End Of Warranty Coating Survey Guide

An end of warranty coating survey gives asset owners an independent view of coating performance before the warranty period expires. The best time to plan it is before defects, access constraints, or missing records make claims harder to evidence.

When To Plan The Survey

Plan the survey early enough to inspect, report, review findings, and raise any warranty discussions before the warranty period closes.

Where access requires shutdowns, permits, rope access, vessel support, or traffic management, allow enough lead time for safe planning.

Evidence To Gather

Useful records include coating specifications, contractor inspection records, product data sheets, environmental records, DFT readings, handover documents, previous defect reports, and maintenance history.

Photographs and clear location references are important because warranty discussions often depend on whether defects are isolated, systemic, or linked to specific exposure conditions.

What The Report Should Do

The report should compare observed coating condition against specification, warranty expectations, visible defects, likely causes, and recommended next steps.

Where failure mechanisms are uncertain, the report should recommend further testing or failure analysis rather than overstate the evidence.

FAQ

Common Questions

Is an end of warranty survey different from a normal coating survey?

The inspection methods may overlap, but an end of warranty survey is focused on evidence, specification compliance, defect documentation, and warranty timing.

Should the original contractor attend the survey?

That depends on the contract and warranty process. Independent evidence is useful either way because it provides a clear condition record.
