Prior to coating, a suitable surface preparation must be performed according to the coating system manufacturer and the coating contract specification. To ensure that the applied coating system performs as designed, during the surface preparation stage several tests and the corresponding services that can be provided such as:
- Visual inspection for the determination of rust grade (ISO 8501-1, ISO 8501-2)
- Measurement of dust on the surface (ISO 8502-3)
- Surface chemical cleanliness - Measurement of Chloride ions (ISO 8502-6)
- Blast cleaning media cleanliness – Chloride ions determination (ISO 8502-6)
- Surface roughness/profile (ASTM D4417, ISO 8503)
- Water pH measurement
