| New steel | Remove grease with a suitable cleaner and rinse salts and other contamination off the surface with fresh water. Remove weld slag, grind welds and sharp edges smooth, and blast clean to Sa2.5 (ISO 8501-1), ideally achieving a surface profile of Rz 30–75 µm (medium profile on the ISO 8503-1 comparator). Apply the primer within 4 hours of blasting. Steel may also be abraded to St3. |

Note: the above data are measured under well-ventilated conditions, at typical film thickness and 65% relative humidity, and are for reference only.
Actual drying times and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, requirements for early handling and mechanical strength, and other factors. The coating must be fully cured before immersion service.
