## Questions & Answers

**Q: Can this be used on flexible surfaces?**
A: Depends on how flexible. It has to be able to adhere to the surface. It cures the same as rubber in a tire. There is some give.

**Q: Seal wet surface**
A: Hello there. That's an excellent question. Flex Paste can be applied to dry or wet surfaces and even underwater. It does not dissolve, creating a watertight seal. Thank you very much for reaching out to us with your question. Please write to us anytime. We're always happy to help. Flex On!

**Q: Flex seal pasta can it be used on curved surfaces?**
A: Yes it can be used on any curved and even upside down surface but if ordering on-line, if you open the can and the edges are turning hard return it ASAP because chances is it's hard on bottom as-well and you don't get your money worth

**Q: Can I use in a in ground swimming pool to repair a crack**
A: Yes, it can be applied underwater. It won’t dissolve or wash away. It even dries underwater! Flex Paste is easy to use. With a putty knife, trowel, spatula, roller, or stiff brush remove a smooth even layer of material from the top of the tub. Scooping deeply into the tub may cause air pockets which can dry FLEX PASTE.  Apply a generous amount using a smooth sweeping motion.
