The ASTM D4258-23 standard provides a method of surface cleaning of concrete with the aim of removing grease, dirt and loose materials before coating. The method includes procedures such as broom cleaning, vacuum cleaning, jet cleaning, water cleaning, detergent water cleaning and steam cleaning without altering the surface profile of the concrete. The standard is applicable to coating systems that require light service to ensure that the surface is clean for satisfactory coating adhesion. Users need to judge for themselves and follow the relevant safety regulations.
