Akonaflex Pro Self-Leveling Expansion Joint Filler is a superior-grade, one-component, urethane sealant and filler to be used in concrete joints as well as a wide variety of substrates. Its self-leveling characteristics provide a smooth finish which makes it ideal for filling cracks or gaps on horizontal surfaces such as concrete driveways, sidewalks, above ground foundations, patios, concrete steps, garage floors, and other concrete surfaces. Can be exposed to water after only 2 hours under normal conditions without washing out. It will reach full cure after 24 hours. Does not crack or shrink and thus acts as an excellent waterproof seal. Product should not be allowed to freeze.
