A common question often asked is will the plastic stay up when it gets wet. A simple answer is sometimes yes, and sometimes no. The amount of water used and the humidity play a major role in causing plastic to fall. An easy solution to this is to staple the corners of the plastic. Corners are most likely to fall first before anything since a corner is the weakest point. The best way to do this is to use a small piece of cardboard and 3/8″ staples from a T-50 stapler.
