ELASTOPHENE ULTRA-STICK is an SBS-modified bitumen, self-adhered base sheet for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE 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 high quality random glass fiber mat. The topside incorporates a unique surface film for promoting superior adhesion of subsequent plies and the underside is surfaced with a protective split back release film that is removed during application.
Prior to installation, unroll ELASTOPHENE ULTRA-STICK onto the roof surface and allow to relax. Place ELASTOPHENE ULTRA-STICK in desired position. Remove one side of the ELASTOPHENE ULTRA-STICK split back release film and use hand pressure to adhere exposed high tack bottom layer. Remove the other half of the ELASTOPHENE 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 ELASTOPHENE ULTRA-STICK via self-adhered or heat welded application. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
