Gentlemen,I am an audio nut, but not very smart about home theater stuff. I would really appreciate some advice in this matter.
I spoke with a fine old carpenter today that specializes in plaster work. He will transform the controured block wall in my basement into a nice even wall. The brick will disspear behind the plaster. This wall will be used for a front projection camera. The wall's plaster finish texture can either be sand or flat. The sand texture is similar to 80 grit sandpaper. The flat texture is similar to sheetrock. Which texture is perferrable for a projection surface.
I found several insights online regarding paint. It seems the Sherwin Williams ProMar 400 is a decent econo paint, and goo seems to be the high-zoot paint of choice.
Any insight you might offer regarding the wall's finish texture would be very helpful.
Thanks,

Dave,Goo Systems Digital Grey is great stuff but it's a pain in the ass to apply.
I did one wall screen by rolling it and I wasn't 100% satisfied with the final finish. Even the best roller will leave a textured finish.
I also made a screen out of 3/4" MDF (primed and sanded 3X) and while it was slightly better, the roller is the main problem.
At distances greater than 15', you really can't see the textured finish but something about the image bothered me.
I had a friend who paints furniture and cars redo a 84" 16:9 screen on the wall with a spray gun (plaster wall with flat finish) and the results were dramatically better. If you are not good with a spray gun, let a pro do it.
Another thing about the Goo Systems is that it takes time to cure. The initial results are very good, but I found that the picture quality got better over a 4-5 week period.
