Fomo Handi-Foam Polyurethane Waterfall Foam Sealant 12 oz (MPN P30053)

Handi-Foam Sealants can be used to simplify waterfall construction by creating a water resistant barrier. By spraying under and around the stones in your waterfall or stream, you can redirect the water flow to make more dramatic waterfalls. These sealants are designed to seal and fill small cracks, gaps, and voids, and can be applied using a straw applicator, professional dispensing unit, or professional hose kit. They come in various sizes to cater to different application needs, reducing waste on small jobs and offering cost-effective solutions for large projects. Handi-Foam Sealants cure when ambient moisture or humidity in the air reacts with the foam, creating a rigid, closed-cell barrier that prevents drafts, noise, moisture, and air infiltration. They have a tack-free time of 10 minutes and meet ASTM E84 Class 1 for caulk and sealants. With fireblock, black, and standard formulations available, Handi-Foam Sealants are the ideal choice for all your sealing needs. The features of Handi-Foam Sealants include being quicker and easier to use compared to mortar. These sealants expand to fill gaps and voids, and their nozzle adapter or applicator gun allows access to tight spaces. Once cured, they are safe for fish and dry tack-free in approximately 10 minutes, fully curing within 24 hours. It is important to note that these sealants are ready to use and do not require an applicator gun.
