My Glidden Diamond 450 (White) Screen

Well, it's finally time to paint my screen white. Going on my failed efforts to design a new screen paint, I'll be using Glidden Diamond 450 Titanium White in a velvet matte sheen. I'll be editing this post soon to add color data from previous threads/posts. After I'm done I'll do new subjective and objective analysis.

My current screen is Silver Fire HG V2 @ 138" diagonal. My 8700UB just doesn't have the power to light it up properly in THX mode.

Thanks to Harp for moving posts on another thread here!


Here's the original post I did on testing the Glidden:

Here's some data from some testing I did tonight.

I did all the maximum cd/m2 tests without touching the meter between materials. I then lowered the meter aproximetely 25 or 30 degrees for another cd/m2 reading and ran all the materials through again, also without touching the meter between readings. I used an Eye1 Pro and HCFR. I used BabelColor CTA and the Eye1 Pro for the color data.

The first number is cd/m2 with the sensor adjusted for maximum reading. The second number is cd/m2 with the meter lowered about 25 - 30 degrees. the third fourth and fifth numbers are the RGB values. The last number is deltaE from perfect neutral. A deltaE of less than 1.0 is considered perfect. Less than 3.0 is considered to be so close as to be indistinguishable from neutral by the human eye, at least according to what I've read.

I've included readings from my SF HG screen for reference. Check this thread: http://www.hometheatershack.com/foru...velopment.html and you can see the hotspotting on that screen. Then note the variance between cd/m2 high and low numbers. I've included some data from some Cream & Suger paint that I have. Please note that we have determined that the sample I have is a first version, and not representative of C&S in general. There were most certainly some issues either with the base or the silver paint. But you can see how it's possible to have ZERO variance in cd/m2 for normal viewing angles. The cost, of course, is low gain.

Titanium Sintra:
37.5 32.2 246,246,242 2.36

Glidden Diamond 450 Titanium White:
36.35 31.6 245,246,243 1.43

behr 1850 UPW:
35.3 32.05 249,249,246 1.95

Sherwin-Williams ProClassic Smooth Enamel Satin Extra White:
31.25 29.5 240,241,236 2.58

Carrada Brilliant White 1.4 Gain:
36.1 30.8 242,242,236 3.22

C&S:
22.6 22.5

SF HG:
33.1 22.5

One note: This really opened my eyes. Comparing the Behr and the Glidden visually, I would have said the Behr is slightly brighter. The slight color variance can fool the eye; it really truly takes instrumentation to tell the tale.

Visually, I can detect absolutely no hotspotting with the Glidden, Behr, or SW. The Carrada sample is too small for me to really tell. The Titanium Sintra is possibly warm in the center. I don't believe a full screen would show a hot spot, but I guess it's possible. I just don't have the experience to tell for certain.

I wanted the Titanium Sintra to be the clear winner, but I can't say that it is right now. I think the extra 3% brightness it has over the second brightest paint--the Glidden--is worth investigating. (At least for me.) But it isn't there yet. The Glidden is only 3% dimmer, and is off the shelf and easy to apply.

Personally, I think the Glidden and the Behr are both better choices than the Carrada BW sample I have. Similar gain characteristics and more color neutral. I'd give a slight nod to the Glidden over the Behr, and I'd rate the Sherwin Williams a distant number four. Distant at least when you consider how close the top three are.

So, here are my ratings:
#1 Gliddon Diamond 450, Titanium White, Velvet Matte
#2 Behr UPW 1850, Interior Flat Enamel
#3 Carrada Brilliant White 1.4 Gain Manufactured screen.
#4 Sherwin-Williams ProClassic Smooth Enamel Satin Extra White

Titanium Sintra: Not ready for release.

BTW: I did do reflectance curves of all the white paints, they are all equally good with the Behr being the brightest white, N9.78. I'm just too lazy to post the graphs.
BTW, I started a thread for the review of the Epson "Light Power Edition" filter for the 5010/5020 6010/6020 here: http://www.hometheatershack.com/foru...#axzz2DhAgyp8t

I painted over silver fire. I went with harpmaker and mechman's recommendation to sand the SF a lot before using a primer and then finally a flat gray paint. My results are awesome, I don't notice any loss in brightness but I get better contrast, no hotspotting, no sparklies, etc.

Don't let anyone tell you that you can't use a roller, I did and it looks crystal clear.
Hey there! Carp, what primer did you use? I'm painting my SF screen right now. I sanded the stuffing out of it, cleaned it with rubbing alcohol, and let it dry for a couple of hours. Then I rolled on the first coat of Kilz Premium. Wow, it doesn't look so good. I'm thinking one more coat, then wet sanding it. Trust me, it's going to need sanding. I'm hoping it's going to work at all. It's almost fish eyeing, but not quite. I'm almost thinking just sand this coat then switch primers...

I really don't want to hang a new sheet of Sintra. It's a pain to get home, and I have styrofoam insulation bonded to the back. It looks like I may have too though.

Re: Silver Fire

Update: The second coat looks better, full coverage with no tendency towards fish eyeing. Wooh! Unless somebody recommends different, I think I'll let this coat dry overnight and then sand. It's still pretty rough.

Re: Silver Fire

I just used Kilz 2. Don't worry, it will look better. I did 2 coats of primer and 3 coats of paint. I could have been done in 2 coats but I had a drippy that I didn't see until it was too late.

Go slow and let the roller do ALL of the work. I didn't put any pressure on the wall at all.

Re: Silver Fire

Thanks Carp! Did you sand at all? If so, how long did you let the primer dry?

I'll be spraying the top coat; the Glidden Diamond 450 Titanium white finally. I rolled the primer 'cause I can always sand it. But it's just easier for me to spray the top coat. I have a take down paint booth I made out of PVC. It takes me about 5 minutes to set it up is all.

Thanks again!

From my comparison with the Carrada Brilliant White, I'm guessing 1.2--but that is only a guess. I need to get a sample to Mech for real testing. When I compared the two with my i1 Pro, the Glidden was just a teensy bit brighter than the Carada, and a little bit brighter off angle too. More color neutral as well. Here's a link to the thread, my test is a ways down the page. http://www.hometheatershack.com/foru...#axzz2DI5yczfp

Re: Silver Fire

I just got my Epson 5020 and I'm using BW but with 3D the picture is a little bit dark. Thinking about getting something with a higher gain to help. So will this paint help with 3D thanks.

Yes, the Glidden will be quite a bit brighter than Black Widow. However, if your room isn't treated with dark walls, ceiling, floor and furniture; white is not a good choice. I'm going with the white, but I'm also going with charcoal ceiling and carpeting, black furniture and black velvet drapes on the walls...
