Joining wall panels without glue is a technique that involves using mechanical fasteners, such as clips, screws, or nails, to attach the panels to each other and to the wall. This method is often preferred over using glue because it is less messy, allows for easier panel removal in the future, and does not require any drying time.
There are a number of different types of mechanical fasteners that can be used to join wall panels, and the best choice will depend on the type of panels being used and the desired look. For example, clips are often used for lightweight panels, while screws are more suitable for heavier panels. Nails can also be used, but they are not as easy to remove as clips or screws.
