Ideal for sealing leaks and protecting a wide range of surfaces, it offers durable weatherproof protection with easy brush, roll, dip, or pour application. Trusted by thousands with a 4.5-star rating, it’s the go-to solution for professional-grade repairs and maintenance. ## Description FLEX SEAL LIQUID is a patent pending, proprietary formulation that starts out as a thick liquid and dries to a super strong, flexible, watertight rubberized coating. FLEX SEAL LIQUID can be brushed, rolled, dipped or poured to create a high performance protective rubber barrier that blocks out air, water and moisture on a variety of surfaces and objects. Once cured, FLEX SEAL LIQUID forms a durable, breathable, weatherproof, non slip barrier that's resistant to rain, snow, sun, wind, hail, air, moisture, UV degradation, extreme temperatures and natural weathering. DIRECTIONS: Stir can well, do not shake. Make sure the surface is clean, dry and doesn't have grease, oil and dirt on it. For better adhesion, scuff surface with sand paper or steel wool. Coverage will vary depending on amounts of coats used. 1 Large 16 ounce - approx. 20Sq. Ft., 1 Jumbo 32 ounce - approx. 40Sq. Ft., 1 Gallon can - approx. 150Sq. Ft., Brush or roll FLEX SEAL LIQUID using an even sweeping motion. Apply several even coats until the surface has been completely covered and ALL cracks and holes have been filled. Allow FLEX SEAL LIQUID to dry 24 to 48 hours and apply additional coats as needed. Always brush or roll over a larger area than just where the leak occurred. Dip object directly into the FLEX SEAL LIQUID make a slight swirling motion. Once the surface has been coated, remove and let any excess drip back into the can. Hang or clip the object in the same vertical position as it came out of the can and let dry. Pour FLEX SEAL LIQUID directly on the surface allowing gravity to take FLEX SEAL LIQUID into cracks, holes and hard to reach areas. Continue to pour until the surface has been covered and all cracks and holes have been completely filled.

Easy to use coverage is exact 18.75 square ft. I painted decking boards 60"x 5.5" will cover total of "8". I recommend using a brush that can be thrown away. I used a 2" all purpose polyester brush $2.99. Depending on how long project takes you might need a spare brush the paint does stiffen quickly. Cannot leave brush to come back later. Do project within an hour. If not brush will not be flexible or pliable. ( have a spare brush). I have cleaned a brush but it was very difficult to get all of the the product out of brush. The foam disposable brushes DO NOT WORK WELL! To do one quarter of a board resulted in using 2 foam brushes leaving a third heavy and crumbled. The foam becomes heavy and comes off the stick. Creating a huge mess. I have also used a small portion of can and if you make sure rim is clean clear of paint and put lid on with a hammer to assure it is closed I have gone back 6 months later and paint was useable not hard no problems ease of use as if just purchased. I've used before I actually used wrong wood and after 4 months the previous wood that I painted was great no mold no rotting. The product held up well exactly as advertised. I have applied and temp dropped to 45 degrees no problem. The picture shows proper wood. Painting front and back to avoid replacing wood again. The value of not having to replace wood especially when it will be touching ground on my ramp. Time and money a huge money saver! Hope this helps. ## Frequently Bought Together - Flex Seal Liquid, 16 oz, Clear, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Pro Grade Paint Brush Set - 3-Pack - 2" Angle Brushes for All Latex and Oil Paints & Stains - Home Improvement - Interior & Exterior Use --- ## 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.com.kw/products/274682576-rubber-coating-sealant-waterproof-flexible-breathable-and-uv-resistant-roof](https://www.desertcart.com.kw/products/274682576-rubber-coating-sealant-waterproof-flexible-breathable-and-uv-resistant-roof) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-20*
