Rocking Foam is a minimal expanding foam for sealing cracks and crevices in streams and waterfalls and diverting waterflow. Minimal expanding foam. Better density for secure rock placement. Better control during application. Less waste – less foam to trim away. Patented dispersing trigger. Dispenses in any position (even upside-down!) Reusable system (system allows multiple uses from same can). Black color. Carbon used for the black color; not dye. Reduces ultraviolet deterioration of foam. Blends quickly with rocks and disappears behind flowing water. 100% safe for aquatic plants and animals. Non-toxic. Fish safe. 20 oz can is the right size for the job (no one uses just one 12 oz. can when creating a water feature). Better value – larger can allows lower unit cost.
