GP Primer – Adhesion-Boosting Primer for Roof Coatings

GP Primer is a high-performance, water-based acrylic primer formulated to improve the adhesion of topcoat systems on roof tiles. Designed for both smooth and rough cement roof tiles, this primer establishes a strong bond between the roof surface and the final coating, providing a consistent foundation for long-lasting durability and aesthetic performance.

What sets GP Primer apart is its dual-action role as both an adhesion promoter and a surface filler. Its high solids content allows it to effectively fill minor surface imperfections, especially on rough cement tiles, helping create a smoother substrate before the application of NuTech’s roof coatings.

When used in conjunction with NuTech’s roof coating systems, GP Primer contributes to a uniform, professional finish that stands up to Australia’s harsh environmental conditions.

⚠️ Note: GP Primer is not suitable for use on oxidised or powdery roof tiles. For these surfaces, NuTech recommends NuPrime for optimal surface preparation.
