SOPREMA COLPLY® EF (environmentally friendly) Adhesive is solvent-free, ultra-low VOC, designed for use with SBS-modified bitumen membrane systems. COLPLY EF Adhesive offers application flexibility on job sites where exposure to VOC’s or odor may be a concern. Due to its polymer composition, once cured, this high-performance, single-component polymeric roofing adhesive provides an additional layer of elastomeric waterproofing protection beneath or between membrane plies.

Installation

COLPLY EF Adhesive is applied to approved, compatible substrates using ¼” inch notched neoprene squeegees or trowels. Apply COLPLY EF Adhesive at 1.5 to 2 gallons per 100 square feet for sand-surfaced interply applications. When the ambient temperature is below 50°F (10°C), material should be warmed to a temperature of 70°F (24°C) at the time of application. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
