Product details
Flex Seal Liquid is liquid rubber, in a can! Unlike traditional paints, Flex Seal Liquid starts out as a thick liquid, that can seep into cracks and holes to form a flexible, waterproof, weatherproof rubberized seal. Easy to use, you can brush on, roll, dip or pour to stop leaks fast. Flex Seal Liquid can be used for a variety of coating and sealant applications. Use anywhere you need a watertight, flexible rubberized coating. Flex Seal Liquid goes on smooth and covers fast, sealing out water, air and moisture. Flex Seal Liquid seals and protects surfaces from the elements, and extreme temperatures. Flex Seal Liquid is perfect to use all around the house, from roofs and gutters down to floors and basements. Flex Seal Liquid Available in clear, gray, black & white.
Common Flex Seal Liquid Applications:

AMAZING
I bought this to seal a leaky bay window that went down to the floor. I only used one coat and worked beautifully. The only negative I'd say about it, is the price. I bought the pint and thought it was a little pricey but otherwise it probably wouldn't keep me from buying it again. It just worked so well.

BASEMENT WALL LEAK
WE HAVE HAD A LEAK IN THE BASEMENT WALL, WHERE THE WELL PUMP PIPING AND WIRING CAME THROUGH THE WALL, FOR OVER 20 YEARS. I HAVE TRIED A VARIETY OF REMEDIES TO FIX THE LEAK OVER THE YEARS AND ALL HAVE FAILED. I SAW A COMMERCIAL FOR 'FLEX SEAL' AND ORDERED 2-16 OUNCE CONTAINERS OF 'FLEX SEAL LQD WHITE'. FOLLOWING THE CAN DIRECTIONS FOR WALL PREP I PAINTED A COATING OF 'FLEX SEAL', AROUND THE PIPE AND THE WIRES COMING THROUGH THE WALL. LET DRY FOR 48 HOURS AND PAINTED A SECOND COAT. SINCE THEN WE HAVE HAD TWO HEAVY RAINS WHICH WOULD HAVE CAUSED LEAKS AROUND THE PIPE AND WIRES AND THE 'FLEX SEAL' HAS STOPPED THE LEAK COMPLETELY. I STILL HAVE A CAN AND A HALF LEFT FOR OTHER PROJECTS.

Great Product
I used this product on the inside of weightlifting collars to give them a slightly smaller diameter and a little more grip on the bar. It worked great although it is just a little bit thin to brush onto sloped surfaces. It tends to sag, droop, run etc. mostly by it's own weight I'm sure. that said I am so impressed that this is liquid rubber that drys tough and is actually white! I have some window problem and I plan to brush Flex Seal on the really bad spots to keep water out while I search for a fix. It would make a great sound deadening or sealing layer between surfaces etc. This is a dream come true.
