The Flex Seal Family of Flood Protection Products
Bring it on.
Floods are now the leading natural disaster on the planet. Help defend your home from rising water by applying our Flood Protection Paste, Tape, Spray, and Liquid to every opening of your home where floodwaters could enter.
Take it off.
All of our Flood Protection Products have been designed for simple removal once floodwaters recede.
Independently Tested by UL Solutions.
When used in combination and as directed, our Flood Protection products have been independently verified by UL Solutions to hold back 3ft of water for 14 days on gaps up to ½ inch.*
Includes step-by-step application directions.
All of our Flood Protection products come with a comprehensive application directions booklet, as well as a link to detailed “how-to” videos, guided by Flood Protection pros.
Depending on the opening to be sealed, use FLEX TAPE FLOOD PROTECTION in combination with:
FLEX PASTE FLOOD PROTECTION (CARTRIDGE)
Our primary Flood Protection product. 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.
FLEX PASTE FLOOD PROTECTION (WRAPPED SLEEVE)
Use on larger areas, flat surfaces, or directly on top of our other Flood Protection products. Great for basement widows, pet doors, crawlspaces, seams, windowsills, foundation cracks, and more.
FLEX SEAL LIQUID FLOOD PROTECTION
Use primarily as a final layer of protection to help seal any small pinholes or openings that may have been missed. Brush a generous amount directly on top of our other Flood Protection products. Each coat should be wider and overlaps previous layers of our Flood Protection products.
FLEX SEAL SPRAY FLOOD PROTECTION
Can be used as a primer coating, prior to applying our other Flood Protection products, or as a final coat of protection to fill any small openings or pinholes that may have been missed. Use in combination with our other Flood Protection products. Perfect for sealing hard-to-reach areas, such as door tracks, seams, windowsills, small openings, corners, irregular shapes, and more.

Hard to apply to a surface that is already damp. It won’t stick. Make sure that you apply it to a dry surface.

I spent hours putting this tape on my doors. We didn’t get flooded this time but I do think this product would have helped. The width makes it very difficult to apply. It also took all of the paint off my door.

Uses product for the hurricane we had. Seal the outside door with no problems. Order rose about 5 inches had a little seepage, but it was controllable in my lanai. After the storm was over went outside peeled it off no residue on my door. We buy again and we always use their heavy rain seasons if needed.

This is like duct tape on steroids. It laughs at rain - water in general. It can take the Florida heat and humidity without complaint. While it is a bit tricky to work with it is as close to permanent as any tape can get. Be careful to place it exactly how you want it, the very first time, or it will fight you should adjustments be needed. Sure it's quite expensive, but we'll worth it. If you need a tape that is all business this is the tape you should get.

I live in Florida and would highly recommend this product. I helps keep water from coming in around doors. It is a must to seriously reduce the chance of flooding around doors and windows.

I live in an AE flood zone. I have FEMA flood insurance. My home flooded 3x from 2020-2021 during flash floods due to poor city infrastructure and delays in improvements. I have 2 flood gates as do my neighbors and while they do help, they don't completely stop water from entering under front and back doors. I saw a commercial for the Flex line of Flood Protection back in July and purchased a roll of Flex Tape to see if it helped. Today we had flash flood warnings in the DC area and tons of rain in a very short time. Hastily applied this tape to the INTERIOR of my storm doors (some applied wet with the ongoing storm and still stuck just fine) to try and seal the gaps around the bottom portion of the door. Placed the flood gates between the 2 doors then closed the main door and taped along the inside as another barrier. Then waited and watched the water rising outside, frequently checking the doors for water. Nothing. Once the rainwater receded, stripped off the tape, opened the main doors to find the first layer on the interior of both storm doors kept the water out completely. Flood gates weren't even wet. Didn't believe it until I got outside and learned my neighbors only used flood gates and had water enter their homes. Immediately shared the link with everyone I could think of and bought 2 more rolls. Still amazed that it worked!

followed directions applied tape to a very smooth brick and submerged in a 5 gallon pale of water to see if it would stick. It did stick for a few hours so i left it over night and when i checked it the next morning the tape was no longer stuck to the brick. My house is concrete block so I dont think this will work well sealing the sides and bottoms of doors as they advertise. Will use sandbags and plastic if or when we have another major rain event. I tried again using sellers recommendation and let the tape cure on a piece of dry wood molding for 72 hours inside my garage . the tape adheared very well but after a few hours submerged in water the tape just fell off the molding. This tape would be useless in a flood situation and should not be sold as advertised. Dont waste your money on this product.
