Recommended Substrate Conditions and Temperatures

Substrate conditions

• Steel; blast cleaned to a minimum of SSPC-SP10 or ISO-SA2½ , blasting profile 50 – 125 µm (5.0 mils) (2.0 – 5.0 mils)
• Steel with suitable primer (NOVAGUARD 260 or PHENGUARD 930) must be dry and free from any contamination

Substrate temperature

• Substrate temperature during application and curing should be above 10°C (50°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

Instructions For Use

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

• The temperature of the mixed base and hardener should preferably be at least 20°C (68°F)
• No thinner should be added
• For recommended application instructions, see working procedure
• At lower temperature, the viscosity will be too high for spray application

Airless spray

Recommended thinner

No thinner should be added
