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 from the zinc dust coating before applying this product. For concrete protection, the concrete must be cured, with moisture content and surface condition meeting the relevant requirements.
1. During application, ensure good ventilation and exhaust, keep away from ignition sources, and wear a mask, gloves and other protective equipment; adequate ventilation shall also be maintained during curing. 2. Before mixing the two components, stir the base thoroughly with a power tool, then add the curing agent and mix uniformly; adjust the thinner amount according to application requirements and temperature changes, mix thoroughly, and allow an induction time of 10–15 min before application. 3. Before applying the next coat, ensure the sealer is hard dry, otherwise the effectiveness of sealing pinholes will be reduced. If the coating is to be applied over an old zinc dust primer film, chalk or zinc salts on the zinc dust coating shall be removed thoroughly. 4. If the coating chalks after long-term exposure, wash with high-pressure water or abrade the surface before applying the next coat. 5. When used to seal thermally sprayed metal, the metal layer shall be coated within the overcoating interval specified by the design specification. 6. During application and curing, the substrate temperature shall be above 5 °C and at least 3 °C above the dew point, and the relative humidity shall not exceed 85%. Temperature and relative humidity shall be measured on the substrate close to the work area. 7. Cutting structures coated with this coating produces fumes; appropriate protection shall be taken. 8. When work is interrupted, do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If work is interrupted for too long, remix a fresh batch of paint before resuming. 9. All equipment shall be cleaned with thinner immediately after use. Periodically flushing spray equipment during the daily work is good practice. The frequency of cleaning depends on the quantity sprayed, temperature, spraying time and interruptions. 10. Remaining 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.
