Xlent screen shot too. Mind sharing your camera and technique?
Thanks, but I really didn't actually do much at all. I just sprayed the stuff on the wall! The mixture did all the work for me.
My camera is just a cheapo 5 MP Panasonic DMC-TZ1. Nothing special. I think I had everything on "Auto" mode... no flash. Maybe the first picture was with ISO 80 or 100, I can't remember.
Anyways, I started with just the bare drywall. The drywall guy put a skim coat of mud on it to help smooth everything out and to keep the surface texture uniform. Also, once I put primer on the wall, it would be more uniform in terms of the primer "soaking into" the wall.
Then, I put on 5 coats (I think) of Glidden PVA-type primer. It was very thin, but it looks like it covered pretty evenly. I sanded between coats with 180 grit paper. It was VERY smooth. Finally, I used a Wagner Control Spray gun (looks like an older model) to apply the mixture. Here's the mixture I used:
1 quart (32 oz.) of Behr Faux Glaze (at Home Depot)
2 oz. of Delta silver (at Michael's craft store)
8-10 oz. distilled water (I actually used about 16-20 oz. of water)
I had to use more water than the original recipe called for, because it was too thick to go through the viscosity-measuring cup that came with the spray gun. I sprayed my coats at about 30-45 minute intervals, with about 9 or 10 coats total.
Here's the spray gun I used:
And here's a closeup shot of the wall after spraying. You can see the amount of overspray on the surrounding black border, although you can see small specks of silver extending all the way out to the SIDE walls, which are about 2 feet away. That stuff really travels far!
Anyways, that's it. Nothing special, and I would use this method for a screen again in a heartbeat. There's no way I would pay $500+ for a "regular" screen unless I had no other choice. This spray technique right on the wall (or a suitable white substrate like a whiteboard) is definitely the way to go. When I had the projector mounted, I previewed "The Matrix", which is extremely dark in some scenes, and it looked amazing. The level of detail in the blacks and dark greys was absolutely perfect. In the opening scene where Trinity was sitting in the dark room on the computer, you could see every detail in the shadows.
Anyways, I only applied the stuff to the wall. I didn't invent it. I owe all my results to the originator of the mixture and to the recommended spray technique. It worked beautifully. Anyone who might be afraid that a DIY screen with a painted mixture would suffer with detail and dark blacks or bright whites, shouldn't be. I've never seen such a clear picture with rich colors in my life.
I hope this helps encourage others to use this method. It's well worth the $15 in materials cost.
