In dry rooms, instead of nails, you can use glue.

The peculiarity of PVC panels is that when assembling they are interconnected and form a whole canvas. How does it happen? Previously, the starting angle is fixed on the crate. The first panel is inserted with a narrow mounting shelf into the groove of the starting corner, and the wide shelf is attached with nails on the crate. In dry rooms, instead of nails, you can use glue. All the following panels are mounted in the same way — with a narrow shelf are inserted into the previous groove and attached on the crate from the side of the wide shelf. The last panel is not fixed, but inserted with a wide shelf into the end corner.
