My bathroom is painted with an oil based gloss enamel. I would like to switch to a latex base. Can I use one of the new primer/paint combos?
Your best bet is to pick up a can of primer to prime your walls first, Killz2 or Zinsser 123 primer can be used. Since you are repainting your bathroom these primers are ideal because they protect against light water stains. After you put a coat of the primer on then you can paint your walls with your desired color paint. If the original paint color is dark you may need to apply two coats of primer and paint.
