Its just flat matte dark gray.... It performed better then white during the day so i stuck with that until i could make the full black screen.

Is the material mostly available at 48" high or have you seen it even larger?

Does it seem like it might be thick or rigid enough to be applied directly onto a rougher surface like textured sheetrock or plaster without showing all the bumps?
Either way, it's definitely going to be easier to get a smooth result than paint, but it'd be great if it happens to be really forgiving.

You will be able to go larger then 48 inches & yes you will be able to put it on a thick substrate but there is a process to this method. Its not an out of the box material like the gun powder.

Stephen77 this looks very promising . Any idea how the uniformity will be on a large screen?

Thats what concerns me the most. It will probably need to be curved or be further diffused which would lower the gain. Diffusion is expensive & it limits your size so i will probably have to use a curved approach to help with uniformity. The viewing angle is narrow so i will definitely have to reflect the image back to the viewer Creating better uniformity & a wider viewing cone.

I'd you put the black sample in the center of your screen and look at it from about 10ft back/center..about how far to the left can you move before you think its too dim on the sample.

Ive done just that & the cone is fairly narrow & i wished like hell it wasnt because if it wasnt i would have something that would change the game. Even a curved full screen version of this material be absolutely amazing. Ive placed the sample on a far top corner & then watched it from the opposite corner to see it was to dim to view but then i gave it a slight turn towards me & it cleared right up. So a slight curve should do the trick.

With the sample at dead-center and facing straight forward, how far left can you watch from at 10ft back? This is pure viewing cone regardless of uniformity because uniformity can be fixed by the curve.

Measure about how many inches toward one side you can comfortably view, divide that number by ~16" and round down to the nearest whole number.
That'll give a decent estimate for how many people can sit side-by-side.

The width can be helped by a few things; seating at farther distances will allow a wider arrangement, so will a brighter image from a brighter projector or smaller screen.

Anybody want a Black Diamond 1.4 clone for a fraction of the cost But with better viewing angles & more contrast? BD is on the left & the clone is on the right. The uniformity is perfect & the viewing angle is as wide as it can get.

Is this a brighter version? The earlier pictures looked like the black DIY was much darker (in both shade and gain) than the BD1.4 but this last one looks dead-on for gain.
Top-layer change?

I'll take two..would love an outdoor curved screen to try in the shade!

Yes this is a lighter version. I may just use this myself if i can quit chasing the pop & contrast of the black material. The viewing angle with this stuff is amazing & the gain is right up there with the BD 1.4. Thats a rare combination. This would definitely accomodate a big family setting better then the black screen. Its also outdoor ready too.

I'm hoping you're about ready for the big reveal.
Regardless, can you comment about the layering procedure (assuming there is one) or in general give an idea how difficult/easy it'll be to make for the average aspiring screen owner?

Got the BD .8 screen sample today & did a few comparison shots. its a little darker then the 1.4 so its apparently better in regards to contrast. Cant make my mind up on which route i want to take so hopefully you all could give some advice. I love the black but the viewing angles are poor & the uniformity is in question. The BD clone has awesome viewing angles & the uniformity is perfect but it doesnt have the killer contrast/black levels the black material has. Also the ambient light rejection isnt as good as the black material either. I can increase the viewing angles of the black material but that will require me to dim down the picture some. So pretty much i have to choose between gain or viewing angles. Also the process of the black is much tougher & i will probably have to curve the screen. The BD clone is probably the most practical choice because the pros out way the cons but that one con is the biggest con of all & thats contrast/black levels. The BD clone would be an amazing screen but since i have been to the dark side or better yet the black side...im not sure if i could be content with anything other then the black material I have worked so hard to make. Here some pictures that give you an idea of what im working with. Also the whites are much briter on the clone then the black but you really cant notice until they are side by side. So what should i do? Leave the black the way it is & have a very small viewing cone or dim down the gain to increase the viewing angle which would ultimately lower the overall brightness of the picture. I know that wouldn't be to big of a deal in most cases but dimming down a material that is already dim to begin with can take a lot away from the picture quality. Or i could simply go with the clone & still have an awesome screen.

How wide is the curve? About the same or less than those curved 4k flat panels? If so that's not so bad. It would be neat to have the possibility of a plasma looking image much bigger than any real one.

I'd keep both projects going. The BDclone would be excellent for mixed-situation theaters with dark at night but a little light at other times.
The black screen can use its narrow cone and curve to be a ridiculously effective light fighter for those with sky-lights or outdoors or simply wanting daytime without curtains at all.
I think leaving the gain and diffusion as-is would probably be best.

As I watch movie or pc on my 113" 16:9 grey material screen, I thinking the "BD clone" might be just right for me for the near future.
Could you let us know what needed to make up this screen and hopefully won't be to hard for me to buy.

Thanks again for all your effort and money spent

Fix screen as have got now. I'm hoping the material used will allow for at least 110" 16:9 screen.

So ive successfully increased the viewing cone but it did slightly dim the picture. It was still brighter then my comparison gray screen so i dont think it will make much of a difference & i also think it will help the uniformity because of the added diffusion. Something that i think could get a little bit of the brightness back would be to ever so slightly lighten the shade of black. Im going to try to make it a few shades darker then the BD .8 without it being a very deep black that i currently have. I really believe its about hitting the perfect dark shade but not to dark. I want it dark enough to were the contrast pops like crazy from the black levels but not so dark that it cant produce a good white along with very poor viewing angles. BD did do a good job getting that perfect balance between light & dark because my black material obviously has better blacks (which i love) but BDs whites are much better. So that comparison sample of BD has inspired further r&d. I Thought i was about there but it looks like i have a little more testing to do until it beats the BD with contrast & white lumens.

Stephen77 I understand that you are holding your cards close to your chest but can you give us a hint on the total price for a 100" 16/9 screen, not counting the board and frame if possible.

Wish this was as simple as the gunpowder vinyl but its not. The Full Black material is quite the process so i really cant know how much it will cost. Seems like with each passing week i have to do something new to it before i get it just right. Im still a ways off from a full screen prototype of the black. The Clone is much easier because the uniformity & the viewing angles are already good. If someone would like a sample of that then maybe we could work that out. Just pm me. The clone is a balanced mixture of the 2 BDs .8 & the 1.4. The shade & the brightness is really close to the middle spectrum of both of those samples combined. So its probably close to a 1.1 gain or somewhere in that ballpark.
