  • Surface Preparation

    Remove all contaminants that would impede bond. Use effective cleaning procedures to remove: rust, dirt, oil and grease. This may include the use of high-pressure fresh water cleaning, using suitable solvents or detergents to SSPC-SP 1 or abrasive blast to SSPC-SP 6.

    Application

    • Environment: Use only where application and curing can proceed at temperatures above 40°F (4°C). The temperature of the surface and that of the coating itself must also be within these limits. Apply only on a clean surface. (See detailed Field Specifications for complete instructions.)

    • Mixing: Pour entire contents of hardener container into the resin container and mix thoroughly until homogeneously mixed, approx. 3-5 minutes.

    • Application Method: Apply epoxy by brush or pad.
