I recently tried to build my own projection screen and ran into a serious problem when trying to get a good ambient screen paint mix...aka Black Widow
. My screen is a 115", 16:9 ratio. I am using 3/4" MDF for this screen. What I am trying to achieve is a screen that works decent in ambient light. The room does have several windows but all of them have cordless blackout shades that I can pull down if need be. In other words the room can get pitch dark if needed. I really don't want to sit in the dark with my buddies to watch college football...makes the atmosphere a little weird. This is what I did....please tell me what I did wrong.
I gave the MDF sheet 3 coats of high quality primer and made sure it was roller mark free using a 1/4" nap roller. Then I went to Menards and gave them a picture of the paint number for Pittsburg paint Bermuda Beige that I wanted. I tried to attach the picture I gave them. The number on the can he gave me was 427-2 which I thought was correct with grand distinct flat as a base I believe. But the Red/Yellow/Brown Oxide numbers were different. Can they be different, the store said that was a quart of Bermuda Beige?

Then I ordered 2-4oz bottles of Auto-Aluminum from Amazon. They were labeled 4101-4Z Fine.
I mixed the quart of Bermuda Beige with the 2 bottles of Auto-Aluminum. Mixed it thoroughly with an electric drill and accessory. Now here is the main problem. The final paint color is not grey
. I wouldn't even consider it much different than from the quart of Bermuda Beige. Very little darkening if any at all.
I mixed 1 quart of Bermuda Beige with 8 fl oz of Auto-Aluminum Fine.
Please tell me what I did wrong. I can repaint if need be but its starting to get a little expensive.
Thank you for the help.
