It just looks like basic tails to me. Pressure too low (still), perhaps. Maybe you need to thin it out a little. Dirty or worn tip. And no backroll.

(I also don't like Emerald because the open time, in my experience, is less than many other paints. It easily flashes).

Dial up the pressure. Check you spray pattern before starting and look carefully at the fan. And get an assistant to backroll right behind you.

I was debating on backrolling and decided not to but I am second guessing my decision. I did a test spray on some cardboard before hand and it looked great no tails and even coverage. Tip has less then 3 gallons on it and has been cleaned well after first use bought the tip specifically for this job.

I was thinking maybe extend my spray distance? I could increase the pressure again but don't know if that would help.

I didn't even think about thinning it but wouldn't be opposed to it if it helped.

Thinning a bit and increasing pressure are more or less two different routes to the same goal of more even atomization across the whole fan. But the backroll pretty much "erases" whatever unevenness is left.

Now would be a good time to go here and tell up some things about yourself and the breadth/depth/length of your experience in the painting industry:

Is this new drywall? Are you Sanding between coats atleast?. I still don't get why people don't backroll. To me it's cutting corners.

This is now drifting off the OP's direct question and all. But Graco reps were at my local SW store once demo'ing their "Jetroller" system. I was pretty intrigued, but the co. wasn't ready to drop the dough.

I'm surprised I've not seen mention of them here (which doesn't mean there aren't any!), and wondering if anyone has one, had tried one, etc. I'm posting a link to an 18" (below), but they also have 9's. Maybe 14's - haven't really looked.
