Over Coating Procedure:
Zinc rich coatings are porous and hence pinholes may occur in the subsequent coat due to solvent popping. To minimize pinholes, apply a mist coat as the first pass of the subsequent coat, let the entrapped air escape and then apply full coat. Zinc rich primers, when exposed for extended periods of time without proper top coating, will start showing white rust formation. These “white rust” spots are zinc corrosion products. The extent of white rust formation will depend on the period of exposure of the zinc rich coating and the nature of the surrounding environment. Prior to application of the subsequent coats, it is necessary to ensure removal of the white rust.
