Hi I’m looking for advice:

I doing some work at a friend’s small bar-restaurant.

They have a (vintage I believe) Sharp brand manual pull down retractable projector screen (about 6’ wide) mounted at the tall ceiling.

I believe the screen is a “glass beaded” white screen. Because it has a texture And it snags a micro cloth if one tries to touch with it.

The restaurant is a greasy place and the screen has some stain rubbed spots which are missing what I believe is glass beading which affects its viewing, yet it’s still white screen paint-color even there.

I found most of the online cleaning info does not apply to these glass beaded screens I read are fragile and difficult to clean and some of these screen makers say not to even allow smoking in the same room.

I cleaned the screen with compressed air. This did not remove all the dust and dirt.
So I hung the screen outside on a fence and sprayed it with a diluted dawn dish soap and then sprayed off with a light garden hose weak multi sprayer. Then blew dryer with an air compressor and let air dry after.

The projector is a modern HT1075 benQ brand, at the end of a ceiling mounted tube(about 4’ long).
I’d guess the projector is about 10’ from the screen.

The screen cleaned ok but does have some damage spots.

In reading about these glass beaded screens I found they were for old dim bulb projectors.
They are not desirable with our modern high power lamps.
Because the glass beads the light reflects back to the projector(where the light came from) and creates a narrow viewing angle and poor definition, etc.

In further reading I learned that a silver/gray flat/satin screen might be best for use in this bar-restaurant because it is used at night in a lower mood lighting room atmosphere.

Some Q’s I wanted to ask here:

Is my research above correct or?

Can the damaged spots on the screen be easily repaired?

Can the screen be repainted into something better/more appropriate? I.e. perhaps wire brush the glass beads off and then spray paint over with a silver/gray?

Or perhaps is there an affordable replacement screen which I can slip into the retracting tube and bottom pull down weight pipe, to replace this screen?

Should I just leave the screen as is?

Thank you for your time

Leave the screen as is until you can buy a suitable replacement. Manual roll down screens are some of the cheapest things on the planet and I would look for one that's more in the 120" diagonal size range.

In a sports bar type setup, I probably would have looked for a WUXGA projector on eBay for under $500 total, and with 5,000 or so rated lumens to really make the image pop in a sports bar, then gone with a motorized grey screen of some sort.

The best is long throw ALR screens in such a space because it really makes the image pop, but those screens can be expensive and they are a bit more fragile.

So, if you can get a grey screen it would be the best option at this point for what you currently have setup. But, I would go to a larger size if the space allows for it.

Thank you for the reply!
Well with the current projector I know the size is turned all the way up on the lens. So to take advantage of a bigger screen, the projector would have to be moved back. Although you talk about, it seems a brighter projector than the current BenQ. So perhaps you also mean the benQ isn’t bright enough to be moved further away.


Well they don’t use the projector too much. A classic/unusual movie playing is a side show distraction oddity. It’s not a sports bar but a hipster like place.
I’m doing things on a budget, so if I can’t improve the existing screen any further, can’t improve/paint over the surface with a gray for a guaranteed improvement, then it’ll probably stay as their screen for the foreseeable future.

Ok I reread your reply. Sounds good. A new grey screen perhaps someday in the future, perhaps a projector.
