GP Primer

Introducing GP Primer: Enhancing Bond and Appearance for Roof Surfaces.

GP Primer is a water-based acrylic primer specifically developed to enhance the adhesion between roof surfaces. Whether dealing with smooth, glossy, or rough cement roof tiles, GP Primer is designed to improve the bond, ensuring a reliable foundation for subsequent coating applications. Its adhesion-promoting properties make it an ideal choice for achieving optimal results.

One of the standout features of GP Primer is its filler properties. With a high solids content, this primer serves as a filler coat, particularly effective on rough cement tiles. By utilizing GP Primer as a filler, you can significantly improve the appearance of the surface, setting the stage for the flawless application of Nutech’s topcoat systems. With the combined power of GP Primer and Nutech’s topcoat products, achieve a smooth and visually appealing finish.

GP Primer is not recommended for oxidised and powdery tiles. Instead, use NuPrime.
