Step #1. Select a cleaning method

Step #3. Use the solution

Apply your selected cleaning product to any noticeable moldy patches on the concrete with a heavy-duty sponge or scrub tool to ensure thorough coverage. Using a stiff brush, scrub the spots thoroughly. Mold-killing detergent should be applied to the locations and washed thoroughly.

 

Step #4. Let it soak and rinse

If the molds do not appear to be disappearing after a few minutes, let the solution soak for a few more minutes. Then, using the solution, scrape the affected areas until the mold is completely gone.

Rinse it properly and use a hot water pressure sprayer to get the job done as quickly and efficiently as possible. If you do not have water pressure, you can also use an ordinary hose to clean the surface.

 

Step #5. Inspect

Inspect the area thoroughly for any mold that may have remained after you dry it. When there is still noticeable mold, thoroughly rinse the area and attempt one of the more powerful solutions you haven’t tried yet, such as bleach solution or a specialized cleanser.

 

Step #6. Deep clean removed items

You should thoroughly clean items you have previously laid aside before being returned to their original location. Upholstered furniture with evident mold will need to be discarded or completely rebuilt by a professional to avoid further contamination.

How do you stop mold from growing on concrete?

The most effective method of preventing mold growth on concrete is to avoid it from occurring. One process of accomplishing this is to eliminate moisture, which is a necessary component for mold growth.

Start reducing greenery that produces gloomy patches on a driveway or path that never sees the light if you have concrete terraces, driveways, or walks in your yard. Fractures in the concrete, which can absorb moisture and mold growth, should also be addressed. You can use concrete repair products to fill in these gaps.

If this isn’t an option, consider sealing the concrete with a sealer suitable for outdoor use in the affected area. Moisture will not penetrate the pavement or pathway as a result, and you will be able to eliminate the atmosphere necessary for mold growth.
