Surface Preparation

Remove all dirt, grease, oil, loose rust, scale or other surface contaminants from the substrate. On ferrous substrates, SSPC 6 Commercial Blasting will enhance the performance of the coating system. If sanding is the preferred method of surface preparation, 100-120 grit paper is recommended to create a surface profile for better adhesion. On aluminum substrates sandblasting, or a suitable etch primer will enhance the performance properties of the primer.

Mixing Instructions

Mix 1:1 by volume Base/Cure. We recommend using a squirrel mixer or equivalent and mix thoroughly for 5 minutes minimum. Allow 15-30 minutes induction time before using. Mix only sufficient material to use within a 8-hour period. Always add Cure component to Base component - NEVER THE REVERSE. Never mix coating or individual component from one vendor with that of another vendor.
