People might not realize it, but concrete is important in our lives. If we didn’t have concrete, we wouldn’t have roads, buildings, or stable homes. Concrete is all around us and has been used for quite some time. However, like many other surfaces, concrete can get mold on it. How do you kill mold that is on concrete? Some people have basements made out of concrete. Keep reading because we will tell you how to kill mold on concrete.

Since mold can grow on practically any surface, concrete is one of those surfaces. While you might think of concrete as being only on the outside of the home, some people have parts of their home made out of it. Many basements are composed of brick or concrete. It is one of the places that gets the most mold, too. If you find mold in your basement, you may have to call a mold remediation specialist to help remove it. You should never let it sit because mold can do many bad things to your health.

Mold on Concrete

One of the main reasons that mold gets onto concrete is that it can retain a bit of moisture. It is easy for water to get into it because it is so porous. Because mold spores are practically microscopic, it can get into those small pores and grow there. Whenever that happens, it can take a lot of bleach and scrubbing to get rid of it. Whenever there is mold in your basement, it can spread to other areas of your home. It’s a good idea to treat it as soon as you can.

Safety is an important factor before you do any cleaning when it comes to mold. You should never handle mold without any protective gear on it. Remember to wear gloves and a surgical or sawdust mask to keep the fumes out of your body. Mold spores can also be floating around, so these safety precautions will keep those out of your body.

All it takes is a bit of bleach mixed with water, and you’ll have a good solution to kill the mold in your concrete. Using a hard-bristle brush is simply a matter of scrubbing down the concrete. If it is a concrete floor, a broom can also help. However, remember that bleach may lighten the tip of your broom.

Other Cleaning Agents

If you don’t want to use bleach, there are other options that you can choose from. While bleach is one of the most effective, some people have colored concrete or bricks that the mold is on. When killing mold, you can also use vinegar, a natural remedy for killing fungal growth. Vinegar is a powerful liquid that can kill over 80% of mold families. However, it may take a few applications.

Another choice is to use a detergent with borax in it. Borax is a substance that can kill mold in clothing and act as a good scrubbing mixture. Like bleach, it will get deep into the pores of the concrete with the right washing techniques. Scrubbing it down will get you the best results, but this may also require a few more applications.


Concrete is a very useful thing to have around you. Whether it is a road, a base for your home, or a driveway, concrete is essential for today’s living conditions. However, mold can get onto and into concrete like all other surfaces. This is a pretty bad thing, considering your basement could be made up of concrete. If you don’t know how to clean it, you might be looking at a bad time.

Even though mold can get on concrete, it is one of the easiest surfaces to remove mold from. You can easily scrub away the mold with bleach, vinegar, or borax. It may take a few coats and a heavy hand, but you can get rid of that mold as easily as anything else. You may want to keep a mold test kit on hand to ensure you got it all. Otherwise, you can call a mold professional to come and take a look at it.
