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.
