MAN-MACH's Concrete Washing Machine is designed to clean concrete surfaces of slurry, oil, dust and other contaminants. Using high pressure water jetting or chemical cleaning techniques, the concrete cleaning machine quickly and efficiently removes contaminants from the concrete surface, revealing a clean and rough substrate. This treatment can significantly improve the adhesion of subsequent coatings, adhesives and other materials with the concrete surface, effectively protect the durability of concrete structures and decorative effect, widely used in building maintenance, renovation and painting projects.
