Took 4 1/2 hours to remove it from 2 French doors and 1 sliding glass door. The entry door is mahogany and the lower half must be restained. In addition- perhaps due to high humidity- the product becomes thick like sludge and the product isn’t useable when the can is still 1/2 full. Did it or the Flex Seal Tape work, you wonder? The storm surge never happened and saying we are grateful for this is an understatement, as we did flood from hurricane Ian and learned about the Tape after the fact. Next hurricane we will use more Tape and keep our fingers crossed. ## Frequently Bought Together - Flex Seal Liquid Flood Protection, 28 oz, Waterproof Rubberized Liquid, Removable, Use on Windows, Doors, Garage Doors, Seams, Casings, Thresholds, Conduits, Vents, Ducts, and More - Flex Tape Flood Protection, 3.75 in x 50 ft, MAX, Waterproof Rubberized Tape, Removable, Use on Windows, Doors, Garage Doors, Casings, Thresholds, Conduits, Vents, Ducts - Flex Paste Flood Protection, 9 oz Cartridge, 1-Pack, Waterproof Rubberized Paste, Removable, Use on Windows, Doors, Garage Doors, Seams, Casings, Thresholds, Conduits, Vents, Ducts, 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.gr/products/555155594-flex-seal-liquid-flood-protection-28-oz-waterproof-rubberized-liquid](https://www.desertcart.gr/products/555155594-flex-seal-liquid-flood-protection-28-oz-waterproof-rubberized-liquid) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-22*
