Scope

1.1 This guide is intended as an information aid to painting inspectors in carrying out the task efficiently. It includes the key elements of surface preparation, coatings application, and final approval for both field and shop work. The items should be selected that are pertinent to a specific project. NOTE 1—For additional helpful information, refer to the following documents: Manual of Concrete Practice ACI 515R American Concrete Institute2 Manual of Coating Work for Light Water Nuclear Power Plant Primary Containment and Other Safety Related Facilities3 C811 Practice for Surface Preparation of Concrete for Application of Chemical-Resistant Resin Monolithic Surfacings4 Steel Structures Painting Manual Vol. 1 Good Painting Practices5 Steel Structures Painting Manual Vol. 2 Systems and Specifications5 Manufacturers Specifications and Instructions (made available to the inspector for reference to special requirements for proper application) Safety Data Sheets (needed to ensure that personnel take necessary precautions in handling hazardous materials). Available from Materials manufacturer. 1.2 Certain industries or owners may require certified inspection personnel. See Guide D4537 for establishing procedures to certify inspectors for coating work in nuclear facilities. SSPC offers a training and certification program for concrete coating inspection.5 1.3 In certain cases the inspector may be required to assess the condition of the concrete substrate. SSPC has published an illustrated guide for performing a concrete condition assessment.5 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This guide is arranged in the following order: Section Referenced Documents 2 ASTM Standards 2.1 OSHA Standards 2.2 ICRI Standards 2.3 SSPC Standards 2.4 Significance and Use 3 Preparation for Inspection 4 Surface Preparation Methods and Requirements 5 Surface Preparation 5.1 Factors Affecting Coating Performance 5.2 Surface Condition 5.2.1 Cleanliness 5.2.2 Moisture 5.2.3 Surface Preparation Procedures 5.3 Dry Surface Cleaning 5.3.1 Water and Steam Cleaning 5.3.2 Mechanical Tool Cleaning 5.3.3 Hand Tool Cleaning 5.3.3.1 Power Tool Cleaning 5.3.3.2 Scarifying Machines 5.3.3.3 Preand Post-Surface Preparation 5.3.3.4 Finished Surface 5.3.3.5 Blast Cleaning 5.3.4 Water Blast Cleaning 5.3.5 Acid Etching 5.3.6 Precautions in Preparing Unpainted and Previously Painted Surfaces 5.4 Inspection of Surfaces Prior to Field Painting 5.5 New Construction 5.5.1 Maintenance Repainting 5.5.2 Cracks and Voids 6 Cracks 6.1 Cracks in Concrete 6.1.1 Joints in Concrete 6.1.2 Voids 6.2 Recoat Intervals 6.3 Coating Storage and Handling 7 Storage of Coating and Thinner 7.1 Mixing of Coatings 7.2 Thinning 7.3 Thinning of Coating 7.3.1 Heating of Coating 7.4 Ambient Condition Considerations 8 Drying 8.1 Low Temperature 8.2 High Temperature 8.3 Moisture 8.4 Wind 8.5 Coating Application 9 1 This guide is under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications and is the direct responsibility of Subcommittee D01.46 on Industrial Protective Coatings.
