I am mounting soundproofing panels on a concrete wall in an older building. The walls are, of course, not entirely straight and also not 90 degrees to the floor.
The first panel was mounted so that it followed the wall instead of being completely vertical, to avoid the innermost vertical slats on the panel becoming wedge-shaped. Unsure if that was smart.
The last panel on that wall will obviously not fit exactly, partly because I don't expect completely parallel walls and partly due to that idiot Murphy!
I can measure the distance from the second-to-last panel to the wall at the top and bottom and cut the last panel with a straight cut, but ideally, I would like the panel to follow the wall where it bulges (not much, but a few mm). How can I achieve that?
To complicate matters further, a cut-out must be made in the last panel so that a power outlet is not concealed. Any tips for ensuring the cut-out is in exactly the right place? I have a couple of ideas but they're not foolproof, and I'm open to more suggestions.
