Fills in the cracks between rocks for improved waterfall appearance!  Our black expanding foam is one of the fastest curing foams available!  Dries to touch in ten minutes, cures in one hour.  Dries dark gray/black in color and blends into the shadow well.

Larger 20 oz. cans replace our 12 oz. cans!  This larger size is a considerably better deal per ounce than previous cans.  Self dispensing and reusable cans, ideal for homeowners or pond installers who do not use large volumes of foam.
