What is Concrete Crack Sealer?
Concrete crack sealer is a specialized material designed to fill and seal cracks in concrete surfaces, preventing further damage and deterioration. It is commonly used in driveways, sidewalks, patios, and other concrete structures to enhance their longevity and maintain their structural integrity. The sealer typically comes in liquid or caulk form and is applied directly into the cracks, where it hardens to form a durable, weather-resistant barrier. This process helps to prevent water infiltration, freeze-thaw damage, and the penetration of harmful substances, thereby extending the life of the concrete.
For use in repair or remedial applications where other joint sealing materials have failed because of excessive movement or poor weatherability. Concrete Crack Sealer can be used to seal irregularly shaped and/or spalled joints. It offers outstanding weathering resistance, remains flexible down to temperatures lower than -20°F (-29°C), is jet-blast resistant and will maintain field serviceability when exposed to intermittent fuel and oil spills. It bonds strongly to concrete joints or asphalt without the use of a primer.
Concrete crack sealer can be used in all typical concrete joint/seam or crack applications in most climates and is compatible with asphalt pavement.
Flex Crete™ is easily applied to concrete joints using manual methods or bulk dispensing system units such as those available from manufacturers including Pyles/Graco and Johnstone and/or an inexpensive double-diaphragm pump with a “surge bottle” like Shot™ Pump. The leveling characteristics insure that the required joint wetting for development of appropriate adhesion occurs during application, no tooling is required
