Re: Black Widow Ultra™ Development

Welcome to HTS.

According to the calculator at PJCentral, you'll have roughly 40fL at the screen. That's incredibly bright so you could go as dark as you would want. I'd recommend mixing the AAA with an OTS Neutral tinted for N7. Dover Gray (N7.3) or Granite Grey (N6.7) would be your options. I'd recommend a decent paint - not a Behr product. And get it in a matte or flat enamel finish.

As for the primer, just use Kilz.

Thanks for the input. You are right about the projector being really bright. When I got the projector I was living at a different house and the living room would accept a much larger screen. Now it's a bit different. So I've gotten to thinking about how to make the screen larger to drop the brightness (and duh larger screen) which leads to my next question. How did you arrive at 40fL at the screen translating to a N7 paint? Just so I don't have to keep asking every time I decide to change the screen size.

Re: Black Widow Ultra™ Development

40fL is using a 1.0 gain screen. A N7 BW Ultra would probably be around .7 gain.

And I forget that Yiannis has a database of a lot of these projectors!

Re: Black Widow Ultra™ Development

I'm new to the home theater world and learning where I can, I recently put up a BenQ w1070 on the wall in my apartment and wanted to put down some black widow projector screen paint...

My throw from my projector to the wall is about 150" and a diagonal display of 135". There's one window in the room and we use some lighting in our apartment. My walls are currently painted a medium shade of grey and the image brightness isn't too bad for the light we sometimes use.

I have some AAA showing up today and was at lowes last night checking for the "valspar ultra premium gladden vail" paint, only to find that valspar no longer makes the ultra premium paint...

My question is, what brand and shade of paint should I use with AAA?

Re: Black Widow Ultra™ Development

If i were you, i would go with Benjamin Moore's Tundra as a base. Veil is too dark for a big screen like yours. (135'')

Snowfield by Glidden should work well too.

Re: Black Widow Ultra™ Development

Went with valspar signature satin snowfield....two thoughts....

1) with 1/4" nap roller, I can see roller marks. Should have sprayed it on. What small spray painter can spray this paint on? I may redo it.

2) I think having used satin paint, I think I might be hot spotting....should have stuck with flat or eggshell?

Re: Black Widow Ultra™ Development

You should never use anything above matte or flat enamel for a screen. The satin base is why you are hot spotting. I'm sorry to say this but it's time to repaint.

Figured...how washable is flat or matte? I have kids and they like touching walls. I am considering repainting with a spray gun vs roller anyways, anybody know what smaller spray gun can be used to spray without thinning the paint?

Any paints with metallic mixed in like this will require a pretty gentle hand for any cleaning no-matter what paint you mix with, but the flat/matte-enamel is a cleanable/durable "flat".
If the kids are old enough to understand certain concepts, it might help to explain to them that touching that particular wall might "break the big TV"..which would lead to them no-longer being able to watch said TV.

Most of the newer Wagners (around $60-75) use 2.0+ tips which work with unthinned paint.

Otherwise, I had solid luck using the $50 Wagner Opti-Stain which IS meant for thinner liquids by simply adding 5oz-8oz of plain water for every quart of paint.

The higher gloss you used likely exaggerated any roller-marks in the paintjob as well as the hotspotting it adds, so using a flat/matte together with the AAA-fine should give noticeably better results whether you spray or roll.

Simple
