ASTM D4261-83(1999)

Standard Practice for Surface Cleaning Concrete Unit Masonry for Coating

SCOPE
1.1 This practice covers surface cleaning of concrete unit masonry to remove dust, dirt, mortar spatter, oil, and grease prior to the application of coatings. Procedures include vacuum cleaning, air-blast cleaning, water cleaning, detergent water wash, steam cleaning, and mechanical cleaning.  
1.2 This practice is not intended to alter the surface profile of the concrete masonry units but to clean the surface.  
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5.
