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 8504:2019.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Abrasive blasting: blast clean to at least Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Interdur 8816, re-blast the surface to the specified visual standard. Surface defects exposed by the blast cleaning process shall be ground, filled or treated by other suitable methods.
Recommended surface profile 40–75 µm (1.6–3.0 mil).
| Mixing | This product is supplied in two containers forming one unit. Mix the two components in the specified ratio in one operation. Once mixed, use within the specified pot life. |

| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Mixed paint should not be resealed. If work is interrupted for too long, mix a fresh batch of paint for application.
| Cleaning | All equipment should be cleaned immediately after use with International thinner. 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. |
|---|
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
For good anticorrosive performance, a minimum film thickness of 60 µm is important. The film thickness of the product shall match the surface profile of the substrate; on a high-profile substrate, a low film thickness shall not be applied.
Care shall be taken to avoid applying a dry film thickness above 150 µm (6 mil). Avoid over-thick application; if the film is too thick, cracking may result from cohesive failure. Dry spray shall also be avoided, otherwise pinholes will appear.
Over-application of Interdur 8816 will extend the minimum recoat time and handling time and adversely affect long-term recoatability.
Where Interdur 8816 is permitted to weather before topcoating, ensure that all zinc salts are removed prior to painting and apply the topcoat using only the recommended materials.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Interdur 8816 is not recommended for underwater use. Consult International Protective Coatings for details.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Recommended topcoats include: Interdur 8840, Interdur 8841, Interdur 8860, Intergard 475HS. For other suitable topcoats, consult International Paint Protective Coatings.
