About Flex Tape

By HighYa Research Team
Published on: Jan 19, 2017

Flex Tape rubberized, waterproof tape features a triple thick adhesive that the company claims grips on tight and instantly creates a watertight seal to patch, bond, seal, and repair almost anything.

The waterproof tape can be used on just about any material, including PVC, acrylic, metal, wood, ceramic, glass, rubber, fiberglass, stucco, plaster, stone, and drywall. It also works under water and can be applied hot or cold.

Whether you need to repair an inflatable pool, a leaky pipe, a roof in the middle of a storm, or a pool or spa without draining it, this means product's company claims to provide a solution.

But does it really? Or, is ths tape another product that looks great on TV but will disappoint you after arriving on your doorstep? We've compiled what we learned during our research, so you don't have to waste your time and money on anything but the best.

How to Use Flex Tape: Are There Any Surfaces It’s Not Suitable For?

The process works over four steps:

  • Step 1: Using a pair of sharp scissors or a razor blade, cut to the desired size.
  • Step 2: Remove the backing, which will expose the tape's adhesive.
  • Step 3: On a clean surface, apply while pressing down firmly and removing any air pockets or bubbles. Once applied, it cannot be repositioned.
  • Step 4: After application, the bond will only get stronger over time.

While this product is useful for a variety of different surfaces, the manufacturer notes that it might not adhere to highly plasticized materials, siliconized or water repellent surfaces; surfaces that are greasy, oily or dirty; porous surfaces, and some fabrics.

Additionally, the adhesive can become gooey and lose its grip at temperatures exceeding 200° F, so it’s not for use around engines. Also, due to the high pressure involved, you can’t use Flex Tape on car or bike tires.

Finally, it’s important to point out that adhesive bond is only intended as an emergency, temporary repair, and should not be considered a long-term solution.

Is Waterproof, Rubberized Tape Common?

We're not told a whole lot about Flex Tape, including the material it’s made from or its thickness, so we can’t know exactly what you’ll get for your money.

However, if you type the phrase “rubber tape” or “vinyl tape” into any search engine, you’ll quickly learn that this tape has a seemingly decent level of competition.

What’s more, you can find this competing rubber/vinyl tape in just about every imaginable color, width, and length, so your third-party options might represent greater flexibility.

Pro tip: Keep in mind that what we’re talking about here is thick (usually a minimum of 4-6 mil) rubber tape with industrial strength adhesive. This is in contrast to much thinner, less sticky options like electrical tape.

From a price perspective, competing rubberized tape is generally priced between $10 and $20.

How Much Does Flex Tape Cost?

Available in black or white, Flex Tape can be purchased in three different size rolls:

  • 4” x 5’: $19.99
  • 8” x 5’: $29.99
  • 12” x 10’: $49.99

Whichever option you choose, you’ll be charged $9.99 S&H. You can also purchase a bonus can of Flex Seal, Flex Shot, or Flex Seal Liquid at checkout for an additional $9.99 fee.

All purchases come with a 30-day refund policy, less S&H. Keep in mind this means the fee you pay for the additional product will also be lost if you request a refund.

To do so, customer service can be reached at 844-531-8900.

Is Flex Tape Your Fix-It Solution?

There clearly seem to be a lot of instances where Flex Tape could come in handy. This might be especially true for water-related repairs like quickly fixing an inflatable, patching a pool, or repairing a leaky pipe.

In short, we can think of hundreds of different scenarios where having a roll of Flex Tape handy could be beneficial.

In the end, though, we’re not so much concerned with Flex Tape’s functionality or usability, as we are about the level of value it’ll provide because you may want to take a peek to find various sized rolls of vinyl tape at your local hardware store, often for meaningfully less than Flex Tape.

To add to this, due to Shipping & Handling charges, it is our opinion you may want to explore purchasing this product or similar ones at a local store to have a more-straight-forward return process if you're unsatisfied.

Finally, other products in the Flex lineup, including Seal, Shot, and Liquid come with 2-star average ratings or lower from HighYa readers, who frequently complained that they didn’t deliver on their promises (or if they did, that they soon stopped working). Many also complained that they were charged more than expected.

The good news is that if you’re dead-set on placing an order for the adhesive bond, the manufacturer seems to stand behind it with a 30-day refund policy. As mentioned before, though, just watch out for those non-refundable S&H fees!

    Flex Tape

    • Nebraska,
    • Sep 16, 2019
    • Verified Reviewer

    The commercial shows them slapping it on a big leaking hole in the side of a pool and it appears to stop the leak instantly.

    I followed the directions to the letter and it was worthless in fixing a small leak in a pipe. I even put multiple layers on.

    The second it got wet the adhesive stopped being sticky. I am very disappointed.

    Bottom Line: No, I would not recommend this to a friend

    THIS TAPE IS GREAT

    I had a leak under my kitchen faucet. I'm retired on a very strict budget. I wrapped the leak in Flex Seal Tape. IT WORKED! Its been 2 months and still good. I am more than excited that I didn't have to pay a plumber, $125.00 base fee, more for parts.

    It has worked wonderfully for me.

    Bottom Line: Yes, I would recommend this to a friend

    Tape does not work. Sealed pipe under the sink. Not worth the $12.00 we lost buying it. Opened box, instructions say peel off backing. CAN NOT peel. Watched several videos and it did not explain anything to help. This stuff is a sham. Money lost.

    My boat broke

    • Michigan,
    • Aug 6, 2019
    • Verified Reviewer

    So before I bought the tape, I saw a video of Phil Swift saying it would fix a boat if there was a hole in the bottom. I decided to cut a hole in the bottom of my boat and try it. Turns out it didn’t work and changed the dimensions of my boat. Complete rip-off and false advertising. Would not recommend if you cut holes in boats. Safe shopping!

    Bottom Line: No, I would not recommend this to a friend

    Don't believe the commercial

    • New York,

    Like other people have previously said, it doesn't work on a garden hose. I have a tiny hole in my hose. I tried Flex Tape twice. The hose still leaks. Hard to believe that they say it will stop a two-inch leak in a pool but won't stop a tiny little hole in a garden hose.

    Small leaks in pools

    • Wisconsin,

    After spending $24.00 for Flex Tape because it is said that it's waterproof, it does not bond to kid's swimming pools, very poor quality. I tried both inside and on the outside with no satisfaction.

    I paid over $13.00 for a 4" X 5' roll at Lowe's to fix a leak in my pool underwater and this stuff is worthless. Money thrown away, it did not stick underwater, it's supposed to stick to anything, but it didn't stick to vinyl pool liner. Don't waste your money.

    Had a small leak in a vinyl swimming pool, saw this ad on TV about working in water. Well, let me tell you, we drain the pool, put a patch on the inside of the liner and also one on the outside of the pool, then refilled and this am...the pool is still leaking. Was a waste of my money.

    Terrible!

    • Missouri,
    • Jul 20, 2019
    • Verified Reviewer

    This tape won't even stop a small leak in a water hose! Yes, I let the hose dry out and even let it sit 24 hours after I taped it. It held for about 5 seconds, then was leaking again! You'd be better off using duct tape! The commercial they have cutting a boat in half then using flex seal to put it back together, I'm absolutely sure that boat SANK within a matter of minutes!

    Bottom Line: No, I would not recommend this to a friend
