I used it to cover the tops of dock pilings. I recommend it. ### ⭐⭐⭐⭐⭐ Works as good as on TV *by D***T on May 18, 2026* I used this to seal a leak in my concrete fountain. I was a bit hesitant having only seen it on TV commercials and no one else's experience. I cleaned around the crack, sprayed 2-3 layers over it and refilled. It's been several months and no leak. ### ⭐⭐⭐⭐ For the right job, it's the tool *by R***K on April 29, 2026* Left no room for doubt that this is liquefied rubber in an aerosol. Be careful to get the Right Tool for the job. Check their "store" on Amazon- interesting discoveries there. For waterproofing / moisture barrier I would consider this again if a thin layer is adequate. May need to develop some application "technique" in some instances. My unusual situation involved some gaps that were worse than I anticipated. It's thin. Layering onto partially dry base layers to bulk it up did work but it's tricky until you find the way. I should have had silicone caulk on hand too but this seals hairline gaps nicely. With clear version, it's hard to see what's happening & to avoid waste or a running mess. Clogging is not a problem you'll likely have. As you might expect, liquid rubber involves intense solvents. You cannot over ventilate when using this. Plan ahead if using indoors. ## Frequently Bought Together - Flex Seal, 14 oz, 2-Pack, Brown, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - 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 --- ## 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.be/products/15511873-flex-seal-14-oz-2-pack-brown-stop-leaks-instantly](https://www.desertcart.be/products/15511873-flex-seal-14-oz-2-pack-brown-stop-leaks-instantly) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-01*
