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.
Blasting: blast-clean with steel grit to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blasting and application of Intercure 1039, re-blast the surface to the specified visual standard.
Surface defects exposed by blast cleaning must be ground, filled or treated by a suitable method.
A sharp, angular surface profile of 50–75 µm (2–3 mil) is recommended.
Intercure 1039 is suitable for surfaces initially blast-cleaned to the above standard and then allowed to degrade naturally for no more than 7–10 days under good shop conditions. The surface may fall to Sa 2, but must be free of loose powdery rust.
Welds and damaged areas of shop-primed steel structures shall be blast-cleaned with steel grit to Sa2½ (ISO 8501-1:2007) or SSPC SP6.
If the shop primer shows extensive or scattered breakdown, a full sweep blast may be required.
If the shop primer was applied over shot-blasted surfaces, a full sweep blast with steel grit is required before applying Intercure 1039.

| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. 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 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. |
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Intercure 1039 is best used with certain products for some chemical environments, where zinc-containing coatings are attacked by acids and alkalis.
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.
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.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
This product must be thinned only with the recommended International thinner. Other thinners, especially those containing ketones, severely inhibit the curing of the coating.
Low-temperature curing: Intercure 1039 cures below 0 °C (32 °F). However, it should not be applied at 0 °C (32 °F) because ice may be present on the substrate.
For details of curing times and recoatability, contact International Paint.
Because of fast fading, this product has no light or tinted shades. In addition, like all epoxy resin paints, Intercure 1039 chalks under exterior exposure.
However, these phenomena do not adversely affect the anticorrosive performance.
Intercure 1039 is not suitable for steel structures that may be immersed in water.
Besides blast-cleaned surfaces, Intercure 1039 can also be used on other substrates such as stainless steel and alloys. Consult International Industrial Coatings for details.
Intercoat adhesion over aged Intercure 1039 is lower than over fresh coating, but still adequate for the specified use.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Intercure 1039 is normally applied over suitably prepared steel, e.g. blast-cleaned. However, if required, it can also be applied over blast-primed surfaces. Consult International Industrial Coatings for details.
The following primers can be used with Intercure 1039:
| Interzinc 22 - QHA028 | *(a mist coat or tie coat may be required). The following topcoats/intermediate coats are recommended for use with Intercure 1039: Intercure 1040, Interfine 878, Intergard 475HS, Intergard 740, Interseal 670HS, Interthane 990, Interzone 954, Interzone 1000. For other suitable topcoats/intermediate coats, consult International Industrial Coatings. |
