TotalPond 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

Good product easy to apply, expands a lot 10-15 mins after application and blends in well with pond. My only complaint is that it doesn't go as far as I thought it would. In hindsight I should have bought the bigger cans. Be aware that you only need a small amount as it expands bout 20 times it's volume. All in all a good product and I recommend it for all pond or landscape use.
