Min. 10 mm
Max. 40 mm
Ambient air temperature
+5 °C min. / +40 °C max.
Substrate temperature
+5 °C min. / +40 °C max.
Fresh mortar density
~2.21 kg/l (+25 °C)
Yield

MIXING
Mix the full bag of SikaEmaco® S 422 with the necessary amount of cold water in a clean bucket. Add the SikaEmaco® S 422 powder slowly to the water while mixing continuously for at least 3 to 5 minutes and until a homogeneous consistency is achieved.
SikaEmaco® S 422 is best mixed in a forced action mixer. Slow speed double paddle drill can be also used for mixing. Do not mix at faster rate than 500 rpm. The obtained mix results should be very creamy, easily spreadable and thixotropic.
APPLICATION
Apply SikaEmaco® S 422 while the bonding agent is still wet. The mortar can be applied by spatula or trowel.
For any thickness more than 40 mm, SikaEmaco® S 422 must be applied in several layers. As soon as the mortar has started to set it can be smoothed by wooden or synthetic float. For fine surface finish SikaEmaco® N 907 or SikaRep® Fine N can be applied over the SikaEmaco® S 422.
CURING TREATMENT
Where ambient conditions may lead to rapid surface drying, the use of light water fogging, damp hessian and polythene sheet or application of a suitable water based curing compound like Sika® Antisol range is recommended. Do not commence fogging until final set has been reached.
CLEANING OF EQUIPMENT
Clean all tools and equipment with water immediately after use. Hardened SikaEmaco® S 422 can only be removed mechanically.
