1 Introduction
Hardie™Groove Lining combines the appearance of traditional timber tongue and groove wall panelling with the
benefits of modern fibre cement.
Because the baseboard is Hardie™fibre cement, it’s resistant to fire, rot resistant and resistant to moisture damage
when installed and maintained as directed.
Hardie™Groove Lining has decorative v-shaped grooves carved into the front face of the 7.5mm sheet, and is
sanded, ready to be painted in any colour.
Hardie™ Groove Lining can be fixed to the full height of the wall or at dado height to create a decorative, hard-
wearing, impact resistant lining in hallways and to withstand the toughest treatment in family rooms, rumpus
rooms, laundries and bathrooms (not suitable for shower areas).
Hardie™Groove Lining is also ideal for use in ceilings, either to add interest to a modern design, or to create
historical detail on a renovation project.
The main features of Hardie™Groove Lining are:
• Durable internal lining, sot and ceiling sheet.
• Creates suitable surface for paint finish.
• Sheet edges have a ‘half groove’ to achieve concealed sheet joints.
• Reliable impact resistant decorative lining. Ideal for wall lining where walls are prone to damage.
• Resistance to damage from moisture making it ideal for bathrooms, laundries and kitchens.
• Joints won’t pull or shift apart.
• Authentic v-shaped grooves replicate traditional tongue and groove look and style.
• Ideal as feature wall to dado height.
The specifier or other responsible party for the project must ensure the information and details in this guide are
appropriate for the intended application and specific design and detailing is undertaken for areas which fall
outside the scope of this documentation.

2 Safe Working Practices
WARNING - DO NOT BREATHE DUST AND CUT ONLY IN WELL VENTILATED AREA
Hardie™fibre cement products contain sand, a source of respirable crystalline silica. May cause cancer if
dust from product is inhaled. Causes damage to lungs and respiratory system through prolonged or repeated
inhalation of dust from product.
Intact fibre cement products are not expected to result in any adverse toxic eects. The hazard associated with
fibre cement arises from the respirable crystalline silica present in dust generated by activities such as cutting,
rebating, drilling, routing, sawing, crushing, or otherwise abrading fibre cement, and when cleaning up, disposing
of or moving dust.
When doing any of these activities in a manner that generates dust, follow James Hardie’s instructions and best
practices to reduce or limit the release of dust.
If using a dust mask or respirator, use an AS/NZS 1716 P1 filter and refer to Australian/New Zealand Standard
1715:2009 Selection, Use and Maintenance of Respiratory Protective Equipment for more extensive guidance and
more options for selecting respirators for workplaces. For further information, refer to our installation instructions
and Safety Data Sheets available at www.jameshardie.co.nz.
FAILURE TO ADHERE TO OUR WARNINGS, SAFETY DATA SHEETS, AND INSTALLATION INSTRUCTIONS MAY LEAD
TO SERIOUS PERSONAL INJURY OR DEATH.
Crystalline Silica is
• Commonly known as sand or quartz
• Found in many building products e.g. concrete, bricks, grout, wallboard, ceramic tiles, and all fibre cement
materials
Why is Crystalline Silica a health hazard?
• Silica can be breathed deep into the lungs when present in the air as a very fine (respirable) dust
• Exposure to silica dust without taking the appropriate safety measures to minimise the amount being breathed
in, can lead to a potentially fatal lung disease – silicosis – and has also been linked with other diseases including
cancer. Some studies suggest that smoking may increase these risks
• The most hazardous dust is the dust you cannot see!
When is Crystalline Silica a health hazard?
• It’s dangerous to health if safety protocols to control dust are not followed when cutting, drilling or rebating a
product containing crystalline silica
• Products containing silica are harmless if intact (e.g. an un-cut sheet of wall board)
Hardie™ Groove Lining Installation Manual | July 2021 New Zealand 7

Avoid breathing in crystalline silica dust
Safe working practices
NEVER use a power saw indoors or in a poorly ventilated area
NEVER dry sweep
ALWAYS use M Class or higher vacuum or damp down dust before sweeping up
NEVER use grinders
ALWAYS use a dust reducing circular saw equipped with a sawblade specifically designed to minimise dust
creation when cutting fibre cement – preferably a sawblade that carries the Hardie™Blade name or one with
at least equivalent performance – connected to an M Class or higher vacuum
Before cutting warn others in the area to avoid dust
ALWAYS follow tool manufacturers’ safety recommendations
ALWAYS expose only the minimum required depth of blade for the thickness of fibre cement to be cut
ALWAYS wear a properly-fitted, approved dust mask or respirator P1 or higher in accordance with applicable
government regulations and manufacturer instructions
Consider rotating personnel across cutting tasks to further limit respirable silica exposures.
Use one of the following for cutting:
Best
• Hardie™Knife
• Hand guillotine
• Fibreshear
Better
Dust reducing circular saw equipped with Hardie™Blade Saw Blade and connected to a M Class or higher
vacuum.
When cutting outdoors
Make sure you work in a well ventilated area
Position cutting station so wind will blow dust away from yourself and others in the working area
Cut products with either a Hardie™ Knife or fibre cement shears or, when not feasible, a Hardie™ Blade Saw
Blade (or equivalent) and a dust reducing circular saw connected to a M Class or higher vacuum
When sawing, sanding, rebating, drilling or machining fibre cement products, always:
- Wear your P1 or higher mask (correctly fitted in accordance with manufacturers’ instructions), ask others to
do the same.
- Keep persons on site at least 2 metres and as far as practicable away from the cutting station while the saw
is in operation
- If you are not clean shaven, then use a powered air respirator with a loose-fitting head top
- Wear safety glasses
- Wear hearing protection
- When others are close by, ask them to do the same
Make sure you clean up BUT never dry sweep. Always hose down with water/wet wipe or use an M Class or
higher vacuum
8 Hardie™ Groove Lining Installation Manual | July 2021 New Zealand

