Significance and Use
Surface cleaning is to be used to prepare concrete unit masonry surfaces for applying coatings intended for light duty service, splash and spillage of water and chemical solutions, radiation exposure, decontamination, and repeated washdowns with alkaline cleaners.
1.1 This practice covers surface cleaning of concrete masonry units 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 may alter the surface profile of the concrete but is primarily intended to clean the surface.
1.3 This standard does not purport to address all of the safety concerns, 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.
