The same foam we use on every Southern Waterscapes build. Aquascape's Professional Black Waterfall Foam is the industry standard for sealing gaps and voids between rocks, boulders and liner - directing water exactly where you want it and keeping it flowing over your stones rather than disappearing underneath them.
This is the professional grade 24oz can, equivalent to five standard DIY foam cans. It's low expansion, high density, and specifically designed for water feature construction. The black polyurethane formula blends naturally into your rockwork so the seal is invisible once cured.
Quick curing - immersible within 15 minutes. Fish safe and non-leaching. Won't crack, yellow, or break down over time. The specially designed can creates an air and moisture-tight seal between uses, so nothing goes to waste between applications.
Requires a Foam Gun Applicator (sold separately). Foam Gun Cleaner required when switching to a new can.
