Unicrete Smart Bond

Pre-mixed, self-curing & non-shrink block jointing mortar

Unicrete™ Smart Bond (AAC block joining mortar) is a pre- mixed, self-curing cementitious mortar for laying of
AAC, CLC, Hollow concrete blocks and bricks. It’s a factory-made premixed mortar blended with carefully
selected raw materials such as graded sand, mineral binders and ordinary portland cement (OPC) in combination
with selected polymer and chemical additives which help in providing excellent mechanical bond and adhesion
between the blocks and block to surface.

Designed for use with water to produce high strength thixotropic mortar, with remarkable water retention
properties, even when applied in thin layers of 3 – 4 mm.
