Flex Seal Flood Protection Coverage

This article will give you information on how to measure before a flood, and explain how you can estimate how much product you will need.
IMPORTANT
Always follow evacuation orders. Heed all directions from local government and emergency management officials. Watch our introductory video before starting.
IMPORTANT
Flood Paste in a Cartridge is the base coat for your first layer of protection. Use a gloved finger, Flex Gap Filler tool, or similar tool to push into all seams and openings to help create a watertight seal. Always be cautious of any sharp objects that may cause injury.

How To Measure
When you measure, make sure to measure not only the width, but also measure up, to a foot above the anticipated water level. In other words, you would want to measure in a 'U' shape, as indicated by the yellow lines in the image above.

• The coverage for one coat of the 9oz Flood Paste cartridge, applying a quarter-inch bead, is approximately 21 linear feet.

• The coverage for one coat of the 3 individually wrapped sleeves of Flood Paste, when applied 2 inches wide, is approximately 31 linear feet.

Remember once the final application has been completed, you’ll need to allow 24-48 hours for our products to fully cure before flood waters arrive.

Once you have the measurements, you can use our coverage calculator below to quickly estimate how much you would need.
