Overhead tank painting involves applying protective and decorative coatings to water storage tanks located above ground. This process typically includes surface preparation, such as cleaning and rust removal, followed by the application of primer and specialized paints that resist corrosion and weather elements.

The purpose of overhead tank painting is to enhance aesthetics, ensure durability, and prevent contamination of the stored water. It often involves safety measures due to the height of the tanks, requiring scaffolding or harnesses for workers. Overall, it plays a crucial role in maintaining the integrity and appearance of water storage systems.
