All surfaces to be coated shall be clean, dry and free from contaminants. Before coating, all surfaces shall be assessed and prepared in accordance with ISO8504: 2004. Intergard 263 shall be applied over the recommended primer coating system. The primer surface shall be dry and free from any contaminants (oil, grease, salt and other contaminants), and Intergard 263 shall be applied within the specified recoat interval (refer to the relevant primer product Data Sheet).
Areas with peeling and damage shall be treated to the specified standard (for example, Sa2½ (ISO 8501-1:2007) or SSPC-SP6 abrasive blast cleaning standard, or SSPC-SP11 manual/power tool cleaning standard), and these areas shall be spot-primed before application of Intergard 263.
Consult an International Paint representative for specific advice.
| 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. |

| Thinner | International GTA220. | Normally no thinning is required. |
In extreme cases, consult the local technical representative.
Do not thin beyond the requirements of local environmental regulations.
| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Do not leave paint residues in hoses, spray guns or spray equipment. Thoroughly flush all equipment with International brand cleaner. |
Once a paint kit has been mixed, it shall not be resealed. If application is interrupted for an extended period, remixing the components before restarting application is recommended.
| Cleaning | All equipment shall be cleaned immediately after use with International brand cleaner. During the working day, periodic flushing of spray equipment is good working practice. The number of cleaning operations depends on spray volume, temperature and working time (including downtime). Do not exceed the pot life. |

All surplus paint and empty containers must be disposed of in accordance with appropriate local regulations/laws.
Intergard 263 is mainly a transitional coating between anticorrosive coatings and antifouling coatings, ensuring optimal system adhesion on vessel hull areas.
Airless spray is the ideal method to achieve the maximum film thickness in one coat. Application methods other than airless spray are unlikely to achieve the required film thickness.
Low or high temperatures may require specific application techniques to achieve the maximum film thickness.
When Intergard 263 is applied by brush or roller, multiple coats are necessary to achieve the specified total dry film thickness of the system.
Below 5 °C (41 °F), the product will not cure adequately.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Ensure adequate ventilation when applying Intergard 263 in confined spaces.
Recoat data are for guidance only and shall depend on local climatic and environmental conditions. For specific advice, consult the local International Paint representative.
Exposure to mist or rain before the specified hard-dry time will damage the surface appearance and then impair overall performance. This is particularly noticeable in dark-coloured coatings.
As with all epoxy systems, the product may chalk and discolour under exterior exposure; consult an International Paint representative for specific advice..
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Intergard 263 is designed for application to suitably prepared steel.
Suitable primers: Intergard 343, Intergard 787, Intershield 300, Interzinc 22*, Interzinc 52*. A sealer may be required. Suitable topcoats are:
| Intergard 263 | Interthane 870 |
|---|---|
| Intergard 740 | Interthane 990 |
| Interthane 990E | Intersmooth 7465HS SPC. For other suitable primers/topcoats, consult International Paint. |
