Fantastic !! ### ⭐ Shame! shame! shame! *by A***R on September 27, 2024* Rating is "0". Product could not be used. It was as hard as a brick. We tried to make a hole toward the bottom to see if it was softer, it was as hard as the top. We tried to spread it on the roof, it would not work. We has to run to Walmart to get new cans to do the job. ## Frequently Bought Together - Flex Paste MAX, 12 lb Can, White, Waterproof Paintable Putty, Spackle Sealant, Fill Gaps Cracks Holes - Block Out Water and Air - UV Resistant - Walls, Drywall, EPDM, Concrete, Roof, RV Repairs - Flex Tape, MAX, 4 in x 25 ft, Clear, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects - Home RV Roof Plumbing and Pool Repairs - Flex Tape, MAX, 4 in x 25 ft, White, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects - Home RV Roof Plumbing and Pool Repairs --- ## 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.tn/products/312007933-max-12-lb-can-white-waterproof-paintable-putty-spackle-sealant](https://www.desertcart.tn/products/312007933-max-12-lb-can-white-waterproof-paintable-putty-spackle-sealant) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-22*
