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 blast cleaning to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between abrasive blast cleaning and application of Intercure 324, the surface should be re-blast cleaned to the specified visual standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by another suitable method.
Recommended angular surface profile of 50–75 µm (2–3 mils).
Intercure 324 is suitable for application to abrasive blast cleaned surfaces which would originally have met the above standard, but the surface may be allowed to stand for 7–10 days under good shop conditions. The surface then degrades to Sa2, but there must be no loose powdery deposits.
Welds and damaged areas of shop-primed steel structures must be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6.
If the shop primer shows large-scale breakdown, the entire area must be blast cleaned.

| 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 | International GTA822 |
|---|---|
| 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.
Intercure 324 can cure below 0°C (32°F). However, the product should not be applied at 0°C (32°F), as ice may be present on the substrate.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
This product shall be thinned only with the recommended International GTA220 thinner. Use of other thinners, particularly ketone-containing thinners, will severely inhibit curing of the coating.
Avoid excessive film thickness, since the adhesion of a topcoat over an aged thick film is not as good as over a film at the specified thickness. When used as a holding primer, avoid excessive film thickness, since intercoat adhesion problems can arise if the subsequent coat is also applied too thickly.
Application of Intercure 324 at excessive thickness extends the minimum recoat interval and handling time and adversely affects long-term recoating performance.
The maximum recoat interval depends on the integrity of the exposed film. A film at 75 µm (3 mils) dry film thickness can generally be recoated after 6 months of exposure, after suitable cleaning and repair of any damaged areas.
Intercoat adhesion of coatings applied over aged Intercure 324 is lower than that over a fresh coating, but still meets the requirements of the specified service.
Intercure 324 is suitable for use in coating systems with selected products for certain chemical environments, since zinc-containing coatings are attacked by acids and alkalis in such environments.
Intercure 324 is not suitable for steel structures likely to be immersed in water.
Owing to rapid fading, the product is not available in light and coloured shades. In addition, like all epoxy resin coatings, Intercure 324 chalks on outdoor exposure. These phenomena do not adversely affect corrosion protection performance.
In addition to abrasive blast cleaned surfaces, Intercure 324 can be applied to other substrates such as stainless steel and alloys. For details, contact International Paint.
The product holds the following approvals: • BS5493:1977 KP1A • UK Department of Transport, Item No. 111 Note: VOC values are typical and given for guidance only. These values may vary with factors such as colour differences and normal manufacturing tolerances.
Intercure 324 is normally applied to suitably prepared steel, for example abrasive blast cleaned steel. However, if required, it can also be applied over a blast-cleaned pre-construction primer. Contact International Paint for specific details.
