wet area lining
systems
CeminSeal ™ Wallboard features an embedded micro
waterblock technology that prevents water penetrating into
the sheet, repelling water and providing a more stable sheet.
Ideal for lining areas such as bathrooms, laundries and
semi‑exposed ceilings, and for construction of impact
resistant walls.
The systems in this manual are based on Australian Standard
AS3740 ‘Waterproofing of wet areas within residential
buildings’. The standard details the design, materials,
and installation requirements for wet areas within
residential buildings.
A wet area is defined by the standard as an area within a
building supplied with water from a water supply system,
including bathrooms, showers, laundries and toilets,
but excluding kitchens, bars and similar.
Each wet area is classified as having a high, medium or low
level of risk. Certain walls and junctions in each of the levels
are required to be waterproof or water resistant.
Water resistant walls are those areas enclosing and within
a shower compartment, and walls adjacent to fixed vessels
such as baths, spas and tubs, i.e. part wall areas within
bathrooms, ensuites and laundries.
Waterproof areas are junctions between walls and between
floors and walls in showers and bathrooms, and near baths,
spas, sinks etc.
Cemintel™ Wet Area lining Systems offer proven, reliable and
cost effective solutions to all residential wet areas.
CEMINTEL™ WET AREA LINING & FLOORING SYSTEMS
WATER RESISTANT AREAS

All Cemintel™ sheeting must be stacked flat, off the ground,
and supported on a level platform. Care must be taken to
avoid damage to edges, ends and surfaces. Material must
be kept dry, preferably by being stored inside the building.
Where it is necessary to store sheets outside, they must be
protected from the weather.

When cutting or grinding fibre cement sheets using power
tools, always ensure the work area is well ventilated. An
approved dust mask (AS1715 and AS1716) and safety
glasses (AS1337) must be worn. CSR recommends that
hearing protection be worn where appropriate.
CEMINTEL™ WET AREA LINING & FLOORING SYSTEMS
sheet preparation
CUTTING
Cemintel™ Sheets may be cut on-site using any of the
following methods.
Tungsten Tipped Score and Snap Knife
1. Score face of sheet 4 to 5 times using a tungsten tipped
knife against a straight edge.
5
Power Saw
When it is necessary to use power tools for cutting Cemintel™
Sheets, CSR recommends using the Hitachi Fibre Cement
Power Saw Blade. This blade is specifically designed for use
with fibre cement and produces a superior cut compared to
conventional blades.
It is ideal for use with the Hitachi C7YA dustless circular
saw and other 185mm circular saws fitted with vacuum
extraction systems.
2. Support the scored edge with the straight edge and snap
the sheet upwards for a clean break.

ON-SITE RECESSING
Hand Saw
Preferably use an old handsaw. A quick jabbing action is
best. Work with sheet face up to prevent burrs forming on
the face.
Where it is necessary to produce a ground recesson
on-site, a dustless angle grinder should be used. CSR
recommends using the Hitachi Easy Bevel with vacuum
extraction system, which fits most 125mm grinders,
and produces a superior finish.
The recess should be 1.5mm to 2mm deep, and should be
approximately 35mm wide.

CEMINTEL™ WET AREA LINING & FLOORING SYSTEMS
control joints
Control joints are to be installed in large spans of wall to allow
for structural movement, and are to be positioned:
1. In non-tiled areas at not more than 7.2m spacings.
2. In tiled areas at not more than 4.2m spacings and at
internal corners.
3. To coincide with control joints in the supporting frame.
4. At changes of framing type.
Control joints are to be constructed with a double stud, and
allowance for expansion/contraction is to be made in both
the wallboard and tiles.
The following methods are recommended.

