GP Primer

General Purpose Primer with filler properties

Roof tile with rough uneven surface

GP Primer is a general purpose primer designed to adhere to a wide range of roof surfaces including smooth, glossy and rough cement roof tiles. Formulated from high quality adhesion promoted acrylic resins GP Primer is ideally suited as a filler coat on very rough cement tiles because of its high solids content, improving the gloss appearance and coverage of all Nutech topcoat systems.

GP Primer is not recommended for Oxidised and Powdery Tiles (refer NuPrime).

Suitable Substrates

GP Primer is recommended as an undercoat: Cement tiles – Painted surfaces – New tiles. GP Primer is a high solids adhesion undercoat recommended for NuFlex, TileFlex and Colourfast topcoat systems. It is a Low Sheen water based coating with excellent durability and adhesion performance.

Surfaces primed with GP Primer and top coated with a 100% Acrylic systems perform exceptionally providing years of maintenance free service. This product is Non-toxic, Non-flammable and faster drying year round making application safer and easier. On smooth surfaces the additional coverage of a topcoat is increased improving economy.

GP Primer has been developed following years of research and development to formulate an undercoat, which will adhere to a range of roofing surfaces and enhance the appearance of topcoat systems.

GP Primer has been developed for Australian and South-East Asian environmental conditions. It provides excellent protection against biological growth including Moss, Lichen, Mould and Fungus.
