Aquarium sealant repairs leaky aquariums, builds small aquariums and repairs broken ornaments. Aquarium sealant stays flexible, will not crack or shrink, is waterproof and harmless to freshwater and saltwater. Sealant releases acetic acid (vinegar-like odor) during cure. 100% clear silicone rubber. New sealant will not adhere well to old sealant. Sealant will bond in 24 hours. Allow 48 hours before filling aquarium, optimum strength is achieved in 7 days.

Caution: on contact, uncured sealant causes irritation. Remove from skin with a dry cloth or paper towel.
