Sika Chapdur Extra is a one-component, pre-mixed, dry, mineral hardener for concrete, consisting of cement, hard aggregates, specially selected quartz aggregates, admixtures and pigments.


Sika Chapdur Extra is intended for use by experienced contractors.

  • Sika Chapdur Extra is a hard-wearing, non-metallic dry mix for monolithic floors. Sprinkled and troweled on a freshly damp concrete floor, it creates a smooth, wear-resistant surface.
  • Typical use in warehouses, production plants, shopping malls, public facilities, restaurants and museums.


  • Good wear resistance rating
  • Impact resistance
  • Cost effective surface hardener
  • Dust protection
  • Easy to clean
  • Increases resistance to oils and greases
  • Factory-prepared mix for consistent, high quality


  • Chemical Base: A mixture of natural and synthetic aggregates mixed with cement, admixtures and pigments.
  • Appearance / Color: Gray powder
  • Density: ~ 2.3 ± 0.05 kg/dm3 (density of bound material)


  • Abrasion resistance: ~46 µm (BCA), class AR 0.5
  • Compressive strength: ≥ 70 MPa (after 28 days)
  • Flexural strength: ≥ 7.0 MPa (after 28 days)
  • Reaction to fire: A1fl


  • Wear: ~3.0-5.0 kg/m2. The given value does not take into account the profile of the substrate and material losses.
  • Ambient temperature: Minimum +5°C / Maximum +35°C
  • Substrate temperature: Minimum +5°C / Maximum +35°C
  • Waiting Time / Overcoating: The application time of dry mix products depends on many variables that result from the concrete placement process and can therefore vary significantly depending on the prevailing conditions. When mechanically applied with an automatic paver and laser screed, the spreading of the material can start almost immediately after the concrete is leveled to allow for the hydration of the dry mix. Compaction with trowels can begin as soon as the concrete has reached sufficient strength to hold the weight of the trowels on its surface.

    When applied by hand, the dry sprinkles must be spread as soon as the concrete can be stepped on, without leaving traces deeper than 3 - 5 mm.

    Periodic inspection of the condition of the concrete allows you to determine the appropriate time frame for each stage of the application.
