Our Flood Paste in a Cartridge starts out as a thick paste that can be pushed deep into all types of openings and hard-to-reach areas. It dries to a strong, flexible, rubberized barrier. It seals out water, air, and moisture and remains completely flexible. Once floodwaters recede, our Flood Paste can be easily removed.
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, casings, thresholds, conduits, vents and ducts, keyholes, and more.
When applying our Flood Protection Paste in a Cartridge, always to push the Flood Paste into all seams and openings using a gloved finger, Flex Gap filler tool or similar tool. This will help create a watertight seal. A common mistake is not pushing the paste into the opening being sealed. Always be cautious of any sharp objects that may cause injury.
