Is it night and day, or incremental? I guess I'm asking if its worth doing.
Absewlootlee there is a difference. Even using a simpler advanced Mix like RS-MaxxMudd will improve the perception of Blacks, provide deeper and more enriched colors, and basically make the 8350's already great 110" images look like they come from a 65" LED TV.
Any paint choices jump out based on my specs?
1st choice: Silver Fire v2.5 2.0
2nd choice: RS-MaxxMudd (standard)
3rd choice: A Neutral Gray Interior Flat Enamel of 8.5 Munsell
(...the latter being acceptable, but sorta a "Kissin' yur Sis" choice...)
I should add that I have facilities and professional spray guns/manpower at my disposal.
That's great. The more advanced Mixes are by nature very thin, and go on much like a Clear Coat or Varnish. There are some differences though, so one you get to that point, be sure to review paint technique and ask any pertinent Q's .
Does 120" x 60" sound doable for the space and pj type? Any general advice for a novice screen builder with the above specs would be greatly appreciated.
Have the sheet cut to 106" long to achieve a 122" diagonal 16:9 image
If this is to be semi-permanent, then gluing the Sintra to the wall using a Elastomeric (water based) Adhesive (Power Grab works well) is the best way to get'ter dun. Miter-Cornered Velvet wrapped Trim is then butted up to the outside edges.
Another method that does not require much gluing is this: Have the Sintra cut to 60" x 104" (114" diagonal) and install the Sintra by applying some adhesive directly in the middle 1/3rd of the sheet, and then screw the perimeter down using coarse threaded Drywall screws. (1-5/8") You don't need to hit a Stud with every screw....just a few, but only hand tighten any screws that do not sink into wood.
Trim is then over layered 2" into the Sintra all around to give you the 100" x 56" central area.
One more note: I initially wanted to just paint the wall directly and bypass the screen option altogether, but was worried about the lack of perfect smoothness due to basic wall texture. I didn't want to sand it down. Is the process of prepping a wall like mine arduous? The Sintra screen is only $125.
Arduous? Not at all, especially if you have any familiarity using Drywall compond and Mud Blades. If the Texture is just very slight due to paint induced variations, them just a like skimming of Mud within a marked of / taped off area, followed by a light and even sanding and "sprayed" priming will result in every bit as good a surface as anything can be short of ultra smooth Plastic or Glass.
Use a 12" Blade. Apply the Mud in a sweeping motion...get the surface covered lightly, then once...only once, lightly scrape the wall holding the Blade at 45 degrees. That should fill in any depressions left after you have at first lightly sanded off the top peaks before you started skimming.
Use a 8" x 3" x 1" Medium / Fine Combo Sanding Sponge for the sanding chore. Medium to knock down the initial bumps of texture....Fine to smooth the Skim coating. All sanding is done using light, not aggressive strokes, and is done in long sweeping arcs.
I personally use a wall whenever I can....it give a greater degree of satisfaction to see a surface like that transform into a High Definition Screen.
