Product Information

Full details

The ClassicBond EPDM Check Kerb External Corner (MPN: 910003) is an essential component for professional roofers and DIY installers looking to achieve a secure, watertight finish on EPDM roofing systems. This pre-formed corner is specifically designed for check kerb systems, eliminating the need for complex cutting or fabrication at corner joints. While it significantly speeds up the installation process and enhances durability, users should ensure they are using the correct EPDM bonding adhesives and lap sealants to guarantee long-term integrity.

FAQs

Can I use this on non-ClassicBond systems?

While it is designed for ClassicBond systems, it may be compatible with other EPDM brands; however, compatibility with specific adhesives should be verified.

Do I need special tools to install this?

No special tools are required, though a professional silicone seam roller is highly recommended for achieving a strong, bubble-free bond.

Is this component flexible?

Yes, it is made of EPDM rubber, which offers excellent flexibility to accommodate building movement without cracking.

What is the expected lifespan of the corner component?

When installed correctly with the appropriate adhesives, it is designed to last as long as the EPDM membrane itself, which can exceed 50 years.

Can I paint over the corner component?

EPDM is not designed to be painted. It is intended to be left in its natural rubber state for optimal weather resistance.

Troubleshooting

The corner piece does not seem to bond correctly

Ensure the surface is properly cleaned with EPDM surface cleaner and that the adhesive was applied to both surfaces and allowed to become tacky.

Water pooling around the corner area

Check that the check kerb system has proper drainage and that the corner component is not obstructing the flow of water away from the roof.

Sealant peeling away from the edges

Re-clean the area with a solvent-based cleaner and re-apply a fresh bead of lap sealant, ensuring the surface is dry before application.

Pros and Cons

Setup, Compatibility & Care

To install the component, ensure the EPDM membrane is clean, dry, and free of dust or oils. Apply the manufacturer-recommended contact adhesive to both the back of the corner piece and the corresponding roofing surface. Position the component carefully, press firmly into place, and use a silicone roller to ensure total contact and remove any air pockets. Finally, apply a bead of EPDM lap sealant around the edges of the component to create an extra layer of protection against water ingress. Regular maintenance involves periodic inspections of the sealants and perimeter edges to ensure no physical damage has occurred due to heavy debris or extreme weather impacts.
