Standard Guide for Painting Inspectors (Concrete and Masonry Substrates)
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 particular job.
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
SSPC-PA Guide 3 - A Guide to Safety in Paint Application5
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)
Material Safety Data Sheets (needed to insure that personnel take necessary precautions in handling hazardous materials). Available from Materials manufacturer.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whomever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
