QUIKRETE's Advanced Polymer Crack Sealant is the fastest permanent solution for hairline to 1/4-inch cracks in concrete foundations, driveways, sidewalks, and basement floors. The advanced acrylic polymer formula flows into the crack under its own weight, creating a flexible bond that is stronger than the surrounding concrete once cured. It resists water infiltration, freeze-thaw damage, and oil staining. Unlike rigid epoxy fillers that re-crack as concrete shifts, this formula accommodates minor movement without failure. A single cartridge covers approximately 20 linear feet of standard hairline cracks. The self-leveling formula on horizontal surfaces requires no tooling — it levels itself smooth. QUIKRETE is the most trusted name in residential concrete repair.
