Great Stuff Insulation/Expanding Foam Pond & Stone Gap Filler - 3 Pack

Introducing the new Pond & Stone GREAT STUFF(TM) SMART DISPENSER. 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 colour means it’s easily hidden among the rocks and shadows. GREAT STUFF Pond & Stone can help improve aesthetics of water features, creating stunning landscapes. It can also be used to set and secure the cap stones in retaining walls. Helpful Tips Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down. Any uncured product that gets on the skin can be removed with acetone. Best results if used when product temperature ranges from 60-90°F (15-32°C). The can should not be exposed to temperatures more than 120°F. Cured foam should not be exposed to temperatures in excess of 240°F. Firmly screw straw assembly onto valve and dispense SLOWLY. Mist with water to speed cure. Trim cured foam with serrated blade. If applied outdoors, be sure to paint or cover foam to prevent discoloration and UV damage. Great Stuff cans featuring the straw tube applicator will seal shut if left to sit for more than 2 hours after its last use. If using GREAT STUFF SMART DISPENSER, follow these additional steps before application: Great Stuff cans featuring the Smart Dispenser may be reused up to 30 days with the straw left attached to the canister, just clean the tip after your first use. For best results: Thread the SMART DISPENSER onto the valve until it is secure, ensuring there is no gap between the dispenser and the valve. Do not unwind the dispenser after you have started using it. Let up on the trigger slowly to release pressure in the straw and prevent spurts during the next use and to achieve the most consistent bead.
