Rapid Porcelin Grey S1 Tile Adhesive

A highly polymer modified fast setting grey cement-based powder adhesive designed with increased flexural strength and extended open time for fixing all types of tiles to a variety of building surfaces in internal, external and total immersion locations. The increased polymer level combined with fibres gives reinforced flexural and bond strength in addition to giving the adhesive crack bridging properties up to 3 mm and also an extended pot life to improve workability. The adhesive has excellent thermal ageing properties and is particularly suitable for heated floors and strengthened timber floors. When fixing light coloured or translucent stone a white adhesive such as Norcros Rapid Porcelain and Stone White S1 should be used to avoid staining. A further benefit of the adhesive is its anti-shrinkage properties, making it suitable for a bed thickness up to 10 mm.

Features and benefits:

  • Increased flexural strength.
  • Fibre reinforced.
  • For use with limestone and marble.
  • Crack bridging.
  • Improved coverage.
  • Suitable for use with underfloor heating and plywood overlay.
  • Conforms to BS EN 12004 C2TE S1.
