We've got mold or mildew growing on the walls of our bathroom. We have washed it a number of times with bleach water, but it comes back. We installed a window fan, but it comes back.

What paint should we use to repaint the bathroom?

The paint that is on the walls now was applied over residual wallpaper glue left behind after a shoddy wallpaper removal job. It is pretty ugly and getting uglier -- the glue marks are darker than the rest of the yellow walls.

Should we try to remove the existing paint and glue? How? Or should we just wash and sand a bit and paint over it with good mold-resistant paint?

 

Sand the walls down with 80 grit paper. Use a sanding pole if possible. You don't have to sand them all down to bare wall, just try to knock off the residual adhesive, and generally smooth it all out. Wipe off all the dust with a tack cloth or damp rag. Prime it with an oil or alkyd primer to lock in the adhesive. Lightly sand again, and top coat with a Kitchen & Bath paint. These are available from Ben Moore, and Sherwin Williams, others may carry them also. They come pre-mixed with a mold/mildew inhibitor. 2 coats for durability recommended.

BTW, if you wash off the mold, and it keeps coming back, you have a moisture problem.
