ASTM D4258-05 (R2017) PDF Download

ASTM D4258-05 (R2017) is a standard practice that outlines the procedure for surface cleaning concrete in preparation for coating applications. The purpose of surface cleaning is to remove grease, dirt, and loose materials from the concrete surface to ensure optimal bonding and adhesion of the coating.

The standard provides various methods for surface cleaning, including broom cleaning, vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning. These methods are used depending on the specific requirements of the coating and the nature of the surface contaminants to be removed.

It is important to note that this practice is specifically intended for light-duty service coatings and is not suitable for situations where protective systems will be subjected to continuous or intermittent immersion, mechanical loading, or require optimum bond for satisfactory performance. In such cases, other ASTM practices, such as D4259 and D4260, should be followed.
