Scope

1.1 This guide is intended as an information aid to painting inspectors in carrying out their 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 the specification of a particular job. NOTE 1—For additional helpful information, refer to the following documents: Manual of Coating Work for Light-Water Nuclear Power Plant Primary Containment and Other Safety-Related Facilities 2 New Concepts for Coating Protection of Steel Structures3 D16 Terminology for Paint, Related Coatings, Materials, and Applications4 D4538 Terminology Relating to Protective Coatings and Lining Work for Power Generation Facilities4 Steel Structures Painting Manual Vol 1 Good Painting Practice5 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 coatings work in nuclear facilities. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This guide is arranged in the following order: Section Referenced Documents 2 ASTM Standards 2.1 OSHA Standards 2.2 Steel Structures Painting Council Publications 2.3 International Standards Organization (ISO) 2.4 ASTM Adjuncts 2.6 Significance and Use 3 Preparation for Inspection 4 Surface Preparation Methods and Requirements 5 Surface Preparation 5.1 Pictorial Standard D2200 5.1.1 Factors Affecting Coating Performance 5.2 Cleanliness 5.2.1 Mill Scale 5.2.2 Surface Profile 5.2.3 Sharp Edges 5.2.4 Cleaning Procedures 5.3 Chemical Cleaning 5.3.1 Solvent Vapor Cleaning 5.3.1.1 Hand Tool Cleaning 5.3.2 Power Tool Cleaning 5.3.3 Power Tool Cleaning to Bare Metal 5.3.4 Commercial Grade Power Tool Cleaning 5.3.4.4 Blast Cleaning 5.3.5 Pressurized Water Cleaning 5.3.6 Cleaning and Preparation of Various Surfaces 5.4 Steel Surfaces 5.4.1 Galvanized Surfaces 5.4.2 Aluminum Surfaces 5.4.3 Precautions in Preparing Unpainted and Previously Painted Surfaces 5.4.4 Inspection of Surfaces Prior to Field Painting 5.5 New Construction 5.5.1 Maintenance Repainting 5.5.2 Coating Storage and Handling 6 Storage of Coating and Thinner 6.1 Mixing of Coatings 6.2 Thinning 6.3 Initial Samples 6.3.1 Thinning of Coating 6.3.2 Sampling of Thinned Coating 6.3.3 Heating of Coating 6.4 Weather Considerations 7 Drying 7.1 Low Temperature 7.2 High Temperature 7.3 Moisture 7.4 Wind 7.5 Coating Application 8 Residual Contaminants 8.1 Quality Assurance 8.2 Film Defects 8.2.1 Brush Application 8.3 Spray Application 8.4 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.
