AMPP S-CAT case studies

The Spray Coating Application Technician (S-CAT) credential is an AMPP certification aimed at the people who actually pull the trigger on protective coating jobs - spray applicators working on industrial steel, marine structures, tanks, pipelines and similar assets. It is intended to verify that an applicator understands not just how to operate spray equipment, but why each step in the process matters to the finished coating's performance. The exam is delivered in multiple-choice format and is organized around three domains: spray coating application (the largest share, roughly half the content), surface preparation (about a quarter), and safety and inspection (about a quarter). Questions therefore test practical judgment across the whole job sequence - surface preparation and cleanliness before coating, mixing and thinning, gun setup, spray technique, wet and dry film thickness control, environmental limits, and recognizing defects and safety hazards. The AMPP S-CAT case studies are 5 cases and about 2,777 words.
