## Questions & Answers

**Q: What temperature requirements for flex seal to work**
A: Flex Seal Spray can be applied to surface temperatures from 0°F to 100°F. Once it has fully cured, it is designed to withstand temperatures from  -20°F to 140°F. Thank you for your interest in the Flex Seal Family of Products.

**Q: Can this spray work on a hairline crack in my basement floor?   And will it be slippery if it gets wet?**
A: Flex Seal Spray is a fantastic product to fill cracks and holes with a liquid that dries into a watertight, durable, flexible coating. Due to its essential sealing qualities, we do not suggest it for underfoot applications because surfaces may become slippery when wet.

**Q: Will it work to plug up a pin hole in a copper water pipe?**
A: Yes, Flex Seal Spray will seal the hole, effectively blocking out water, air, and moisture. However, we do not recommend it for high-pressure applications. Message us with any other questions about our products. We're always happy to assist our customers!

**Q: Can this be used on plastic on car where window washer  goes?**
A: Hi there! Flex Seal Liquid can be used on many surfaces such as concrete, glass, brick, stucco, masonry, wood, copper, plastic, tile, fabrics, wires, vinyl, fiberglass, ceramic, porcelain, metal, aluminum, natural stones, foam, asphalt, EIFS, TPO, PVC, EPDM, CSPE, Hypalon polyurethanes and much more. Please note that results may vary based on the specific type of plastic and application, so we recommend testing a small area if possible.

Always good stuff

### ⭐ HUGE RIP OFF
*by M***G on March 6, 2023*

OMFGosh, what a joke. I think you could probably get a bigger can out of a gumball machine. For $15 I would say I've been taken. I don't think there's maybe $3 worth of spray in this tiny can. NOT MINI......... Super Tiny.
