Confirmed or just a guess ?

Painting a wall can have as much gain as a manufacturer screen. A lot of them use gloss to up the gain. The popular DW has a high gloss. The only other way to adjust gloss is to use beads or other pigments besides titanium dioxide. Sunstone's screen is probably as good as most manufacturer's screens if not better.

i only brought it up because youall say that proper screen size for crt is 100inches or so .well i'm saying it might be your screen . i get 150inches easily, so my screen must be better .and to pay 3000.00 for a 135inch 16/9 .look just giving the info so you don't have to be stuck on a small picture, crt can do 150inches easily

Tom Believe it or not Light passes through the Studio Tek 130 surface as well,
While my HT is panted matt black I placed Black Fidelio Velvet on the wall directly behined my wall mounted Stewarts Lux Deluxe fixed Screen so as to stop any chance of light reflecting off the wall back through the screen.....
Cheers...

I also put Black velvet on the rear of my fixed and stretch mount Stewart 1.3 screens.

I think the Edition of the Black Fidelio velvet placed behined my Studio Tek 130 improved the picture quality & depth..
Did you notice any difference in picture quality after you installed the Black velvet Tom?..
Cheers..

Unless you have some gain measurements and color accuracy measurement I wouldn't assume your screen is "better" than the pros. What I think is much more likely is you are happy with the picture you are getting now which is all that matters but others might find it a bit dim at that size. There is really no right answer to the screen size question. In my case the "punch" from the higher gain screen has made a huge difference. I didn't realize what I was missing with my previous unity gain screen. I wouldn't want to lose that punch by going with a larger screen and I suspect the artifacts of a higher gain screen than what I have got would also cause me issues. Bottom line there is really no free lunch with screens, screen size or brightness. It is a pick you poison situation.
BTW, I have seen about a half dozen home made screens and they were at best equal to a standard unity gain screen (most were worse). I have never seen a Wilsonart one though and I have heard good things about it. If I hadn't found a cheap Stewart that is probably the way I would have gone.

He didn't say "better" I did. If you are a good painter, then you can spray a smooth finish. Most of the unity gain screens are using titanium dioxide and some manufacturers are upping the gloss to achieve higher gain. I am not sure, but the Stewart may be using a combination of gloss and Barium Sulfate in their screen. I doubt the color accuracy will be that much different between a good white paint and a manufacturer screen (Stewart not withstanding). Of course, if one wanted the extreme accuracy that Barium brings, then they could buy the pigment and mix up their own paint.
As for size, Clarence proved years ago that CRT could go large. One just has to decide how bright of an image they can live with and proceed accordingly. Most of the big screens are producing low teens to single digit ft/lmbs. For me, I prefer the brightness around 20 (and would love to go higher to mid 20s). That means small screen or Torus. I know I have been saying it forever, but my next screen will probably be a Vutec UHG screen clone. Oh, I should mention that even if you don't see the uniformity issue with a higher than unity gain screen it is still present.

Actually if you reread his quote above which you quoted he said "i get 150inches easily, so my screen must be better...". That sounds like a better claim but as I said as long as he is happy that is all that matters. And yes I have seen some home screens that were sprayed/rolled that looked good but no better (or worse) than my Carada Brialliant White (which I consider a decent but not great screen). I absolutely agree with the right, skills, research and knowledge once can make a heck of a screen. And yes you are right on the uniformity issues I do see it on an all white screen with my Stuidotek but so far not on actual video. So far it is a trade off I am willing to accept. As I said previously there is no free lunch (pick you poison) when it comes to screens.

2 pages extolling the virtue of screens and the OP hasn't checked back in even once, and the thread rages on.

my image is bright ,on the carada i would had to run the contrast and brightness higher just to get 100inches. and i set my contrast brightness color up by sypder tv pro .so it's not dim ,it had me turn it down and my eye fatigue went away . i had it to bright. and i set my metal studs and all ,i set it 5 inches infront of the main wall so could make it as close to perfect as possible. when i used the hw15, i had to run it in low mode and shut the iris down to 35. for 150 inches also

It sounds like you are getting some gain from the gloss. If you like it that is all that matters, but it does come with a price. For some, uniformity isn't that big of a deal as for others it is easily noticeable.
As for dim and bright, that is a matter of opinion. Just saying dim and bright doesn't tell me anything. I saw 20 ft/lmbs on an 18 foot wide screen and thought it was great. For some that is to bright and others it is way to dim.

The OP probably forgot he posted a screen topic in the CRT forum and not the screens section.

paint comes in sheen grades gloss being the highest . i used matte plus eggshell mix . eggshell is the next step up from matte . you got flat,matte, eggshell ,satin, semi gloss ,gloss or high gloss.if i use strait eggshell it will hotspot and have uniformity problems ,i have neither. i think it works well is because it doesn't absorb or let light pass through it. i even tried silver paint and it looked like a mirror when i turn on the projector and man what a hotspot! looked like a flashlight shining in a mirror
