PROFESSIONAL BLACK WATERFALL FOAM

Professional Black Waterfall Foam is a high-performance, expanding polyurethane foam used by pond contractors and DIY builders to seal rocks, divert water, and enhance the visual impact of waterfalls and streambeds. Specially formulated in black to blend naturally with rocks and pond liner, this foam helps eliminate water loss by filling gaps between boulders and redirecting flow over the desired paths.

Unlike traditional spray foam, this professional-grade formula is UV-resistant, fish-safe once cured, and provides long-lasting durability even in outdoor environments. It cures quickly, allowing you to fine-tune waterfall structures and create dynamic water movement with precision.
