Eggshell over satin
I am in the middle of painting the kitchen and nook with BM Aura. I tore down wallpaper, put Gardz over everything, patched and skim coated the walls, primed and now I'm painting. I got satin sheen because it's the kitchen but, even after the skim coat, there's lots of defects that are accentuated by the satin finish. I've got most of the walls cut in and about half of the walls painted. Now I'm wondering if it would be worth it to change to eggshell. Can I do that midstream? It looks like there are some places that I'd need to do a second coat (or at least patch anyway) but I'm worried about that turning into 3 coats because of the difference in sheen.
Would eggshell make a significant difference in appearance? If so, should I go ahead and finish up full coat with the stain and then do eggshell for the second coat or can I switch over mid job and save myself some work?
