in one of my outside rock waterfall features. Love the black as it blended in perfectly.

Great value and quality in easy use durable spray can.. fixed all my leaks

This is the best on the market. I tried them all. It’s the most natural and the most sealing. I’ve used for several projects. Recently used as a patch. Dropped water cleaned, foamed, dropped flat rock on it. Perfect

USE GLOVES!

I like that the colornis black a d blends perfectley with the.water fall stones.

When I get a leak in my pond it's big deal and I don't want to repeat the process within three weeks. I's hard to believe that this product is sold because it dissolves when something like a waterfall goes over it. unbelievable that this is sold as a foam sealant for waterfalls.

The cost was $20 and didn't go very far at all. To make it worse, it took 2 days to get the stuff off my hands. I mixed a little mortar and used that instead. Much cheaper, and locked things together better, and looked more natural than the foam.

I cannot screw it because tread was broken and was leaking from the start
