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 8504:2000. Abrasive blast clean to Sa 2½, with surface roughness 40–75 µm. Before rust removal, remove all oil and weld spatter and grind welds and sharp edges. Areas of the coating damaged mechanically and showing localised rust must be spot blast cleaned to Sa 2½ or cleaned with power tools to St 3 before local repair. If this coating is to be applied over an approved zinc dust primer old film, thoroughly remove any chalking or zinc salts before applying this product.
1. During application, ensure ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as a mask and gloves; maintain adequate ventilation also during curing. 2. Before mixing, stir Component A with a power tool, then add the curing agent and mix well; adjust the thinner quantity according to application needs and temperature, stir thoroughly and allow induction for 10–15 minutes before application. 3. Do not use paint beyond its pot life, otherwise the chemical resistance of the coating is severely affected. 4. This product is a primer/topcoat combined product, suitable only for blast-cleaned steel surfaces and approved zinc dust coatings; it must not be applied over other coating types, nor other coatings applied over it, otherwise static dissipation is affected. 5. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, with relative humidity not more than 85%. Temperature and relative humidity must be measured on the substrate near the work area. The paint temperature must not be below 10 °C. 6. The recommended dry film thickness per coat should not exceed 150 µm, otherwise retained solvent affects chemical resistance; multiple coats reduce coating defects and improve anti-corrosion performance. At ambient temperature, cure for 7–10 days before service; at low temperatures, extend curing (14–21 days) or use heating. Do not use this product below 5 °C. 7. If applying over a zinc dust primer old film, thoroughly remove any chalking or zinc salts, and confirm the surface resistance of the old coating meets requirements before applying this product. 8. Cutting of structures coated with this product produces fume; take appropriate protection. 9. When work is interrupted, do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is long, mix a fresh batch of paint for application. 10. Clean all equipment immediately after use with 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. 11. Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.

1. For the coating and its recommended thinners, see the safety sheets and the safety data of the relevant materials. This is a solvent-borne coating; avoid inhaling spray mist and solvent vapours, and avoid exposing skin and eyes and contact with uncured paint as far as possible. 2. All work related to the application and use of this product must comply with the relevant national health, safety and environmental standards and regulations. 3. If welding or flame cutting is required on metal coated with this product, dust and fumes will be generated; use appropriate personal protective equipment and adequate local ventilation. 4. If in doubt about the suitability of this product, consult the company.
