ULTRA-STICK Nail Base is an SBS-modified bitumen nail base sheet for use in approved multi-ply membrane assemblies over nailable deck. ULTRA-STICK Nail Base is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen 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 fine mineral aggregate.

Installation

Prior to installation, unroll ULTRA-STICK Nail Base onto the roof surface and allow to relax. Place ULTRA-STICK Nail Base in desired position. ULTRA-STICK Nail Base is then mechanically fastened to the approved substrate following the fastening pattern required for proper uplift. Subsequent approved base plies are applied to ULTRA-STICK Nail Base via self-adhered application. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
