HP Opaque Scrim? Has anyone tried it?

post #1 of 8
Thread Starter 
I was wondering if anyone has tried this product or something similar in making a DIY screen. It is HP Opaque Scrim Outdoor Banner Material. http://h41186.www4.hp.com/country/us...pageseq=318031 I am in the printing business and use this product to make outdoor signs in full color. It is a great product in the printing world and was wondering if anyone has tried it and how well the colors are from the projector? I plan on making a 120" CIH using Epson 1080 Home. I can get this at a fraction of the price or even if we have a misprint I can use the back :-) of the bad print. Any feedback would be great.

It looks like it could work very well. It looks like the width is limited to 60 but that could work well for many people.

One of the drawbacks of this type of material for the average DIYer is availability. Someone in the printing industry could easily get a piece for a single screen but others may not want to invest in a full roll.

Please keep everyone posted as to your results and if it looks good maybe a group purchase could somehow be worked out.

Today I took a 2x3 foot sample of the HP material to my local HT guy. I was amazed at the quality of the material compared to the screen material he was using to demo an Epson 1080 Pro Cinema projector. Stupid me forgot to ask what type of screen he was using. You could not tell the difference in the colors but the blacks were a little better (with a picky eye) with his screen.

I am going to make a DIY Screen with this material. The only problem, is that this material is very very difficult to stretch. Looks like that I might have to adhere it to some type of backing. The stuff is pretty thick and would work great with spray adhesive onto some type of board.

This is what I have in mind... The screen size I am going for is CIH 110x47. I was thinking of putting some 1x1 furring strips up on the screen wall. Mount a 1/4 inch piece of drywall to the furring strips. Between the furring strips add some insulation. If I am going to have a gap, then stuff it with some pink stuff and could be a mini bass trap. I have no idea if that would work as a bass trap, but I'll give it a try anyway. After the drywall is hung, then I will have a smooth surface to work with. I will use adhesive to attach the screen material to the drywall. I plan on putting rope light around the screen hidden in the gap to give the screen a glow or floating look. The screen with also have velvet trim.

Any other Ideas would be great. If I decide to go that route, I will take pictures. LOL I am a long way off from getting a projector, so I won't have any screen shots, but only pictures of the build.

What is "Pretty thick" ? If it's at least 1/8" thick, I'd suggest you use a 'trowel-able' adhesive with a good working time (10 minutes at least) Liquid Nails for Paneling is a great one, and spreads out to a very thin coating that will not create "bumps or ridges" on anything short of something with the thickness and rigidity of Corrugated Cardboard.

Try it, but it won't really work to do much in that regard, because for a surface to "Trap Bass" it must be able to absorb, not deflect. Your surface will just be another flat, hard wall-like surface, although by having the insulation between the Furring Strips, that will prevent the screen from rattling with the effects of sound pressure levels.

But there is another thing to consider. How far apart to place those strips? I'd advise a gap no more than 8" if your using 1/4" Drywall. If you want a 110" long piece of 1/4" material to stretch across that length without any noticeable waves, you must set the end furring strips in place, then stretch a taunt string line across the distance at 1/4 down from the Top and Bottom, and when putting up each additional strip, adjust accordingly with shims or shaving. Make these strips exactly 1" bigger (longer, height wise) than your actual screen material. **

**You should consider that this is an assembly that cannot be "moved, and the 3/4" gap you'll have will not give you any working room to place rope Lighting afterwards. So you'll have to construct the Furring Strip frame as being like a Box Frame that is, and install the Rope Lighting into the type of "U" Channel strips you can glue/stick to the perimeter of the framework. Most places like Home Depot who sell Rope Lighting Kits also sell 6' sections of "U Channel" with "Sticky Back". I always place a few small screws through such to keep it in place.

After the drywall is hung, then I will have a smooth surface to work with. I will use adhesive to attach the screen material to the drywall.

I'd also use a strong adhesive with a quick bond to apply the Dry Wall to the Furring strips. Liquid Nails for Projects would be good. Take a 2" x 4" x 10' and screw it to the wall with it "lengthwise" across the distance. Place the screws no more than 2" out from the edge of the "Furring Box" (...almost 1" from the installed Rope Lighting...)so they will be covered by you 2-1/2' wide velvet trim.

Set a piece of Drywall in place, mark it's edge's location, add another Furring strip or a piece of Plywood Deadwood at any break point not supported (1" x 2" furring strips do no offer much "Footing" for two adjoining edges to meet together on. )
Attach the Dry Wall with the Liquid Nails for Projects by applying a 1/4" wide bead the length of every Fur Strip (...but only on the area of Fur Strips that lie under the area of Drywall your specifically hanging at that moment...)

Put down those beads, then take a disposable piece of something stiff with a smooth edge, or a 2" Putty Knife or Scraper, and smear the Liquid nails flat on each Fur Strip. Place the Dry Wall into place quickly(...of course you'll do the bottom pieces first, then stack the top pieces on them....cut the Dry Wall so it goes on in a "Brick Laying" staggered manner.) and press into place, then shoot Dry Wall screws into the Furring Strips at the outermost edges where they will still fall underneath the Trim to be applied later. This will, along with the adhesive on every available Furring Strip's surface area, will be just fine to keep everything in place while the Glue completely sets.

See above recommendations.

Well then, take your time and knock this out. If your using this material, keep in mind you can also give it a coating that will ramp up it's performance. You could Roll or Spray almost any of several paint applications that will be far better than even your local HT Guy's screen, so you might want to consider that as an option.

To help you understand my gibberish-like instructions, I whipped you up an illustration. I hope it helps you on your way.

WOW!!! I was not expecting to see this type of feed back!! Outstanding!! Thank you for your reply. You made a lot of great points. You are the man.

-I decided to go with 1/2 drywall - reason: I have two unused sheets
-will frame using 2x4's - reason - i have tons sitting around
- will use an one inch "L" shape trim piece to hold rope light will be flush with dry-wall



String outline for frame



Wood Frame



Drywall added

Note that the drywall did not cover the top part of the 2x4. No worries there. The trim will cover this up. I will be ordering the scrim next week and I will post pictures of the scrim then the trim work. Maybe rope lights too. i know some of you will say that the screen is off center. Yes this is true. I have two columns the sit 3/4 towards the back of the room. I one of the poles is almost dead center in the room. If i offset the screen, then I can fit a 86" couch
between the poles.

Well, I got the HP Scrim material up. It took several days of stretching. I would do it one day and there would be no waves. Then the next day I went to check on it, some waves appeared. I stretched it again and the waves were no longer there. Did this for a few days and now looks like everything is good. The next step is velvet trim and rope lights.

I hate to spit in your Post Toasties, but you do not want to wedge the Rope lighting into a space where it touches on both sides. Even though the lights are miniscule, under those conditions the strands can get quite overheated, leading to a greatly reduced lifespan, or in some cases, actually scorch a cloth material, or heat a painted surface to the point you can smell the "heat".

It just takes a very small space....but that spacing is essential in it's necessity.

Touching on two sides is not allowed.

Thanks for the feedback, you have been a great help. going above and beyond! What about LED? Below is the distance from the wall to the screen. It is roughly 3 inches from the wall. Once the trim is on there will be an overhang of 2 inches. Still would like to go with cheap rope light, but if I have to upgrade to LED because of heat I will. Still have to add Linacoustic to the wall. Give or take just over an inch.
