Rapid Set® MORTAR MIX PLUS (MMP) – High-Performance Masonry and Concrete Repair Compound

Rapid Set® MORTAR MIX PLUS (MMP) is a high-performance, rapid-hardening, polymer-modified repair compound engineered for superior masonry and concrete restoration. Designed for fast strength gain, high durability, and low shrinkage, MMP delivers reliable performance in both dry and wet environments.

This advanced formula blends Rapid Set hydraulic cement, quality aggregates, and proprietary additives to achieve excellent workability and consistency. Its polymer modification enhances adhesion and flexibility, while an integral corrosion inhibitor provides added protection for embedded reinforcement. Formulated to match the gray color of standard portland cement concrete, MMP ensures a seamless, long-lasting finish in all repair applications.