When cutting indoors
Never cut using a circular saw indoors
Position cutting station in a well ventilated area
Cut ONLY using a Hardie™Knife, hand guillotine or fibreshears
(manual, electric or pneumatic)
Make sure you clean up BUT never dry sweep. Always hose
down with water/wet wipe or use an M Class or higher
vacuum
Working instructions
Hardie™Blade Saw Blade
The Hardie™Blade Saw Blade used with a dust-reducing saw is
ideal for fast, clean cutting of Hardie™fibre cement products. A
dust-reducing saw uses a dust collector connected to a M Class or
higher vacuum. When sawing, clamp a straight edge to the sheet
as a guide and run the saw base plate along the straight edge
when making the cut.
Hole forming
For smooth clean cut circular holes:
• Mark the centre of the hole on the sheet
• Pre-drill a ‘pilot’ hole
• Using the pilot hole as a guide, cut the hole to the appropriate diameter with a hole saw fitted to a heavy duty
electric drill
For irregular holes:
• Small rectangular or circular holes can be cut by drilling a series of small holes around the perimeter of the hole
then tapping out the waste piece from the sheet face
• Tap carefully to avoid damage to sheets, ensuring that the sheet edges are properly supported
2.1 Storage and delivery
Keeping products and people safe
O loading
Hardie™fibre cement products should be o-loaded carefully by hand or by forklift
Hardie™fibre cement products should not be rolled or dumped o a truck during the delivery to the jobsite
Storage
Hardie™fibre cement products should be stored:
In their original packaging
Hardie™ Groove Lining Installation Manual | July 2021 New Zealand 9

Under cover where possible or otherwise protected with a waterproof covering to keep products dry
O the ground – either on a pallet or adequately supported on timber or other spacers
Flat so as to minimise bending
Hardie™fibre cement products must not be stored:
Directly on the ground
In the open air exposed to the elements
James Hardie is not responsible for damage due to improper storage and handling.
2.2 Tips for Safe and Easy Handling of Hardie™Groove Lining
Carry with two people
Hold near each end and on edge
Exercise care when handling sheet products to avoid damaging the edges/corners
3 Framing
3.1 General
Hardie™Groove Lining can be fixed to either timber or light gauge domestic type steel framing. The framing used
must comply with the relevant building regulations and standards and the requirements of this manual.
Note: Hardie™Groove Lining must not be used in shower areas.
3.2 Timber
Timber framing must comply with the durability requirements of Clause ‘B2’ of the NZBC. Timber must be treated
as per the requirements of the NZS 3602.
Timber framing sizes and set out must satisfy the minimum requirements of NZS 3604 and this installation guide.
The minimum stud width of 35mm may be used. However, where butt jointing is used the minimum stud width is
45mm at the joint. See Figure 13.
Reference NZS 3604 ‘Timber-framed Buildings’.
10 Hardie™ Groove Lining Installation Manual | July 2021 New Zealand

3.3 Steel
The minimum size for steel stud framing should be 64mm deep x 0.55mm base metal thickness (BMT). Steel
framing shall comply with NASH 3405 Steel Framed Buildings. Steel sections shall be galvanised or zinc coated of
0.55mm — 1.6mm BMT. Studs must not be less than 38mm wide at butt joints.
Figure 1: Frame straightness
3.4 Preparation
Ensure frame is square and work from a central datum line. Frames must be straight and true to provide a flush
face to receive the sheeting.
A suggested maximum tolerance of between 3mm and 4mm in any 3000mm length of frame will give best
results. Hardie™Groove Lining will not straighten excessively warped or distorted frames and any warping may
still be visible after the internal lining is installed.
Hardie™ Groove Lining Installation Manual | July 2021 New Zealand 11

4 Installation
4.1 Sheet Layout
Hardie™Groove Lining is usually fixed vertically. Sheet joints must coincide with the centre line of the framing
member.
The long edges of the sheet have a unique half groove, which achieves a concealed joint.
Where fixing half height sheets as a dado wall, provide a row of noggings to allow for fastening of the sheet edge.
When fixing around window openings, best practice would be to align the sheet joints with the window jamb.
4.2 Fasteners
Fasteners must have the appropriate level of durability required for the intended project.
Fasteners must be fully compatible with all other material that they are in contact with to ensure the durability and
integrity of the assembly.
• On timber frame use Villadrive™screws 30mm x 6g or Hardie™Drive stainless steel screws for quick installation
of Hardie™Groove Lining.
• Alternatively the Hardie™Groove Lining can be fixed with 40 x 2.8mm Hardie™Flex nails or ND 50 brad nails.
• For fixing Hardie™Groove Lining to 0.55 – 1.0mm BMT steel framing, use 30mm Buildex®FibreTEKS collated
screws.
Nails must be finished flush (Figure 2). Screws can be driven 0.5mm below the sheet surface to achieve the
required finish level (Figure 2). In steel framing the fasteners should be driven as close as possible to the stud
corners to avoid deflection of the stud flange, see Figure 3.
