SOPRALENE ULTRA-STICK is an SBS-modified bitumen, self-adhered base sheet for use in approved multi-ply membrane and flashing assemblies. SOPRALENE ULTRA-STICK is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen in combination with a specially formulated high tack self-adhesive bottom layer and is reinforced with a tough, dimensionally stable non-woven polyester mat. The topside is surfaced with a unique surface film for superior self-adhered application and the underside is surfaced with a protective split back release film that is removed during application.
Prior to installation, unroll SOPRALENE ULTRA-STICK onto the roof surface and allow to relax. Place SOPRALENE ULTRA-STICK in desired position. Remove one side of the SOPRALENE ULTRA-STICK’s split back release film and use hand pressure to adhere exposed high tack bottom layer. Remove the other half of the SOPRALENE ULTRA-STICK’s release film and roll the entire surface of the sheet with a weighted roller. Subsequent approved cap ply membranes are applied to SOPRALENE ULTRA-STICK via self-adhered or heat welded application. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
