The Polycor Gelfast BS18B25 Dark Admiralty Grey Gelcoat 22kg is a professional-grade pigmented gelcoat designed for extensive fibreglass, marine and composite work where both durability and appearance are priorities. Finished in a rich Dark Admiralty Grey (BS18B25), this gelcoat brings a deep, classic tone to large surfaces such as boat hulls, mould panels, deck sections and structural GRP components.

Supplied in a 22 kg pack size, it offers generous coverage for jobs that require broad area coating with consistent colour - reducing product changes and helping maintain smooth surface transitions across your project. Formulated with isophthalic polyester resin, this gelcoat supports enhanced resistance to moisture uptake and environmental exposure when compared to standard gelcoat systems, helping maintain integrity and colour in demanding conditions.

When mixed with the recommended catalyst and applied over prepared substrates, this gelcoat provides even flow and build, producing a uniform finish with strong pigment dispersion. Whether you’re working on new constructions, major refits, or composite panel fabrication, Polycor Gelfast BS18B25 Dark Admiralty Grey Gelcoat 22kg offers a blend of professional aesthetic appeal and long-lasting surface performance.
