General
General
Pre-laying shall be in accordance with
AS/NZS 2455.1.1996:
In setting up, a point in the room shall be determined
from which the carpet tiles can be installed to
ensure that they are laid
a. Carpet Tiles should be fitted in a stair method
as shown in Fig. 2.
Prior to commencement, the installer should
confirm carpet tiles, type, colour, batch numbers,
tops and bottoms (if applicable) and arrow/
pile direction are all in accordance with the
manufacturer’s specifications and the customer’s
requirements.
––
Parallel to the longest wall, unless specified
otherwise.
––
With not less than one-third of a carpet tile
width at perimeter walls; and on access floors,
with the edge of the modular carpet tile not
corresponding with access floor joints.

Subfloor Condition and Preparation
Where practical there should be full tiles in
doorways and high traffic areas.
Subfloor preparation shall be in accordance with
AS/NZS 2455.1.1996:
The subfloor shall be rigid, clean, dry and be free of
deleterious materials that may have an affect on
the installation. The subfloor shall be tested for
moisture and alkalinity.
Refer to Fig. 1.
NOTE: The porosity and absorption of adhesive
varies with differing subfloor conditions. It is
the responsibility of the installer to ensure the
application rate of product, for each specific
installation is sufficient to achieve the adhesive
manufacturer’s recommended spread rates. Where
there is a cable trunking, the finished surface shall
be level with the subfloor.

they are abutted. To ensure abutment is
correct, measure the carpet tiles after every
10 modules are fitted.
2. Divide in half to find point X which provides the
centre of the room.
Prime the subfloor in accordance with subfloor
preparation in AS/NZS 2455.1.1996 and spread
pressure sensitive adhesive to 100% of the floor
area by trowel, roller, brush or spray in accordance
