Which made the whole fixture crack at the water expanded. I use this flex paint to see if it would be able to seal the cracks and hold the water and it did!!! No more leaks and i the adhesion holds really really well. Drives fairly quickly like maybe 24 hours. The smell is a little strong so I would let it sit outside as it dries. ## 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, Half-Quart - Flex Seal, 14 oz, Clear, Stop Leaks Instantly, Transparent Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/339169069-flex-seal-paste-1-lb-jar-white](https://www.desertcart.com.sa/products/339169069-flex-seal-paste-1-lb-jar-white) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-09*
