This standard includes procedures for using pressurized water to remove loosely adhered surface contaminants. It contains requirements for the cleaning process, for the end condition of a lightly cleaned concrete surface, and for verification of the end condition. The standard does not address removal of water-insoluble contamination; assessment of concrete soundness and pH; repair of the substrate and exposed reinforcing steel; or required surface profile (see Paragraphs A1, A2, and A3 of Appendix A [nonmandatory]). Light cleaning by pressurized water will not create a concrete surface profile, it will only expose existing profile. SSPC-SP 13/NACE No. 6 contains additional information on these topics.
