Black Widow Ultra paint

Hello,

I have a 120in Silverfire 2.5 screen I painted 7 months ago and i'm very dissatisfied with the result. One of my issues is sparkles on the screen. I'm not sure what causes this but it's real noticeable when there is a bright white image. I watch a lot of hockey and the ice looks like a twilight vampire in the sun.

Projector: Benq W1070
Throw/viewing Distance: 11'4"
The walls and ceiling are painted black with no ambient light.

I'm thinking about doing a Black Widow Ultra screen, do you think this would give me the best results? What grey tint do you recommend?

Do I need to do anything to my Sintra board or can i paint ontop of the SF?

Thanks for the help.

What brands of paints have you access to?
How many hours on the lamp?
Is 1070 calibrated or not?

Re: Black Widow Ultra paint

I live in Dallas, TX so i'm assuming I can get any paint you guys recommend. I've seen the Valspar Signature in matte finish and shermwin-williams duration matte recommened alot I can get both of those, which one is preferred?
The lamp has around 450 hours.
I've calibrated the projector with Disney WOW

Let me know if you have any other questions.

Personally, i would go with a N.8.5 shade of gray for your 120'' screen.

Re: Black Widow Ultra paint

I am looking into using a piece of wilson art laminate. I think the people suggest designer white. It has some very good reviews but may be more challenging to install. There is lots to read on the subject!

Re: Black Widow Ultra paint

I'm new to this forum and based in Dublin, Ireland so hello. I decided to go ahead over the weekend and paint a Black Widow Ultra screen directly onto a bare wall. Here's a list of the materials/process I used:

- Turned on Projector (Benq W1070 which is ceiling mounted at about 9' from wall) and selected test pattern, then I masked the edges of this with 1" masking tape which gave me abut a 140" screen
- Using wall filler and a 1" scraper I filled any pits or holes and left this to dry for one hour & using a medium sandpaper I removed any lumps and bumps
- Dulux Wall Primer (white) painted directly onto a smooth wall with a short nap roller, rolling from top to bottom, making sure I went over this again with the roller (overlapping as I went) to eliminate any streaks and left to dry for 12 hours.
- Using a digital scales I measured out 960ml of Dulux Steel Grey 2 Vinyl Matte & 240ml AAA-F paint (new batch purchased from Amazon) and mixed this with a paint paddle and an electric drill for about 5 minutes or until there was no streaks in the paint mix. I decided from reading this forum that Steel Grey 2 would be the best for my particular projector

- Using a second short nap roller I applied one coat of this Black Widow Ultra mix, again rolling from top to bottom and going back over the painted screen whilst wet, overlapping as I went to make sure there was no streaks or patches

- I left this to dry for about 5 hours as the paint would give the impression of being too dark whilst wet and look streaky as it was drying with the projector on

- Turned on my projector, put on Guardians of the Galaxy Blu Ray and was very impressed with the results. The blacks are very black and the whites are also spot on. I will post the calibrations for my projector as soon as I get a chance and this has made a big difference to the picture quality. Before painting BWU I was using Dulux Light & Space Pure White, this gave me a very bright picture but with reduced depth because the blacks were not defined.

I'm no expert when it comes to home cinema so don't ask me about levels, I just know that I'm very pleased with the results.

All the best with you project.
