The performance of this product depends on the degree of surface preparation. All surfaces to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed in accordance with ISO 8504:2000
| assessed and prepared in accordance with the standard. | Accumulated dirt and soluble salts must be removed. Dirt is generally brushed off with a dry bristle brush. Soluble salts should be washed off with fresh water. |
|---|
Blast cleaning: For immersion service, Interdur 8844 must be applied to surfaces blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC SP10. However, for atmospheric exposure, Interdur 8844 should be applied to surfaces blast cleaned to Sa2½ (ISO 8501-1:2007) or at least SSPC SP6.
Surface defects exposed by blast cleaning must be ground, filled or treated by a suitable method.
Recommended angular surface profile of 50–75 µm (2–3 mils).

| Thinner | International GTA007 | Recommended maximum thinning ratio not to exceed 5%. Normally no thinning is required. |
In extreme cases, consult the local technical representative.
Do not thin beyond the requirements of local environmental regulations.
| Cleaner | International GTA007S. Select a cleaning agent compliant with local regulations. For specific usage recommendations, consult your local representative. |
|---|---|
| Interruption of work | Do not allow paint to remain in paint lines, spray guns or spray equipment. Thoroughly flush all equipment with International GTA007S. |
Once mixed, paint should not be resealed. If work is interrupted for too long, mix a fresh batch for application.
| Cleaning | All equipment should be cleaned immediately after use with International GTA 007S. Periodic flushing of spray equipment during the daily work process is a good practice. The frequency of cleaning depends on factors such as spray volume, temperature, spray time, including delays. |

All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Airless spray application provides the highest film thickness in a single coat. When Interdur 8844 is applied by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness. If air spray is used, multiple cross coats are required to achieve maximum film thickness.
Apply under good weather conditions. The surface temperature to be coated must be at least 3 °C (5 °F) above the dew point. During the entire application and curing process, ensure adequate ventilation and air movement to prevent "dead corners"; especially when applying in confined spaces. In special cases, if recoating is required and the film has cured under low temperature and high humidity conditions, before applying the subsequent topcoat, ensure no amine
| salt is present. Condensation on the surface during or after application will lead to a matt surface and poor-quality film. | Premature exposure to standing water will cause colour change. Where a durable decorative surface with good gloss and colour retention is required, overcoat with the recommended topcoat. |

For atmospheric exposure, applied directly to steel, the minimum dry film thickness required for one coat is 350 µm (14 mils); for immersion service, the recommended minimum dry film thickness is 450 µm (18 mils). In both cases, a single coat can be applied by airless spray.
Interdur 8844 is suitable for steel structures under buried conditions (Im3 according to ISO 12944-2). Interdur 8844 can be used in conjunction with sacrificial anode and impressed current cathodic protection systems.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
For immersion service, Interdur 8844 is applied directly to steel.
For atmospheric exposure, the following primers are recommended for Interdur 8844: Intercure 200HS, Intergard 269, Interdur 8816, Interdur 8817, Interzinc 52, Intergard 251. Suitable topcoats are: Interdur 8860, Interfine 3399, Interfine 878, Intergard 740, Interthane 990.
