SikaLatex®
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.
- 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

|
Application
Ambient air temperature
Min. 5°C – Max. 35°C
Substrate temperature
Min. 5°C – Max. 35°C
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.
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.
