• If the basecoat is allowed to get wet, it is likely to be damaged – blistering and wrinkling may occur.
• SC802 should only be applied when the air and steel temperatures are above 5°C. Relative humidity should be below 80% for successful application. Steel surface temperature should be a minimum of 3°C above the dew point.
• Ensure the steel is dry and free from contact with rain or condensation during the application and drying of SC802.
