1 WORK INCLUDED

(1) Suitable field substrate: May be the roof deck or deck overlay (if an uninsulated system), or insulation and an overlay (if conventionally insulated).
(2) Primer or adhesive: For self-adhered or adhered membranes, as required by the manufacturer.
(3) Base field membrane: Carried continuously over the outside edge at least 50.8 mm (2”) downward, or 50.8 mm past any cold joint.
(4) Sealant or mastic: Applied on membrane, beneath metal edge flashing.
(5) Metal edge flashing (flush with roof surface):: Fasteners spaced no more than 203.2 mm (8”) on the top face in two offsetting rows.; A hemmed drip edge (shown) is required (Refer to Article 13.2.2.1. for fabrication requirements).
(6) Membrane flashing strip: Applied to the metal edge flashing and overlapping onto the field membrane at least 101.6 mm (4”). Prime when required by the manufacturer (primer illustrated).
(7) Cap field membrane: Installed according to Part 9 requirements.
(8) Edge mastic: Apply mastic or another membrane-compatible sealant to the outer exposed edge of the field cap sheet membrane. Coat with granules.
