Teknocem HB50

For the structural repair, rendering and profiling of vertical, horizontal and overhead surfaces.


Single component cementitious mortar which incorporates the most advanced cement chemistry, microsilica, fibre and styrene acrylic copolymer technology. This results in a rapid hardening, low density, high strength mortar with enhanced polymer properties. The thixotropic nature of the product enables easy high build trowel application. It is supplied as a single component system ready for on-site mixing and use, requiring only the addition of clean water.

Features/ Benefits:

  • Pre-packaged material requiring mixing with clean water on-site to give an easily trowellable mortar with application thickness of 80 mm in vertical, horizontal and overhead situations.
  • High bond strength exceeds tensile strength of concrete, thus ensuring monolithic performance of the repair.
  • Dense matrix offers low permeability to water, even at 10 bar pressure, and very high diffusion resistance to acid gases and chloride ions.
  • Improved tensile and impact strength.
  • Excellent low sag properties.
  • Economic mortar generally requiring no substrate or inter-layer priming. Part bags can be mixed.
  • Easily over-coated with specialist membranes to provide further protection and aesthetic quality.


For the structural repair, rendering and profiling of vertical, horizontal and overhead surfaces.


Highly porous substrates should be primed with Teknoprime 842.
