Samantha - Customer Care at Flex Seal Products (Swift Response The makers of Flex Seal Liquid) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Flex Seal can eliminate periodic outdoor house painting *by on Reviewed in the United States July 28, 2025* This stuff has provided a 'final solution' for certain outside wood on my home. I live where the seasonal temperature range can be 100F to -40F. This is brutal on even the best, long-lasting outdoor house paint. Every few years I would have to scrape and/or sand cracked or peeling spots and do touch up. Since I first used Flex Seal on critical places (like window frame tops where snow and water sit), I have had NO FURTHER MAINTENANCE.Note that there is conflicting information as to whether you can apply regular paint on top of the Flex Seal (for me, I wanted to knock down the Flex Seal's high gloss finish). So, last year, I painted over some trim that had been painted previously with Flex Seal to test adhesion and durability. All I did to prep the Flex Sealed surface before applying regular house paint was to scrub with a TSP solution. So far, no peeling or cracking has occurred.The only negative I have observed is that the Flex Sealed surfaces attract dust noticeably, almost like it's statically charged. However, the surface cleans up easily with a hose and soft-bristled brush.This stuff yields a truly waterproof barrier that has eliminated the periodic painting I had to do every 2-3 years. The wood trim is sealed and no shrinkage or cracking has occurred. I'm getting older, so the less time I spend on a ladder is fine with me! ### ⭐⭐⭐⭐⭐ My son saved $850 using this product and I have solved several problems with Flex Seal Liquid. *by on Reviewed in the United States May 5, 2016* I purchased this for my Son and he is very pleased with the application a durability of Flex Seal Liquid. Instead of spending $1000 on Rhino Lining his truck again, he used Flex Seal Liquid. He rolled his entire truck bed with it. He put 4 coats on his Chevy Silverado with an 8ft bed. He used 1 and 3/4 gallons to complete the job. It is thick and can handle the hard knocks. The look of it is actually more attractive than Rhino Lining. Update: I also used Flex Seal to repair the interior of my Honda Accord. There are plastic parts inside the car that have deteriorated over time from the heat and sun in Florida. The plastic became tacky and was coming off onto everything that touched it. My hands were constantly getting sticky and it actually ruined a few pieces of my clothing. I taped up the areas surrounding that plastic and applied Flex Seal. It became hard over night and and now those parts actually look better now than they did when the car came from the factory. I must add that the quality of the liquid Flex Seal seems to produce much better results than the spray. I've used the spray on a few items around the house and it does not apply as evenly as they liquid and is no where near as durable as the liquid. This product is absolutely fantastic! There is no doubt in my mind that boat cut in half in the commercial was indeed repaired with Flex Seal. It is the real deal! ### ⭐⭐⭐⭐ Very Good *by on Reviewed in the United States November 23, 2025* Very good, clean/dry concrete surface, it adhered and dried very well. ## Frequently Bought Together - Flex Seal Liquid, 1 Gallon, Black, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Flex Seal 2-Pack Black 17oz Stop Leaks Instantly, Waterproof Sealant Coating For Gutters, RV, Roof, Skylights, Windows - Flex Tape, MAX, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor - Home RV Roof and Pool Repairs, Black, 4 in x 25 ft, Pack of 1 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/35069452-flex-seal-liquid-rubber-coating-sealant-waterproof-flexible-breathable-uv](https://www.desertcart.co.th/products/35069452-flex-seal-liquid-rubber-coating-sealant-waterproof-flexible-breathable-uv) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-13*
