20.0 to 50.0 mils (500 to 1,270 microns), one coat with multiple passes. Note: Series 335 can be applied to an optional high build thickness of 60.0 mils in a single coat to horizontal surfaces.

Primers

Self-priming or Series 61, N69F, 161. Note: For surfaces with light to moderate pitting, priming the surface prior to the Series 335 application may help to prevent holidays in the cured film. Note: The following maximum recoat times apply when topcoating with Series 335; 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.
