Installation
1. Apply P 1.2 EPDM Rinseable Primer via a sprayer (Hudson-type agricultural, conventional pressure or airless) at an application rate of 500 sq ft/gal. If sprayer is not available, roll applying primer is acceptable.

3. Allow P 1.2 EPDM Rinseable Primer to stand for a minimum of 15 minutes.
4. Clean EPDM with a commercial power washer (between 2,000-3,500 psi). When cleaning the EPDM, it should be done slowly and close to the surface in order to remove mica and inorganic release agents.

6.When the surface is dry, coating can begin.
