The installation processes for fiber cement boards and wood strip wall panels (usually referring to wood veneer panels or wall panels) differ, requiring separate installation methods: "keel + dry hanging/nail fixing" and "clamping/nail fixing/adhesive bonding." Key points are as follows:
Fiber cement boards: Must be installed on a flat and sturdy light steel or wood keel frame (spacing ≤ 600mm), secured with galvanized self-tapping screws (edge distance ≥ 15mm, nail distance from wall panel ≤ 300mm, ceiling ≤ 200mm), leaving a 3-5mm expansion joint (3mm indoors, 5mm outdoors). Tighten from the center of the board outwards, slightly sinking the nail heads and applying anti-rust primer. Use a diamond saw blade for cutting. Before installation, the boards must be adapted to the site's temperature and humidity, with a moisture content < 10%. Exterior walls require waterproof caulking (using a special flexible caulking compound), while interior wall joints can be coated with flexible putty.
Wooden strip wall panels (including bamboo fiber integrated wall panels and solid wood/composite wall panels): Most use a snap-fit tongue and groove splicing method. First, install the starting strip + sealing moisture-proof strip on the ground, then install from bottom to top and from one side to the other by inserting the strips. Non-insertion edges (such as corners and finishes) are fixed to the wall with nail-free adhesive and 2.5cm drywall screws (with expansion tubes). Direct nailing into lightweight walls is strictly prohibited; wooden wedges or special connecting fasteners must be used. Leave a 1-2mm thermal expansion and contraction gap, and use PVC/aluminum alloy pressure strips for finishing (which can be fixed with VHB double-sided tape + dotted nail-free adhesive). The base layer must be basically flat (unevenness ≤ 5mm), with local leveling of uneven areas rather than full
framing.
Both types of wall panels require prior completion of water and electricity lines, base leveling, and moisture-proofing treatment (especially in bathrooms/exterior walls). Installation is strictly prohibited in damp, rainy weather or when the panels have not been aged for 24-72 hours. If the wood strip wall panels are "pure wood veneer" rather than engineered wood, a 40×60mm anti-corrosion wood joist (400–500mm) must first be nailed on, then fixed using a pneumatic nailing method (nailed into the panel seams). The surface must be coated with clear varnish/wood wax oil.
If "wood strip wall panels" refers to decorative wood trim (not whole-panel wall covering), then they can be directly fixed to the base layer using nails or structural adhesive according to the marked lines, without a joist.
Important: Fiber cement boards are heavy, hard, and brittle, requiring professional cutting and protection; wood strip wall panels are mostly "prefabricated integrated wall panels," emphasizing moisture-free installation and quick-installation clips-the two cannot be processed using the same method.
