When you need to stop a leak, repair broken items around the house, or mend tarps, canvas, or other fabrics, you need strong adhesive products.
Gorilla Waterproof Patch & Seal is a strong, reliable waterproof adhesive that's suitable for a range of real-world applications. It's produced by The Gorilla Glue Company, which also makes a wide range of sealants and adhesives for residential use.
But, as we'll explain below, it has its limitations.
The problem is that when you need to fix things inside or outside the house, you require reliable, long-lasting, specialized adhesives that adhere now and will continue to adhere, even after being exposed to the sun, rain, ice, and cold month after month.
That's why we've put together the following comparison article. We examine several other strong, reliable adhesives, such as Flex Tape, Eternabond and TitanPatch Pro, to determine which one reigns supreme.
Flex Tape: The TV Famous Option
Thanks to this brand's viral marketing tactics, Flex Tape might be the most well-known sealant tape on our list.
If you don't remember the infamous late-night commercials, they involved the brand's spokesperson, Phil Swift, cutting an aluminum boat in half, taping it back together with Flex Tape, and then taking it out for a spin on the water.
That's a pretty cool commercial, honestly! It's definitely a dynamic ad. It's got oomph, pizazz, and zing. But it's also a bit over the top and unrealistic.
We've spent some time trying out Flex Tape. And while it's definitely a strong adhesive, it doesn't last as long as you might think. It's a great product for quick household fixes. However, it's not a suitable long-term repair solution.
Flex Tape claims to be UV-resistant. But when we tried using it outdoors, we found it just didn't stay firm and tacky. The brand also claims its tape can withstand extreme temperatures. Yet they don't list any temperatures or provide guidance on application temperatures.
Eternabond Tape: The RV Roof Specialist
Eternabond is yet another popular sealant that's been around much longer than Flex Tape. It's a tough and durable sealant tape that features a reinforced backing and a UV-resistant adhesive. The tape's double-thick adhesive (compared to standard duct tape) uses the brand's patented MicroSealant Technology that ensures it grips smooth, rough, and uneven surfaces alike.
Due to this, Eternabond sealant tape is widely used and trusted in the RV community for repairing RV roof leaks.
It's a great sealant solution for RVers looking to repair leaky camper or RV seams, vents, and edges. However, it can also be used for a wide range of household applications.
On the downside, Eternabond tape doesn't stick to silicone at all! And to get it to stick to other surfaces, it's recommended you use a can of EternaClean and EternaPrime.
So you're not just buying a roll of sealant tape to complete your repair. You will also need to purchase additional products to ensure Eternabond works properly, which means your repair project may cost slightly more than expected.
And in our experience, even a small leak repair project can quickly get above the $100 mark when you consider having to buy multiple Eternabond products.
TitanPatch Pro: The Industrial-Grade Upgrade
Finally, TitanPatch Pro is yet another great sealant tape designed for heavy-duty and all-weather use.
In fact, we firmly believe TitanPatch Pro is THE strongest sealant tape currently on the market.
We took a thorough look at Gorilla Sealant Tape, Flex Tape, and Eternabond, examining their shortcomings, and designed TitanPatch Pro to be stickier, stronger, and the most reliable sealant tape on planet Earth.
It's a professional-grade sealant designed with military-grade precision, allowing you to tackle almost any type of repair, indoors or outdoors, on RVs, campers, trailers, boats, or even gutters, all without worrying about weather or UV damage.
TitanPatch Pro remains tacky and waterproof in temperatures ranging from -40°F to 190°F, providing a reliable multi-surface adhesive that helps you complete the job and keep it fixed regardless of the conditions.
Below, we break down each of the most popular Gorilla Sealant Tape alternatives to illustrate exactly why we believe TitanPatch Pro is the best option out there.

Comparison Table: Gorilla Sealant Tape Vs. Top Alternatives
Which Gorilla Sealant Tape Alternative Should You Choose?
The best Gorilla Sealant Tape alternative depends on what you're repairing and how long you want the repair to last.
If you're looking for a quick fix, choosing Flex Tape is perfectly fine. It's a far cry stronger and more reliable than duct tape. But it's not suitable for longer-term use, especially not if outdoors.
Eternabond is another good option. It's waterproof and offers good UV-resistance. But it's mainly just used for RV roof repairs. It's also not a standalone product, as the brand recommends using EternaClean and EternaPrime to ensure more reliable adhesion.
That said, if you're looking for a reliable, heavy-duty waterproof solution that can be used indoors, outdoors, and everywhere else, check out TitanPatch Pro for yourself.
It's an all-around better and more versatile sealant tape that adheres to a wide range of surfaces, including wood, brick, stone, stucco, plastic, metal, and virtually any other type, and holds strong for up to 15 years.

Frequently Asked Questions - The Best Gorilla Sealant Tape Alternatives
When tackling the toughest jobs around the house or patching minor leaks, gaps, and cracks on your RV roof, you need strong, durable, and reliable sealants and adhesives.
The Gorilla Tape alternatives we've discussed today are among the best options on the market. But before you choose one, let's review some frequently asked questions we often hear from our readers.
What is stronger than Gorilla Tape?
Gorilla Tape is already strong. However, it won't last long when exposed to UV rays or other outdoor elements. TitanPatch Pro, on the other hand, is designed as a stronger, more durable, and more versatile sealant tape that holds no matter what the weather throws at it.
Can Flex Tape replace Gorilla Tape?
Flex Tape is a better waterproofing solution. However, similar to Gorilla Tape, it's not the most UV-resistant product out there. Suppose you're looking to complete outdoor waterproofing repairs. In that case, we strongly recommend checking out TitanPatch Pro or Eternabond, which offer superior UV resistance and more reliable, long-term waterproof seals.
How long does Eternabond last compared to Gorilla Tape?
When appropriately applied, Eternabond and Gorilla Tape can last for years. Eternabond will likely last longer and outperform Gorilla Tape. However, external factors such as UV exposure, temperature, rain, snow, and ice can all affect the longevity of these products.
Can TitanPatch Pro be used underwater?
No, TitanPatch Pro cannot be used fully submerged underwater. It's a robust and durable waterproof solution, but it's not designed for underwater use. We also recommend cleaning and drying your surfaces before applying our sealant tape to ensure better and longer-lasting adhesion.
Which tape is best for outdoor use and RV roofs?
TitanPatch Pro is the best sealant tape we've seen for both indoor and outdoor usage. Eternabond sealant tape comes close thanks to its UV resistance. But only TitanPatch Pro offers industrial-strength adhesion that's 100% waterproof, UV-resistant, and designed to stay firm and tacky at temperatures ranging from as cold as -40°F to as high as 190°F.
Is there a truly permanent waterproof tape?
Yes! TitanPatch Pro is designed to be the most waterproof and longest-lasting sealant tape available. We built TitanPatch Pro to be stronger, stickier, and more reliable than Flex Tape, Gorilla Tape, and Eternabond combined. It's not just moisture-resistant. It's entirely, honestly, and permanently waterproof, offering you a reliable solution for a wide range of waterproofing projects.
