Application Instructions

Surface Preparation:

New Steel - Surface must be dry and free of contamination. Remove all weld spatter and grind all rough welds and edges to smooth contour.

Previously Painted Surfaces - Must be free of oil, grease, or other contamination. For best results, spot blast exposed areas to be primed. Power tool brushing may be used for minor touch up.


Thoroughly mix coating prior to applying to substrate. Surface shall be dry, above 60° F and 5° above the dew point, and free of rust bloom. Double lap all welds, seams, corners, and edges to insure proper thickness. Make even parallel passes with 50% overlap to provide uniformity.
This product has been formulated to be used at full strength. If reduction is required, water should be used.
