Application

Steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting to Sa 2½ (ISO 8501-1:2007).

Stainless steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. To be abrasive blasted to a uniform, sharp, dense profile, ISO Comparator Medium (G), corresponding to Rz minimum 50 micron.

Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Minimum relative humidity: 50% . At relative humidity below 70%, curing is retarded. Use only where application and curing can proceed at temperatures above: 5°C/41°F. In confined spaces provide adequate ventilation during application and drying.

The coating will be fully cured after: 7 days , 20°C/68°F. When the paint is applied on zinc silicate coatings, popping may occur after application or after first heating up. To avoid popping it is recommended to follow the procedure: A thin, undiluted coat is applied (the mist coat) and after a few minutes, a second coat is applied in the full specified film thickness as per the data sheet.
