There are several effective ways to remove mold from concrete depending on where the concrete is located. According to Kevin Bristol a mold remediation expert, you must determine why the area is growing mold and water-proof it to prevent further mold growth. This article will address removing mold from concrete and preventing it from coming back.

Kevin Bristol, President of Advance Mold Remediation states, "concrete needs to be scrubbed down" in a process "called wire brushing, where you apply a chemical biocide to the actual concrete and you scrub it until the mold is gone". In some cases you can remove and clean up the mold on your own. If the area is larger than 10 or 12 feet you should call a mold removal specialist. If you, "do try to do it on your own you need to have the right equipment and chemicals. You should also wear a respirator, not just a paper face mask and make sure the area is properly ventilated so that the odor will dissipate" states Bristol. When mold is embedded in concrete, using a biocide is the only cleaner that will work permanently and usually this kind of chemical is not available to the general public. If the area is small and you would like to try to clean it yourself, use a wire brush and scrub it with ammonia. You can use a solution of bleach and water, but never mix bleach and ammonia together as this will let off poisonous fumes that can be very harmful.

Once the mold is cleaned up you will want to make sure that it does not return. First, determine why mold is growing there. Is there a leaky pipe? If so, have the leak repaired. If the concrete in the basement is moldy you may need to have a professional come out and water-proof your floor and walls. A professional water-proofer can do a test on the cinder-block and determine the moisture level. If the moisture level is too high you will need to have the basement sealed. Basements are the most common place you will find mold. Be especially diligent in detecting and keeping mold growth under control in your basement. Using an air conditioner reduces the humidity in the air and this will reduce mold growth. You can also us a de-humidifier. Keep the humidity level in your home below 50%. Bristol explains that you can paint the concrete with an antimicrobial coating or a dry lock paint that retards mold growth. A weekly scrubbing down of an area prone to mold will keep it at bay. Once the mold growth is under control you can then move to scrubbing the area once a month. If you have a flood in your home you need to lift the flooring and dry out the concrete or you might end up with a mold problem.

The Minnesota Department of Health states, "Mold should not be permitted to grow and multiply indoors. When this happens, health problems can occur and building materials, goods and furnishings may be damaged." You would be wise to get rid of mold as soon as you detect it.
