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.
Recommended Applications
- For concrete floors or horizontal concrete surfaces
- Repairing cracks and spalls
- Setting anchors
- Light-duty custom threading and anchoring
- Bonding dissimilar materials (concrete, metal, stone, masonry)
Easy to Apply
3M™ Concrete Repair Self Leveling is a two-component repair material in a convenient cartridge which fits standard caulking gun applicators. The cartridge nozzle (included) meters and mixes precise proportions of material for optimal leveling, hardening and long-term use. The gray material can be sanded in 15 minutes and is paintable in one hour.
