SikaLatex®

Water resistant bonding agent and mortar admixture

SikaLatex® is a synthetic rubber emulsion that is used as admixture for cementitious bonding bridges and high quality site-mix mortars where good adhesion and water resistance are required.

The main advantages of SikaLatex® are:
  • Increased adhesion
  • Reduced shrinkage and cracking
  • Increased abrasion resistance
  • Improved chemical resistance
  • Reduced permeability
  • Improved workability
  • User friendly
  • Suitable on most common construction substrates
  • Non-toxic
  • Non-corrosive
  • Greater flexibility

Consumption

Recommended dosage

For all applications apart from sprayed on renders, a bonding bridge should be brushed into the prepared surface.

       1. Bonding Bridge

Cement : Sand : Liquid (part SikaLatex® + part water) = 1:1:1 (by volume) or

Cement : Sand : Liquid (part SikaLatex® + part water) = 1.5:2:1 (by weight)

Apply the slurry onto pre-wetted substrate in 1-2mm thickness and apply subsequent mortar renders immediately (wet onto wet application).

Consumption: 1 litre of Sikalatex covers 4-6 m² area (depends surface roughness)

Remarks

Screeds with increasing thickness require a lower consumption of SikaLatex®

For thin sections use zone 4 sand. Keep water content at minimum

May be pumped. Use promptly.

Wherever possible saturate surfaces

Note

  • The above mixes are for guidance and based on the use of sharp, well graded aggregates and dry sand. Trials are recommended.
  • For Optimum results, always ensure that the correct SikaLatex® : Water ratio is used as shown in the tables above.
Application steps

MIXING

Mix SikaLatex® with the correct amount of water to produce a gauging solution.

Pour part of the gauging solution into a suitable mixing container. While stirring slowly, add the cement-sand mix to the gauging solution and mix thoroughly until a smooth, uniform and lump-free mix is achieved. Within the mixing time add additional gauging solution to adjust to the desired consistency.

CLEANING OF EQUIPMENT

Remove uncured SikaLatex® from tools and equipment with water. Cured material can only be removed mechanically.
