The Polycor Gelfast RAL7023 Concrete Grey Gelcoat 22kg delivers a modern, neutral grey finish with the performance demanded by professional builders and composite fabricators. Pigmented to the widely recognised RAL7023 Concrete Grey shade, this polyester gelcoat combines attractive appearance with a robust surface texture that works well across marine, industrial and architectural GRP applications.

Supplied in a generous 22 kg pack size, this gelcoat is ideal for extensive surface coating jobs - including boat hulls, decks, mould tooling, structural panels and large composite components. Its isophthalic polyester resin base supports improved resistance to moisture uptake and environmental exposure when compared to standard gelcoat formulas, helping your fibreglass projects stand up to demanding service conditions.

Designed for even flow and smooth build-up, this gelcoat can be applied by brush, roller or spray once mixed with the appropriate catalyst. The balanced pigmentation and uniform texture help minimise surface blemishes and deliver a consistent tonal finish across wider areas.

Whether you’re completing a new build or refinishing large existing surfaces, Polycor Gelfast RAL7023 Concrete Grey Gelcoat 22kg gives you professional-grade colour control and performance in one cohesive formulation.
