How long do I need to wait before priming/painting over hydraulic cement patches? I have a can of Quikrete Water-Stop. However, there are no instructions about painting. I have searched the Quikrete Web site, but could not find an answer.

I had ceiling border on my ceiling (I didn't do it!) and they were dingy, I needed to paint them. I removed the border, did some patches near the cabinates (the border was covering up flaws) and sealed the whole shabang with zinsser gaurdz. I then primed with zinsser cover stain. I figured with all that only one coat of benjamine moore ceiling paint would be needed. It seemed to look OK after it dryed but now I can see some streaks. It was hard to paint with a roller with 3/8 inch nap, the ceilings are only slightly textured but I guess that's still too much. I thought I managed to cover everything though but they don't look bright anymore. So what gives. I don't know if it's an illusion because I've painted the walls so the ceilings that looked bright now look less than spanking white or maybe the coverage wasn't as good as I thought because of the roller I used. I noticed when I did the hall I couldn't tell how well I was painting unless I used a spotlight on the floor. It really seems to have changed the last few days which bothers me because I asphixiated myself using the smelly cover stain when maybe I would have done just as well to use latex based kilz or something. I don't have wallpaper border in the other rooms I am going to do, would I be better off to use kilz in those ones? I did a utility room that had bad water stains with kilz a few years ago and it still looks great even though I didn't topcoat with a ceiling paint! I'm bummed because it's like I have this aching neck for nothing.:wall:
