## Overview

TotalPond Waterfall Foam Sealant is a single-component polyurethane foam designed for waterfall construction and pond repairs. It expands 2-3 times to fill gaps, adheres to most surfaces, dries tack-free in 5 minutes, and fully cures within 24 hours to create a durable, waterproof seal.

## Description

TotalPond's Waterfall Foam Sealant is a one-component, polyurethane foam, moisture-cured mixture used to fill, seal, and bond rocks for waterfall construction. It expands 2 to 3 times the extruded bead and adheres to many surfaces.

Review: 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.
Review: 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.
