Flex Seal Flex Seal Editorial Review
Flex Paste seems to be a reliable and effective solution for repairing cracks and leaks in various surfaces. Customers have reported success in using it on showers, tubs, and even in underwater situations. The paste is described as thick and rubberized, starting off as a paste and drying into a strong and flexible rubber coating. It has been praised for its ease of use and long-lasting results. One customer mentioned that they had been dealing with a leak in their 20-year-old fiberglass/gelcoat shower/tub and had tried other repair kits in the past, but the leaks would eventually reappear. However, after using Flex Paste, they have been leak-free for a couple of weeks and find the repair to be solid. Another customer mentioned that Flex Paste prevented them from having to undergo a costly remodeling project. The versatility of Flex Paste is also highlighted, as it can be used on wet or dry surfaces and is suitable for indoor and outdoor projects. It does not shrink or wash away after application and can be painted any color. The product is described as a super thick rubber paste that coats, seals, protects surfaces, and stops leaks fast. However, one user cautioned against using Flex Paste in a Koi fish pond, as it leaves an oily film on the water surface that is difficult to remove without fully draining and washing the pond. Overall, Flex Paste appears to be a reliable and effective solution for sealing cracks and stopping leaks in various surfaces. Its ease of use, versatility, and long-lasting results have garnered positive reviews from customers.
