Sika® CemCrete

Multifunctional acrylic based polymer for waterproofing applications

Sika® CemCrete is a multifunctional acrylic polymer emulsion for enhancing the properties of cement slurry or mortar. It provides a good adhesion, water resistance and improvement of several other properties.

  • Easy to apply by brush, slurry consistency
  • Durable and effective waterproofing treatment for most areas
  • Good bonding with most of the substrates.
  • Improves resistance to salt permeation
  • Improves impermeability
  • Non-corrosive to steel & iron
  • Vapour permeable
  • Can be used as a bonding agent for mortar and plasters during repairs in combination with cement

NOTE:

The above stated consumption depends on substrate conditions, porosity level, application skills,etc. The ratios and consumptions mentioned above if for guideline only and may have to be slightly altered at site based on the type of cement used (OPC/PPC/Other blended cements) .It is advised to conduct a site trial to arrive at the correct consistency required for the particular type of application mentioned above .Small quantity of water may be added in case mix is not workable at very high temperatures.

MIXING

  1. Pour required quantity of product into a suitable mixing container.
  2. While stirring slowly, add the cement or cement-sand mix to the product and mix thoroughly until a smooth, uniform and lump-free mix is achieved.
  3. Within the mixing time add additional product to adjust to the desired consistency. Mix with a mechanical paddle mixer at 300-500 rpm for not more than 2-3 minutes.
 

CLEANING OF TOOLS

Clean all tools and application equipment with clean water immediately after use. Hardened or cured material can only be removed mechanically
