Whats the best paint to use? for a home made projector screen
Hi,

Been using a wall with white matt paint, but moving living room around soon and thinking of using a sheet of MDF and some paint, im sure i read on here somewhere that someone used some sort of silver flicker paint which gives the best light quality?

Anyone know what this paint is actually called?

Cheers

The best light quality is white matte. It's the standard reference but requires a powerful projector with lots of lumen.
Sometimes when in 3D mode, the projectors you are using may not have enough lumen for your taste.
In this case you can try to use high gain screen to compensate.
A higher gain means the screen will steer more light straight in front and not let the light bounce to the side. The basic idea is if you are in the screen's best angle, the image on screen will appear much brighter than it would appear on a matte screen.
The drawback is you can't watch such a screen from the side and if the gain is too high you'll start to see the brightness start to drop significantly when watching the sides of the picture : a phenomenon called hot-spot (very bright at center, dark around).

You must have caught a post from Tritosine, he's a fan of very high gain screens. I don't remember which paint he recommended but you should be able to find much more information at dedicated home-cinema forums which have DIY screens discussions, like avsforums for example.

Behr Silver Screen is what you want. There is a huge topic on it in avsforums. Just google it.

I used this for my screen on top of a couple coats of killz primer. Works great.

Consider buying fabric, rear or front projection. ( I'll pm you)

The fp silver fabric I bought and tensioned is MUCHH darker grey than the paints I come up with, and being dark grey, it rejects ambient light very very good and not lighting up my room at all. This translates to MUCHHH better percieved ANSI contrast.
The drawback here is hotspot (you won't see it), you won't see silver textures because its not that bright at 120hz ( you won't notice it).

Next step is buying rear projection fabric containing microspheres with anti glare coating (dark grey closer to black) and retroreflective properties ( gain: 3.2) , again percieved ANSI contrast and colors going to be improved like hell!! This material is in fact better than the stuff they ship projection TV's with.
This has no hotspot, and with a 65" screen , brightness should be close to naked eye view. Image quality must be top notch too.


Everything with grey or dark grey finish is mucho better than white, "white is the best" is such a bs*, ignore it.


*yeah, white is the best at showing:

-worst contrast characteristics
-worst colors due ambient light hitting screen
-darkest 3d and crappiest blacks

maybe it has something to do with completely light controlled cinema rooms, and completely non-light controlelr class rooms (for viewing angle), but it has nothing to do with home 3d, not relevant.

Any chance you guys could post a link to the fabric here? I'm just about to stretch a 100" 16:10 screen with BOC and will probably paint it with the avsforum Silver Fire 3.0 mix at some point, but I'm interested to see what fabric you're going with.

Thanks!
