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.

Prevention Tips:

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.

Removing Mold

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.

  1. Open your windows and turn on your bathroom fan so that you have good ventilation. Spray the Mold Armor Mildew and Mold Remover directly on the mold and let it sit for 30 minutes.

  2. After 30 minutes, using a wet sponge, wipe off the area. Most of the mold should be gone. If any remains, reapply the spray again and wipe it off with a sponge after 30 minutes.

  3. The last step was spraying the mold effected areas with Mold Armor Mold Blocker.

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.

Homemade Mold Remover:

  1. You can also make your own mold remover using bleach and water.

  2. Mix 1 cup of bleach with 1 gallon of water.

  3. Wearing rubber gloves, use a sponge or rag to use the bleach mixture to remove the mold from the wall.

It will require a little more elbow grease than using the store bought removers, but it will work.

I had a leak in my bathroom and it caused mold to grow on the wall and go through it all the way to my couch or the other side.

I tried various ways for removing it and failed (it keeps coming back) so I intend to buy a new couch and keep it away from the wall.

My question is, what would be a safe distance? Would 5 inches away from the wall ensure that the mold won't travel and hit my new couch as well?

I am much more concerned about the ongoing mold problem in your home and possible diseases it may cause in humans and pets. Mold forms and travels by means of sending out microscopic spores into the air. From your description, a water leak caused mold to grow inside a wall that eventually moved into your couch. A new couch will not solve the mold problem as the spores will continue to form, float in the air and out into your room and house. New mold infestations will grow anywhere there is moisture. A distance of five inches or five feet will make not any difference as the spores float in the air and land anywhere in the room and your house. The bathroom leak problem must be stopped and the internal wall mold problem eradicated completely to avoid future problems. The always helpful "wikihow" site below will provide more information on mold problems and how to remove mold from your home.

I agree with the previous poster. You need to deal with the mold in the wall before you worry about the new couch. It could be very expensive, so take the money you budgeted for the couch, and get that leak repaired and the mold eradicated.

How to get rid of mold on your ceiling? In my case, it came with heavy rains, which a lot of people are experiencing. I'm going to use a round hole saw and make an opening where I will mount what is called a muffin fan.

They look like the fans in desktop computers, only larger (almost 5 inches across) and higher speed. I found some on evilbay for about $14. The listing will say something like: 120mm X 38mm Cooling Muffin Fan 115 V AC 110 CFM (cubic feet per minute). That's a lot of air.

Mounting a big propeller-like ceiling fan will do nothing if you have something serious going on above the ceiling. It needs lots of ventilation which will dry out the mold. You can even spray Lysol into the fan once a day, but take it easy. There's a little more to the story, but there are the basics. It might help some desperate soul.

NEVER, never, never Remove Mold with Bleach. Google it. You'll see it is the worst. Use vinegar or if you have a Shark steamer steam it off -- then Make sure you buy mold resistance primer and paint - we had this problem in our bathroom because we have no exhaust fan and my husband takes really hot showers -- since we removed it- primered it - and repainted no more mold. But please don't use Bleach it can become toxic and worse from the combination Lynne

Dishwasher detergent gel (that has bleach in it). Rub it on and leave on. It will kill the mold and musty odor and dry, leaving a seal so that mold cannot grow in that same spot. KILZ brand paint is a good sealant paint for such areas of the home that tend to have moisture.

DO NOT ever use bleach! I just had the mold remediator here today and he said the spores sense the bleach and migrate. It a sure fire way to spread mold. You should use a mixture of borax, tea tree oil, and vinegar. Add peroxide to bump up its efficientcy in dealing with numerous species. Also, you can use Lysol. Never bleach. Never.

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.

Hi Sarah - The simple solution would be to use an oil based primer and paint over.

Yes, and you have to remove it and kill anything left over. It will continue to grow if you do not. J

I am looking for appropriate information on removing mold above my shower on the painted ceiling. The wrong paint was used at the time.

Make a mixture of bleach and water and apply to the ceiling. In short order the mold will disappear. Rinse with water. Use eye protection. You didn't say what the wrong paint was, that was applied.

After Foxrun41's remedy, always use a mold preventive prior to painting in an area subject to moisture, ie: Kilz..

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. ( 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.
