All surfaces to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed and prepared in accordance with GB 18839-2002.
Remove any oil and grease by solvent cleaning in accordance with GB 18839-2002.
Blast cleaning: blast clean to Sa 2.5 (GB 8923-1:1998). If the steel surface oxidises after blasting and before overcoating with Interdur 8802, the surface should be re-blasted to the specified visual standard. Surface defects exposed by blasting should be ground, filled or treated by a suitable method.
Interdur 8802 is suitable for surfaces initially prepared by blast cleaning as described above, then allowed to degrade naturally under good shop conditions for no more than 7 to 10 days. The surface may degrade to Sa 2, but must be free from loose powdery rust.
Surface defects exposed during blasting must be ground, filled or treated by a suitable method.
Recommended angular surface profile of 50–75 µm (2–3 mils).
Interdur 8802 is suitable for application to blast-cleaned surfaces that originally met the above standard but have been allowed to weather under good shop conditions for 7-10 days. The surface then degrades to Sa 2, but must be free from loose powdery deposits.
Welds and damaged areas of shop-primed steel must be blast cleaned with steel grit to Sa 2.5 (GB 8923-1:1998). If the shop primer has sustained extensive or scattered breakdown, a full sweep blast may be required. If the shop primer has been applied over a blast-cleaned surface, a full sweep blast with steel grit is required before applying Interdur 8802.

Interdur 8802 is preferred in systems for certain chemical environments, because in such environments zinc-containing coatings may be 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.
Interdur 8802 is not suitable for steel structures that may be immersed in water.
In addition to blast-cleaned surfaces, Interdur 8802 can be used on other substrates, such as stainless steel and alloys. Consult International for details.
The intercoat adhesion of a coat applied over aged Interdur 8802 is lower than that over a fresh coat, but it is still adequate for the specified purpose.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
The following topcoats/intermediate coats are recommended for Interdur 8802: Interdur 8840, Interdur 8842, Interdur 8860. For other suitable topcoats/intermediate coats, consult International.
