Blackfriars Red Oxide Metal Primer 2.5L is used as an initial coating on steel and iron surfaces. It is applied before finishing paint to establish an even, stable base suited to various on-site metalwork, including railings, frames, and structural components.
Typically, the primer is used on bare or previously painted ferrous metals by brushing or rolling. Its red oxide formulation helps promote paint adhesion and prepares metal for topcoats during refurbishment or new installation tasks on construction projects.
