Additional Information

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.

This product is excellent if you follow the directions. When they say, "stir" they mean it. You have to stir the product until the liquid is consistent all the way from top to bottom. And then stir a little more. If you don't the liquid on top will be runny and thus will not do what you want it to do. I just covered a birdbath after stirring the product for 10 minutes and it went on like a dream. Use a piece of wood or other item to stir the Flex Seal until it is completely even throughout. You'll be amazed at the results. Remember....stir. The liquid on the brush is easily cleaned with mineral spirits.
This did what I expected. I have a 1976 Volkswagen Beetle convert. that I am fixing up. The rubber on the running boards was dried out and
discolored, along with some splits in the rubber showing bare metal underneath. It was going to cost well over two hundred dollars each to replace them, so I thought I'd try Flex Seal. After cleaning and drying the running boards I applied the product with a small paintbrush. It went on easily,covered really well, and small "oops" we're easily wiped up with a cleaning cloth. I allowed a drying time of 24 hours and just now went out and filled in the split areas with a little more product and smoothed it out with the brush. It looks fantastic! I took a couple pictures which don't do it justice. It dried really shiny, and looks wet although it's dry and looks and feels like rubber.
Some tips: I first stirred it very well because I could tell it was thick at the bottom of the can. It was easy to stir up though. When I was... Read more
