I sanded the room with 100 grit, it was a PITA but it really helped. I need to follow up with 180 grit before then I'm ready to prime. I did have a nice suction going with a sealed off box fan in the window, sealed doorways and AC vent.

Hindsight is 20/20 but I probably should have laid plastic on the entire room and knocked out the popcorn ceiling at the same time.
