Waterfall Foam Sealant

Model # A16523

Our Waterfall Foam Sealant is single component polyurethane foam that is applied using an easy-dispense pressurized can. The moisture cured sealant is then placed between the liner and natural rock when you build your waterfall.

The black foam integrates with the landscape and flawlessly becomes part of the water environment. Fill crevices 1/3 full and allow the foam to expand and completely fill the spaces. If the gaps are larger than 3 inches, make sure to wet the substrate before you fill with foam. The Waterfall Foam Sealant takes about five minutes to dry tack-free. You can shape and cut the foam just one hour after it is dispensed. The compound cures in 12 to 24 hours. Leave it untouched until it’s cured, at which time it can be trimmed or sanded. Paint or stain the foam if it is exposed to the sun.

***Please Note: The foam is extremely flammable while dispensing. Wear protective gloves, clothes and eyewear during the application procedure. Cover and protect surface areas when sealant is applied, and store the container at room temperature. Nozzle tip applicator included with Waterfall Foam Sealant.
