Gorilla, Duct or Flex Tape – Which Is Best Underwater?
When you’re trying to find tape for use in watersports and on watercraft it can be difficult to know which one to choose. You need it to be resistant to water and tough enough to stand up to more complex conditions.
There are several brands of tape that claim to be ideal for the job but which one is best? We’ve looked into the different types to analyse flex tape, duct tape and Gorilla tape to find out what they are and what they’re good for.
Quick Answer: Gorilla tape (although there are dependencies - Read on for more)
What Is Duct Tape?
Duct tape (sometimes called Duck tape because of the Duck Brand) is a durable tape that was originally designed to seal ammunition cases for the military during World War II. Because of its versatility and ease of use, it can be found in most homes across the country.
Often silver or black in color, duct tape can be easily torn off its roll, so you don’t need scissors to cut it, and it has a water resistant top layer.
What Is Gorilla Tape?
Gorilla tape is a brand of duct tape that is designed with a double strength adhesive and a reinforced water resistant backing. It is also built to stick to a wide range of materials, including wood, brick and stone - that you’ll probably find other types of tapes may not always stick to.
Similar to regular duct tape, Gorilla tape can be torn instead of requiring to be cut with scissors. It is also UV resistant and can withstand extreme temperatures.
What Is Flex Tape?
Flex tape is a rubberized tape that is designed to be flexible enough to stick to all sorts of shapes. It claims to be waterproof and have the ability to stick to wet surfaces, even holding its grip underwater.
It’s designed to seal out air and water, sticking to many types of surfaces. However, it’s not recommended for use on plastics and for certain other materials, it may not stick right away - requiring at least 24 hours to take hold.
Gorilla vs Duct vs Flex Tape: Which Is Most Waterproof And Best For Underwater Usage?
While all of these products are designed to be resistant to water, you may find that one works better than the others, depending on the type of repair job or damage protection it’s for.
Duct tape can be a handy product to have with you in the event of any emergency repairs .
But Gorilla tape may be better for underwater use.
Gorilla tape can have the durability for acting as a keel guard on the hull of your kayak, giving it that extra level of protection if you’re dragging it along the ground. Because of its extra strength adhesive it can stay put in wet conditions, possibly even when the surface may not be completely dry to begin with.

One thing that may impact your decision is that when Gorilla tape is removed after a long period of time, it can leave behind some residue from the adhesive. This may be difficult to remove but acetone can be helpful in getting rid of it.
Flex tape, while claiming to be waterproof and flexible, states on its packaging that it won’t stick to certain plastics or water repellent/waterproof materials. So this may not be the best choice for plastic based vessels.
How To Apply Tape To Your Boat
In order to make sure your tape sticks to your vessel, it can be a good idea to clean it so that it’s free of any oils or dirt, as this can affect how the tape will stick. It can also be beneficial to make sure the area is dry before you apply the tape.
Sticking with Gorilla tape (no pun intended), apply the tape carefully, making sure there are no air bubbles or creases as you stick it down. You can use a tool to help you, such as a spoon or credit card, just to press out any air that might get stuck between your vessel and the tape.
