How To Clean Black Mold From Pavers

Mold and mildew removal from basement and exterior concrete surfaces

It is best to clean pavers when the weather is sunny. Cleaning on rainy days will not allow the pavers to dry after cleaning. Check your areas weather forecast before you begin just to be sure.

A mixture of one part bleach and three parts of water can do the trick. Use your hard brush dipped into the solution to scrub off the mold from your pavers.

You can also use a pressure washer to blast off any black mold remnants.

Bleach is a powerful cleaning agent, which means it can discolor the pavers. Not to worry, you can always repaint with a paint sealer of your choice.

Commercial paint sealers can be found in most home improvement stores.

Once again, wait until the pavers are completely dried before applying the sealer. The natural sunlight and outdoor breeze are all it takes.

You can wait for two to three bright sunny days to ensure all the moisture has disappeared.

What To Do When Mold Is Lodged Too Deep Into Patio Cracks

Cleaning surface mold from your concrete patio isnt much of a challenge.

This is because they are visible and easy to reach. As for mold that is lodged just below the surface of the patio, you can kill them by pouring enough amounts of the solution so it can sink in and do the job.

But what about mold that is lodged too deep? Well, thats a whole different ball game and more thorough approaches have to be employed.

It is possible that your cleaning solution will not go deep enough to kill the buried mold. This means the surviving mold can grow back on the surface over time.

In such a case, you will need to hire a mold inspector to determine the extent to which mold has penetrated the sub-surface of your concrete patio. Inevitably, the patio has to be dug and redone.

This will cost you some money, but if youre serious about eliminating all traces of mold in that area, then it needs to be done.

Why You Should Remove Mold From Your Patio

Your patio is indeed located outdoors, and you may think mold growth in that area is not an issue. Well, it is.

Mold doesnt look good, so allowing it to grow on your patio affects the beauty of your home. You wouldnt want your visitors coming across such an eyesore when they make their way into your home.

Secondly, mold is a health hazard. It causes allergies and can affect those with respiratory problems. This is a problem for those who spend a lot of time hanging out on the patio.

Your children and pets can also be exposed to it too!

Thats not all, mold growth can actually compromise the structure as a whole. This wont happen overnight, but you will notice serious deterioration in years to come.

Last but definitely not least, mold has an unpleasant smell, especially when they occur in large amounts. Why leave your front door with a musty smell?

That being said, follow the steps below for patio mold removal.

What Can You Do To Prevent Mold In A Basement

To prevent mold from reoccurring or growing at all, you can take the following steps:

  • Use a negative air pressure machine to filter and clean the air in your home and basement. The machine filters all the air out of the room using a process called ducting. During this process, it filters all mold spores that can engender mold growth in the right conditions.
  • Correct the moisture problem by fixing any leaks and cracks in the foundation. If your sump machine has failed, ensure it is set and running again.
  • In areas with high humidity, install a dehumidifier and a humidity gauge to monitor the humidity levels. Always ensure that moisture stays below the 60% range at all times.
  • Seal your foundation using materials such as dry gypsum wall and a primer. That way, any rise in surface water due to flash floods doesnt find its way into your foundations and, subsequently, your home.
  • Purchase a mold inhibitor and mix with the paint, which you will use to paint the walls of your home and basement.
  • Check to ensure that your gutters arent clogged, and all water is deposited far away from your home. Also, get your gardener to ensure that the area surrounding your basement slopes away from the foundations of your home.
  • Types Of Basement Mold

    Various types of mold will infest your basement. While they are all hideous, not all of them are toxic to humans.

    Molds can be divided into two categories:

    • Allergenic
    • Mycotoxin/black

    Allergenic molds usually pose no health risk unless you are extremely sensitive to molds or asthmatic. Black molds, on the other hand, produce a toxic chemical called mycotoxins and are particularly harmful to humans and pets.

    Here are the common types of molds that can infest your basement.


    Aspergillus is one of the most common household mold species. There are different types of Aspergillus, and most of them thrive well indoors. Some of the Aspergillus molds are allergenic, but some are mycotoxin and should be removed by a specialist, especially if it is something like black mold.

    This fungus is dark green and found on damp walls, ceilings, and even furniture. It flourishes in humid environments, but can also grow in areas that are dry with high levels of humidity or condensation.

    What You Need To Do First

    Before you get started with removing mold from concrete, you need to gather the right materials.

    You will need:

    Some people are allergic to mold. They can get very sick when they come into contact with it. If this is you, then wear a dust mask and avoid getting it on your skin or in your eyes.

    A Warning: Do not use metal brushes or steel wool to clean concrete. You should also avoid mixing bleach with other household cleaners. This could create toxic fumes.

    Products And Tools Youll Need To Get Rid Of Mold In Basement Areas

    • Eye protection: When disturbing mold spores during cleaning or simply using harsh chemicals like bleach, youll want to keep your eyes protected.
    • Disposable gloves: Handling mold and moldy material is reason enough to wear gloves, but it can also protect your skin from irritation when using cleaning products.
    • Stiff-bristled brush: To effectively remove mold stains on porous or rough surfaces, you will need a brush that can scrub away mold without the bristles collapsing.
    • Sponge: On softer or smoother surfaces, a disposable sponge may be all thats needed to stop mold spots from becoming more significant problems.
    • Mold stain remover: Though not essential for actually removing mold, youll likely find a dark stain on the material that the mold was growing on and youll want a product to remove it. Plus, removing the old stains can make sure that you recognize new mold growth later.
    • Bleach: A solution of 1 cup of bleach to 1 gallon of water is enough to kill mold on surfaces, according to the CDC.
    • Cleaning bucket with measuring marks: Ensure the right measurements for your bleach solution with a good cleaning bucket.
    • Spray bottles: Whether for bleach or one of the more natural solutions discussed below, a spray bottle will help you treat mold spots.
