Description

NACE AMPP SP21548 – Pressurized Water Cleaning of Concrete and Cementitious Materials – Thorough Cleaning

This standard includes procedures for using pressurized water to open surface voids and remove visible surface contaminants and existing coatings from concrete surfaces. It contains requirements for the cleaning process, for the end condition of a thoroughly 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]). SSPC-SP 13/NACE No. 6 contains additional information on these topics.
