For your existing blackout screen, about 3 coats of Behr "Ultra Btright White" in latex eggshell finish would be my reccomendation. This has about 1.3 gain (the estimate is from other messages in the Forum). The slight sheen of the eggshell gives you noticeably brighter reflections which drop off as you get pretty far off-axis. The next shinier finish is semi-gloss which some have reported hot-spotting with.
Behr paints are distributed by Home Depot. If your screen has the vinyl side out just paint that. If the fabric side is exposed, one coat of latex enamel undercoater should be used before the 3 coats of latex enamel. Painter's pads generally are preferred over brushes or rollers - lay the screen flat and alternate direction on the strokes between coats, each 90 degrees different from the last.
Greater gains than 1.3 require precision application of refective pigments and fused plastic coatings - best buy commercial screen materials for the higher gains, as yet no one has produced a satisfactory DIY hi-gain finish.
