What color is used for the first coat primer on ships?

The first coat primer on ships is typically identified by a specific color, which serves both protective and functional purposes. In the context of maritime painting practices, the first coat primer is often colored green. This green primer is formulated to provide a solid base for subsequent paint layers, improve adhesion, and offer corrosion resistance to the metal surfaces of the ship.

Using a specific color for primer, such as green, also helps crew members and workers to easily recognize areas that have been primed versus those that still require attention. It acts as a visual cue during inspections and maintenance, ensuring that all surfaces are adequately prepared for topcoats and that no areas are overlooked. Additionally, the pigments used in green primer contribute to its efficiency in mitigating the damaging effects of saltwater and other environmental factors present in marine settings.
