i) In the case of
internal wall tiles, the
setting out course or
layout course is
established.
ii) The level and
events of the wall
surface should not
exceed the allowable
tolerance as specified
in the contract. Any
such defect should be
rectified before
proceeding further.
iii) While setting out
for floor tiling, establish
a datum level for the
finished floor and
control the overall level
of the finished floor by
means of series of spot
levels. The Site
Engineer will involve
Consultant’s
representative while
fixing levels.
iv) Avoid cutting tiles
as far as possible. If
cutting cannot be
avoided locate cut tiles
where they will be least

noticeable, if in doubt
refer to specification.
v) The sequence of
fixing tiles shall be as
follows unless specified
otherwise in the
contract:
Floor tiles – from
the centre of room
Internal walls –
Upward from the
setting out course
up to the specified
height (in case of
false ceiling)
otherwise from top
and downwards up
to starting level.
External walls –
always from top to
bottom covering one
horizontal strip after
another but
preferably to be
done in bays.
vi) The mortar or adhesive is
spread on the surface using a trowel
or blade in thin layers as specified.
vii) Before placing the
next tile take care to
allow correct joint width
by placing the correct
spacers in all corner
joints.
viii) Do not start joint
grouting work till tiles
are properly fixed to the
surface. Normally the
time period varies
between 24 hrs to 48
hrs.
