of mortar for the setting bed shall not exceed 10mm in thickness.
Apply an additional coat to build up required thickness after
the previous coat is sufficiently cured.
- Cure each
C/S rendering with water sprinkling.

Note :
- Moisturize
and soak the surface of the setting bed with water overnight.
- Apply mortar
on the back of tile onto well prepared wall in about 2-3mm thickness,
and set the tile on the prepared wall surface at once (known as
the "Buttering Method").
- Tap and press
the tile surface well after tile setting to ensure the tile joint
is fully occupied with mortar.
- Cure the
surface for approximately four hours after tile setting and ensure
the tiles are initially set before wiping off the excess mortar
with a sponge and cleaning the surface of the tile with water.
E : Cleaning
Tile Surface
Further mortar
smudge should be removed with 3% solution of industrial hydrochloric
acid after washing surface with water. This shall be done after
the grouting has been cured for seven days.
