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.
Pre-primed surfaces: InterH2O 699 shall always be applied over the recommended anti-corrosive primer. The primer surface shall be dry and free from all contamination; InterH2O 699 must be applied within the specified recoat interval (refer to the relevant product data sheet).
Areas of breakdown or damage shall be prepared to the grade specified by the standard (e.g. Sa2½ (ISO 8501-1:2007), SSPC SP6 or SSPC SP11), and the primer repaired prior to application of InterH2O 699.
| Mixing | Two-can pack, supplied as one unit. Always mix thoroughly in the specified ratio and use within the specified time. |

(1) Stir Component A with a power mixer.
(2) Combine the entire quantity of hardener (Component B) with Component A and mix thoroughly with a power mixer.
(3) Once mixed, do not reseal the container—increased pressure may cause an explosion.

| Cleaner | International GTA991, followed by clean potable water. |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with clean potable water together with International GTA991. Mixed paint should not be re-sealed. If work is interrupted for a long period, use freshly mixed paint when work resumes. |
| Cleaning | Clean all equipment with International GTA991 immediately after use. Periodic flushing of spray equipment during application is also recommended. Cleaning frequency depends on spray volume, temperature and time, including all interruption periods. Refer to the product application procedure for further details. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Apply by air or airless spray. Flush all equipment thoroughly with GTA991 or ethanol, then rinse with water before applying the coating. For maximum edge protection and film thickness, airless or air spray is recommended. Other application methods, such as brush or roller, may require more than one coat to achieve the specified film thickness.
As with all water-borne coatings, application conditions must be carefully controlled to ensure good performance.
The following basic requirements must be observed: InterH2O 699 shall always be protected from freezing during storage and transport. The recommended storage temperature is 4°C (39°F) to 25°C (77°F).
During application, the steel surface temperature must not be below 10 °C, and must be at least 3 °C above the dew point.
Relative humidity shall be below 80%, otherwise drying and recoat intervals will be considerably extended. The film will be more prone to foaming. Good ventilation around the coated object is also essential [minimum air velocity 0.1 m/sec].
Some small areas that are difficult to ventilate shall be applied by brush to avoid overspray.
Overspray of InterH2O 699 will extend the minimum recoat interval and handling time. Overspray also increases micro-foaming in the film and reduces gloss.
To ensure good ageing recoatability of InterH2O 699 when overcoated with other coatings, the surface must be clean, dry and free from contamination, particularly where the surface is rough due to the presence of micaceous iron oxide.
The following primers/intermediate coats are recommended for InterH2O 699: Intercure 200HS, Intercure 420, Intergard 251, Intergard 475HS, InterH2O 401, InterH2O 499, Interplus 356. The following topcoats are recommended in systems with InterH2O 699: InterH2O 699, Interseal 121, Interthane 990. For other suitable primers/intermediate coats, consult International Paint Industrial Coatings.
