Recommended Substrate Conditions:
Steel: Blast cleaned to a minimum grade SSPC-SP10 (SA2 ) The surface must be perfectly dry.

Instructions for Use:
Power agitate base component to uniform consistency before combining, then again after combining. Do Not vary proportions.

Substrate Temperature:
during application and the first 24 hours of curing, the substrate temperature must be above 41F (5C) and at least 5F ( 3C) above the dew point.

Mixing Instructions:
Ratio: base to hardener 4:1 by volume

The temperature of the mixture of base and hardener during mixing and application should be above 59 F (15C), otherwise more solvents must be used to obtain application viscosity. This results in lower sag resistance and slower cure. Thinner should be added after mixing the components.

Very good mechanical mixing of base and hardener is essential in view of the paste consistency.
