1.  Level the Starter Fastener Row: Begin by installing the bottom row of fasteners. Ensure they are perfectly level using a spirit level.

2.  Install the First Board Row: Position the first row of boards level. Engage the groove lip on the board's lower edge securely behind the fastener tabs.

    *   Verify the fasteners are fully seated within the groove to keep the boards level.

    *   If needed, carefully tap the boards into place, ideally using a rubber mallet.

    *   Important: Always secure board ends (end joints) over a structural support (joist/beam) using at least 2 fasteners.

3.  Add the Second Fastener Row: Place the next row of fasteners directly onto the top edge of the first installed board row.

4.  Install the Second Board Row: Mount the second row of boards onto the newly installed fasteners.

5.  Continue Installation: Repeat this process (adding fasteners to the top edge of the previous board row, then installing the next board row) to cover the entire surface.

    *   Maintain level alignment of all fastener rows throughout.

    *   Preserve a minimum 5-10 mm ventilation gap at the edges.
