I'm building a 150" screen to be used in a fair bit of ambient light with a BenQ W6000 projector.
As far as I've been able to deduce from this long running thread the Silver Fire 2.0 (which as far as I can see corresponds to "Silver Fire - L (Lite)") would be the best choice.
- Is this true?
Yep. And Yep.
Throughout the thread the term "Duster coat" is used but never really explained thoroughly.
- Is it using the SF paint to create a thin layer before the actual painting? Somewhere it's explained as:
"And If you can, then I assure you that when shooting the wet SF from 12" to 14" and moving 2 ft per second, you WILL lay down a Duster Coat".
I think it has been explained about 100 times.
A "Duster" is accomplished by rapidly moving across the surface so as to lay down a sparse coating that will serve as a "Tack Base" for the heavier coats, so as to help prevent runs. It is applied as quoted above.
I'm ordering the ingredients from Europe, so I need the correct amount of paint in the first go (= not too little). I've never tried to spraypaint before.
- How much do I need to order for a 150" screen?
If you make up the SF mix as specified you'll have enough for your Screen
What's the best substrate (isn't that the material you're painting on?) for the Silver Fire mix?
Any very smooth, hard surface can do it well.
Somewhere I've read about a mirror? Erh, is that like a real hugmongous mirror that you paint on??
Yes, a 1/8" (3mm) Acrylic Plastic Mirror. That is the basis behind what is called "Light Fusion". I myself reserve it's use these days to applications that need the darker Silver Fire formulas (4.0+)
By the way, thanks for all the great info on this forum... it's really been an eye opener = now I don't have to spend a fortune on a screen when I can make one equally good or better myself. Also, It'll be sweet knowing it's a homebrew!
Well, hope you have time to help another newbie
And I hope I did.
