1. Thoroughly clean the surface with Devcon® Cleaner Blend 300 to remove all oil, grease and dirt.
2. Grit blast surface area with 8-40 mesh grit, or grind with a coarse wheel or abrasive disc pad, to create increased
surface area for better adhesion (Caution: An abrasive disc pad can only be used provided white metal is revealed).
Desired profile is 3-5mil, including defined edges (do not "feather-edge” epoxy).
Note: For metals exposed to sea water or other salt solution, grit-blast and high-pressure-water-blast the area, then leave
overnight to allow any salts in the metal to “sweat” to the surface. Repeat blasting to “sweat out” all soluble salts. Perform
chloride contamination test to determine soluble salt content (should be no more than 40ppm).
3. Clean surface again with Devcon® Cleaner Blend 300 to remove all traces of oil, grease, dust or other foreign
substances from the grit blasting.
4. Repair surface as soon as possible to eliminate any changes or surface contaminants.
WORKING CONDITIONS: Ideal application temperature is 55° to 90° In cold working conditions, directly heat repair
