The installation of the main ribs for the exterior wall wooden panels also involves certain knowledge. Although the process is not very complicated, each step requires precise positioning.
First, it is necessary to inspect the wall where the wooden brackets will be installed to ensure it is level and clear any obstacles on the wall. Identify the horizontal reference line for installing the wooden brackets and mark it. This is to facilitate the installation of the keels. Then, we need to arrange and fix the keels. The keels are usually made of 50# lightweight steel material, or 2.5*3 cm square wood can also be used. The vertical distance from the keels to the ground should be 60 cm, and then use steel nails or expansion screws. The keels should be made of anti-corrosion materials (preferably those treated specially), and the keels around doors and windows should be laid to enhance stability.
Starting from the first layer at the bottom, use shot nails to fix the exterior wood hanging boards onto the keel. If using self-tapping screws, pre-drill holes with a twist drill. The nail heads should sink 0.5-1 millimeter into the wood. The bottom position should be treated for anti-corrosion. Then, apply putty to smooth it out. The distance between the nail holes and the board surface should be no less than 1.2 centimeters, usually 1.5 centimeters, and 2 centimeters at both ends. Repeat this process to fix the second and third wood hanging boards, and so on. When the width of the wall exceeds the length of the wood hanging boards, the interface at the same horizontal line should be on the keel and should not be connected in an unsupported manner.
The interface of the exterior wall wooden hanging boards should have a 3 to 5 millimeter gap. After that, the gap should be filled with adhesive. The inner and outer corners of the wooden hanging boards should naturally come together, leaving an appropriate gap. The top wooden hanging board should be bonded with sealant at the connection with the top eave to achieve a waterproof effect. When installing the wooden hanging boards at the doors and windows, they should be cut to match the shape of the doors and windows for installation to avoid through seams (which are prone to causing water leakage). The connection at adjacent wall corners should be sealed. Outside the wooden hanging boards, clean up the dust and stains, and apply a layer of acrylic paint.
