Why Tile adhesive ?

Conventional Story

Cement Paste Shrinks resulting in hollowness behind Tiles.

Why Tile adhesive ?

Cement paste applied at only center of tile and not throughout substrate which will create void space behind tile through which water can seep through
Cement consumption is high
Protection layer: geotextile
Cement paste does not have slip resistance in green stage
Tiles must be soaked in water prior use
Tile on Tile application not possible
