When you think of mold growth, it is unlike that concrete is the first surface to come to mind. Rather, drywall, wood, or insulation are the more common areas that mold grows. However, mold can still grow on concrete (especially in basements) leading to cosmetic damage and health concerns.

Getting rid of mold on concrete is a relatively easy process since the mold has a hard time getting past the surface of it. However, you should still take the correct steps to remove it so that it doesn’t cause problems for you or your home down the road.

How Does Mold Grow On Concrete?

Mold needs two things to grow: moisture and a food source. Concrete alone does not provide an adequate food source for mold to grow. However, when dust accumulates on the concrete, even in small amounts, it can serve as more than enough food for mold to grow. As materials in the dust like dead skin and bacteria serve as food, moisture is also needed for mold to grow. Unfortunately, in basements or other dark places where concrete is often found, moisture is also present. This can lead to mold growth on the concrete.

What Kind Of Mold Can Grow On Concrete?

Mold is versatile and can live on many surfaces. With that being said, most types of mold can grow on concrete. This includes dangerous black mold. Regardless of what type of mold is growing however, you should get rid of it as soon as possible to prevent it from spreading.

Can Mold Damage My Concrete?

Yes. Mold can do serious damage to your concrete if it is allowed to grow and multiply. Most common, mold can leave behind nasty stains that discolor the concrete and are very difficult to remove. While this not always be a big issue, if the concrete is decorative or in a visible location, it can be problematic. More dangerously, the acid that mold produces (which leaves the stains) can degrade concrete over time. If this is allowed to continue, then the structural integrity of the concrete can be severely decreased. This makes things unsafe and could lead to costly damages or repairs down the road.

How To Kill And Remove Mold On Concrete

Fortunately, removing mold from concrete is fairly simple. You should use a fungicide, such as a water/vinegar solution, to first kill the mold. Then, use a wet cloth or scrubber to physically remove the mold from the concrete. If you find that it has left stains behind, you may want to hire the help of a professional company. They can use techniques like sand blasting or even dry ice to help remove the stains.

How To Prevent Mold On Concrete

Preventing mold on concrete is no different than preventing mold on other materials in your home. You need to ensure that air humidity is low and that standing water is not allowed to make the materials of your home wet. Keeping moisture levels down is key to preventing mold growth. You can use a dehumidifier to help pull water from the air and keep your home dry. In addition, you can use HEPA air filters and periodic cleaning to help stop mold growth early and prevent if from occurring.
