I'm at my third DIY screen, in 6 years...
first was a 110 diagonal on gyproc with metalic sivler paint covered in berh white with a roller.. reslults pretty good actually, but my standards have gone up since.
5 years ago, i had a controlled light environnement with 120 diag screen and Mitsubishi HC1500 720P and the paint was simply a perle Behr with smooth roller agian on gyproc.. but really, that was pretty good.. i thought i would up it and read the projector central DIY post on a 100$... Painting the Perfect Screen for $100...that recommend ProClassic Smooth Enamel Satin Finish from Sherwin Willians.
I did it , the one stop shop.. contrast, color and whites are all spot on.. but i can see hot spots on roller marks... so i'm thinking another coat to improve smootheness (because second coat was better the first) or do i go with whole new receipy. I can paint, even with a gun if really nessessary, but roller is easier, ..
i have read through the posts, and there is just too much info , i can't get the information I need.
I am runnig a PT-AE 8000 in very ligth controlled room (little or none) utra matte dak paint and directionnal lights.. i have 125 inch diagonal screen that is 14 feet from the projector. I want a more precise image and no hot flashes and roller marks..
