NACE NO. 6/SSPC-SP 13-2018 PDF Download

The NACE NO. 6/SSPC-SP 13-2018 surface preparation standard for concrete is a joint effort between NACE International and SSPC (Society for Protective Coatings). It provides guidelines for preparing concrete surfaces before the application of protective coating or lining systems. The standard includes two updated tables that specify different classes of surface preparation and provide minimum acceptance criteria for concrete surfaces before coatings are applied, along with relevant test methods.

In addition to the updated tables, the standard also includes an appendix that contains two additional tables. The first table in the appendix, Table A1, provides information on the typical surface properties of finished concrete. The second table, Table A2, is an extensive list of surface preparation methods specifically for concrete surfaces.

This standard is intended to be used by specifiers, applicators, inspectors, and others who have a responsibility for defining the required level of cleanliness, strength, profile, and dryness of prepared concrete surfaces. It serves as a comprehensive resource for ensuring the proper preparation of concrete surfaces before the application of protective coatings or linings.
