How to cover black and maroon painted walls?

I'm living in a rented house, and the chick I rented from said it's OK to paint the walls... they were an awful sage-colored gloss, and I painted them to a maroon (3 walls) and black (1 wall) with semi-gloss paint. It's worth noting that I had some problems getting paint to "stick" over the gloss, in case that will affect later paint jobs.



Now she springs on me that I MUST have the room back to white before I leave... any tips on covering these colors? It's a small room and I will really only have a day or two to do the paint job, so I hope to find something that can cover in only a couple coats. Is there some sort of primer that can achieve this? What about this "Kilz" paint I hear about?

Use Kilz or Zinsser primer. Then the finish color. I know Walmart sells Kilz Original for $12 a gallon.
Reply:use a good primer, then a one coat paint
Reply:Kilz paint or at Wal-Mart they have a paint that covers odors and stains etc.. They will probably cost you around $15 a gallon
