Review: very difficult to pull off if placement is off - covers and conceals like KILZ PRIMER. It adheres like super glue
Review: Holds water in my bathtub! Get to delay rehabbing! Yay!! - It works really great! My fiberglass bathtub was not installed properly and cracked… I tried epoxy repair kits and even called out three contractors to quote repairing my tub… All the contractors pricing included replacing the tub and all the tile surrounding it. The cheapest quote was $7000… I bought this stuff, slapped it on the crack after a good cleaning and drying and I have no hesitation taking baths and I’m not getting any leaks in the ceiling below… I’m saving my bath rehab money for the future when I can do a better job! It saved me a lot of money and although it doesn’t look great it’s not visible when you walk in the bathroom as it’s on the interior wall that faces away from the room…

## 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

### ⭐⭐⭐⭐ Great product but don’t believe what you see on tv
*by S***Y on September 2, 2025*

I purchased flex tape for a few different problems I had. The first was a leak in my water storage tank. The other was a crack in a pond. What I liked: ✅ Quality: very strong and sturdy material will definitely hold up over time. ✅ Seal: when used on a completely dry surface and smoothed out creates a water tight seal. Almost impossible to get off. What I didn’t like ❌ not as seen on tv: this product is shown to be able to apply on an active leak and still seal. You won’t get a perfect seal this way and have small leaks. Only apply to fully dry areas. Same goes for clean smooth surfaces. ❌ heat and weight weaken: if this is used where heat builds up and any sort of weight is applied at the same time it will loosen the adhesive. Overall I do like the product to patch things up but don’t use it like you see on tv. Fully clean and dry the area first. If applying to a surface with texture know that water can travel in the small crevices and still leak out.
