Can Mold Grow On Concrete
Wet conditions can cause mold and mildew growth on outdoor concrete like driveways, patios and steps. This growth usually occurs in damp or shaded areas that don’t receive a lot of sun or heat. Concrete, with all its nooks, crannies and pores, is actually a great incubator for mold. Wet, humid weather with warm temperatures only improves the growing conditions.
How To Clean Mold From Concrete
The best solution is to scrub and clean the affected areas with a mold-killing detergent, like RMR-86 Instant Mold & Mildew Stain Remover, or a simple solution of household bleach and water. Be sure to scrub aggressively to get down into the pores of the concrete. Let the detergent or bleach solution soak in for a while to ensure that all the mold is killed. After scrubbing, rinse with a power washer to get all the solid organic matter out of the concrete.
Once you’ve tackled the mold you can add color or an overlay to completely transform your concrete!

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.
Why Should You Get Rid Of Mold
Mold produce spores which are harmless in small amount, but very dangerous in large quantities.
Spores are airborne and can cause health problems to humans and animals when inhaled. Mold can also spread and cause serious stains on your surfaces, furniture and other fixtures. Mold affected surfaces are usually slippery and dangerous to walk on.

Yes, the sheet rock should be removed. This is necessary not only to clean up the existing mold, but to implement the prevention measures.
First, you need to identify the source of the moisture. Three possibilities exist. 1.) Condensation from the warm interior air hitting the cold concrete wall. This typically does not happen behind a well sealed wall , but its possible.
2.) Vapor emissions through the concrete. This occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface. In an uncovered wall, the water would simply evaporate into the air without causing an issue. The installation of the sheet rock traps the moisture, leading to mold growth. There are two solutions either keep the concrete exposed or install dimple board with a interior footing drain.
3.) Liquid water intrusion. Its possible youre having liquid water enter through the cold joint at the bottom of the wall. If this is the case, youll see more damage at the bottom plate/framing than higher up the studs. In most cases, the solution is an interior footing drain.
Signs Of Mold On Concrete
To know if you have mold growth on your concrete, you can first see what the growth looks like. Sometimes, a reaction with water and concrete creates the mineral growth called efflorescence. This can look like a white mold type growth coming out of your concrete structures.
If you see any growth happening on your concrete, contact Mold Busters to have a professional inspector visit your location and test the affected area to see if you have mold or not.
If the growth is brown, green, or black, the chances are that it is some mold colony growing on your concrete surfaces. At this point, you should not touch the affected area as mold spores are highly transportable via air currents. If you even walk by a mold colony, you could spread it to other areas of your home.

The answer to this question is straightforward. It would be best if you did not touch mold growing in your home by yourself. It needs to be remediated by a professional, who are appropriately trained and certified to inspect and remediate any mold in your home.

Furthermore, it would be best if you had complete personal protective equipment as well. Failure to do either of these will compromise the health of your home, as well as yourself.
Leave it to the professionals at Mold Busters, and feel safe that your home is in the right hands to diagnose and remediate the mold growing in your home.
Fallback On Commercial Cleaning Products
If vinegar or bleach do not work, or you would prefer to move directly to a commercial solution, you should have no trouble finding effective products at your local garden center or home improvement store.
You can opt for a simple patio or deck wash-type of product that is used for general cleaning if your mold or algae problem is mild. If your hardscape has been stained from the mold or algae, you may need to opt for a mold stain remover. For example, if you just purchased a home where mold or algae has been allowed to flourish for an extended period of time on concrete, brick or paving stones, there may be stains that require a product specifically designed for mold and algae stain removal.
With most of these products, you will spray the area, allow it to work its magic for a few minutes, scrub with a deck brush or push broom, and then rinse the area with water.

Is Mold On Concrete Dangerous
While mold on the exterior of a home can be unsightly, mold growing on concrete surfaces in the home interior can be a dangerous health hazard. Black mold can cause serious health problems and must be dealt with as soon as it is detected inside the home.
Black mold can aggravate allergies, cause asthma attacks and irritate the eyes, nose, and throat. If left unchecked, it can also cause significant property damage, especially if it spreads beyond concrete to the wood construction.
If removing mold from indoor space, its important to use protective gear. Extensive mold problems discovered indoors require expensive mold mitigation efforts from licensed professionals.
Dry Out The Affected Area
Mold thrives on moisture, so you need to make sure the area is dry. If you dont, the mold can spread its spores in the air. This will make it harder for you to clean, and it might cause an allergic reaction.
Try to expose the area to direct sunlight to dry it out. If you cant, use a fan or heater thats made for the outdoors.

White growth on concrete is nearly always efflorescence, not mold growth. You can verify this by spraying a bit of water on the suspected growth. If its efflorescence, it will disappear as the crystals are dissolved by the water. If its mold, it will flatten, but remain visible.
I recommend removing the rubber mats for now. The impervious nature of the mats will prevent the concrete from releasing the moisture. After a week or so, put a couple of mats back down. Peel them back a few days later and look for signs of moisture on the underside of the rubber. If you see moisture, pull them off and allow the concrete more time to dry.

Use Vinegar Or Bleach
When you start to see a little mold or mildew on your shower curtain liner, you throw it in the washer with some bleach or vinegar, and it comes out clean and mold free. The same thing can happen for your hardscapes. Bleach should not be the first line of defense for folks who have plants or grass bordering the patio or walkway that has mold, but this is another option you can try if pressure washing does not work.
If you are going to try this approach to remove mold or algae, first try a mixture of white vinegar and water to spray down the area and kill the mold. Vinegar is a great way to get rid of weeds, so you do not have to worry about overspray getting on weeds, but you do need to make sure you do not spray vinegar on wanted plants and that the vinegar does not run off into a natural grass lawn or flower bed. After you have sprayed the vinegar solution on the area and allowed it to work its magic for a few minutes, you may need to use a deck brush or scrub brush to address stubborn areas.
You will then want to rinse the area well with water.
If you opt for a bleach solution to remove mold or algae, you will need to rinse the area after application. If the mold or algae has stained your hardscape, you may need to repeat this process a second or third time to remove the stain.

I Have A Major Moisture Issue Along One Wall In Basement Particularly Behind Furnace Duct
The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.
If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.
