COLPLY® EF Flashing Cement is a high performance, single-component viscous cement for use with SBS-modified bitumen membrane flashing assemblies. Due to its polymer composition, once cured, COLPLY EF Adhesive provides an additional layer of elastomeric waterproofing protection beneath or between membrane plies. COLPLY EF (environmentally friendly) Flashing Cement is unique in that it is a solvent-free and ultra-low VOC material allowing for application flexibility on job sites where exposure to VOCs or odor may be a concern.

Product Properties

  • Overlying Material SBS Membrane


COLPLY EF Flashing Cement is applied to approved, compatible substrates using ¼ inch notched neoprene squeegees or trowels. Apply COLPLY EF Flashing Cement at 2 to 2.5 gallons per 100 square feet for sandsurfaced interply applications. The application rate over approved absorptive or rough substrate surfaces vary, requiring 2.5 gallons or more per 100 square feet. Specifically granulated surfaces require 4 to 5 gallons per 100 square feet. COLPLY EF Flashing Cement is applied to both the flashing ply and the substrate prior to placement of the flashing ply. 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 SOPREMA® SBS Roofing Manual for additional application guidelines.
