Thanks for this great thread. I sprayed out my screen about a week ago. I tried following the directions as close as possible. Spraying is definitely the way to go. Quick rundown on materials/construction.
I used 5/8ths MDF (49' x 88') for the screen with french cleats on the rear. This made hanging the screen a snap.
I thinned the Kilz2 about 25% - sprayed about 4 coats and sanded between. I then sprayed the glaze - 1 quart of the faux glaze, 2 ounces of Delta silver and 25% distilled water. My experience with the glaze was that it went on very easily. I put on very light coats (almost dusting). I found that because of the light dusting, I was able to spray another coat on in about 20 to 25 minutes. I probably put on about 15 coats (I guess similar to what DevonS did). I used flat black to trim the edges of the MDF - makes the screen appear to be floating.
Results: I am very pleased. Really came out much better than I had imagined. I would agree that this has to be sprayed (not rolled). I don't know if I can really see the metalic in the paint - or maybe I didn't mix right. Although I put on 15+ coats - they may have been to thin - but I felt at the time if I sprayed any heavier it would start to run. I probably didn't wait long enought between coats - but I just couldn't wait any longer! I'm not for sure if I did everything right but for my first DIY screen - I coudn't be more pleased. I working on the masking (attached to the wall) and should have it up over the next few days. I'll take some pictures & try to post.
Special thanks to CMRA and MississippMan for all of the information and time spent posting.
