Product Properties

  • Overlying Material SBS Membrane


COLPLY Adhesive is applied to approved, compatible substrates using ¼” inch notched neoprene squeegees or trowels. Apply COLPLY Adhesive at 1.5 to 2 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 3 to 4 gallons per 100 square feet. 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.
