About Flex Tape

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!

    Did not work

    I made sure everything was dry and free of dirt. I tried putting on PCV, I even tried adding layers, and it still did not stop the leak. The commercial can be considered false because, in my opinion, I just wasted around $13.00.

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

    Used it to help in weatherizing my canopy

    I recently purchased a canopy, to put out back of my house for shelter from the rain, wind, and snow so that I could smoke. I purchased it for the first shipping trip, 7 rolls of the white Flex Tape, to seal the outside of the canopy on top and all four corners, and I'm extremely impressed, and even went back to get 5 more rolls after seeing these incredible results for the first time using. I came up with ideas with turning it now into my very own little outdoor space to relax or whatever.

    I highly recommend the Flex Tape because it turned my canopy from an outdoor wedding canopy that wasn't intended for everyday use and not recommended for windy rainy and snowy weather, to my very own little outdoor woman cave that I can now go use anytime to escape my children, and even husband LOL.

    Thanks Flex Tape. I'm currently thinking of new crafts just to go get more tape.

    Fixing my pool

    • Mississippi,
    • Oct 5, 2017
    • Verified Reviewer

    I had two large gashes on the side of my above ground pool. I drained it and applied two strips to cover them. They stuck great but not much of it for $15 a roll. I found it at local hardware store. I filled pool back up, and there is still a slight trickle of water coming from the pool. I will be putting more tape over it to fix that, or is my 3-month-old pool a total loss?

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

    From thrilled to ripped off!

    I had just recently seen the ad for Flex Tape and was going to buy some for the workbench. So, yesterday, when I discovered water in my cellar, I searched all over to finally find the source to be a tiny pin-hole in a small section of copper pipe leading to an outdoor spigot, which I'd long abandoned. The copper was not very old and was still clean.

    When I found this, my first reaction was to regret that I hadn't ordered that Flex Tape! From what I saw advertised, this was the perfect situation. It was late, and I needed something to hold this tiny leak until I could cut and cap off the pipe in the morning.

    We went to our local Walmart to get a few things, and I picked up some piping tape. Then, on the way out, we saw an "As Seen on TV" section, and there was "Flex Tape!" We laughed, not believing our good fortune.

    Back home, I followed the easy directions, cut a section to fit the pipe, cleaned off the tube, and, with visions in my head of that guy on TV slapping the tape over a leak, carefully wrapped the pipe with the sticky tape.

    Did it work? NO! The instant it encountered any moisture, it lost all adhesion. It stuck to itself pretty well, and did stick to the copper, but all this exercise did was to create a sleeve that would direct the drip into a bucket I placed underneath.

    In all fairness, I believe this product can work, but only under dry, optimum conditions, but so will many other tapes. Were there no leak, and I wrapped this tape around the dry copper pipe, I'm sure it would hold, for a while. But why would I do that? I needed this product to work as advertised, and it did not. And I made no demands of it beyond how it was described by the advertisers.

    On a side note, we left the package of plumbing tape I'd picked up in hardware on the Flex Tape display near the check-out. I wonder if someone will take the hint...

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

    Rip off

    • Georgia,
    • Sep 10, 2017
    • Verified Reviewer

    What a rip-off. $50 for 5' of tape and a 2oz can that wasn't even half full. I will never use their product again. If I wasn't required to give it a star I wouldn't have. It took forever to be delivered, it must have come on the Pony Express. I don't even know if this product works because I'm so shocked by the quantity of it.

    Doest not work!

    We tried fixing a simple flat surface tear in the seat of our side by side, and it will not stick. We have tried two or three times following the instructions, and it comes right off. Don't waste your money.

    Horrible product!

    • El Mirage, AZ,
    • Aug 24, 2017
    • Verified Reviewer

    I purchased a roll of Flex Tape to fix a leaky copper pipe. I cleaned it as directed, applied the tape and watched the water come out from the sides. I removed it and repeated the process, only to see it still leaking and forming large bubbles until they popped like a water balloon!

    I contacted the company and was told to deal with the store I bought it from as far as getting my money back. I tried to formally to submit a complaint, which I was basically told, "Sorry about your damn luck chump!" They wanted no part of dealing with a disappointed customer.

    How can they say, "Proudly Made in the USA!" when they clearly don't care about their customers!

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

    Waste of money

    My husband purchased Flex Tape at Walmart to cob a very "pinhead size leak" in a bathroom pipe, and even though he used two pieces of about 3" each right over the leak, it's still leaking. I rate it a negative one star but was unable to do so.

    Quite an expensive piece of crap

    • Bountiful, UT,
    • Aug 17, 2017
    • Verified Reviewer

    So I bought the Flex Shot and the Flex Seal tape to try to repair a pool light (Flex Shot to seal the light and Flex Tape to hold in place while sealing). What a load of CRAP. Tape wouldn't stick to the pool's side under the water, so the whole thing about applying it underwater is not true! Flex Shot just came off and slid around the pool like an oil slick. Slid off like it was made of baby oil. $30 down the toilet before I finally bought some puddy that cost $15 which sealed it.

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

    Garbage

    • California,
    • Aug 15, 2017
    • Verified Reviewer

    I tried to use it for a patch on a pool liner. Once this crap gets wet, it immediately loses its stickiness. Never will this stuff work underwater, it is straight garbage. When you first get it and peel some off, it seems really sticky, but you will never patch the inside of anything filled with water. Phil is lucky that the boat didn't break in half, he wouldn't be saying "yeaahhh doggy!" That's for sure.

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

    Flex Tape

    I used Flex Tape to hold up a fallen rubber piece on my Ford. So far so good. I won't know if it'll stay up until I get it repaired but it's been good so far.

    I haven't tried it under water or any water type repair, so I can't report on that just it's staying up for me, and it seems pretty strong.

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