Description

Unifiber is a high-performance fibreglass primer designed for direct application onto GRP/FRP surfaces, providing a strong, reliable foundation for yacht coatings. Ideal for professional boat owners and refit projects, this primer ensures excellent adhesion at low thickness, making it perfect for one-component systems while saving material and time.

Its versatile formulation also allows Unifiber to be used as an intermediate tie coat between epoxy primers and two-component finishes, creating a seamless transition in multi-layer coating systems. Suitable for both above and below the waterline, Unifiber ensures your vessel maintains a durable, long-lasting protective finish, whether over epoxy systems, Topkapi enamel or antifouling coatings.

Fast-drying and easy to apply by brush, roller, or spray, Unifiber provides a smooth, consistent surface that enhances topcoat performance, adhesion, and overall durability. Its robust marine-grade formulation is engineered to withstand the harshest marine environments, including UV exposure, saltwater, and temperature variations, giving professionals and DIY boat owners confidence in every application.

With Unifiber fibreglass primer, you can achieve a strong, reliable, and long-lasting foundation for all your yacht coating systems, optimizing adhesion, reducing the risk of peeling, and ensuring a flawless finish for your topcoats.
