Flex-A-Fill 9075R Hot Asphalt Crack Sealant is a stable elastomeric developed specifically for the purpose of sealing cracks in asphalt and concrete surfaces such as driveways, parking lots or streets.

Flex-A-Fill hot asphalt crack sealant is a compound with exceptional bonding qualities, high resilience, and incredible flexibility to accommodate large joint movement through extreme temperature cycles. In fact, Flex-A-Fill sealant will remain pliable and track free at temperatures ranging from -20°F to +130°F.

When cracks in asphalt and concrete remain untreated, sun, wind, rain, cold and traffic can widen cracks at an alarming rate. Ultimately, unfilled cracks will cause total pavement failure. A single application of easy-to-use Flex-A-Fill hot asphalt crack sealant lasts many times the life of ordinary asphalt fillers, and is guaranteed to be the most trouble free crack sealant you have ever used.

This product comes as a single 30 lb solid block of rubber that is ready to drop into a melter after the protective cardboard box has been discarded.

Application of Flex-A-Fill crack sealant is convenient and inexpensive whether you choose to use one of our Asphalt Crack Melters, or your own equipment. Flex-A-Fill hot crack sealant can be heated and poured at a relatively low temperature. Its low viscosity allows it to penetrate the smallest of cracks without the extra expense of routing the asphalt.

Flex-A-Fill hot asphalt crack sealant has a variety of uses ranging from driveways to parking lots, from tennis courts to highways, and even airport runways. It can seal asphalt to concrete, asphalt to asphalt, and concrete to concrete. Flex-A-Fill sealant has been used to seal cracks in swimming pools, pipes, and to waterproof roofs. Whether the application is commercial or residential, Flex-A-Fill crack sealant can do the job and do it right the first time.

Flex-A-Fill Crack Sealant expands and contracts with joint movement to maintain a perfect seal. Its bonding qualities and flexibility are truly remarkable. Tracking is virtually never a problem with Flex-A-Fill sealant. Its rapid set-up time (20-30 minutes) allows immediate traffic. It also does not require sanding which makes it an invaluable commodity in most warm weather areas. Since Flex-A-Fill sealant resists bleeding through, it is regarded as the premium material for use prior to seal-coating, slurry seals, chip seals, and other asphalt overlays. Its applications are virtually limitless.
