Application
Recommended dosage
1. Bonding Bridge
Cement : Quartz Sand : Liquid (1 part SikaLatex® + 1 part Water) = 1 : 1 : 1 (by volume)
or,
Cement : Quartz Sand : Liquid (1 part SikaLatex® + 1 part Water) = 1.5 : 2 : 1 (by weight)
Apply the slurry by brush onto the pre-wetted substrate in 1-2 mm thickness and apply the subsequent mortar renders immediately (wet on wet application).

Remarks
For thin sections use Sikadur aggregate size dependent on layer thickness. Keep water content at a minimum.
The above mixes are for guidance only and based on the use of sharp, well graded aggregates and dry sand. Trial mixes must be performed to establish the exact dosage rate required. For optimum results, always ensure that the correct SikaLatex® : Water ratio is used. Depending on the application and performance required, Sika Latex® may be added to the clean mixing water within the range of 1:1 to 1:4. For all applications apart from sprayed on renders, a bonding bridge should be brushed into the prepared surface.
Layer Thickness Aggregate Grading Sika Aggregate

Aggregates should be sharp, well and thoroughly washed. Sand particle sizes should correspond to the thickness of the applied mortar and to required surface finish.
MIXING
Mix SikaLatex®-IQ 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
Clean all tools & application equipment with water immediately after use .
Hardened / Cured material can only be mechanically removed .
