Project & Environment
- Structure ID / coating area designation *
- Date of inspection *
- Is the coating system a new application, maintenance overcoat, or condition survey? *
- Are ambient conditions (temp, humidity, dew point, surface temp) within specification? *
Surface Preparation
- Does abrasive blast cleanliness meet the specified SSPC grade (e.g., SP 10 near-white)? *
- Is the surface profile (anchor pattern) within the specified range? *
- Measured surface profile (mils)
- Are soluble salt/chloride levels below specified limits?
Coating Application & Thickness
- Does dry film thickness (DFT) of each coat meet SSPC-PA 2 acceptance? *
- Measured total DFT (mils)
- Is the coating free of runs, sags, overspray, dry spray, and pinholes? *
- Do holiday/pinhole detection results (where required) pass?
Adhesion & Existing Condition
- Does adhesion testing (pull-off / X-cut) meet the specified minimum?
- Is the existing coating free of active rust, blistering, cracking, or delamination? *
- Estimated percent of area with coating breakdown (%)
Actions
- Is spot repair, overcoat, or full recoat recommended? *
- Findings and recommended actions
