Really beginner question on paint.
I'm repainting a tiny powder room. It's current finish is matt, so I filled the nicks, sanded lightly and started to apply killz 2 latex primer as that's what they told me to get at the store. Problem is, it doesn't seem to be sticking very well. It's hard to see what I'm doing as I took the light fixture out until I paint at least that wall. Is the primer wrong, or did I not prep enough?
