Paint Question (HELP!!)

[George Moehlenhoff]

So we bought a house, and removed the popcorn ceilings our self. We used a mixture of downy/water (50/50) and did not bother to cover the walls as we figured we'd be painting them; no big deal.

So we get the ceiling done, quickly sponge the walls in 1 room, and begin primer (Glidden PVA Drywall Primer/Sealer)spraying with our new Graco X5 sprayer.... The room drys, but we have a problem. Anywhere the downy water mixture dripped on the wall, you can see it through the primer; almost as if the primer did not take.

We are total rookies, and really worried we screwed this up BIG TIME!!!!

So pros, how do we fix our mess up? Thank you in advance for your help!
