Description

A sag-resistant, rapid-set cementitious render designed for manual and machine application to mineral substrates, both indoors and outdoors. Manufactured in accordance with EN 998-1.

Used for rendering, patching and smoothing wall surfaces. It is manufactured from Portland cement-based premixed dry mortar and general-purpose (GP) rendering mortar of strength class CS IV, containing selected mineral aggregate and special polymers.

Features and benefits:

  • High crystalline water binding properties.
  • Good workability and adhesion.
  • Allows early installation of coverings.
  • Ready to receive ceramic covering after six hours.
  • High sag resistance due to fibre reinforcement.
  • Low-chromate to Regulation (EC) No 1907/ 2006, Annex XVII.
  • CE marked.
