Let see which standard say what about the surface preparation:

Comparison between the different standards: Surface preparation as per American, Swedish and Japanese regarding the co-relation between, for example CSP-10, SP10, SA.2.5 and Sd2 - Sh3, etc.

Reference the following industry standards for preparation of concrete from the ASTM International (formerly known as American Society for Testing and Materials-ASTM), NACE International (formerly National Association of Corrosion Engineers), Society for Protective Coatings (SSPC), and the International Concrete Repair Institute (ICRI): ASTM D4258, Standard Practice for Surface Cleaning Concrete for Coating ASTM D4259, Standard Practice for Abrading Concrete ASTM D4260, Standard Practice for Liquid and Gelled Acid Etching of Concrete ASTM D4261, Standard Practice for Surface Cleaning Concrete Unit Masonry for Coating ASTM D7682, Standard Test Method for Replication and Measurement of Concrete Surface Profiles Using Replica Putty SSPC-SP13/NACE 6, Surface Preparation of Concrete ICRI Standard 310.2 Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays, and Concrete Repair with CSP Chips.

Let us see a video to understand this very clearly:
