EPDM Rubber Roofs


EPDM rubber roofs are fairly inexpensive, long lasting, and don’t require annual care like most roofing materials. However, with the proper coating, your EPDM rubber roof can last a lot longer than other rubber roofs. Ames roof coating helps defend your roof from the outdoor forces while allowing your rubber to be waterproof and energy efficient. With the use of our Rubber Roof products including our Super Primer, adhesive contouring seam tape, Elasto Barrier waterproof base coat and Maximum Stretch rubber coating, you’ll be able to repair, restore and protect your rubber roof. Please contact us for any more information you may need about our products and how they can help you with your EPDM rubber roof.

4. Detailed Application Instructions

Products can be applied with a paint brush, a push broom, a low nap roller with a long handle or a Commercial Airless Sprayer.  In addition, will need Ames® Peel & Stick Seam Tape and scissors or a utility knife.  For larger commercial jobs.  We recommend an airless sprayer with a 3/8 inch, 150 foot hose.  Graco, Bulldog or Titan work well.  Call for sprayer information or check product specifications.   

Power wash the surface to remove all dirt and debris and be sure it is completely dry before the coating application. Read all label instructions before beginning. Always run a test patch first in an inconspicuous area, to ensure that proper adhesion and drying occurs and the product works to your satisfaction.

Apply Ames’® Super Primer™ liberally with a pour out and paint on rate of one to two gallons per 200 square feet. Once the Super primer is dry to the touch apply Ames’® PS250  peel off and stick Seam tape to rips, tears, abrasions joints, over flashing, around vents, around skylights and where two unlike surfaces meet. Next apply two coats of Ames Super Elasto-Barrier™. Pour the thick liquid coating out and spread two gallons of product liberally with a push broom or roller. Work the product until it is smooth and looks consistent in thickness. Move on after a few minutes so the product does not skin over or form a film which can create an unintended texture in the coating’s finished appearance.  Finish the application with two coats of Ames’® Maximum-Stretch™ at the rate of two gallons per 100 square feet for a highly reflective energy saving roof system.

For Reflective and Maintenance Coating Applications Only:
For preventative maintenance only on roofs that drain well -  prime first with Ames® Super Primer then cover with two coats of Ames’® Maximum-Stretch™.  It’s simple, just pour it out and paint it on. Two gallons per 100 square feet seals, stretches, lasts a long time and reflects up to 98% of the UV heat that hits it. Ames’® Maximum-Stretch™ is quality rubber and acrylic that lasts a long time.
