GP Primer

General Purpose Primer with filler properties

GP Primer is a water-based acrylic, adhesion promoting general-purpose primer designed to improve the bond between a wide range of roof surfaces including smooth, glossy and rough cement roof tiles.
Due to its high solids content, GP Primer is ideally suited as a filler coat on very rough cement tiles, improving the appearance of all Nutech topcoat systems.

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


  • Promotes inter-coat adhesion
  • High solids to maximise fill characteristics
  • Waterproof
  • Fast drying
  • Easy application
