Abstract

A method of installing a roof system, the method comprising (i) providing a first membrane panel including a polymeric planar body having a top planar surface and a bottom planar surface; (ii) securing the first membrane panel to a roof substrate; (iii) providing a second membrane panel including a polymeric planar body having a top planar surface and a bottom planar surface; (iv) positioning the second membrane panel adjacent to the first membrane panel so that the second membrane panel overlaps the first membrane panel in a lap region; (v) applying a primer composition to the top planar surface of the first membrane panel in the lap region to form a first primed surface; (vi) optionally applying a primer composition to the bottom planar surface of the second membrane panel in the lap region to form a second primed surface; (vii) applying an adhesive to at least one of the first primed surface or the second primed surface; and (viii) seaming the first membrane panel to the second membrane panel with the adhesive, where the primer composition applied to the first membrane panel and the primer composition optionally applied to the second membrane panel includes a silyl-terminated polymer.
