    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.

    Spray:

    • 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.
