Fomo Handi-Foam Polyurethane Waterfall Foam Sealant - 24 oz (gun required) (MPN P30251)

Handi-Foam Sealants can be used to simplify the construction of waterfalls. By spraying the sealants under and around the stones in the waterfall or stream, a water-resistant barrier is created. Once the sealants are dry, the water flow is redirected over the installed stones, resulting in more dramatic waterfalls. These sealants are specifically designed to seal and fill small cracks, gaps, and voids. They can be applied using a straw applicator, a professional dispensing unit, or a professional hose kit. Handi-Foam Sealants come in various sizes to cater to different application needs, reducing waste on small jobs and providing cost benefits for larger projects. When the Handi-Foam Sealants come into contact with ambient moisture or humidity in the air, they cure and form a rigid, closed cell barrier. This barrier effectively prevents drafts, noise, moisture, and air infiltration. The sealants become tack-free within 10 minutes and meet ASTM E84 Class 1 standards for caulk and sealants. Additionally, Handi-Foam Sealants are available in Fireblock, black, and standard formulations to suit different sealing requirements. The features of Handi-Foam Sealants include their faster and easier application compared to mortar. They expand to fill gaps and voids, making them especially versatile. The sealants can reach into tight spaces with the help of a nozzle adapter or an applicator gun. They are also fish-safe when cured, allowing for aquatic environments. Handi-Foam Sealants dry tack-free in approximately 10 minutes and fully cure in 24 hours. To apply these sealants, an applicator gun is required, and the Fomo Handi-Tool Dispensing Tool is recommended.
