Aquamend is a hand-kneadable specialty epoxy putty that mixes in just one minute for permanent repairs to damp, wet areas and underwater applications. It will bond tenaciously to substrates such as fiberglass, metal, wood, concrete, glass, and many vinyls. After the final cure, Aquamend may be drilled, sawed, tapped, filed, sanded, and painted. Aquamend comes in a handy 4-oz. "tootsie-roll" form with the curing agent encapsulation in the contrasting base material. The unused portion will remain stable for years if protected from direct contact with the air.
