Appreciate all the detailed info in the posts from you and MississippiMan.
I am in a stuation very similar to what you addressed for BigSwifty in post #38 of this thread. (Optoma HD20...short throw).
My throw distance is actually limited even more than his due to duct work. (8') I am setting this up as basically a large screen TV replacement (72" diag at max zoom) and not so much as a dedicated theater.
Currenly the walls and ceiling are light and so I have reflection for sure, but overall I am pretty happy with it.
You recommended for the HD20 and short throw that ULTRA Exterior Flat #4850 tinted N8 without the addition of the Minwax poly should be sufficient.
My main question is whether adding at least a bit of the poly (say a 6 or 8 to 1 - paint to poly ratio) would help with the overall finish of this paint when rolled with your 2 roller method?
I have not ruled out going with a sprayer...but feel like I can certainly get good results with the roller method. Just wanted to make sure that at least a small poly addition will not make the rolled surface just that much better...or if having the extra sheen really makes it better to include none at all for this short throw config.
Edit: I purchased the N8 Behr w/4850 base, and some Minwax poly satin, but now after reading additional posts, am considering using a matte poly that I can get at a craft store. (http://www.joann.com/joann/catalog/p...RODID=prd32927
) Ceramcoat Interior waterbased Matte Poly
Would this be a better option for this config to thin the paint but not add the additional sheen of the satin?
