SikaCem® Concentrate

General purpose bonding agent

SikaCem® Concentrate is a general purpose bonding agent for bonding cement plasters and screeds to concrete, masonry and brick substrates.

  • Provides excellent adhesion of the plaster or mortar to most mineral based substrates.
  • Can be used for new work or repair work.
  • Increases strength and durability.
  • Increases surface hardness and significantly reduces the problem of surface dusting.
  • Will enable a tighter, denser and more uniform surface finish to be achieved on mortars, toppings and renderings.
  • Improves bond of subsequent coatings.
  • Easy to use.
  • Economical.

Consumption

Consumption

As a bonding agent:

  • 1 litre of SikaCem® Concentrate is diluted to make 2 litres of bonding agent.
  • 1 litre of diluted product will cover an area of approximately 3 – 6m2 (depending on surface roughness and porosity).
  • Therefore, 1 litre of SikaCem® Concentrate will cover an area of 6 – 12m2.
Application steps

MIXING

Typical Mixing Ratios (by volume), SikaCem® Concentrate: Water:

  • As a bonding agent for screeds, toppings and rendering: 1 : 1
  • As an additive to reduce surface dusting: 1 : 6

Mix together a measured amount of SikaCem® Concentrate and water to suit the required application (refer to ‘Technical Data’ above).  Stir until well dispersed. When used as an additive to reduce surface dusting:

  • Consideration should always be given, when diluting SikaCem® Concentrate, to the amount of water already present in the sand.
  • Slowly add the diluted SikaCem® Concentrate to the preblended dry sand/cement while mixing continuously.  Mix until a uniform and lump free consistency has been achieved.

CLEANING OF TOOLS

Clean all tools and equipment with water immediately after use. Hardened mortars containing SikaCem® Concentrate can only be removed mechanically.
