It can, but under the same dictates as it would painting a screen. At least 3 Coats at maximum patter height obtainable and 60-70% overlap. It takes about 5 minutes to empty a Quart Cup on the Gun, and previous experience has shown it take almost 5 minutes to spray a coat onto a 16'x 9' screen.
If any wall is bigger than that....get a Power Painter!
But the Graco, with two needles to choose from, can do detail, trim, cabinets, water based stains. No Power Painter can.
Any specific primer on the vinyl?
Glidden Gripper Primer in "White". Thin just enough to get a solid 10" pattern using the stock needle. Observe a 60-70 Row over lap regimen. Apply 2 coats w / 2.0 mm needle. Lightly sand screen surface with Fine Grit sponge. Dust off, then apply a final Primer coat using the 1.5 mm Needle.
Use the 1.5 mm needle for all the "Finish Coat" Dusters. If any further sanding is done, it happens between the 3rd and 4th Dusters. 5 Dusters should be the target number. 6 maximum.
Lastly, given my projector and room (light controlled), what paint do you recommend?
Firstly, a 104" diagonal image requires a throw of as little as 11' 8" up to 12' 9". Wow...that's a whole 1 foot of play. So...I hope by saying "Just shy of 13' " you mean 12' 6" because you really need some degree of focal zoom remaining for unexpected formatting issues. It is never wise to try to run the Lens / Throw equation at each extreme end of the table.
