Home Theater #12 - Sheetrock Screen

After quite a bit of research, I have decided to go with a sheetrock projection screen. Here is an image of one I found on line...


Reasons for going with this type of screen as opposed to a purchased or cloth DIY one:
- Cost is low. This screen will cost $40 max for a 100" diagonal size (80x60). To purchase anything of that size with a reasonable level of quality is at least $500. I did find one online for about $150, but the reviews on it were mixed.
- Sheetrock is easy. This will take one and a half sheets, with just one seam to tape.

I am going to use Home Depot's Behr flat paint for the screen. They have a light grey color called "Silver Screen" for this purpose. The examples I have seen online show very sharp images with good color. I am still not sure about adding a coat of matte sealer to the flat paint - there are varying opinions on it.

I'll be building this screen in a 4:3 size, since we watch TV on our theater, as well as movies. I doubt broadcast TV will be going to 16:9 for quite a while, so I am not worried about changing it any time soon.

Also, I will use a couple of layers of 1x4 to build the support frame. This will easily give the sheetrock full support, plus offset it from the wall by 2 inches, giving it a solid shadowline.
