Waterfall Foam Sealant

Fantastic item, not my first time using it. I've used it for wall filling in my pond. This time I used it for my aquarium for a backdrop. It's sticky coming out so absolutely wear gloves, it initially expands a small amount, but let it sit over night and it will get to about double the size of initial expansion. Great for filling cracks nearly an inch wide in my pond wall. Dries to be a sort of light grey.

Worked well!! Stopped the leak in a bout 3 hours time after curing

This Black colored expanding foam is just what I was looking for. I used 5 cans to create a background for my paludarium. Sprayed over chicken wire structures. See pictures. Actual color is gray but the product does exactly what it should. I warmed the cans up before shaking really good. Spray upside down.

Good

I use this product to create aesthetic 3D backgrounds in my reptile terrariums. For that purpose, it works very well. I like that it sets up within a few hours so I can start carving the surface sooner. Sticks well to glass. My only complaint is that it takes 3 cans to cover 80% of the back of a 67 gallon enclosure (18x24x36”)
