The Aquascape Pond and Waterfall Foam Sealant is a fish-safe, black polyurethane expanding foam designed to maximize water flow in streams and waterfalls by sealing gaps between rocks and boulders. Ideal for both new builds and touch-ups, this sealant helps direct water over rock surfaces for more dramatic and efficient waterfalls.
Unlike traditional foam sealants that require a separate applicator gun, this convenient aerosol spray can makes application quick, easy, and economical—perfect for DIYers and pond professionals alike.
