Applications and use cases
Recommended systems and compatibility
- Use only over recommended anticorrosive primers appropriate to the vessel area and application location.
- Typical use as the cosmetic finish in a multi-coat marine system in accordance with standard Worldwide Marine Specifications.
- Can be applied directly over aged Intersheen 579 after thorough fresh water washing and degreasing, provided the existing coating is intact and tightly adherent.
Surface preparation
- All surfaces must be clean, dry and free from contamination.
- High pressure fresh water wash or fresh water wash as appropriate.
- Remove oil, grease and soluble contaminants in accordance with SSPC-SP1 solvent cleaning.
- Areas of breakdown or damage should be prepared to the specified standard (e.g. Sa2½) and re-primed before applying Intersheen 579.
Application guidance
- Mix thoroughly with a power agitator before application; this is a one pack coating.
- Airless spray is recommended for general application.
- Brush and roller application are recommended for small areas only; multiple coats may be needed to reach the specified dry film thickness.
- Use International GTA007 thinner only in exceptional circumstances and not beyond limits set by local environmental legislation.
- Clean all equipment with GTA007. Filter material before use, especially from partially used containers which may show surface skinning or viscosity increase.
- Apply in good weather with the surface temperature at least 3°C above the dew point.
- For optimum application properties, bring material to 21–27°C before mixing and application unless otherwise specified.
