FAQs – Cure-It GRP C3 Wall Fillet Corner

Can I use the C3 corner fillet with other GRP systems?

It’s specifically designed for the Cure-It GRP roofing system, so compatibility with other systems can’t be guaranteed. For best results, use it as part of a full Cure-It installation.

Do I need to apply resin over the C3 corner during installation?

Yes, the C3 corner should be laminated into the roofing system using resin and matting, just like other GRP components. This ensures a fully bonded, watertight seal.
