| description abstract | 3.1 This guide is intended as a reference for those responsible for the inspection of thin- or thick-film coating application to concrete and masonry substrates. It does not address the application of cementitious-type coatings. The requirements for inspection should be addressed in all protective coating and lining work specifications. This guide may be used by specification writers when selecting and establishing the inspection requirements for coating and lining specifications. A sample checklist for use by inspectors is included as Appendix X1.1. | |

| scope | 1.1 This guide is intended as an information aid to painting inspectors in carrying out their tasks correctly and 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 Steel Structures Painting Manual Vol. 1 - Good Painting Practices4 Steel Structures Painting Manual Vol. 2 - Systems and Specifications4 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. AMPP offers a training and certification program for concrete coating inspection.4 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.4 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 Pre- and 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 Residual Contaminants 9.1 Quality Assurance 9.2 Film Defects 9.2.1 Brush Application 9.3 Spray Application 9.4 Roller Application 9.5 Miscellaneous Methods 9.6 Rate of Application 9.7 Additional Considerations 10 Ventilation 10.1 Painting Schedule 10.2 Film Integrity 10.3 Recoat Time 10.4 Coating System Failure 10.5 Inspection Equipment 11 General 11.1 Adhesion of Existing Coating 11.1.1 Portable Pull-Off Adhesion 11.1.2 Field Inspection Equipment 11.2 Drying and Curing Times 11.2.1 Thermometers 11.2.1.1 Psychrometric Charts 11.2.1.2 Wet-Film Thickness Gauges 11.2.2 Notched Gage 11.2.2.1 Dry-Film Thickness Gauges 11.2.3 Destructive Thickness Gauge 11.2.3.1 Nondestructive Film Thickness Gauges 11.2.3.2 Discontinuity (Holiday) Tester 11.3 Inspection Checklist Appendix X1 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
