Flex Tape is straightforward to use in about four simple steps. First and foremost, cut the Flex Tape to your desired size using a razor blade or a pair of sharp scissors. Secondly, remove the backing to reveal the adhesive inside the tape.

Thirdly, apply the Flex Tape onto a clean surface while pressing down firmly to drive out any bubbles or pockets of air within the tape. Lastly, give the tape time to bond to the surface. The bond gets stronger with time, and the tape cannot be repositioned once applied.

The durable adhesive tape drives out air, moisture, and water from any surface to form a super strong waterproof barrier. Unlike other available tapes, the Flex Tape bond increase with pressure and time.

You can buy As Seen on TV Flex Tape at places like Amazon, Walmart, and Home Depot. Reading Flex Seal Tape Amazon reviews is highly recommended prior to making any tangible purchase. I recommend Amazon because they offer the best prices and discounts.

How to remove Flex Tape?

We’ve learned that Flex Tape bonds become stronger over time. However, a lot of customers have been successful in removing Flex Tape using adhesive remover or a citrus degreaser. To remove a dried Flex Tape, scrub it with a damp rag and acetone. A heavy duty scrub with a little elbow grease can disrupt the Flex Tape seal for easy removal.

Can Flex Tape be removed?

Although the Flex Tape bond gets stronger with pressure and time, you can still remove it successfully. You can combine kitchen degreaser and spray to remove the Flex Tape seal. I used a sharp paring knife to peel off one layer at a time while spraying it to distort the bond.

I’ve also used the Flex Tape remover to remove the toughest seal. It’s a portable, convenient, and easy-to-use aerosol with a rapid-acting formula that removes the toughest of adhesives. Flex Tape remover is excellent for removing Flex Tape, glue, decals, tar, graffiti, and more. It leaves no sticky residue if wiped clean.

Although it won’t grip on certain plasticized surfaces, the product proves useful on a wide range of surfaces. This product is worth it, and I hope this Flex Tape review will help you make an informed purchase decision for yourself.
