Has anyone tried using Tile Board for a screen? I got my pj about a week ago and have been using blackout cloth for a screen, the problem is that the cloth is hanging from the ceiling in the middle of the room. So, air conditioning can cause it to shift and can become very distracting (especially during a camera pan). I thought I would take a look at using plywood or press board (very light and solid materials) to use as a backing for the cloth so it would hang straight. While I was at home depot I came across something that was called Tile Board, it is a thin and very light weight material that comes in sheets of 8' by 4'. After looking at it I thought that may work for a screen as is (no blackout cloth - just tile board). The surface is very smooth. Anyone know how this works as a screen? My only concern is that it may be to glossy. If it is too glossy, does anyone know of a paint that would give it a nice matte finish, or perhaps a paint for making it silver?
