Bathrooms and other humid areas can begin to grow mold on the walls and ceilings. This is a guide about removing mold from painted walls.
This is a video about removing mold from painted walls. According to the CDC mold spores can come into your house from the outside through open doorways, open windows or heating and cooling systems with outdoor intakes. Spores can also attach themselves to your clothing or your pets and be brought inside your house. Once inside, mold thrives and grows in moisture rich places, making the bathroom a common place to find mold.
Why is it important to remove mold? Not only does It look gross but inhaling mold spores can cause respiratory problems, especially for people with asthma.
Properly ventilating your bathroom when you are taking a bath or shower can help prevent mold.
Keep humidity levels your house to between 40% and 60% by using an air conditioner or dehumidifier during humid months.
For the removal of the mold we have chosen to use two products that you can buy at your local home improvement store. Mold Armor Mold Blocker and Mold Armor Mildew and Mold Remover.
You need to be careful with these products. A mask, eye protection, rubber gloves and a ladder are recommended. Avoid leaving Mold Armor Mildew and Mold Remover on vinyl windows or plastic shower enclosures for more than 15 minutes.
The video shows the mold on the ceiling portions has completely disappeared. On the top of the window, where the mold was the thickest, a second application was needed. After that, all the mold has disappeared.
While these products were successful, the drawback is the expense, these two bottles cost about $15.00 combined and we only need amall mount of each to remove the mold.
It will require a little more elbow grease than using the store bought removers, but it will work.

Here are questions related to Removing Mold from Painted Walls.
Black mold is growing on the painted walls of the hallway near ceiling. This hall has a furnace and is near a bathroom. It's been about 2 years since the house has been lived in. I noticed a very musty smell when we bought the house to resell. I assumed it was from being closed up and vacant. We have tried cleaning it with bleach with little results of removing it and now the walls are discolored. What will take mold off? Will paint cover and stick? Could the furnace be the source?

I had my bedroom wall treated for damp and mould a few months back and it seemed to cure the problem. However I've recently decorated with emultion paint, but noticed the paint won't stay on in the areas that were treated. I'm not sure what was used to treat the mould/damp, but wondered what I can do to cover the walls now?

I think you should contact the company that did the treatment and find out what they used, and if they know how to deal with the problem. If they are not helpful, contact a paint company, armed with the info you have gotten from the mold treatment people, and find out what product they might have or what you might have to do to prep the walls for paint. It may be as simple as using a good primer. Here in North America, we have a paint called Kiltz (I think that is how it is spelled) that is useful for these sorts of things. I think you are somewhere else, however, as we do not talk of emulsion paint.
Our home was built back in the mid 50s and we seem to get mold only on the exterior corners at the ceiling and top of the walls as well as in the corners if furniture is up against it. We use Concrobium mold control to clean the surfaces as well as to treat it. This issue has also caused the paint to come off of the walls. We are not sure if an oil-based paint was ever used, and we did paint them with a latex paint. Any suggestions on how to eliminate the issues?
Our basement got flooded a few weeks ago. Now we have mold and mildew on our walls. The walls are textured so they're rough. How can we clean them?
How do you get mold off painted walls?

I've used a mixture of one part laundry chlorine bleach to four parts water. I dab it on with a sponge, leave it for a few minutes, then rinse it off with a rag and let it dry thoroughly. If necessary I use a hair drier. Obviously I put newspapers on the floor in case the bleach drips.
I am looking for appropriate information on removing mold above my shower on the painted ceiling. The wrong paint was used at the time.

Fill your bathtub with steaming hot water and add to the hot water a handful or two of loose olives leaves. Buy loose olive leaves by the pound. (herbalcom.com is one source and very reasonably price.) Keep the bathroom door shut for about an hour to keep steam inside. Wait and watch the mold breakdown. Then wipe down with a saturated sponge of the olive leaf water solution, and your problem will disappear! Repeat if the problem recurs, which won't happen often, if at all.

You can use this product to reomve mould and any odour associated with it. http://www.furnitureclinic.co.uk/Mould_Neutraliser.htm
More importantly though, it kills all bacteria and so prevents the mould re occuring

How do you get rid of mold on painted walls? I scrub it off but a black stain is left. How can you get rid of this? Also, the mold is back within the week any ideas on how to stop it?

In cooler damp climates like Britain the atmosphere is often laden with moisture and this can be compounded by the moisture produced within the house from the kitchen, bathroom and given off from the breath and skin of human bodies. The answer here is to increase ventilation, whether through opening windows and doors, especially after bathing or showering, or have an extractor fan installed. Raising the internal temperature of bathrooms while showering to heat the walls slightly will also prevent the moisture suspended in the air from condensing out when it hits the cooler surface of the wall. But you must then ventilate to remove it from the house.
A bleach solution, (as directed on the bottle), should remove the mould, kill the spores and whiten/lighten the stain. It will recur unless you sort out the ventilation problem, even if you paint over the stain, although some paints have a built in fungicide to discourage mould growth. Regards. Jo (01/24/2005)

This may sound like quite a hassle and to tell the truth it was, but, believe me, I couldn't even use that room except in the summer due to the heavy amount of mold and it's nasty smell. Now, that I've sealed the walls I can use that room and I just love it.
Important: My mold wasn't the toxic mold you hear about on TV. Yours may be. Use care around any household mold and keep your kids away from it too. If you have any questions, call your local Health Department.
My "sun-porch" turned "craft room" is totally made of plywood, the wood held up to all the bleaching. Wallboard may act differently. (06/15/2007)
