Surface Preparation


Recommended Substrate Conditions and Temperatures

Substrate conditions

  • Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
  • Previous coat must be sound, dry and free from any contamination

 

Substrate Temperature & Application Conditions


  • Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

Application


Instructions for Use

Mixing ratio by volume: base to hardener 80:20 (4:1)

  • The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Adding too much thinner results in reduced sag resistance
  • Thinner should be added after mixing the components
