Cool Screen paint for light controlled room with Sony 600ES 4k?

I have done a theater in each house I have lived in but this will be my first painted screen. The Aggie Theater in Birmingham begins....


Thanks for all the info (in advance)

I recently completed such an installation using a 600es 4K, in what was called "Light Controlled" but was in fact a room where some light would always be present. How goes your more exact depiction?

I used Silver Fire v2.5 2.0 with an additional 8 oz of UPW (Interior Enamel) to create a perfectly smooth, blemish free surface ideal for getting impeccable results for 4K resolution images. Such a mix / application will not let you down if and when you ,ight "have" to watch some content with some degree of lighting going on....but when the lights go off, the resulting image (even in Low Lamp Mode) will look every bit as spectacular as a 65" UHD TV.

So things to also know....Screen size...what type of Substrate? Decided on Throw distance (related to screen size)

There are of course some simpler Paints that will work effectively enough to not disappoint. But bright white Paints will do nothing to preserve contrast delivered to the screen if it is countered by any room conditions. Basic Grays will provide some help, but at the cost of maintaining gain.

Birmingham, eh? Just a wee little ways from North Mississippi (Byhalia)

The screen is looking like 130" wide. I want to do the whole screen are though so I can do 16:9 and 2:35. The substrate is sheet rock and here is the pic...

Be sure that those joints are feathered out at least 8" on each side, and then the entire area skim coated with Compound (2x if necessary) and lightly sanded. Priming with a Primer called "First Coat" (2 coats), that is applied via spraying will result in a almost glass smooth surface after just a very light sanding.

Here are my pics after the sheetrock is complete:


All of the paint is sitting there ready...now for the questions!


1. The screenwall is all sanded mud so...do I prime that before I spray it with SF 2.0?
2. How many coats?
3. I am using the Wagner 0518080 Control Spray Max HVLP Sprayer so just use the nozzle/tip that came with it?
4. What pressure level do I use?


Thanks!

[QUOTE=Texas Aggie;29539170]Here are my pics after the sheetrock is complete:


All of the paint is sitting there ready...now for the questions!


1. The screenwall is all sanded mud so...do I prime that before I spray it with SF 2.0?

Always! Drywall mud must be sealed with Primer. Thin the primer with approx. 4 oz water per quart and spray on primer "Duster Style".


2. How many coats?

At least 3 Thin Coats, or until Primer looks fully opaque and even. It is a good idea to sand the next to last coat of Primer because the larger droplets tend to dry with more induced texture.


3. I am using the Wagner 0518080 Control Spray Max HVLP Sprayer so just use the nozzle/tip that came with it?

I wish you were not. The 2.5 mm Tip really throws out a lot of paint in large droplets, so real care must be taken to use a very quick Duster technique. It would be better if you made this purchase.
http://www.amazon.com/Wagner-Detail-...ish+spray+head

4. What pressure level do I use?

If you use the stock tip, probably 5-% pressure. It will be a lesson in practice because you simply must find the best blending between paint thickness, pressure, and Duster speed / distance.. Those considerations are what made the use of any of the Wagners except the original Wagner:

http://www.amazon.com/Wagner-0417005.../dp/B000DZBP60
.....a more risky proposition, and why the switch to the Graco / Earlex sprayers and 1.0 mm needles was made some time ago.

I myself adapted a Max Turbine Hose to fit a Graco Head so I could pump out more pressure through a 1.0 mm needle assembly. Before that, I always used the smaller Wagner Head....not the stock 2.5 mm, which is intended to allow one to spray Latex paint using less thinning.



Thanks!

Your welcome. At least I hope you still feel congenial after the above revelations.

Added.........

Since your using a SONY 600ES 4K PJ it is absolutely essential you achieve a ultra smooth finish. Feel free to contact me for "ANY" support and advice you feel you need. Ask before you squirt.....not after any issue/s arise.

Any well done SF screen is to be considered as being "4K Ready", contingent upon the quality and level of smoothness of the application.

ok Mississippi Man came and did his magic. I got my Sony working last night finally and it looked amazing.....simply amazing.


My only problem is that I think I have changed my mind and will NOT do a constant height 130".


My space for screen area is 132" by 70" and the 130" 2:39 is just too small given the area...(see pics)


So I will now have to mud...sand...spray the SF 2.0 to make the 1:85. All good though considering the image quality via 4k and SF 2.0

Might be able to cut in the Taped areas with the paint you and I both have left. Also gives a chance to correct a couple small blemishes at the same time.

I would not suggest redoing the entire screen though.....

BTW...that image looks pretty good considering you have both Floods going.
.....and wasn't that second shot in the multi-shot grouping taken under Flash? If so, that is really incredible.

It was with flash which is why I posted it...


I will have to mud the taped area because it is significantly lower. 7 coats of paint lower

Yes, that was one of my slower "Finish Coats"....less a "Duster" than the first 5 applications.

But that is about as slow as such a coating can ever be applied...and even then only because my own experience led me to accept the possibility.

Yeah....I can rush things a bit by applying slightly heavier coats than I advise others to do....but that's me. For others, to assure that no runs, sags, or orange peel develop, that is why a focus on "Dusting" is to be strictly adhered to.

Wow....130" diagonal SF v2.5 2.0 with a 1300 lumen PJ and the screen getting washed with a Flash. That amounts to having 1.2> gain without washout or gross hot spotting under directed Flash. And the walls & ceiling are still "white Primed" too.

Yes, but be sure to sand the leading painted edges down to a tapered edge before you apply the mud. It will then take less, and feather out much easier.

Another interesting thing to take notice of is the White primed stripe around the screen where the taped off area boundary was. It shows both the lack of contrast and color that the white primed surface presents...as well as the lack of any degree of ambient light resistance whatsoever, as well as show just how much darker the SF screen itself is than such a Matte White. And even at that it's still only a SF v2.5 2.0

But we all knew that would be the case, didn't we.

And lastly, the image shown seems to be closer to being 120" x 68" ( 138" diagonal)
All the more incredible.
