Fixing screws: Require 15 pcs per square meter cladding

Installation Steps of Composite Cladding

Step 1: Fix the joists according to marked distance. The best span between each joist should be 300-400mm.(Remark: the first joist should be installed min. 20mm from the floor)

Step 2: Screw starting clips to make sure the first cladding board is straight, so the cladding lines up perfectly.

Step 3: Put the first cladding onto the level starters, then pre-drill a hole on the cladding, the length of holes is suggested to be 15mm, and the width is depended on the cap of the screw ( Noted: The cap of the nail should be larger than the width. ) The span between holes should be 300-400mm to allow expansion & contraction.

Step 4: Once secure the first one, place the next cladding board in place and repeat this process, checking the level before each board is fixed. The screw will be invisible during the installation. Fix all boards until the top (or side for vertical) edge of the wall, you may be required to shape boards around doors and windows.

Finishing Steps of Composite Cladding

Install a Fascia Board to finish off and cover the last cladding board.
