Topcoat White
Topcoat White is a high-quality, isophthalic, Lloyd’s Approved polyester topcoat designed to seal and protect GRP fibreglass surfaces with a tough, durable and weather-resistant finish.
Unlike standard gelcoat, this Topcoat cures tack-free, allowing it to be applied like a paint while forming a hard, protective surface. It offers excellent water resistance and UV stability, making it suitable for both fibreglass roofing systems and marine applications, including boat building and repairs.
Pre-pigmented in White, this marine-grade topcoat delivers a clean, professional finish and is ideal for a wide range of GRP applications.
Not suitable for spray application.
Catalyst is supplied FREE with all Topcoats and Resins.
