Zinc salts form on zinc-rich primer surfaces; before overcoating, the coating shall not be exposed outdoors for prolonged periods.
Before overcoating, any visible contamination on the surface shall be removed as appropriate, by high-pressure water washing, sweep blasting or power tool cleaning depending on the situation.

- Adequate and continuous ventilation must be maintained during application and curing of the coating.
- When applying at ambient air or substrate surface temperatures below 5 °C, pre-warm the mixed paint to above 10 °C.
Abrasive blast clean to Sa 2½ (ISO 8501-1) or at least SSPC-SP6, with surface roughness 40–70 µm after blasting.
| Surfaces coated with a type-approved inorganic zinc silicate shop primer | Sweep blast clean to Sa 1 (ISO 8501-1) (SSPC-SP7) or prepare with power tools to St 3 (ISO 8501-1) (SSPC-SP3). |
