Technically yes, but as a method of securing them to the wall to hold the specified weight, then NO, this is not recommended.
Adhesives like liquid nails and other similar products (stronger ones) will certainly secure the panel to the wall but we cannot in any way guarantee that the panel will hold any weight.
On a plasterboard wall, glueing the panel to the plaster is simply glueing it to the outer paper layer.
We recommend that you use our Installstrips. If you don’t want to invest in installstrips, you can screw through the panels and into your wall.
