Primary Applications
Membrane to Deck Bonding
Secure EPDM rubber membranes directly to timber, OSB or plywood roof decking for fully adhered installations
Insulation Board Adhesion
Bond EPDM membranes to rigid insulation boards in warm roof and inverted roof configurations
Vertical Upstand Detailing
Adhere EPDM to vertical surfaces including parapet walls, abutments and penetration upstands
Perimeter Edge Work
Secure membrane edges, termination bars and perimeter details for watertight edge sealing
Installation Guidelines
Surface Preparation
Ensure all substrates are clean, dry, dust-free and structurally sound before application. Remove any loose material, oil, grease or contaminants. Prime porous substrates if required.
Application Process
- Apply adhesive evenly to both the substrate and the back of the EPDM membrane using a short-pile roller
- Allow adhesive to become touch-dry (typically 10-20 minutes depending on temperature and humidity)
- Carefully position the membrane and press firmly into contact, working from one edge to eliminate air pockets
- Apply firm, even pressure across the entire bonded area using a roller or hand pressure
- Bond is immediate upon contact and cannot be repositioned
Working Conditions
| Ambient Temperature | Apply between 5°C and 30°C for optimal performance |
| Substrate Condition | Must be completely dry and frost-free |
| Weather Conditions | Do not apply in rain, high winds or when rain is imminent |
| Ventilation | Ensure adequate ventilation during application and curing |
Ideal Project Types
- Flat roof installations
- Garden room roofing
- Extension flat roofs
- Garage roof systems
- Shed and outbuilding roofs
- Dormer roof construction
- Commercial flat roofing
- Balcony waterproofing
Performance Benefits
Immediate Bond Strength
Contact adhesive technology creates an instant, permanent bond the moment surfaces meet, eliminating curing delays and accelerating project completion.
Exceptional Substrate Versatility
Engineered to bond reliably across timber, engineered wood products, rigid insulation and prepared masonry surfaces without substrate-specific formulations.
Vertical Surface Performance
High-tack formulation maintains secure adhesion on vertical upstands, parapet walls and detail work where gravity challenges conventional adhesives.
Long-Term Durability
Once cured beneath the membrane, the adhesive bond withstands decades of thermal cycling, moisture exposure and structural movement without degradation.
Professional Installation Note
This is a professional-grade adhesive requiring proper surface preparation, correct application technique and appropriate safety precautions. Always read the technical data sheet and safety information before use. Ensure adequate ventilation during application and follow all manufacturer guidelines for optimal performance.
