Technical Information

Mortar mix design

SikaLatex® 4LK is generally added to the clean mixing water within the range of 1:1 – 1:2.5 for all applications, apart from sprayed-on renders, where a bonding slurry should be applied.Subsequent mortar application must be carried out while the bonding coat is still wet. Aggregates should be well graded and thoroughly washed. Sand particle sizes should correspond to the thickness of mortar to be applied and requiredsurface finish.

Mortar Thickness                                              Aggregate Size

< 2 mm                                                               0–0.5 mm
2–5 mm                                                              0–1.0 mm
