Laying Out RUBBERALL® EPDM Membrane

Unroll the RUBBERALL® EPDM membrane over the substrate so that the sheet is in the desired position and is wrinkle free. If more than one sheet of membrane is required always place the first sheet of membrane at the low point on the roof. Subsequent sheets would over lap the prior sheet at least 4" if using seam tape, 6" if using rubber to rubber adhesive, moving up the roof. Care should be taken to insure membrane overhangs perimeter of the roof at least three inches (3").

Allow the RUBBERALL® membrane to relax. Depending on weather conditions, this could take from fifteen (15) to thirty (30) minutes. Use strips of duct tape on upper edge of membrane to keep the membrane from moving.