When an external shower tray or perimeter angle flashing
is used, it is not permitted to fix the wallboard sheet to the
bottom plate. An additional row of noggings must be placed
25mm above the tray or flashing to allow the wallboard to
be fastened.
Similarly, noggings are to be placed 25mm above a preformed
shower base, sink or bath tub. Also provide suitable noggings
to support the bath and other fixtures such as soap holders
and towel rails.
Wall framing may be checked-out to a maximum depth of
20mm to accommodate the bath or shower base flange.
Alternatively, provide furring to ensure the face of the
CeminSeal™ Wallboard will finish in front of the upturn on
the receptacle.
For masonry substrates, wallboard must be fixed to furring
channels in both tiled and non-tiled areas.
CEMINSEAL™
wallboard
installation
Generally, it is recommended that all CeminSeal™ Wallboard
sheets be applied horizontally. This is to reduce the extent of
joint visibility in glancing light conditions. Sheets may be fixed
vertically in tiled areas or where joint visibility is not an issue.

Steel framing must comply with AS3623 : 1993 ‘Domestic
Metal Framing’.
Butt joints must be staggered a minimum of 600mm in
adjacent sheets.
Avoid butt joints over doorways and windows. Where these
are unavoidable, they are to be positioned a minimum 200mm
from jamb studs, and formed on a stud.
Install the bottom sheet first, with the lower edge a minimum
6mm clear of the finished floor.
Fasteners are to be positioned a minimum of 12mm from the
edge of the sheet and a minimum 50mm from sheet corners.
Fasteners are to be left a maximum of 0.5mm below the
sheet surface.

shower recess construction
PREFORMED SHOWER BASE
A preformed shower base has the advantage of being easy to
install over floors of timber, compressed fibre cement sheet
and concrete slabs, as well as ensuring that the wall linings
are kept clear of any free water likely to accumulate on the
shower floor.
A preformed shower base must be installed before the wall linings.
Note: Australian Standard AS3740 states that – The height of the
sides of a shower tray above the highest point of the finished floor
surface shall be the greater of –
i) 75mm; or
ii)25mm above the maximum possible water level in the shower
FIGcompartment.

Note:
1. Water Resistant Areas are defined in AS3740 ‘Waterproofing of wet areas within buildings’. It is recommended that a water resistant taping
compound, such as CSR Gyprock™ Wet Area Base Coat be used in these areas.
2. When using Basecoat 45 in hot or extreme drying conditions, mix only small quantities of compound. Leave the compound standing for
approximately 15 minutes to ensure that it sets soon after application to the joints. Additionally, depending on the severity of the drying
conditions, the surface of the area may be wetted with a brush before applying the compound. Do not use Base Coat when temperature
is below 10°C.

CEMINTEL™ WET AREA LINING & FLOORING SYSTEMS
JOINTING COMPOUNDS
GYPROCK jointing compounds are classified as either setting
type, drying type or acrylic drying type. All compounds can
be applied by hand or with mechanical jointing tools.
Setting type compounds produce stronger joints and reduce
installation delays and shrinkage associated with drying-type
compounds. They are recommended for experienced trades
people and have a defined setting time e.g. 45 minutes.
Setting type compounds are: BASE COAT 45.
Additional coats may be applied over setting type compounds
once they have gone hard (set), usually 40 minutes to an
hour. A drying type compound must be used as a finish coat
and must be completely dry before sanding. This may take
up to 24 hours.
Drying type compounds are:
Acrylic drying type compounds are:
WET AREA BASE COAT. This compound, when used in
conjunction with Paper Tape or Easytape™, produces very
strong and durable joints. These joints are resistant to some
movement without displaying weak joints.
Dr ying type compounds will shrink and harden with
evaporation of their water content. The joints must be
allowed to set and appear completely dry before re-coating
or sanding. Actual drying times will be extended in low
temperature and high humidity conditions. Do not use a
setting type compound over a drying type compound.
JOINTING TAPE
Gyprock™ Paper Tape has been developed to enable the
preparation of strong joints and should be used on butt and
recess joints as detailed in Table1 1.
Gyprock Easytape™ is ideal for use with Wet Area Base
Coat, provided it is bedded into the compound. Sticking
Easytape™ to the fibre cement sheet is not recommended,
and could result in weak joints.

