This idea of a DIY screen sounds interesting. I would like to try the quick and cheap option of turning an area of a wall into a screen. The wall is drywall that is painted with an off-white (the paint probably contains small amounts of yellow and red) with a satin finish.

I would use a flat, ultrapure white paint as suggested in this forum for other DIY screens.

1. Do I need to sand the surface smooth?

2. How many coats of paint should be necessary?

3. I am not expecting to need to use a primer. Is this a valid assumption?

4. What type of roller would be best?

5. There will be a lot of ambient light at times. What can I do to minimize the effects of the light?

Thanks

Dave

Dave,
I did just what are talking about this past week. My wall was a kind of tan color. I filled a couple of imperfections with drywall compound and sanded the whole area very lightly. I used 3 coats of Flat Behr Ultra Pure White paint. I have heard of others using eggshell which is one step up in sheen from flat. This gives the screen some gain. I can get my room completey dark so I went with the flat. I used a Purdy 1/4" nap roller and this left a very smooth finish. Just take your time and roll slowly and thoroughly smooth out all the paint. It came out great.

Good Luck!

Paul

Dave,

I agree completely with Paul.

You can also use floetrol to help keep things smooth. I also do recommend the eggshell but I didn't have very good results with the satin level. Things started to hotspot.

Also texturing on your walls (if applicable) will screw things up. Sand it smooth.

Ps. Stewart recomended homemade screens himself for unity gain on the Big Picture's VW10HT forum.
