*Practical consumption is affected by equipment, operator technique and application environment; determine the practical consumption according to actual conditions.
Recoat time* Temperature
| 5°C | Minimum (h) 36 | Maximum (days): 21 |
| 10°C | 24 | 14 |
| 20°C | 12 | 7 |
| 30°C | 6 | 7 |
*The overcoating interval depends on subsequent exposure. As the film may chalk or pick up other contaminants after prolonged exposure to a polluted environment, the existing coating surface shall be abraded; loose impurities such as grease shall be washed off with high-pressure fresh water or wiped with thinner, and the surface allowed to dry before overcoating.

- 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.
Where in direct contact with the substrate, all surfaces to be coated shall be clean, dry and free from contamination. Before painting, all surfaces shall be assessed and prepared in accordance with ISO 8501. Blast clean to Sa2½ with a surface profile of 40–75 µm. Before derusting, remove all oil, grease and weld spatter, and grind welds and sharp edges.
Areas that cannot be blasted must be cleaned with power tools to St 3, free of oil and water, with no loose material.
When the product is overcoated on other air-drying or chemically curing coatings, first confirm compatibility with the previous coat and check the overcoating interval of the previous coat. If the interval is exceeded, the previous coat shall be abraded, loose film removed by power tool, and other loose impurities removed; the surface shall be free of oil and water.
