How To Clean Mold Or Mildew From Concrete And Stone

Perhaps your area was very humid last year, or maybe its always humid where you live. Humidity creates a cozy environment for mold or mildew to grow. Last summer was very humid in Brooklyn. Green mold or mildew started growing on practically every surface, from concrete to stone, to benches and trees! I needed to learn how to clean mold or mildew from concrete and stone.

I watched a few of my neighbors use a solution of diluted bleach which is effective. Then I learned about another method from a Facebook group I am part of, DIY Home Improvement Projects Wet and Forget . As bleach can sometimes alter surfaces, I thought Id give this product a try first.

Mainly, I was looking to get the green off my property as its unsightly and makes my house and front area look poorly maintained. Who wants green all over their façade?

The directions for Wet and Forget say to dilute the product with 5 parts water to one part Wet and Forget, and to use a spray bottle and spray it on a dry surface.

The mold around my home was on a few surfaces the front stairs, stone on the home, and the wall around the front of the property.

It took an exceptionally long time to cover a surface with my spray bottle, as I had so many affected surfaces. I am wondering if it would be more efficient to dip a cloth in the solution and coat the surfaces this way instead? Next time.

With about half the surfaces covered, I waited.

And here is the same stone about 24 hours after it was treated:

Its difficult to determine from the photo whether this is mold or efflorescence. An easy way to distinguish between the two is by flicking a bit of water on the surface. Efflorescence will dissolve in water, mold will just mat down a bit.

Either way, it likely indicates vapor emissions moving through the concrete. You can verify this by taping a piece of plastic to the concrete. Recheck this in a few days. If you find condensation on the backside of the plastic, you have a vapor emissions issue.

In a garage this is not a problem, as long as you keep sensitive items off the floor. The vapor will eventually evaporate from the surface. Do not install carpeting on any concrete showing signs of vapor emissions! This will lead to major mold problems.

    What Causes Black Mold On Concrete

    How to take mildew out of concrete

    Mold can grow on concrete for a number of reasons. Like other types of mold, black mold grows in areas where the conditions are right for them. Black mold will grow on surfaces with high moisture, which may be due to leaks in windows, roofs, pipes, and water tanks. The spores of black mold are transferred from one place to another through wind, animals, or water sources. If a wet concrete surface is exposed to black mold, the mold will thrive. Black mold reproduces quickly, and a small patch of it can multiply within a short time. This means that your concrete surface could be covered in black mold within a short time.

    If the concrete is in a basement, the black mold may be caused by a leak from outside or faulty plumbing. Homes with high humidity also tend to have problems with mould growing on surfaces as well. Outdoor concrete, such as a patio, usually grows mildew when it doesnt dry completely after its been soaked. This is typical of concrete thats well shaded.
