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 with this primer. If the old film shows chalking or zinc salts, remove the zinc salts and contaminants before applying the intermediate coat or topcoat.
1. Ensure ventilation and exhaust during application; keep away from ignition sources; wear protective equipment such as masks and gloves; maintain adequate ventilation during curing. 2. When mixing paint, stir the base uniformly first, then add the hardener according to the mixing ratio and mix uniformly; adjust thinner consumption according to application requirements and temperature changes; stir thoroughly and allow induction; filtration through a mesh filter is recommended before use; maintain continuous stirring during use. 3. Excessive thinner addition reduces sag resistance; thinner consumption shall not exceed limits in environmental regulations. 4. This product is suitable only for application to blast-cleaned steel surfaces and approved epoxy zinc dust coating and inorganic zinc silicate coating surfaces; it shall not be applied over other types of coatings. Alkyd and alkyd-modified coatings shall not be applied directly over this product's coating. 5. During application and curing, substrate temperature must be above 5°C and at least 3°C above dew point; relative humidity shall not exceed 85%. 6. Cutting structures coated with this paint generates fumes and dust; appropriate protection shall be provided. 7. This product is not suitable for underwater use. 8. Avoid dry spray or excessive film thickness during application. Application of the next coat over a "dry spray" coating may cause pinholes; excessive thickness will extend curing time, handling time and recoating time. Coating thickness must match surface roughness; low film thickness shall not be applied to surfaces with high roughness, and excessive thickness shall be avoided. The paint contains special fillers to improve intercoat adhesion; therefore, the film may appear relatively rough at low thickness, but this does not affect anti-corrosive performance. 9. When work is suspended, do not leave paint in paint lines, spray guns or spraying equipment. Flush all equipment thoroughly with thinner. If the suspension period is too long, it is recommended to mix a new batch of paint for application. 10. All equipment shall be cleaned with thinner immediately after use. Periodic flushing of spraying equipment during daily work is good practice. Cleaning frequency depends on spray volume, temperature, spraying time, including interruption time, among other factors. 11. Residual paint and empty cans shall be disposed of in accordance with relevant local 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.
