Prepare the tool and material as seen on the pictures (extruding gun, solvent free contact adhesive). Apply the adhesive on 4 corners and middle on the back of panel. In all cases insert the panels exactly following the instructions of the particular adhesive.
Apply the first panel on the lined top middle position, then go ahead with the neighbour panels by the same way. When applying on the wall press a little bit, around 15 seconds – depends on the type of adhesive – to make sure of no gap between. When the size of the wall won’t match the panels, cut the panels by knife as need.
