## Questions & Answers

**Q: Is it paintable ?**
A: Yes, once dry Flex Seal Spray can be painted. Reach out to us if you have any other questions. We're always glad to assist. Flex On! 🎨

**Q: Is this safe to use inside of pots with plants ? I have rare specimen tropicals that are hardy but I don't want chemicals seeping into the soil. Thx**
A: Only Flex Seal Liquid is safe around plants and animals (once fully cured).

**Q: I have a very large clay pot with a crack in it and am afraid it’s only going to get worse. Can Flex Seal prevent that from happening?**
A: I don't know if it will prevent the crack from getting bigger in the short run, but my experience with Flex Seal spray sealant coating is that it doesn't last in San Diego sun for more than a couple of months.

**Q: Which kind should I use for ceramic pots**
A: Hi there! Flex Seal Spray is available in a variety of colors and will adhere to most surfaces such as: wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, porcelain, drywall, rubber, cement, some vinyl and more. We recommend testing on a small area before the complete application and making sure the surface is dry and clean of any dirt, oil, and grease. Flex Seal Liquid would be a great possible alternative for ceramics, though please note it can only be top coated with more Flex Seal Liquid. Message us directly with more details on your project so we can find the best solution for you. Until then, take care and Flex On!
