Recommended substrate condition and temperature
Substrate condition
- Bare steel: blast cleaning to Sa2½ of ISO 8501-1, with a surface profile of 40–70 µm (1.6–2.8 mil)
- Bare steel: power-tool cleaning to at least St2 of ISO 8501-1
Substrate temperature and application conditions
- During application the substrate surface temperature shall be above 5°C (41°F)
- During application, the substrate surface temperature must be maintained at least 3 °C (5 °F) above the dew point.
Coating system specification
- Coating system for the boottop and topsides of the hull — system sheet SYSTEM SHEET 3102
- Coating system for decks — system sheet SYSTEM SHEET 3103
- Coating system for superstructures and deck outfitting — system sheet SYSTEM SHEET 3104
- Coating system for internal surfaces — system sheet SYSTEM SHEET 3105
Instructions for use
- Stir thoroughly before use
- Before application, bring the paint temperature to 15 °C (59 °F) or above; otherwise thinner may need to be added to adjust the paint viscosity to
a state suitable for application.
- Excessive thinning generally reduces the sag resistance of the wet film
- During application and curing, ensure continuous, adequate ventilation (see sheets {1433} and {1434})
Air spray
Airless spray (single-feed pump)
Brush/roller
