All surfaces to be coated must be clean, dry and free from contamination. Before coating, all surfaces must be assessed and treated in accordance with ISO 8504:2000. On areas of the coated film that have suffered mechanical damage with local rusting, blast clean locally to Sa 2½ or prepare to St 3 by power tool, touch up with primer, and then apply the product. When applying over other old coatings, remove chalked film, zinc salts, grease and other contaminants by a suitable method. When applying over inorganic zinc silicate primer or thermally sprayed metal, an approved tie coat or intermediate coat must be used.
1. During application, ensure ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as masks and gloves; adequate ventilation should also be maintained during curing. 2. When mixing, stir the base thoroughly first, then add the curing agent in the specified ratio and mix thoroughly; adjust the amount of thinner according to application needs and temperature changes, and stir thoroughly and induce. 3. When applying over inorganic zinc silicate coating, seal it with an intermediate coat; the intermediate tie coat must be hard dry before applying this product, otherwise the effectiveness of sealing pinholes will be reduced. The product may also be thinned to a sufficiently low viscosity and used as a sealer. 4. Over-thinning reduces sag resistance and slows curing. 5. Over-application seriously affects drying, curing, recoating performance and handling time. Avoid applying excessively thick single coats on structural edges, corners, welds and other areas. 6. If the coating chalks after long-term exposure, wash with high-pressure water or abrade the surface before applying the subsequent coat. 7. Roller application cannot achieve high film thickness and a good continuous film in a single pass; multiple coats are required. 8. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, and the relative humidity must not exceed 85%. 9. Cutting structures coated with this product produces smoke and dust; take appropriate protection. 10. When work is interrupted, do not leave the coating in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is too long, mix a fresh batch of paint for application. 11. All equipment should be cleaned with thinner immediately after use. Periodic flushing of spray equipment during the working day is good practice. The cleaning frequency depends on spray volume, temperature, spray time and factors including interruptions. 12. Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.

Keep sealed in a ventilated, cool, dry place away from sources of ignition. Minimum 12 months.
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.
