The MMA polymer thin layer rapid repair system can block carbon dioxide, salt, acid rain, etc., and effectively protect the concrete structure. This material has super strong compressive resistance and super strong adhesion, and can achieve ultra-fast and ultra-thin layer repair. It will not break or fall off when driving at airports, highways and high-pressure and under long-term wear and tear.
