COLPLY EF Flashing Cement

Polyether-based adhesive for SBS modified bitumen membranes on flashings and slope surfaces (> 3%).

UNITS PER SKID: 36

COLPLY EF Flashing Cement is a high-performance, odourless, polyether-based adhesive specifically designed for adhering SBS-modified bituminous membranes on vertical flashings and sloped surfaces greater than 3% (3/8 inch per foot). It is part of SOPREMA’s roofing system solutions and is intended for use in waterproofing and roofing applications where strong adhesion and flexibility are required.

COLPLY EF Flashing Cement is used in conjunction with SBS-modified bituminous membranes. It is not compatible with ELASTOCOL 500 primer and should not be used in combination with it. For low-slope surfaces (less than 3%), SOPREMA recommends using COLPLY EF adhesive (not the Flashing Cement version). The system typically includes a base sheet membrane and a cap sheet membrane, which should be installed on the same day to prevent moisture accumulation on sanded surfaces.

This adhesive is ideal for vertical and sloped flashing applications in roofing systems, particularly where SBS-modified bitumen membranes are used. It is suitable for use on sanded surfaces, coverboards, insulation boards, and granulated surfaces. It is not intended for use on flat or low-slope surfaces, where a different adhesive (COLPLY EF) is recommended.

COLPLY EF Flashing Cement should be applied using a notched trowel (4.8 mm [3/16 in] or 6.0 mm [1/4 in]) to ensure a uniform coat. The minimum application temperature is 0 °C (32 °F). Coverage rates vary depending on the substrate:

- Sanded surfaces, coverboard, insulation board, CSP 3: 2.0 to 3.0 US gallons per 100 ft² (0.8 to 1.2 L/m²)

- Granulated surfaces: 3.0 to 4.0 US gallons per 100 ft² (1.2 to 1.6 L/m²)

- Curing Time: Approximately 7 days under ideal conditions (25 °C / 77 °F and 50% relative humidity). Curing time may be longer at lower temperatures or with thicker applications.

- Pot Life: Not specified, but as a single-component adhesive, it remains usable as long as it is stored properly and not cured.

- Storage Conditions: Store in original sealed containers between 5 °C and 40 °C (41 °F to 104 °F), in a ventilated area away from heat and direct sunlight. Shelf life is up to 6 months.

- VOC Content: Very low, at 15 g/L, making it suitable for use in low-emission environments.

- Solids Content: Greater than 99% by weight, ensuring minimal shrinkage and high build.

- UV Resistance: Not specified; typically, flashing adhesives are protected by the membrane and not exposed directly to UV.

- Cleaning: Tools and uncured adhesive can be cleaned with mineral spirits, Varsol, or Xylene.

- Restrictions: Do not use with ELASTOCOL 500 primer. Always consult the latest SOPREMA Roofer’s Guide or a SOPREMA representative for detailed application methods and compatibility.

This material is a key component in SOPREMA’s SBS-modified bitumen roofing systems, particularly for detailing and flashing work on sloped or vertical surfaces.
