If I absorbed knowledge correctly the mirrors are only suggested with S-I-L-V-E-R as it is a translucent mix. Silver Fire is an opaque mix and does not really rely on the underlaying material for reflectiveness the way S-I-L-V-E-R does. So my answer would be to save the money and get the Sintra instead. I'll also say that my mind will immediately change if one of the people that have done both comes in and contradicts me as I can admit when I am wrong. (Usually...)

Uhhh.........guess again! How immediate is "immediately"?

S-I-L-V-E-R requires a "Bright White "Flat" Base, either Kilz-2 or in several recent cases, it has been painted directly onto Thrifty White and Sintra.

Light Fusion (w/mirror) is the one that really depends upon laying down several very thin, translucent coats that are just opaque enough to initially reflect back the projected light, yet absorbant enough to allow a degree of the received light to penetrate and reflect off the underlying Mirror. Light energy is lost during the absorbing, as well as the reflection, so when the light does return to re-fuse with the inital image, it's shifted down to a lower intensity (attenuated) and helps create a depth and contrast enhancement that creates a almost 3D effect. That's something extra no "Flat on a Surface" paint can do.

The advent of Silver Fire does make much of that redundant if the shade of SF chosen is at/under 3.0, and is applied over a bright White substrate. However, when I need a SF Screen of 4.0-to-6.0 and I can get an appropriately sized Mirror, I do so with impunity because the reclaimed light helps maintain both gain as well as strengthens the quality of the Whites/Colors as they reflect off the much darker surface.

Previously posted elsewhere:

Too small, with so-so ambient light performance.

No supporting information (actual screen size -PJ & throw distance) Build. Cost.

Very important criteria for and aspiring DIY screen that want to compare with a BD II or DNP

  • Size: 92" diagonal absolute minimum, the bigger the better
  • Materials: Affordable, easy to work with (comparatively speaking) Readily available
  • Impressive performance using normally available PJs at governable throw distances
  • Documented Build examples presented to share with DIY community
Supply and meet those criteria and DIY'ers will sit up and take notice.

Actually painting a pull down or electric screen?

I have a Favi electric screen and would like to have something better. Is it possible (has anyone tried it) to actually paint the Silver Fire mixture directly on a projector screen? Is it flexible so that it could be rolled up into the housing and rolled back down without damage?

I really prefer the electric screen since it is up and out of the way when not in use, but I am unhappy with the dull, washed out image I get with the current screen material.

Sorry....not even remotely in the running. between a lack of size, ambient light performance, and component availability in the US, as well as any degree of explanation of build criteria....it's just not to be considered.

And I'm certain you could never apply that mixture to a Retractable screen.
