| New steel | Remove grease from the surface with a suitable cleaner, and rinse off salts and other contaminants with fresh water. Remove weld slag, and grind welds and sharp edges smooth. Abrasive blast clean to Sa 2.5 (ISO 8501-1); the ideal surface roughness is Rz 40–75 µm (medium roughness on the ISO 8503-1 comparator). Apply the primer within 4 hours of blast cleaning. |
|---|---|
| Repair of galvanised surfaces | Thoroughly remove grease from the surface with a suitable cleaner, wash off salts and other contaminants with high-pressure fresh water, grind small rusted areas with power tools, and touch up with this product. |
Ambient temperature for application -5 to 50 °C, air relative humidity not exceeding 95%, and the steel surface temperature shall be at least 3 °C above the dew point; outdoor application is prohibited in rain, fog, snow, strong wind and heavy dust.
In hot summer weather, guard against dry spray; provide ample ventilation during application and drying in confined spaces;
1. Thoroughly remove oil, grease, moisture and dust from the areas to be painted.
2. Before spraying, shake the can up, down, left and right for about two minutes so that the paint is fully mixed.
3. At about 20–30 cm from the surface to be coated, press the nozzle with the index finger and spray back and forth evenly.
4. Use multiple light sprays, applying a thin coat every two minutes, which gives a better result than a single heavy coat.
5. Before storing after use, invert the can and press the nozzle for about 3 seconds to clear residual paint and prevent clogging.
2. After opening, stir evenly and adjust to the appropriate application viscosity with thinner.
3. Air spray is recommended, about 10–15 µm per pass; two passes are preferred. Brush and roller may cause colour variation.
5. Unused paint can be sealed and stored for continued use.
