  • Held back water amazingly!
Style: 3.75" x 50', MAX
A definite need if you live in a flood zone! I'm still tryto figure out why FEMA, counties, and cities still tell people about sandbags. They don't work where FlexTape is magnificent! I live in a flood zone in Florida near Tampa Bay. We have 39' of new French doors along the back (waterside) where we added a 1000 s f addition. Taping saved our home during Helene and Milton! For Helene, neighbors thought I was overreacting, but, we never had to leave our house whereas most neighbors are living elsewhere still...7 months later! I told our county and FEMA folks to stop telling people to sandbag! FlexTape will save your home! I won't lie...it's a tough job to tape all doors, etc...up a few feet, but that's what makes adhesion work so well. I'm sure 67 y o with shoulder and numerous hand/elbow issues...but i did it. FlexTape...advertise on TV, internet, etc ..through hurricane season! I've been advertising for you (and another cheaper tape for other areas) to neighbors on the Next Door app. One lady asked that I remind everyone during storm season. ... show more

  • Works Great!
Style: 3.75" x 20'
Easy to apply, and tropes easily.

  • Caution...do not try to use this tape when the surface is even damp. It won't stick.
Style: 3.75" x 20'
Caution...do not try to use this tape when the surface is even damp. It won't stick. It always rains before a hurricane hits and if you wait to use this tape and the surfaces are wet or even damp, it will not stick. Otherwise it works perfect. Yes, it takes paint off sometimes, but the glue comes off with mineral spirits and you can repaint easier than dealing with a flood in your house. ... show more

  • Works.
Style: 3.75" x 50', MAX
Hard to apply to a surface that is already damp. It won’t stick. Make sure that you apply it to a dry surface.

  • Tape pulls off paint and is difficult to apply
Style: 7.5" x 50', MAX
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.

  • Cheap insurance policy for Florida home
Style: 3.75" x 50', MAX
Thankfully, I've yet to test the adhesion in a flood, so I can only comment on the installation and removal. I made removable flood dams for all my doorways in my Florida home. I place this tape along the channels that hold the dams in place, inside and out. The tape is easy to install and leaves no mess when I remove it. I pray I'll never have to put it to the flood test in a hurricane. ... show more

  • Saved my house from flooding!
Style: 3.75" x 50', MAX
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! ... show more
