EPDM rubber is a type of rubber sheeting that is manufactured for installation on roofs. It is made form the chemicals ethylene and propylene and can be laid down over existing roofs or used as new roofing over felt or tar paper. EPDM is very durable and resistant to UV rays, and can last 40 years or more if it is applied correctly. It can also be painted using standard painting tools and latex paint.
Apply EPDM correctly for the application that it will be used for. It must be put down first before being painted.
Pressure wash the entire surface to be painted with a pressure washer and detergent. Both of these can be rented from hardware stores. Rinse and allow to dry.
Mix up any type of latex paint in any colour desired, although lighter colours that reflect heat are preferred.
Paint EPDM with latex paint using a standard paint roller and paint tray, just like you would when painting a wall. Brush latex paint into hard-to-reach areas and allow all of the paint to dry before walking on it.
Clean up all painting tools with soap and water.
