Before Surface Preparation
Checks may include substrate condition, access, contamination risks, material storage, inspection equipment, specification requirements, and agreement on acceptance criteria.
Clear expectations before preparation starts reduce disputes later in the project.
After Surface Preparation
This is a critical hold point. Inspection may check cleanliness, surface profile, remaining contamination, dust, soluble salts, sharp edges, welds, and environmental conditions before primer is applied.
During And After Application
Hold points can include wet film checks, dry film thickness readings, overcoating intervals, curing conditions, visual defects, stripe coats, repair areas, and final acceptance documentation.