WALLPAPERING
For best results, the surface of CeminSeal™ Wallboard should
be sealed with a pigmented oil base sealer before applying
wallpaper or other decorative materials.
TILING
Tiles shall be installed in accordance with AS3958.1.
Allowance must be made for expansion/contraction by
leaving a gap between adjoining tiles in vertical corners. Fill
gap with flexible wet area sealant.
Refer to section on Control Joints for additional requirements.
The tiler must ensure that all loose dust and foreign matter
are cleaned off the surfaces to be tiled.
Proprietary tile adhesives that meet AS2358 : 1990 ‘Adhesives
for ceramic wall tiles and mosaics’ are recommended.
Tiling is to be in accordance with the tile adhesive
manufacturer’s instructions. Priming of joints and/or board
may be required. A compatible tile adhesive must be used
to fix tiles to proprietary membranes.
Spread adhesive onto the surface to a depth of about 3mm,
then ‘rib’ in a horizontal direction with a notched trowel having
approximately 4.5mm x 4.5mm notches.
CORNICE
Details for fixing cornice are given in GYP547, Gyprock
Residential Installation Guide. When fixing cornice to

installation
Cemintel™ Compressed Sheet may be fixed over timber or
steel joist systems.
FIXING COMPRESSED SHEETS
Timber framing must comply with AS1684 : 1992 ‘National
Timber Framing Code’.
21
Sheets may be fixed in place prior to or after wall framing
is installed.
Steel framing must comply with AS3623 : 1993 ‘Domestic
Metal Framing’.
All compressed sheet ends must be supported by a framing
member. Wherever possible plan sheet layout to avoid the
need to cut sheets.
For upper storey construction, the use of durable seasoned
timber or composite joists is recommended to minimise
differential movement resulting from joist shrinkage.
Sheets must be screw fixed at 450mm maximum centres
along sheet edges and in the body of the sheet.
Joists must have a minimum face width of 38mm and should
be spaced as follows:
15mm sheet – 450mm maximum centres.
18mm sheet – 600mm maximum centres.
Wherever possible joist and sheet layout should be planned
to ensure the long edges of compressed sheets are installed
across the floor joists, and to ensure the end of the sheet is
fixed on the centre line of the joist.
Sheets that are fixed parallel to the floor joists must have both
long edges continuously supported along the centre line of
joists. Sheet ends must also be fully supported by framing.
sheet
preparation
When cutting or grinding fibre cement sheets using power
tools, always ensure the work area is well ventilated. An
approved dust mask (AS1715 and AS1716) and safety
glasses (AS1337) must be worn. CSR recommends that
hearing protection be worn where appropriate.
Screws must be kept a minimum of 12mm from the edge of
sheets and 50mm from corners.
Screw holes must be pre-drilled using a masonry bit, allowing
1mm clearance over the diameter of screw.
All sheet joints must be sealed using MegaPoxy P1, a two
part water based epoxy adhesive, that must be mixed just
prior to use. It is important to ensure sheet edges are clean
and free of any dust.
Adhesive must be applied to the edge of the first sheet once
it is fixed in position. Butter adhesive along sheet
Ensure sheets are pushed together tightly for adequate
adhesion, and the joint is filled.

PLUMBING WASTES
It is important that all plumbing wastes are sealed, particularly
in a shower recess.
A PVC waste yoke must be bonded to the flooring and the
waste pipe using HydrEpoxy™ 501 before fitting grates and
other fixtures.
A waste fitting incorporating a ‘leak control system’ is
recommended to enable any moisture to drain from beneath
the floor tiles.

If a fall to waste is not required, tiles may be fixed directly to
Cemintel™ Compressed Sheet.
Tile adhesive must conform to Australian Standard AS2358
‘Adhesives - for fixing ceramic tiles’.
If a fall to waste is required, tiles must be bedded into a
mortar bed which is not less than 12mm thick.
In all cases the tile and tile adhesive manufacturers’
instructions should be followed.
