What is the primary responsibility of a NACE CIP Level 2 inspector on a coating project?
✔✔To perform advanced inspection, verify compliance with specifications, and document
coating quality.
What distinguishes a Level 2 coating inspector from a Level 1 inspector?
✔✔Greater authority to evaluate complex coating systems, troubleshoot problems, and interpret
specifications.
Why is understanding project specifications critical for a CIP Level 2 inspector?
✔✔Specifications define acceptance criteria, materials, procedures, and inspection hold points.
What is the main purpose of a coating inspection plan?
✔✔To outline inspection activities, frequencies, and documentation requirements.
Why must surface cleanliness be verified before coating application?
✔✔Contaminants can prevent adhesion and cause premature coating failure.
What condition must steel be in before applying a primer?
✔✔Clean, dry, and free of oil, grease, dust, and visible corrosion.
1
,What does surface profile influence most in a coating system?
✔✔The mechanical adhesion of the coating to the substrate.
Why is excessive surface profile undesirable?
✔✔It can cause inadequate coating coverage at peak areas.
What is the purpose of measuring surface temperature during inspection?
✔✔To ensure it is above the dew point and suitable for coating application.
Why must inspectors calculate dew point on site?
✔✔To prevent condensation that leads to adhesion failure.
What is the primary function of a coating primer?
✔✔To promote adhesion and provide initial corrosion protection.
Why are intermediate coats important in multi-coat systems?
✔✔They build film thickness and enhance barrier protection.
What role does a topcoat play in a coating system?
✔✔It provides resistance to weathering, UV exposure, and chemicals.
2
, Why must wet film thickness be checked during application?
✔✔To confirm the applied coating will achieve the specified dry film thickness.
What does dry film thickness measurement verify?
✔✔That the cured coating meets specification requirements.
Why is over-application of coating a concern?
✔✔It can cause sagging, cracking, solvent entrapment, or extended curing times.
What is the purpose of recoat intervals?
✔✔To ensure proper bonding between successive coating layers.
Why should coating materials be mixed according to manufacturer instructions?
✔✔Improper mixing can affect curing, performance, and durability.
Why is pot life important for two-component coatings?
✔✔Once exceeded, the coating may not cure properly.
What is flash rust and why must it be controlled?
✔✔Light rust forming after blasting that can reduce coating adhesion.
Why should blast-cleaned surfaces be inspected immediately?
