Cross Coating

Last updated: October 23, 2017

What Does Cross Coating Mean?

A cross coating is a method of applying a protective fluid to a substrate’s surface to prevent corrosion by using successive strokes at right angles relative to each other. Applying protective substances in this manner ensures that no area on the substrate’s surface remains exposed to the threat of infiltration by any hazardous substances.


Corrosionpedia Explains Cross Coating

Cross coating involves the use of paints, pigments, gels, solvents or other substances to prevent the reaction of a metallic surface with corrosion-causing agents such as water, electrolytic compounds or debris.

Cross coating reduces the likelihood of pinholes or holidays in the coating, and also ensures that a successively thicker layer of fluid is applied for prolonged corrosion resistance over time as each layer is subsequently degraded by wear and tear.
