I'm usually using removable adhesive putty to fix stuff on the wall (mainly plastic I'm writing on). But this time the sticks don't stick on the surface because of a condensation issue (rock issue).
I can't use pins (too hard and would damage the wall: thin layer of plaster on old rocks), I can't drill holes for that (I would need 10+ holes per plastic and the landlord…).
I need to find a cheap and removable solution that would stick on my wet wall.
Any idea?
ps: the question is not about drying a wet wall.

If you have sufficient space, and in this case, it's not all that much, you could consider a modified lean-to for your purpose. A horizontal pole from which the plastic is suspended with a vertical pole at each end. The vertical poles would be vertical referenced to the horizontal sheet suspension pole, but not-vertical referenced to local gravity. Orbital dynamics are not considered in this example.
The poles would be longer than the distance from ceiling to floor and would not have to have much of an angle to keep the horizontal pole against the wall. The bottoms of each pole should be braced or have a rubber/high-friction end to keep them from sliding out. If the span is severe, it may be necessary but possibly undesirable to have a center support as well.
