Tips & Tricks for:
The James Hardie gecko gauge allows precise one-person siding installation with less time, frustration, and fatigue. It increases installation time up to 50%. Next to that each plank covers 0.54 sq. m of lapped elevation, no waste.
Hardie plank offers color plus, so that you don’t have to paint it again.
When estimating material, we recommend adding an additional 10% for waste.
James Hardie® Cladding
HardiePlank cladding is a versatile weatherboard that offers the texture and natural beauty of timber whilst delivering the maintenance-free durability of fibre cement.
Available in an extensive range of colours, plus a choice of two textures, HardiePlank can also be installed horizontally, vertically or diagonally, providing the flexibility to create any design. HardiePlank works equally well as a ‘full wrap’ cladding solution or as an accent that complements traditional building materials such as stone, wood and brick.
With ColorPlus® Technology, the long lasting durability provided by HardiePlank offers major advantages over conventional cladding materials, providing ease of installation, design flexibility and enhanced durability.
Made from an advanced material that’s five times thicker than typical vinyl cladding, HardiePlank is fire, moisture, rot and pest resistant. It’s unaffected by rain and hail damage and can be installed to withstand winds of up to 150 mph.
From classic to contemporary, there is a HardiePlank product that will help you achieve the perfect look and finish for your project.

- How do I cut HardiePlank cladding? How can I control the dust?
We sell a range of specialist tools designed to cut our products quickly, effectively and with a minimum of dust. The best are hand tools like the HardieGuillotine™ which is available from your distributor. Always use approved safety glasses and appropriate EN approved respiratory protection (PPE #2 or #3) for particulate hazards when working with HardiePlank cladding and HardieTrim® NT3™.
- Do I have to treat the cut ends of the planks in any way?
Yes. All cut ends on HardiePlank® cladding should be painted with our ColorPlus® touch-up paint. This prevents unwanted water ingress into the cut edge.
- How much HardiePlank cladding will I need and how can I do a rough estimate?
There are approximately two planks to the square metre. Measure the width and height, in metres, of each wall to be clad. Multiply the two dimensions together to give you the area in square metres of each wall and then multiply this total by two to give you the total number of planks for each wall. Add all your walls up and this will be a reasonable guide to how many planks you need to order.
- Do I need to pre-drill HardiePlank cladding before fixing?
No. There is no need to pre-drill HardiePlank® cladding for either nail or screw applications.
- What nailing techniques can be used to install HardiePlank cladding?
You can use impulse or pneumatic nail guns as well as nailing by hand. Nails should be placed 20-25mm down from the top edge of each plank and driven into the batten with the heads flush with the surface of the plank.
- How much do I need to overlap HardiePlank cladding?
Planks should be overlapped 30mm leaving a visible margin of 150mm.
- Do I have to butt the joints? Will water get through the gap? Do I have to seal with mastic?
Planks should be butt jointed over a batten. Do not joint planks between battens as this could lead to failure of the product. Some rainwater may penetrate the butt joint, and whilst this is not a problem in itself as the system operates as an unsealed rain screen, it is good building practice to provide protection to the batten reducing the risk of the batten rotting over time. This can be easily achieved by fixing a small piece of EPDM tape on the batten at the point where the boards will but each other (see installation guide for details). Alternatively a small bead of transparent general mastic placed at the line of the joint will perform a similar function. Any excess should be wiped off the face of the plank immediately
- How close to the ground can I install HardiePlank cladding?
A clearance of 150 mm should be maintained between the bottom edge of the lowest layer of HardiePlank cladding and any unpaved ground. This will allow for clearance when soil is back-filled against the foundations and footings and prevent the bottom plank being damaged by contact with soil and rainwater splashing up the wall.
- What types of trim can be used with HardiePlank cladding?
HardieTrim® NT3™ is the preferred trim material for use with HardiePlank cladding. HardieTrim® NT3™ has the durability and paint holding characteristics to match the proven performance of HardiePlank cladding. Other trim materials may be used; however some of these may need a more intensive maintenance program.
- Do you require a weather-resistant barrier behind HardiePlank cladding?
Yes. The use of a weather resistant barrier reduces the potential for the entry of moisture into the exterior wall of the building. It is good building practice.
- What type of weather-resistant barrier is required?
Any weather-resistant membrane complying with BS-EN1521 and having a vapour resistance of 0.6 MNs/g is acceptable.
- Can HardiePlank cladding be applied to metal framing?
Yes. Apply a sheathing layer of OSB or marine plywood followed by, a weather resistant membrane and timber battens over the face of the metal frame, and install the HardiePlank® cladding as per the installation instructions. The site engineer should ensure that the fixing specification of the sheathing and battens to the steel studs sections satisfies the engineering demands placed on the structure.
- There appears to be a plastic film on the front face of HardiePlank cladding, when should I remove this?
The plastic film helps protect the finish from damage during transportation, storage and installation. We would suggest that it is removed last thing from the top edge down as the fixings are inserted.
- What’s the maximum horizontal fixing support centre?
600mm, but this should be checked by a qualified engineer as this is linked with your local wind loads.
All James Hardie® fibre cement products are covered by a 10-year limited warranty.
