The HardiePlank Installation Manual runs through the installation process from storage and handling through to the physical installation of the battens, strips, HardiePlank boards and trims.
HardiePlank Installation: Fibre cement boards
HardiePlank® Cladding is an 8mm thick plank and is designed for external cladding. It looks equally at home in residential and commercial buildings, either new builds or renovation. While these cement-fibre boards are durable they do require correct manual and mechanical handling. Care should also be given to storage and installation to maximize the benefits of this quality product.
Handling with care
The HardiePlank boards are 8mm x 180mm wide and they are 3.6 metres long. Fibre cement is remarkably dense and they weigh approximately 7.4 kg per board. Consequently they are best handled by two persons wherever possible, but most importantly they should be carried on edge.
Storage of the cladding
HardiePlank® cladding and fibre cement trims are made of Portland cement, milled sand, cellulose fibres, water and selected additives. It is vital therefore that these products are stored flat and kept dry prior to installation. If the products have to be stored outside they should be covered with a waterproof covering in addition to the product wrapper to avoid contact with water and dust. Wet products must not be installed, it will result in shrinkage at butt joints. Neither James Hardie or Southern Timber can be held responsible for damage caused by improper storage and handling of the product.
James Hardie do not specify the fastening requirements for the framing to the building. The batten framing should be incorporated into the overall building design and should be approved by the responsible parties. Waterproof membrane and the installation of the EPDM tape, or gasket, should be considered an integral part of the design. Safety precautions must be considered, cutting and drilling will generate dust and must be done outdoors only.
HardieBlades or Guillotine for cutting
For cutting cement fibre boards use a diamond tipped HardieBlade® saw blade for a neat finish. Similar results can be achieved with the Hardie Guillotine™ manual cutting tool, both tools keep the dust levels lower than a conventional power saw. All cut ends must be sealed with Touch-up paint immediately with a small artist brush. Boards can be installed horizontally or vertically. The HardiePlank Cladding can be nailed by hand or with a gun but the nails must be flush installed. 38mm stainless nails can be used for hand fixing then the nail top can be painted over.
ColorPlus Touch Up paint
Hopefully careful handling and storage will keep your fibre cement cladding in pristine condition ready for installation. If there is any cosmetic damage then the JamesHardie ColorPlus® touch up paint should be used to deal with small scratches and marks less than 6mm. All cladding and trims must be sealed with Touch-up paint prior to installation with a small artist brush. Any excess paint must be wiped carefully from the front profile face immediately.
