Review: Do not use before confession! - This stuff is so sticky it's dangerous. I am quite statistically challenged when it comes to pulling something off well so I've wasted a lot. Advice is to keep it in small pieces that are ready to go right where you want. Once you disconnect it, tear the non-sticky part off well right there if you've ever done something bad and unconsciously you know that it can be ugly you might just smash it right into the middle of your face! I do not even a little believe the commercial with the boat being held together by the stuff, I find putting it on wet surfaces to be more of the put a piece of paper on a wet surface experience still, I carry around for rolls cause it's good for making up whichever headlight or tail light you smash off, nice fits there. It'll fill up cracks (oh heck, maybe that's why she divorced me?"
Review: Would purchase again - Heavy duty and sticks good

## Questions & Answers

**Q: Will it work on my lanai screen?**
A: Yes. Since the screen is a porous material, we would recommend applying Flex Tape to both sides of the hole or tear thus creating an incredibly strong bond. For best results, start with a clean surface free of grease, oil and dirt. Apply firm pressure smoothing out all air bubbles. Once applied, Flex Tape provides a strong yet flexible waterproof bond that, unlike most tapes on the market, increases overtime. Thank you for your interest in the Flex Seal Family of Products.

**Q: Will it work on resin outdoor furniture**
A: There are certain plasticized materials that contain olefins that by their very nature constantly release chemicals that ultimately resist proper adhesion.  It is my understanding that resin furniture is usually made of a particular plastic called high-density polyethylene which contains olefins. Therefore, it may not adhere properly. It may still perform but I would test a small area first.  For best results, start with a clean surface free of grease, oil, dirt and algae. Apply with firm pressure smoothing out all air bubbles.

**Q: can I use flextape to patch a  big tear in the canopy swing seat ?  Would it hold the weight of someone sitting there?**
A: The larger the tear the bigger the issue maybe if someone can sit on it without tearing it further. When applying the Flex Tape we recommend applying it on both sides of the tear. One on top and one on the bottom to ensure a stronger bond and give you more protection from the tear.

**Q: Can it be used to wrap sharkbite plumbing connectors for underground use?**
A: I used it on my pool wall and liner under water for the liner and it solved the leak it’s amazing

Heavy duty and sticks good

### ⭐⭐⭐⭐ Not a fix all but fix most
*by B***L on March 25, 2025*

It's not a fix all but roughly will handle 90% of what you can think of using it on. Big poly tanks even applied on the inside will not hold. Too much pressure. Otherwise small simple leaks, it works great
