COLPHENE Sanded is an SBS-modified bitumen cap ply for use in approved multi-ply membrane waterproofing assemblies. COLPHENE Sanded 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 and underside are surfaced with fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.
Prior to installation, unroll COLPHENE Sanded onto the surface and allow to relax. Position COLPHENE Sanded in desired position and back roll the product. COLPHENE Sanded is then rolled into the cold adhesive or hot asphalt and subsequently broomed in if utilizing hot asphalt or rolled with a weighted roll if utilizing cold adhesives. Subsequent approved inter-ply or cap ply membranes are applied to COLPHENE Sanded via cold adhesive or hot asphalt. Refer to the SOPREMA’s specifications and installation instructions for additional application guidelines.
