About 8 yrs. ago we bought a home that has sheetrock walls and ceiling in the bathroom that are textured and painted. I have repainted the walls 2 times with bathroom paint and in the last couple of years we have been battling mildew spots on the walls and ceilings. I have cleaned them many times with products like Tilex but they always return and are getting worse. Any other suggestions or will I have to completely redo the bathroom to get rid of the problem?:confused:

Bathrooms are particularly susceptible due to the moisture. The standard recommendation is to run your exhaust fan for an additional 20 to 30 minutes after showers. In other words get rid of the excess moisture. A humidity level above 50% is what mold needs to grow. To make this process easier, they have a special switch with an adjustable delay when you switch it off.

Good Luck

If you use this bathroom do you use the fan! The fan should stay on for twenty minutes after bathing to remove the RH.

Ditto on the exhaust fan.

What bathroom paint did you use? Zinsser's Perma White is guaranteed to be mildew free for five years.

I would expect you could go longer (than 5 years) with a good ventilation procedure in place.

You may want to consider just using a vinyl tile for the bathroom. Because they are moisture resistant, you would not have to worry about any molding or anything like that. I've used the tiles from NoAds.com in my own personal Bathroom and they have worked out great. you can get direct mount or if you're planning on installing a grid they have tiles for that too. Either way it will take care of any molding or staining problems for good. Good luck!

Not sure about Tilex, but Clorox is what I use to wash mildew, 50%-50% mix with water and then rinse. Even the least bit left and painted over will lead to it's return.
