Great Stuff Smart Dispenser Black Polyurethane Insulating Foam Sealant 12 oz

Great Stuff Pond & Stone Filler, Sealer and Adhesive is specifically designed to help quickly and easily build beautiful water features. By expanding to fill gaps and cracks, the polyurethane foam helps direct water to flow over the rocks in a waterfall rather than under and in between. Plus, the foam's black color means it's easily hidden among the rocks and shadows. Great Stuff Pond & Store can help improve aesthetics of water features, creating stunning landscapes. It can be used to set and secure the cap stones in retaining walls. A quicker and less expensive option than mortar, Great Stuff Pond & Stone is designed to bond porous and non-porous rocks or stones. It's an excellent choice for water features from fountains to koi ponds because it's safe for ornamental fish. New Smart Dispenser design eliminates mess and product waste by providing a precise application with no drips. The application is maneuverable and intuitive to use with a simple, trigger gun which saves time. The Smart Dispenser allows the user to reuse Great Stuff for up to 30 days.
