It is really difficult to remove the lamination because the plywood is fixed to the wall and then it is glued to provide protection. In this case if you have any problem and wish to remove, it will be time taking. So the only solution is to cut through the plywood as there is no other option left. Before starting, wear your goggles and gloves or the small pieces can get in to your eyes. Cutting can be done by a circular saw so get one which has sharp blades.

Estimate the thickness of the plywood and accordingly begin work with the circular saw. You need to apply pressure so that it can be cut easily. Prying is also done to provide a finish to your cutting. So continue cutting it unless you have completed your work. You can pry the cutting to give a cleaner view. So you can find a way to get your lamination removed using specified tool.
