EZ On Coat EPDM Cleaner/Primer is a low viscosity sprayable liquid used to pre-treat an EPDM rubber roof membrane prior to power washing and application of the roof coating. Promotes adhesion of the elastomeric coating applied to the EPDM surface. Contact EZ On Coat for clarification of unusual surfaces or project conditions. USES Improves adhesion to EPDM for longer roof protection. APPLICATION Surface Preparation Application Existing roof systems to be visually inspected for conditions that may adversely affect performance of adhesion of newly installed products. Repair any visible deficiencies such as splitting, blistering, and buckling. Visually inspect all metal and non-metal flashings, edges, drains, valleys, and through-roof penetrations and repair as needed by project conditions. Stir well prior to application. Apply EZ On Coat EPDM Cleaner/Primer via a sprayer (Hudson-type agricultural, conventional pressure, or airless) at an application rate of 500 square feet/gallon using a 3-4 foot arc pattern. Allow EZ On Coat EPDM Cleaner/Primer to stand for a minimum of 15 minutes. Agitate the EPDM Cleaner/Primer with a broom. Rinse the EPDM with a commercial power washer (between 2,000-3,500 psi). When rinsing the EPDM, it should be done slowly and in close proximity to surface in order to remove mica and inorganic release agents. Execute a secondary rinse thoroughly with power washer. The rinse step may be done at a faster pace than the cleaning step. The final rinse water should be clear with no soap bubbles present. The EPDM will range from muddy brown to black after washing with EZ On Coat EPDM Cleaner/Primer. When the surface is dry, coating can begin. Do not thin product. Do NOT rinse off onto concrete. It WILL stain
