3M™ Concrete Repair Self Leveling is a fast-curing polyurethane adhesive designed to repair cracks, spalls and breaks in concrete floors and horizontal concrete surfaces. Self-leveling repair material applies with a common caulk gun and flows freely into horizontal repair areas. It hardens in as little as five minutes and allows for sanding and refinement in 15 minutes, eliminating downtime.

Fast, Long-Lasting and Effective Concrete Repair
Instead of calling a contractor and keeping your floors out of service for 24 hours or longer, our 3M™ Concrete Repair Self Leveling lets you do it yourself in minutes. This low-viscosity urethane concrete repair material comes in a cartridge and applies easily from a regular caulking gun. Its self-leveling formula flows freely into cracks, breaks and spalls in horizontal concrete surfaces such as concrete floors. It hardens in as little as five minutes, and can be driven over with a forklift in 15 minutes without damage. The material cures to any depth without cracking, and can be sanded and refined for smooth finishes. It also expands and contracts to resist cracking or loosening for long-lasting repairs vs. standard concrete.

3M™ Concrete Repair Self Leveling is Ideal for minor repairs in building construction, shop floors, walkways, stairways, pools, decks and patios.
