All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Interplate 408, the surface shall be re-blasted to the specified visual standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by another suitable method.
Recommended surface roughness 35–50 µm (1.5–2.0 mil); edges shall also be rounded smooth. Blasting with angular grit may produce excessive sharp peaks on the surface, which can penetrate the primer film and cause early corrosion.
| Mixing | This product is supplied in two containers as one unit. Always mix the entire unit in the specified ratio. Once mixed, use within the specified pot life. |

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA803. Once mixed, a batch of paint shall not be re-sealed; if work is interrupted for too long, remix a fresh batch of paint. |
| Cleaning | All equipment should be cleaned immediately after use with International GTA 803. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including interruptions, and other factors. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local laws/regulations.
Interplate 408 is designed for automatic spray plants. It may be applied by manual spraying but is not recommended for complex structural components.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
DFT above 30 µm (1.2 mil) or below 20 µm (0.8 mil) may adversely affect film appearance and performance.
At film thickness above 30 µm (1.2 mil), weld fume and weld porosity increase.
Drying time depends on substrate temperature and ventilation.
Shop primer is not recommended as a repair primer after fabrication.
This product holds the following approvals: weldability certified by the Newcastle City Council Occupational Health Service; weldability also certified by Lloyd's Register. Note: the VOC value is typical and for guidance only. The value may vary with colour differences and normal production tolerance.
The following topcoats are recommended for use with Interplate 408: Intergard 251 Intergard 269 Intergard 400 Intergard 410 Interprime 198 Interseal 670HS Interzone 505. For other suitable topcoats, consult International Protective Coatings.
