16.0 to 40.0 mils (400 to 1015 microns) in one or two coats. Note: For steel surfaces with pitting, recommended DFT is 30 to 40 mils (760 to 1015 microns). Note: Depending on the degree of pitting, a prime coat of Series 61 or resurfacing with Series 215 may help alleviate the potential for holidays in the cured film.

Note: These cure times are based on 20.0 mil (500 micron) dry film thickness. Cure time varies with surface temperature, air movement, humidity, and film thickness. Ventilation: When used as a tank lining or in enclosed areas, provide adequate ventilation during application and cure.
Self-priming or Series 61, N69F, 161. Note: For surfaces with light to moderate pitting, priming the surface prior to the Series 322 application may help to prevent holidays in the cured film. Note: The following maximum recoat times apply when topcoating with Series 322; Series 61, 14 days; Series N69F and 161, 30 days. If this time limit is exceeded, or if Series N69F or 161 is exterior exposed more than 14 days, the primer must be uniformly scarified prior to topcoating. Note: Series N69F or 161 are for crude oil service only.
