Atlantic's FallsFoam fills gaps and directs water to flow over waterfall rocks rather than beneath them. This high-density, closed-cell foam resists foot traffic and waterlogging. Its black color offers reduced visibility, and it’s UV-resistant for long-lasting durability. Foam Cleaner swiftly breaks down uncured foam, keeping both the foam guns and surrounding areas clean. The LF1100 is a 12 oz DIY black waterfall foam can with an applicator straw, and it has a 1-year shelf life from the born-on date.
