Surface Finishing Specifications

The Steel Structures Painting Council (SSPC) has designated fifteen different surface preparation standards including simple solvent cleaning (SP-1) to Commercial Blast Cleaning (SP-6) to Industrial Blast Cleaning (SP-14). Some of these standards are simply visual while others designate specific profiles. These standards are applicable to a large variety surfaces. If a specification has not been designated for a surface to be cleaned or blasted, using an SP standard will provide consistent results from part to part and job to job.
