Trade Line Dark Grey Topcoat 5kg

Trade Line Dark Grey Topcoat 5kg is a smaller-quantity pack of the Trade Line GRP roofing topcoat, providing a weather-resistant, UV-stable finish to the cured Trade Line resin laminate. It is the final layer of the Trade Line roofing system, giving the roof its protective surface and dark grey appearance.

A practical starter size for small repairs, one-off jobs, and anyone trying the Trade Line range for the first time. This 5kg tin contains a preaccelerated, low-viscosity dark grey polyester topcoat, ready to brush straight on with good levelling and sag resistance. It cures fully tack-free thanks to its wax content, leaving a durable, attractive grey finish over cured laminate. Apply at a wet film thickness of around 500 microns (400–600 micron range) at a minimum temperature of 18°C, mixing in MEKP catalyst at 1.2–3.0% w/w. Don't forget to add your free catalyst at checkout.

Applied once the resin laminate has fully cured, the topcoat bonds to the laminate surface and provides long-term weather, UV, and thermal resistance. Catalyst is included. Coverage is approximately 500-600g per m². For larger area coverage, see the 20kg pack. Always use in conjunction with Trade Line Polyester Resin for a complete system. For fire-rated alternatives, see the SilverSeel or Metrodeck topcoat ranges. Order online today with fast delivery from CFS Fibreglass.
