Flex Tape Reviews – Ultimate Buyer Guide

Flex Tape Reviews – Ultimate Buyer Guide

Owners of boats and personal watercraft know that cracks and leaks aren’t always easy to repair. Some can require the assistance of an expensive professional and others can compromise the buoyancy of your vessel permanently.

However, some minor cracks can be repaired quite easily. If you aren’t ready to buy an entirely new ski boat or touring kayak, for example, it pays to know how to fix cracks so you can buy yourself more time.

Flex tape is one of the best products out there for repairing pontoon boats, kayaks, and even ski boats. It’s a simple solution for fixing small cracks and leaks without having to perform a more costly (and more time-consuming) repair.

In our Ultimate Buyer Guide, we will provide several Flex Tape reviews detailing their various products and the kinds of repairs they are meant for. So let’s get started!

What is Flex Tape?

In terms of its appearance, Flex Tape looks a lot like duct tape or Gorilla tape. It comes in rolls of various sizes, but it contains a more powerful adhesive than either of these two tapes and it is specifically made for the purpose of waterproofing.

It comes with a flexible rubberized backing that is thicker than most other tapes. It is also designed to contort and conform to almost any shape or surface imaginable, including underwater applications.

It is resistant to ultraviolet radiation and free of volatile organic compounds (VOCs) while also being resistant to extreme temperatures and weather conditions. What’s more is that the strength of the tape is designed to increase with time and pressure.

Flex Tape works on almost every surface you can think of as well. So if you don’t use a full roll to repair your boat or kayak, you’ll have leftovers to fix plumbing issues, roof leaks, shower repairs, and much more.

Flex Tape is also available in a variety of shades: white, black, clear, and grey. This makes it easier for you to match the color of the surface you’re repairing so that it’s hardly noticeable once you’re finished.

Who Is Flex Tape For?

The short answer really is anyone and everyone. It’ll help you repair everything from those pesky air mattresses that never seem to hold to a crack in the windshield of your boat.

Its versatility makes it an exceptional choice for the experienced or beginner DIY enthusiast and it’s the perfect replacement for the repair kit that came with your inflatable products. Sometimes, you might even consider throwing that old repair kit out and just keeping Flex Tape handy, depending on where it came from.

Flex Tape is also great for outdoorsy folks because it is so much easier to apply than other methods. Hikers and backpackers can use it to repair their packs and other gear that breaks down on the trail.

Kayakers and paddleboarders can use it to stay afloat or to patch a cracked paddle. Even car mechanics have been known to keep a roll of Flex Tape around to repair cracked lights or mirrors if clients aren’t ready to replace them.

Long story short, Flex Tape is for everyone. This is an essential item to keep in your garage or in your gear setup so that you have the ability to fix leaks, tears, cracks, and other issues when the need arises.

Flex Tape Versus Regular Glue

Flex Tape has many benefits over using traditional glue or even marine-strength glue for your repairs. Here are a few benefits to consider:

  • It’s easier and cleaner to use
  • It doesn’t require a bunch of cleanup of your hands or the affected surface afterward
  • It works with a wider variety of surfaces and materials
  • It doesn’t contain any harsh chemicals that you’ll find in some glues
  • It can be safely applied with minimal repair experience
  • It’s safe for kids and adults of all ages.

Tips For Using Flex Tape

If you’re going to apply Flex Tape for any reason, here are a few tips to help you get the most out of this product:

  • Use a blow dryer to cure the adhesive and improve the bond when applying Flex Tape to porous surfaces.
  • Maintaining continued firm pressure for several minutes when applying tape will improve the bond. Remember, the bond improves with time and pressure.
  • Don’t try to reposition Flex Tape once it’s bonded.
    • Just cut it away and use a new piece if you must.
  • Select fabrics (i.e. canvas, cotton, polyester, and synthetics) will require a 24-hour period for Flex Tape to achieve its maximum hold.
  • The adhesives may not bond easily with plasticized or waterproof materials, as well as surfaces that are greasy, siliconized, porous, dirty, or oily.
  • Flex Tape may not work for hose repairs.
  • Remember that this is designed to be a temporary fix for emergency purposes. It is not to be used for permanent repairs.
  • In order to remove Flex Tape and clean any remaining adhesive off a surface, you’ll need Flex Tape Adhesive Remover.

Ideally, all Flex Tape products must be stored between 60 and 100 degrees Fahrenheit (about 15 to 38 ℃) and can be applied to surfaces from 20 to 120 degrees Fahrenheit (about -7 to 49 ℃). They will also withstand a maximum temperature range of -40 to 200 degrees Fahrenheit (about -40 to 93 ℃).

How To Use Flex Tape

Regardless of the exact Flex Tape product you choose, the process for applying it remains the same. Here’s a basic breakdown of how to use Flex Tape:

Step One

Leave the backing on the tape as you roll out the desired length. Cut it to the dimensions you need. It’s best to utilize a razor blade, a high-quality knife, or a sharp pair of scissors to get the cleanest cut possible.

Step Two

Clean the surface you intend to stick the tape to before moving forward. It should be free of as much dirt and debris as possible that could interfere with the bond of the adhesive. Then, remove the backing to expose the adhesive.

Step Three

Apply your tape to the problem area and press down firmly. If you are applying the tape to a large area, press down all around the tape to begin the bonding process. Wood is great for applying pressure to the tape backing on more flexible surfaces, such as a pool liner or inflatable whitewater kayak.

Step Four

Remove any air pockets using your fingers, a squeegee, or a plastic roller. Air pockets will decrease the strength of Flex Tape’s bond, so don’t skip this step and be meticulous in completing it.
