Introduction

Flex Tape and Gorilla Tape are both designed to be water-resistant and withstand harsh environmental conditions. Whether it’s carrying out temporary repairs, fixing broken items, hanging Christmas trees, or repairing leaking objects; the two are among the very first options that buyers go for when shopping for tapes.

Both vary just slightly in price and quality. While they are designed to perform similar functions, you may find that one works slightly better than the other depending on the type of damage protection or repair job you need. Below is a description of the two, together with their strengths and weaknesses.

Flex Tape

Flex Tape is designed to stick on wet surfaces, hold its grip underwater, and be flexible enough to take the shape of the item it sticks on. It’s rubberized to ensure that it keeps enough air and water away. It features a triple-layered adhesive that can bond, patch, repair, and seal almost anything.

Flex Tape can be used to fix damages and leakages on items made of PVC, metal, ceramic, rubber, stucco, stone, acrylic, wood, glass, fiberglass, drywall, and plaster. While the tape is built for a wide array of applications, the company behind it notes that it may not work well with plasticized, siliconized, oily, dirty, or greasy surfaces.

The tape is available in 3 different rolls – 4”× 5’ ($19.99), 8” × 5’ ($29.99), and 12” × 10’ ($49.99). It’s important to note that it’s only intended for temporary repairs and emergencies.

Strong Sides

• Strong and doesn’t tear or cut easily.
• Can withstand chilly environments and seasons.
• Great for gutters and roofing material.

Weak Sides

• Can’t be used as a long-term solution.
• Loses grip at temperatures above 200o F.
• Can’t be used where there’s high pressure.
• Super-sticky and needs care while in use.

Gorilla Tape

Gorilla Tape has a strong and highly sticky adhesive that allows it to seal all types of leaks and cracks. Its water-proofing ability makes it a good option for outdoor repairs. It measures 1.88 × 9 inches and occupies a considerable surface area wherever it’s applied.

The tape itself is double-layered while the adhesive is double-layered to provide enough thickness and toughness for high-pressure cracks and leaks. Some of the materials supported include brick, stone, plaster, and wood. Gorilla tape is available either as crystal clear tape or heavy-duty black tape. It’s also UV-resistant to prevent any damage that may be caused by extreme temperatures. Prices start from $8.47 upwards depending on where the tape is bought.

Strong Sides

• Flexible and sticks firmly.
• Can be easily torn by hand.
• Extremely tough due to its multiple layers.

Weak Sides

• Leaves behind adhesive residue when used for long.
• Turns yellow if exposed to extreme temperatures for too long.
• Not very effective on plastics and PVCs.

Overview and Conclusion

Both tapes perform almost similar when it comes to handling repairs and leaking surfaces. Thanks to its thickness, Gorilla Tape gains a slight edge over Flex Tape. It’s tougher, stronger, and more durable.
