Frequently asked questions
When should this inspection be used?
Use it after each coat is cured and ready for measurement, or at final closeout to confirm total system thickness. It helps catch coating issues before the job is accepted.
What does DFT mean in this template?
DFT stands for dry film thickness, the cured thickness of a coating layer. This template records measurements for primer, intermediate, and finish coats against the project specification.
Can this template support multiple measurement points?
Yes. It includes required sample-point recording so inspectors can document readings across the asset or area being coated. That makes it easier to show compliance and spot thin or inconsistent areas.
Does the template include calibration checks?
Yes. It prompts for gauge calibration status, zero checks, and verification against shims or certified standards before measurements are taken. That supports reliable readings and audit-ready records.
Who typically uses this template?
Quality inspectors, coating contractors, and project supervisors use it to confirm coating work meets specification. It is useful wherever protective or decorative coatings must be verified before handoff.
