*The maximum recoat interval depends on the exposure environment and the end use of the coating.
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
assessed and prepared in accordance with. 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 another primer, intermediate coat or topcoat.
| 1. | During application, ensure good ventilation and exhaust, keep away from ignition sources, and wear a mask, gloves and other protective equipment; during curing, adequate ventilation shall also be |
|---|
maintained.
| 2. | With the liquid component stirring, slowly add the zinc dust component, and mix thoroughly with a power tool; adjust the thinning according to application |
|---|
requirements and temperature, mix thoroughly, and strain through a 120-mesh sieve before use, stirring continuously during use. If the zinc dust is poured directly into the liquid component, or if thinner is added before mixing, the paint will be difficult to mix uniformly and defects such as gun blockage and uneven film are likely. Stir continuously during application to prevent zinc dust settling.
| 3. | The maximum permitted film thickness of this product is 120 µm; over-thick application may cause cracking. During application, attention shall be paid to |
|---|
the treatment of edges and corners of the workpiece and avoid over-thick application to prevent cracking.
| 4. | The product is suitable only for application over blast-cleaned steel surfaces and shall not be applied over other types of coatings. |
|---|
On substrates with an excessively low profile or on smooth surfaces, the coating cannot achieve good adhesion and may even detach.
| 5. | 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.
| 6. | Cutting structures coated with this coating produces fumes; appropriate protection shall be taken. |
|---|---|
| 7. | When applying other coatings over this product, sealing shall be carried out in advance; a dedicated sealer |
primer is recommended, or the subsequent epoxy coating may be thinned and mist-coated to seal the surface and avoid blistering. Alkyd, alkyd-modified and polyurethane coatings shall not be applied directly over this product.
| 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.

The shelf life of this product is 12 months (at 23 °C ± 2 °C). Store in a dry, ventilated environment. Containers shall be kept sealed.
| 1. | Avoid inhaling spray mist and solvent, and avoid exposing skin and eyes or contact with wet paint. |
|---|---|
| 2. | All work related to the application and use of this product shall be carried out in accordance 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; therefore |
|---|
suitable personal protective equipment and adequate local exhaust ventilation shall be used.
| 4. | If in doubt about the suitability of this product, consult the company. |
