## 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
