Foreword

This SSPC/NACE International Joint standard covers the preparation of concrete surfaces before the application of protective coating or lining systems. This standard should be used by specifiers, applicators, inspectors, and others who are responsible for defining a standard degree of cleanliness, strength, profile, and dryness of prepared concrete surfaces.

This standard was originally prepared in 1997 by SSPC/NACE Joint Task Group (TG) F, "Surface Preparation of Concrete." It was reaffirmed in 2003 by SSPC Group Committee C.2, "Surface Preparation,"and NACE Specific Technology Group (STG) 04, "Coatings and Linings, Protective-Surface Preparation." It was revised in 2018 by TG 417 (formerly Task Group F). This standard is issued by SSPC Committee C.7.7, and by NACE under the auspices of STG 04.

In SSPC/NACE standards, the terms shall, must, should, and may are used in accordance with Paragraph 2.2.1.8 of the Agreement between SSPC: The Society for Protective Coatings and NACE International. The terms shall and must are used to state mandatory requirements. The term should is used to state something considered good and is recommended but is not mandatory. The term may is used to state something considered optional.
