It has a backing on it that you pull off before you stick it down. You could cut it before you take the backing off. But make sure you do it before, since it is really sticky once the backing is off. ## Frequently Bought Together - Flex Tape, MAX, 4 in x 25 ft, Black, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects - Home RV Roof Plumbing and Pool Repairs - Flex Tape Black - 8 in x 25 ft - Flex Seal, 14 oz, Black, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More --- ## 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.ec/products/298736962-flex-tape-max-original-thick-flexible-rubberized-waterproof-tape-seal](https://www.desertcart.ec/products/298736962-flex-tape-max-original-thick-flexible-rubberized-waterproof-tape-seal) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-10*
