Before removing release liner, fold the flashing lengthwise about 1" to 1-1/2" (2.5 cm to 3.8 cm) from the edge, to form a crease. Next, fold 3/8" to 3/4" (1 cm to 1.9 cm) of material back up to form a second crease. The peak that is formed will serve as the backdam, thus providing positive water drainage to the exterior. c.
