Meaning and use

4.1 Surface cleaning is used to prepare concrete surfaces for coating for light service.

4.2 This practice is used alone only if the protection system is used for continuous or intermittent immersion, mechanical loading or for protection systems that require good bonding for satisfactory performance (see specifications D4259 and D4260).

ASTM D4258-2017 Standard Practice for Coated Surface Clean Concrete

Radius

1.1 This practice includes surface cleaning of the concrete prior to coating to remove grease, dirt and loose material. Procedures include broom cleaning, vacuum cleaning, jet cleaning, water cleaning, detergent water cleaning and steam cleaning.

1.2 This practice is not intended to alter the surface profile of the concrete, but to clean the surface.

1.3 Values in inch-pounds shall be considered as standard values. No other units of measurement are included in this standard.

1.4 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use. See Section 5 for specific hazard descriptions.

1.5 The international standard is based on internationally recognized standardization principles established in the “Decision on Principles for the Development of International Standards, Guidelines and Recommendations” issued by the Committee on Technical Barriers to Trade (TBT) of the World Trade Organization.
