Continuous on-site supervision of the coating application works
Tests carried out during on-site control:
- random checking of the environmental conditions of the surface-protection work (temperature and humidity of air and object),
- checking the quality of the surface cleaning of the structure,
- after the application of each paint layer:
-
- checking of the coverage degree of the surface and the evenness of the coating (visual inspection),
- measurement of wet coating thickness,
- measurement of dry coating thickness,
- bond test,
|
-
checking the finished coating system on the structure:
-
- check the coverage degree of the surface and the evenness of the coating,
- measurement of total dry coating thickness,
- bond test (grid-cutting test, upright tear-off),
- other necessary tests (measurement of colour, gloss, hardness, breakdown voltage etc.)
|
Based on the on-site checking, a summarized report is prepared, documented with photos, which includes the following:
- coverage degree of the object, condition of the coating system, eventual missing layers or deficiencies,
- measurement results,
- the way of repairing the detected deficiencies,
- qualification of the engineering structure in respect of corrosion protection.
