The SECUR Low-Level Flood Protection System utilizes Flex Seal Flood products, which are specifically designed to work TOGETHER to create multiple layers of super-strong, waterproof protection, and to be easily removed after floodwaters recede. They can help slow down or even stop low-level water from entering structures.
Flood Spray is used as a final coat of protection to fill any small openings or pinholes that may have been missed in place of Flex Seal Liquid (when flooding is imminent and there is not at least an hour for liquid to dry). When used as a final coat, apply Flood Spray on top of all previous layers of Flood Protection products. We recommend you use Flood Spray as a top coating on our other Flood Protection products. You can also apply Flood Spray to seal hard-to-reach areas, such as seams, windowsills, small openings, corners, irregular shapes, and more.

When used as directed, our Flood Protection Spray has been independently verified by UL Solutions to hold back 3ft of water for 14 days on gaps up to ⅛ inch. Tested in laboratory settings.
Patent Pending for Products and Uses.
