All surfaces to be coated should be clean, dry and free from contaminants. Before coating, all surfaces should be assessed and prepared in accordance with ISO 8504:2000. Abrasive blast clean to Sa2½ with a surface profile of 40–75 µm. Before rust removal, oil, grease and welding spatter must be removed completely, and welds and sharp edges ground. Where the coating film of this product is mechanically damaged and local rusting appears, local abrasive blast cleaning to Sa2½ or power tool cleaning to St3 is required before local repair with this primer. If chalking or zinc salts appear on the surface of the old coating film, remove the zinc salts and contaminants from the surface before applying the intermediate coat or topcoat.
1. Ensure adequate ventilation and exhaust during application, keep away from ignition sources, and wear protective equipment such as masks and gloves; adequate ventilation shall also be maintained during curing. 2. When mixing, first stir the base to a uniform state, then add the hardener at the specified ratio and mix uniformly; adjust the thinner quantity to suit application requirements and temperature variation, stir thoroughly and allow to induct. Passing through a 120-mesh screen before use is recommended, and continuous agitation is required during use. 3. Excessive thinner addition reduces sag resistance; the thinner quantity must not exceed the limits of environmental regulations. 4. The product is suitable for application only to abrasive blast cleaned steel surfaces and to approved epoxy zinc-rich and inorganic zinc silicate coating surfaces, and cannot be applied over other types of coating. Alkyd and alkyd-modified coatings cannot be applied directly over the coating of this product either. 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 exceeding 85%. 6. Cutting structures coated with this paint generates fume and dust; appropriate protection shall be provided. 7. The product is not suitable for underwater service. 8. Avoid dry spray and excessive film thickness during application. Application of the next coat over a dry-sprayed film may cause pinholes, and excessive thickness extends curing, handling and recoating times. Film thickness must be matched to the surface roughness; low film thickness shall not be applied to surfaces with high roughness, and excessive thickness shall be avoided. 9. When work is suspended, do not leave paint in the paint line, spray gun or spray equipment. Flush all equipment thoroughly with thinner. If the suspension is prolonged, mixing a fresh batch of paint for application is recommended. 10. All equipment shall be cleaned with thinner immediately after use. Periodic flushing of spray equipment during the daily work routine is good practice. Cleaning frequency depends on spray volume, temperature, spraying time, including interruption time and other factors. 11. Residual paint and empty containers shall 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.
