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 Paste in a Cartridge is the primary Flood Protection product and should be used as a base coat for your first layer of protection. The cartridge nozzle allows you to target specific areas that need to be sealed. Use on windows, doors, garage doors, and all types of seams, brick moulding, thresholds, conduits, vents and ducts, door hardware (hinges and locks), and more.
Available in a Cartridge and Wrapped Sleeves.

• Screw on nozzle.
• Cut the nozzle to the desired bead thickness.
• Apply as much Paste as needed to completely fill seams/joints.
• Use a gloved finger or Flex Gap Filler tool to push Flood Paste into seams and onto adjacent surfaces.
