Fixing Planks

Begin fixing first plank at an external corner. Rest the plank on the datum line nails, and fasten the bottom edge to each stud through the starter strip. Ensure the plank is flush with the corner.

Continue to fix the first row of planks around perimeter of building using either a concealed joint strip or PVC joiner to join each plank. Once the first row is complete remove the guide nails.

Begin the second row with an offcut to ensure that the joints are staggered along the wall. A minimum lap of 25mm is recommended for Fibre Cement Cladding Plank. Use a storey or lap gauge to position successive rows and maintain uniformity. Check rows for level.

Nail planks to timber frames with Fibre Cement Nails 2.8mm x 40mm. Fix through two plank thicknesses, approximately 12mm from bottom of plank. Fasteners must be a minimum of 20mm from plank end.

Planks may also be fixed to timber frames using stud clips. Refer to steel stud section for fixing detail.

Fixing to Steel Studs

When fixing to steel frames, the use of stud clips is recommended. Once the first row of planks is in place, stud clips are positioned along the top edge of the plank. Successive rows of planks are then supported by the bottom lugs of the clip, and fastened to each stud along the top edge of the plank. It is recommended that every few rows are checked for alignment. Planks may also be fixed directly to steel frames. Screws should be positioned approximately 35mm from bottom of plank, through single thickness only.


Fibre Cement Cladding Plank may be jointed using either concealed joints or a PVC plank joiner. Stagger joints randomly throughout the wall. Joints should be formed midway between studs.

Plan plank layout so that where possible a full plank width remains under or over window and door openings: If a plank has been reduced in width, provide a joint at one end of the opening. When a window or door opening exceeds 1800mm width, it is necessary to have a joint above and below the opening to allow for movement.

When steel framing is used, it is essential all openings have a join above and below, regardless of opening width.

PVC Plank Joiner

PVC Plank Joiners are installed in each vertical joint progressively as planks are installed. Joiners lap downward over the lower row. Cut joiners as required to fit at heads,sills and eaves.

Concealed Joint

Where a concealed joint is preferred, an express joint is formed using a concealed joint strip. This joint is filled with sealant and painted over. It is essential that plank ends are square, and rasped before jointing to ensure a neat finish.

The concealed joint strip is fitted onto the plank end, hard up against the tabs, and placed on top of the lower row of planks. The plank is then nailed to the studs.

Butt edge of next plank up to joiner tabs, and nail into place.

Fill 3mm gap with sealant, ensuring any excess is removed. Sealant is covered when plank is painted.

Corner Detail.

Corners can be finished by butting planks up to a timber moulding, or by fixing preformed metal corners.

All internal and external corners are to be weatherproofed with an approved flashing.

Timber Mouldings

Timber mouldings must be installed prior to the fixing of planks.

Plank ends must be straight and square, and are to be butted up firmly to timber stop.

Fasteners should be 20mm minimum from corner. Where fasteners are closer than 50mm from a corner, the hole must be pre-drilled.

Preformed Metel Corners

Splay cut adjoining plank ends and butt together at corner. Fit the preformed metal corners by locating the bottom flange under the planks. Push upwards until the corner is flush with the lower plank edge. Fasten with one nail through the hole at the top.


Fibre Cement Cladding Planks should be finished with 2 coats of exterior grade acrylic paint. The surface must be clean and dry before application. In all cases, the paint manufacturers instructions are to be followed.
