Coverage Guide
Coverage will vary depending on substrate porosity, surface condition, and application technique. As a general guide:
Approximately 2 – 3m² per litre
Surface Preparation Requirements
Always ensure surfaces are clean, dry, and completely free from dust, debris, oil, grease, or other contaminants before application. Proper surface preparation is essential for optimal adhesive performance and long-term bond integrity.
Application Instructions
- Ensure the deck surface is clean, dry, and free from all contaminants
- Apply adhesive evenly to the deck surface using a suitable roller
- Allow the adhesive to become tacky to the touch before membrane placement
- Carefully position the EPDM membrane onto the adhesive-coated surface
- Work from the centre outward to avoid trapping air beneath the membrane
- Apply firm, even pressure across the entire surface to ensure full contact
- Use a roller or hand pressure to eliminate any air pockets and achieve complete adhesion
Professional Installation Advice
For best results, install in dry weather conditions with temperatures above 5°C. Follow standard EPDM roofing installation practices and manufacturer guidelines. Avoid application during rain, high humidity, or freezing conditions.
Typical Applications
Flat roofs
Garden rooms
Extensions
Garages

Frequently Asked Questions
Q: What surfaces is this adhesive suitable for? A: It's formulated to bond EPDM membrane to timber decking substrates such as plywood and OSB boards, providing a strong, durable fixing for flat roof installations.
Q: How is it applied? A: Apply with a roller in an even coat to both the deck and membrane surfaces (contact-bond method), following the technical datasheet for exact open time before bonding.
Q: How much coverage does one container give? A: Coverage varies with deck porosity and application technique, so always check the technical datasheet for exact m² per litre and order slightly more than your calculated area for edges and detailing.
Q: How long does it take to cure? A: As a water-based adhesive, cure time depends on temperature, humidity and airflow - warmer, drier and well-ventilated conditions cure faster. Always allow a full cure before exposing the roof to foot traffic or water.
Q: Is it suitable for DIY installation? A: Yes, it's roller-applied and straightforward to use, making it a good option for confident DIYers as well as professional installers.
Q: What else do I need to complete the installation? A: You'll need your EPDM membrane, edge trims and lap sealant, plus a bonding primer for detail work such as upstands and penetrations.
