| Basic Use | A water reducible corrosion resistant coating for priming all exterior or interior ferrous metal surfaces such as structural steel, bridges, tanks, towers, piping, sash and trim metal doors and frames, ornamental iron, gutters & misc metal objects. It is flash rust resistant and possesses the rust-resistant and film forming properties typically associated with standard solvent-borne type primers. Metal Master resists attack by many caustic solutions, light industrial fumes and chemicals. Has excellent adhesion and the fast dry capabilities of a dryfall finish. |

Prep & Prime
*All substrates must be clean & dry prior to application* Remove all rust, dirt, grease, cutting oil, & all other contaminants that could interfere with adhesion of the coating per SSPC SP1. Glossy, glazed or shiny surfaces should be abraded using SSPC-SP2 or SP3 methods for moderate environments. For maximum performance, blast cleaning metal to a SSPC-SP6 Commercial Blast Standard is recommended to improve service life of the coating.
When priming factory finished siding such as Kynar, fluorocarbon, or baked polyester polymers the adhesion must be confirmed using test patches. Allow test patches one week of dry time before testing adhesion to ensure proper cure. Confirm using ASTM 3359 Method A X-Cut Tape Test method with results of 4A to 5A prior to proceeding with application. Contact your Rodda Paint representative with any question.
