Re: Cream&Sugar™ Ultra

I'm getting ready to do my third iteration of C&S (my second of Ultra), as my theater is being re-built due to structural repairs to the building.

My screen size is going up to 11.5' wide, so I've upped my recipe to two gallons each of Valspar and Liquitex, just to be sure I have enough to cover the 80 square feet this will be.

I've bought a new, much brighter, projector, a JVC DLA-RS440, since my old Panny won't be bright enough for the larger image, so I'm wondering what color to paint my side walls and ceiling.

Flat white walls and ceiling worked in the past, but the side walls were six or so feet away on each side and the ceiling was a few feet above as well.

Now the side walls will be about a foot or two away, and the image will go up to the ceiling.

Should I go with grey walls and ceiling? How dark? I don't want the room to be so dark during a film that I can't see my snacks!

From reading earlier posts in the thread, it appears that the silver paint darkens the mix, so if I want to compensate for a projected image that's 69% as bright (because it's larger), to increase the gain by 44% I should use 1/1.44, or 69% as much silver paint as white paint.

Would this work, and is my math correct?

By the way, while this thread says it has 18 pages, and 176 posts, I can't get past page 16 and this post (#158) - whether by using the arrow link, the 17 or 18 links or the Last link on the first page. Incrementing the page number in the url doesn't work either - whatever I do, it takes me to the top of page 16!

This is true in both Firefox and Chrome, by the way.

Re: Cream&Sugar™ Ultra

I'm back for recommendations for my third screen painting job. First time was the original Cream and Sugar, second time was C&S Ultra.

I'm going to a larger screen (from 9'6" wide to 11'4" wide) by turning my theater sideways, which means an image only 69% as bright (9 foot/lamberts instead of 13 with my old Panasonic PT-AE2000).

Before realizing this, I bought enough Liquitex Basics Silver Acrylic for the job, since last time I had to wait a few months to get it!

Is it possible to make a brighter version of C&S Ultra to compensate - like by increasing the ratio of silver to white paint? It looks like I'd need a screen 44% again as bright. Should I use 44% more silver or 44% more white paint to do this?

That's good to know it handles the irregularities well. My main concern is with bright content highlighting the light textured finish on my wall. Putting an image up there now with the light tan color the builder used, looks remarkably good. As long as the C&S paint didn't highlight the texture at all I would be perfectly happy. Even while wearing my glasses, I could hardly see the texture from my seating position.

Do you think a couple of coats of primer would help "soften" the knock down texture before using the C&S?

It basically looks like this:

That's much more deeply textured than my wall - which is basically drywall (powdered plaster between two layers of cardboard).

I'd suggest a layer of spackle over the whole wall to fill in the irregularities. You might have to build it up with a few coats to get it smooth - but that would be a lot easier than trying to sand the whole wall smooth.

Then primer coat it with Kilz (I used two coats) and paint two or three layers of C&S.

I rolled mine on my wall, which is just existing drywall, with all the surface irreqularities from dinging and patching. I didn't sand it except a little where it had been patched. No problem with the metal paint being irregular. (I'm not willing to spray in an enclosed room with no ventilation, particularly since anything in the air would get sucked into the projector and mess it up!)

I've been using C&S for years, both the original formula many years ago and the current version two years ago after the wall got dinged by things falling against it.

I use an LCD projector.

PS Before the paint was dry, there were sparkles, but that went away once the paint had finished drying the next day.

Did you roll yours or spray? It seems like this would probably be a rollable mix as it's not that aggressive as far as the metallic aspect is concerned. Also, do you know how forgiving C&S Ultra is with surfaces that aren't perfectly smooth? It seems like in general the more silver, the flatter the surface must be in order to get good results. With this being a fairly light mix I'm hoping I can just prime and paint without having to sand a bunch.

I sprayed mine on a black out cloth that I got at my local Joann shop for pretty cheap. Having said that, my surface was pretty smooth. Like with any other paint, I would assume that if the surface is not smooth, you will be able to see the imperfections from up-close. I am not sure if the silver will bunch up more on the uneven surface or not.
