CRC Prime It is a single pack penetrating shop primer with high levels of anti-corrosive zinc complexes. It is formulated for the protection of structural steel and iron and can be applied over clean or lightly rusted surfaces. It forms a durable protective coating with a red-oxide finish that does not require immediate overcoating, but can be overcoated at a later stage if desired. Ongoing protection can be achieved through overcoating or simple recoating with CRC Prime It after 3 years, depending on conditions. Protection in extreme conditions may require re-application more frequently -
