If you need an asphalt cutback adhesive formulated specifically for adhering to SBS-modified bitumen membrane systems, look to SOPREMA COLPLY® Adhesive. COLPLY Adhesive is a high-quality, single-component roofing adhesive formula. COLPLY Adhesive is a specially selected blend of processed asphalt and performance additives, offering smooth troweling consistency.

Installation

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.
