EPDM Contact Adhesive | 5L | Perimeter & Upstand Bonding | Heavy Duty

EPDM Contact Adhesive | High-Strength Bonding for Rubber Roofing

Ensure permanent, weatherproof bonds on your EPDM rubber roof installation with this professional-grade 5 litre contact adhesive. Specifically formulated for EPDM roofing membranes, this adhesive creates instant, high-strength bonds at perimeters, upstands, flashings, and all critical detail areas where reliability is essential.

🔧 Specifications

✅ Key Benefits

• Instant High-Strength Bond – Contact surfaces bond immediately when pressed together
• EPDM Compatible – Formulated specifically for EPDM rubber membranes
• Vertical & Overhead Use – Won't sag or slide on upstands and walls
• Weather Resistant – Maintains bond in rain, frost, heat, and UV exposure
• Professional Results – Same adhesive used by roofing contractors
• Long Open Time – 15-30 minutes to position correctly before bonding
• Flexible When Cured – Moves with membrane without cracking

🏠 Where to Use

• Perimeters – Bond membrane to edge trims (drip, kerb, verge)
• Wall Upstands – Secure membrane up walls and parapets
• Flashings – Attach wall flashing and detail trims
• Corner Pieces – Bond pre-formed corners to membrane
• Overlaps – Seal membrane-to-membrane seams (with seam tape)
• Roof Penetrations – Around pipes, vents, and other protrusions

📦 Coverage Calculator

This 5L tin covers approximately 6-8 linear metres when applied to both surfaces (double coverage). Calculate your requirements:

Note: Add extra for wall upstands, flashings, and detail work. Always have spare adhesive available.

🛠️ Application Guide

1. Prepare Surfaces – Clean and dry both surfaces. Remove dust, oil, and loose material.
2. Apply to Both Surfaces – Use brush or roller to apply even coat to BOTH membrane and substrate.
3. Allow to Tack Off – Wait 15-30 minutes until adhesive is touch-dry (won't transfer to finger).
4. Test Readiness – Touch lightly – should feel tacky but not wet.
5. Position Carefully – Once surfaces contact, repositioning is very difficult.
6. Press Firmly – Apply pressure across entire bonded area.
7. Roll Seams – Use seam roller for uniform pressure, especially at edges.

⚠️ Important Application Notes

• Temperature – Do not apply below +5°C or above +35°C
• Dry Conditions – Both surfaces must be completely dry
• Ventilation – Solvent-based; work in well-ventilated areas
• PPE – Wear gloves and eye protection; consider mask outdoors
• Open Time – Don't rush; adhesive must be touch-dry before bonding
• No Repositioning – Bond is instant; align carefully before contact

💬 Frequently Asked Questions

Q: Can I use this for full roof coverage or just perimeters?
A: This contact adhesive is designed for perimeters, details, and vertical surfaces. For full adhered systems, use water-based bonding adhesive (applied to deck only) which is more economical for large areas.

Q: What's the difference between contact adhesive and bonding adhesive?
A: Contact adhesive creates instant bond when two coated surfaces touch – ideal for details and verticals. Bonding adhesive is applied to the deck only, allowing positioning before membrane contact.

Q: How long until I can walk on bonded areas?
A: Once bonded, you can walk on the roof immediately. Full cure takes 24-48 hours.

Q: Will this work in cold weather?
A: Do not apply below +5°C. In cold weather, adhesive may need longer to tack off and won't cure properly below freezing.

Q: Can I use this with TPO or PVC membranes?
A: This adhesive is formulated for EPDM. For TPO/PVC, use a compatible adhesive specifically designed for those materials.
