This standard provides basic requirements for best practices for application of industrial/marine protective coatings to coated or uncoated metallic substrates, and is intended for use by both specifiers and contractors, either in its entirety or by referencing specific sections. It focuses on the coating application process and application-related items that are included as one element of the contractor’s work plan or process control procedures. The scope of this standard includes specific as well as general requirements for the application of liquid coatings applied by brush, spray, or roller. Detailed descriptions of site preparation, surface preparation, pretreatments, or selection of primers and finish coats are beyond the scope of this standard. Appendix A provides additional information about the value and use of project-specific contractor work plans. Appendix B provides an example of language that can be used in procurement/specification documents to specify compliance with requirements of SSPC-PA 1. Appendix C provides a list of additional SSPC reference materials.
