Product Information

Full details

The ClassicBond 150mm Pressure Sensitive Overlayment Cover Strip is designed for professional roofing contractors and DIYers working on EPDM rubber roofing systems. It provides a superior, weather-resistant solution for butt-joining membranes, sealing metal edges, and securing fastening plates, especially when standard 76mm tapes are insufficient. While it offers exceptional durability and ease of application, it strictly requires the use of a compatible primer to ensure a long-lasting, watertight bond.

FAQs

Can I use this tape without primer?

No, using the product without ClassicBond EPDM Primer will significantly compromise the bond strength and is not recommended.

Is this tape suitable for pond liners?

This product is specifically designed for EPDM roofing systems. For pond liners, consult the manufacturer's specific recommendations for underwater-safe adhesives.

What should I use to apply pressure?

A standard silicone hand roller is the best tool to ensure even pressure and proper adhesive activation.

Can this be used on metal surfaces?

Yes, it is specifically designed to seal metal edging and drip edges when properly primed.

How long does the adhesive take to cure?

The adhesive is pressure-sensitive and provides an immediate bond, though full curing occurs over the following 24-48 hours depending on weather conditions.

Troubleshooting

Tape is not sticking correctly to the membrane

Ensure the surface was cleaned properly and that ClassicBond EPDM Primer was applied and allowed to dry until tacky.

Air bubbles forming under the strip

Use a silicone hand roller with firm pressure starting from the center and working outwards toward the edges.

Difficulty cutting to size

Use a sharp, heavy-duty utility knife and change blades frequently to prevent tearing of the EPDM material.

Pros and Cons

Pros

  • Superior width for challenging seam and edge applications
  • High resistance to weathering, tearing, and abrasion
  • Provides a clean, professional aesthetic for roofing details
  • Easy to cut to exact dimensions required for specific tasks

Cons

  • Requires separate purchase of ClassicBond EPDM Primer
  • Surface must be completely clean and dry for effective adhesion
  • Limited to use within the ClassicBond EPDM system for best results

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free of oils or debris. The use of ClassicBond EPDM Primer (302060) is mandatory; apply the primer to both surfaces to be joined and allow it to become tacky. Once primed, peel back the release liner and apply the tape, applying firm, even pressure across the entire surface using a silicone hand roller to activate the pressure-sensitive adhesive. Store the rolls in a cool, dry place away from direct sunlight to maintain adhesive integrity. Always ensure you are working within recommended ambient temperatures to ensure the adhesive cures correctly.
