I.Plywood can be fastened to walls using adhesive.
Yes, but it is not recommended.
If used to fix lightweight plywood to a wall, you can use wood glue or a wood adhesive. For example, when renovating and wanting to attach decorative items to plywood without drilling holes, you can use adhesives such as glass glue, white glue, or structural adhesive.

For heavier loads, we do not recommend using adhesives for fastening, as adhesives take a long time to cure and may detach over time. Instead, we recommend using self-tapping screws to fasten the plywood to the wall, which is a more reliable option.
Two. important considerations for installing wall coverings on plywood
1. It is not recommended to install plywood on walls adjacent to bathrooms or in areas prone to moisture, such as kitchens and bathrooms. If plywood is installed in these areas, it is necessary to leave appropriate expansion joints to accommodate the thermal expansion and contraction of the flooring.
2. Before installing wall panels on the particleboard, it is essential to level the wall surface to prevent unevenness from causing the panels to warp or ripple, which would affect the appearance.
3、Before installing the tongue-and-groove flooring, if the budget allows or there is surplus waterproofing material, apply waterproofing agent to the flooring area to prevent moisture from affecting the boards. This is especially important in areas where waterproofing is not typically applied. The wall surface must remain dry to prevent moisture from penetrating the boards, which could cause them to warp.
However, it is recommended to apply a waterproof layer to the bottom of bathrooms and kitchens, which are prone to moisture.
4、When installing large areas of wood panels on walls, accurate edging is crucial. Currently, most people use frame edging. The longest frames available on the market are only 3 meters long. Therefore, if the wall area is long, it will involve interfaces, and the workmanship required for interface treatment is high. It is recommended to choose branded wood panels, as they are typically edged more accurately and aesthetically.
