| New steel | Remove grease from the surface, and rinse off salts and other contaminants with fresh water. Remove weld slag, grind sharp edges smooth, blast clean to Sa 2.5 (ISO 8501-1), with surface roughness Rz 50–100 µm. |
|---|---|
| Shop-primed surface | Welds, heat-corrected areas and damaged areas must be blast cleaned to Sa 2.5 (ISO 8501-1) or ground with abrasive discs to St 3. |
| Repair | Thoroughly remove grease from the surface, and wash off salts and other contaminants with high-pressure fresh water. |
| Concrete surface | Apply after sealing surface pores with a suitable sealer. |
| Other surfaces | Consult our company. |
The substrate surface temperature must be at least 5 °C and at least 3 °C above the dew point. Ample ventilation is required during application and drying in confined spaces.
Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
| Mixing | This product is supplied as two containers forming one unit. Stir the base thoroughly with a power mixer, add the curing agent in the specified ratio, stir again with a power mixer, and add the recommended thinner to adjust to a suitable application viscosity. Once mixed, use within the specified pot life. |
