COLPLY® Flashing Cement offers a high-quality, single component viscous formulation, specifically designed for adhering SBS-modified bitumen membrane flashing assemblies. COLPLY roof flashing cement is blended with specially selected and processed asphalt and performance additives. These components give it a smooth troweling consistency, for ease of application to SBS-modified bitumen membranes.

Installation

COLPLY Flashing Cement is applied to approved, compatible substrates using ¼” inch notched neoprene squeegees or trowels. Apply COLPLY Flashing Cement at 2-2.5 gallons per 100 square feet for sand-surfaced 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 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 the SOPREMA® SBS Roofing Manual for additional application guidelines.
