3.3.3 Membrane Installation

Membrane shall be applied in accordance with the manufacturer's instructions and the following requirements. Layout membrane and side lap adjoining sheets in accordance with membrane manufacturer’s installation instruction. Allow for sufficient membrane to form proper membrane terminations. Remove dusting agents and dirt from membrane and substrate areas where bonding adhesive are to be applied. Apply specified adhesive evenly and continuously to substrate at rates recommended by the roof membrane manufacturer’s application instructions. Do not apply bonding adhesive to surfaces of membrane in seam or lap areas. Allow adhesive to flash off or dry to consistency prescribed by manufacturer before adhering sheets to the substrate, Roll each sheet into adhesive slowly and evenly to avoid wrinkles; broom or roll the membrane to remove air pockets and fish mouths and to ensure full, continuous bonding of sheet to substrate. Form field lap splices or seams as specified.

Allow the adhesive to dry until it is tacky but will not string or stick to a dry finger touch.

3.3.4 Lap Splices
