extra extra extra wide fabric. 390" 16:9 screen

Awwwww....that's just "small change".

How about 28" x 48"?

I've been toying with a few ideas using the "smaller" 12' to 16' to 20' wide varieties.

......and the materials listed above are infinitely less expensive. Best of all....they are NOT Projection Screen material.
(...which is why they are not very expensively priced....)

I think he means it could used as a surface for a painted screen, like, MS-MUDD or Silver Fire.

Is that right MS-Man ? would it work with those paints ?

It does not appear so, and no mention is made of such. I haven't gone so far as to call them about it yet.


What part of "Toying with the idea of..." seems to indicate I've actually seen/used any of it?

Just messin' wit'cha.

But the material in question is made to Screen Print advertizing onto...it's the stuff that covers Billboard Frames. It's not glossy...as far as the description indicates, and that tends to indicate it's a Matte Vinyl coated material, as descibed.



Absolutely. And if one used it for a "Big Picture", big picture, say something like a 32' x 18' screen, I seriously doubt that any seam deemed acceptable for use on a surface that is viewed for advertizing messages would be too intrusive for use as a projection surface of such size, considering the distance one would sit/stand from such a surface.

No matter what, the available size vs. cost factor would/does outweigh many lessor concerns. And even if the surface is too glossy "raw", with the application of a "Gripper" primer" and any applicable paint, the end result would be worthy of being a screen surface that would cost many hundreds of not indeed thousands less than anything else one might...or could consider.

I agree. I was a little tickled when I "sorta" chanced upon it....but real credit goes to another astute member who PM'd me and pointed me in the right direction.

The various selection of sizes available is very wide, and the prices ARE ALMOST SILLY INEXPENSIVE !!!!

All in all, it portends to be a great source for DIY HT & Outside Theater advocates to acquire suitable (...and affordable...) over sized material for screens.

Hey MississippiMan,
If the white tarp is glossy,could it be used as is, with CMRA's S-I-L-V-E-R Mix,but with your "Delta"mix (bellow) for a High Gain screen ?
Not like using a mirror but would it still boost gain ? If it could work, would it be like(White Fuson) ?

MississippiMan's, (Delta) S-I-L-V-E-R
1/2 gallon Behr Faux Glaze
4 oz. Delta Ceramcoat Silver Metallic from Michael's Arts & Crafts
(Substituted for the darker Behr Silver Metallic)
20 oz. Filtered Water

Unfortunately, The Delta Silver metallic has been discontinued. Even my once ample supply has been exhausted. (Believe it or not...I do still have 32 oz of the old Behr SM.)

Instead, the substitution is Liquitex Silver Metallic (Silver) at "6 oz." added.

And yep...if you apply the S-I-L-V-E-R in the proper manner....7-8 Duster coats, the "semi-Gloss" Vinyl will do nicely.

What concerns me more is the inherent underlying weave texture most Tarps have.

S-I-L-V-E-R tends to enhance surface texture & defects, and if your viewing too closely....for many the resulting visible texture can be more distracting, and therein a greater hindrance than the uncreased Gain and contrast is of benefit.

MississippiMan,
Would BOC Cloth painted with a gloss or semi-gloss white base coat and 7-8 duster coats of S-I-L-V-E-R, make for a pretty high gain screen ? Would using a gloss white base insted of semi-gloss, just be asking for hotspots ?

Is there a winner or King of the Hill champ, in the DIY screen paint world, for Highest Gain screen paint ? One that does not use a hard to find (In large sizes) reflective under base like a mirror.

TBP,

S-I-L-V-E-R works best with a "Flat" bright white surface. It already has significant gain, and increasing such by increasing the amount of light reflected back from under the painted surface can be counter-productive.

The biggest issue to face is coating BOC with enough Primer, and sanding the 2nd/3td coats smooth enough to avoid any trace of texture...something that S-I-L-V-E-R would enhance.

Thanks MississippiMan, for the 101 class, in the proper use of S-I-L-V-E-R.

Pop Quiz next Friday.

Pass or fail.

Is that to say every 8' laterally, as in across the horizontal? Does the surface to be shot upon feel smooth, as in having no bump at the transition point between seams?

What needs to be determined is as to iff the Seam presents a raised edge on the "business' side. If not, then painting over it ( or simply projecting over it ) should present no issues.
If it is "raised" at all, most likely Projecting onto it "as is' won't create any issues...but painting a High Contrast coating might make a line be quite visible when the surface is under normal lighting.

Often though, illuminated by a bright PJ beam, it's not visible.

Really, it's the presence of a long raided edged seam that is mostly my concern.

Bleah......,

Might not be an issue as seen/viewed from a Highway, or anything from 25' away or more.

What was really hoped for is that normal sized 16' x 9' screen surfaces would be presentable as seen from ....say 16'

That would seem problematical at best here.
What I've gotta wonder about is as to if the 10' x 36' or the 12' x 30' sizes have that seam at 8'?

I'd like to hope that it's your big 'ol 16' wide size that has a seam at 8'......only.

When all hope is lost....dream on...............

OK....now that reads to me that in sizes up to but not beyond 12' "Wide" there is no seam.

So........the size sheet that is 12' x 30' would "NOT" have a seam............?

Gosh....just trying to get a precise and definitive answer here.

Upon my contact, I was told that "any" size above 10' wide that is "new" material would have a seam in the middle, side-to-side. However, the used material....usually coming as Black on one side (...the side originally printed upon...) , and White on another side (rear), can be had in the 10' x 36' size without a seam. Of course, since it is the Black Side that is the surface we would want to use, it would require Priming / Painting.

But the dreaded "Seam' would not be an issue, and what's really good is that the top / Bottom Edges are folded and a Channel for a Rod or such is provided. That reinforced area would also be good for introducing Grommets.

Soooo.............., while the stuff might not be good (...or as good as hoped...) for using on a bigger Screen, even with a seam at 8', that would still allow one to manage getting a 92" x 164" (188" diag) surface without a seam.
