SSPC's most widely used visual reference features over 50 full-color photos of previously coated and uncoated, rusted steel surfaces before and after dry abrasive blast cleaning. Cleanliness requirements for conditions depicted are defined by the SSPC surface preparation specifications for white metal (SP 5), near-white (SP 10), commercial (SP 6), industrial (SP 14), and brush-off (SP 7) blast finishes. Appendix photographs show variations in white metal surfaces caused by different metallic and non-metallic abrasives, profile depth, angle of view, and lighting. Now with guides in both English and Spanish!
