The Cure It One 20m² GRP Fibreglass Roofing Kit is a high-performance, trade-grade one-coat roofing system engineered for exceptional installation speed and long-term weatherproofing. This innovative, multi-surface direct-lay formula eliminates the need for traditional multi-stage GRP resins and topcoats, operating as a true one-tin, one-solution system. For experienced GRP contractors, the application is completely intuitive while cutting labour time in half—allowing you to install 1m² in less than two minutes.
Formulated for reliable performance, this kit creates a highly flexible, tough, and seamless single-ply laminate bond over a 20-square-metre flat roof area. It is ideal for small domestic extensions, porches, outbuildings, single garage roof replacements, and warm roof installations. The cured system is fully fire retardant to BS476-3 Ext.F.AB standards, meaning it carries absolutely no restrictions on its use across the UK.
Substrate & Surface Compatibility
Cure It One delivers a high-strength bond directly to the substrate with no primer required on:
  • OSB3 Timber Decking
  • Existing GRP Surfaces
  • PIR Insulation Boards (Warm Roof Systems)
  • Bituminous Roofing Felt
  • Note: Porous or volatile surfaces like Concrete and Asphalt can also be overlaid but require a specialist primer beforehand. Cold weather applications may require a Low Temp Cure It One Accelerator / Additive.
