Corrosionpedia explains Overspray Blend
Overspray blending is typically required when structures with complex geometries and configurations have been painted or sprayed with a coating. This is due to the inherent difficulty of obtaining a uniform coating in such instances. Overspray blending is required because fine dust particles can become trapped in the coating and between successive coating layers that may be applied.
