We highly advise creating the coating by adding layers to the surface rather than just one thick coat. **Q: Any temperature requirement?** A: Flex Paste can be applied in a wide range of temperatures from 0°F – 150ۜ°F. Once applied and fully cured it can withstand a wider range of temperatures from -40°F – 200°F. **Q: Can this be used to fix crack in small ref/frezer** A: Hi there. Thank you so much for reaching out. Flex Paste can withstand low temps like that in a freezer. Although some customers have found success with similar applications, it has not been tested for its safety when coming in contact with items used for food preparation, storing, or serving. Please contact us if you have any additional questions. We're always happy to help. Flex On! **Q: can flex paste be painted ?** A: Yes. Must be fully cured before painting. ## Frequently Bought Together - Flex Paste, Waterproof Paintable Putty, Spackle Sealant, Fill Gaps Cracks Holes - Block Out Water and Air - UV Resistant - Walls, Drywall, EPDM, Concrete, Roof, RV Repairs, White, Quart - Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, White, 9 oz, 1-Pack - Flex Seal Liquid, 1 Gallon, White, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/208933842-flex-paste-rubberized-waterproof-sealant-paste-white-quart-1-pack](https://www.desertcart.sn/products/208933842-flex-paste-rubberized-waterproof-sealant-paste-white-quart-1-pack) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-28*
