Never put off removing mold from your walls – cleaning it as soon as possible is the most important thing. In this guide, we will show you how black mold removal works, what chemicals to use and when.

Is mold growing on your walls actually that big of a problem? In short, yes, it definitely is. Removing mold is always necessary, no matter where or in what quantity it’s found. The question remains: What is the best cleaning agent for getting rid of mold?

Exposure to its spores and gaseous by-products along with the chemical cleaning agents can prove harmful to your health. This is why you should carefully consider how to clean and remove the mold in your home. Here are some tips to get you started:

1. Removing Recent Mold Growth

You can usually use a mild anti-mold agent if the problem is not too widespread. Cleaning agents containing alcohol (80 percent ethanol – beware of the fumes!), hydrogen peroxide (three to ten percent), or sodium bicarbonate (soda ash, five percent) are often quite effective.

If these mild cleaners aren’t enough to clean the mold completely or you can’t avert the humidity that caused it, it may be time to try a more intensive cleaning agent. Some chloride-containing cleaners can destroy the spores in as little as ten seconds. These chemical products are very effective, yet you should only use them if absolutely necessary due to their own risks to your health. Be sure to read the directions carefully when removing mold with such heavy-duty products.

2. Removing Established Mold Growth

If the mold has been present on your walls for a while, black mold removal becomes a bit more complicated. At this stage, the mold has probably already permeated the paint, the wall paper and sometimes even spreads into the plaster or drywall. When this happens, removing the mold will not be possible by just cleaning the surface. You will need to have a professional assess the situation and likely completely replace the colonized material. If you take this task upon yourself, it is important that all materials affected are removed carefully and the area checked thoroughly upon finishing.

3. After the Black Mold Removal: Find out, what Caused It

Simply removing mold is not an adequate solution in the long run. More important is to find the root cause and prevent its further spread. If you don’t take the time to do this, don’t be surprised when it pops up again around your home. The most common reasons for mold in homes are poorly-insulated walls, high humidity (from plants, bathtubs/showers, drying laundry, etc.), improper ventilation, and insufficient heating.

How to Prevent Mold

  • After removing the mold, you should treat the affected areas with fresh plaster or paint. Lime plaster and lime mineral paint (often a bit more expensive) offer great advantages in that they allow water to pass through and evaporate. The lime also works as a mild fungicide.
  • Avoid putting wallpaper or textiles on or near the affected areas. These can serve as a breeding ground for new mold colonization. Some types of mold are known to cause allergies and certain forms of lung disease as the spores can be transmitted through the air, come to rest on your face and skin, and make their way into your respiratory tract.
