The SECUR Low-Level Flood Protection System utilizes Flex Seal Flood products, specifically designed to work together to help slow down or even stop low-level water from entering structures. Flood Spray is the final coat of protection to fill small openings or pinholes that may have been missed by other Flood Protection products. It can also be used in situations where flooding is imminent, and there isn't at least an hour for Flex Seal Liquid to dry. Flood spray is ideal for hard-to-reach areas, like seams, windowsills, small openings, corners, irregular shapes and more.
