Perimeter Walls & Inside Corners

Adhere the field sheet to the substrate until the membrane reaches the wall. Apply Bonding Adhesive to the folded membrane and the wall area. Starting at the base or angle change between the corner and opposite end of each wall, begin to roll the EPDM sheet up and along the wall to form a wall flashing. Roll the excess EPDM material towards the corner. Take care to thoroughly adhere the membrane into the angle change before rolling the membrane up the walls. Broom or hand rub the flashings to ensure 100% adhesion.

NOTE: Wall Flashings should extend a minimum of twelve inches (12") above the roof deck (shown in Figure 16).

Figure 16

When one side is flashed in, (A), begin the other side, (B). When both walls are flashed in, all excess material should form a pocket in the corner.

Clean the inside and outside of the pocket with Membrane Cleaner and apply Rubber to Rubber Adhesive to both sides of the pocket. (shown in Figure 17). Allow the adhesive to dry to the finger touch as tacky, not stringy.

Note: It is important to adhere the wall flashing on each side of the corner as tightly into the corner as possible.

Starting at the base of the inside corner pocket, press the two glued surfaces together. Following standard seaming procedures adhere the pocket to either wall (shown in Figure 12). Install a 6" Cured Cover Strip with Tape extending from the bottom of the pocket fold to the top, as shown in Figure 23.
