How to install external wall hidden nail sandwich panel?

Installing external wall hidden nail sandwich panels requires careful planning and execution to ensure a secure and weather-tight installation. Below is a step-by-step guide to help you through the installation process.

1. Measure and Cut Panels

Measure the height and width of the wall sections where the panels will be installed. Use a utility knife or metal shears to cut the hidden nail sandwich panels to the required dimensions, ensuring clean and straight cuts.

2. Mark Installation Points

On the building’s framework, mark the locations where the panels will be attached. Typically, fasteners are spaced every 600mm to 800mm along the vertical edges and at intervals along the horizontal seams.

3. Install the First Panel

Start at one corner of the wall. Position the first panel vertically, ensuring it aligns with the framework. Use a level to ensure the panel is plumb before securing it.

4. Fasten the Panel

Secure the panel to the framework using the hidden nails or screws. Drive the fasteners through the pre-drilled holes in the panel into the framing. Ensure that the fasteners are tight but do not over-torque, as this can damage the panel.

5. Install Additional Panels

Position the next hidden nail panel adjacent to the first one, ensuring it overlaps correctly if required. Continue fastening each panel in place, ensuring that all panels are level and securely attached.

6. Sealing Joints

Apply sealant to the joints between the panels to prevent water infiltration. Use a high-quality exterior-grade sealant. Ensure that the sealant fills any gaps thoroughly to create a weather-tight seal.

7. Install Flashing (if necessary)

If the design requires, install flashing at the top and bottom edges of the wall panels to direct water away from seams and joints.
