How-To Clean Mold from Concrete | SealGreen.com | 800-997-3873

For those who followed the instructions, scrubbed hard, and used the solution a few times without much luck, know that sometimes tougher measures are called for. A product like Wet & Forget should do the job. While the label says it is bleach-free, phosphate-free, non-acidic, and safe near plants and on all outdoor surfaces , do take caution when using this product. Wear rubber gloves and avoid unnecessary dripping into your garden or grass.

Follow the directions on the container of the cleaning product, making sure that the previous cleaning solvents have been thoroughly rinsed off with a strong blast from the hose. While the product used may claim that scrubbing isn’t necessary, it will probably be necessary to have those sleeves rolled up continue to scrub the moldy/mossy area until it’s free of all the green stuff.

Try revisiting the area in a week or two to keep on top of the mold and mildew. Persistence will pay offâif you regularly do a light cleaning of the space, more thorough cleanings every few months won’t be necessary.

How To Clean Mold From Concrete Basement Walls With Hydrogen Peroxide

Hydrogen peroxide is a versatile and effective cleaner thats a fungicide, virucide, and bactericide. There are dozens of peroxide uses for around the home, both inside and out.

Disinfecting with hydrogen peroxide will kill virtually anything thats growing on your basement walls, including mold! Its also ideal to clean concrete basement floors, too.

If youre wondering how to clean mold from concrete basement walls or need to start cleaning brick walls in the basement or carport with this concrete cleaner, heres how.

To kill mold on concrete basement walls or for an ideal DIY mildew remover, pour 3% hydrogen peroxide into a spray bottle. Saturate the walls with the peroxide, then let it sit for up to 30 minutes. Clean mold off walls by scrubbing the area thoroughly with a bristle brush after about ten minutes to help to lift any residual mold out of the pores in the concrete.

If you can, hose off the walls or scrub them down with warm water to remove any cling-on spores when you finish and leave the walls clean and shiny. Dry with a clean towel to eliminate water spots that could encourage more mold to grow.

Peroxide is an excellent option not only for mold removal but to get rid of other types of stains, as well, especially for how to clean white walls that may have mold or mildew.

Liquid Laundry Detergent And Household Bleach

To clean mold off concrete, begin by cleaning the concrete surface with a hose, removing as much black mold as possible. If the concrete is located indoors, use a sponge to scrub away the mold. A scraper is also an effective tool for removing the mold from concrete.

Keep in mind that though these methods are effective, physically scrubbing or scraping the mold away will not remove the root, which is embedded inside the porous concrete. If the root is still intact, the mold will simply grow back.

Killing mold beneath the concretes surface requires cleaners that can penetrate the concrete. While bleach is effective and kills mold, its surface tension does not make it ideal for soaking concrete. Laundry detergent is a better option.

Create a cleaning solution by mixing a cup of laundry detergent with a gallon of water. Use a sponge or brush to apply the solution to the floor. The detergent will soak into the concretes pores, killing the black molds roots.

Use a scrub brush to ensure the solution penetrates the concrete and to remove the molds roots. When complete, rinse off the concrete with clean water. If outdoors, use a hose. If inside, use a mop.

Repeat this process if any mold is still present. Dry the concrete with a fan until it is completely dry.

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.

    How To Kill Mold In Your Basement With Borax And Warm Water

    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:

    • 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

    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.

    Use A Pressure Washer To Get Rid Of Mold

    The hot water pressure washer is a super ideal method that you can use to get rid of and remove the stubborn mold. Once you remove the dirt and other debris, you will be required to blast mold using hot water. To do this, you will need a power washer.

    Hot water assists in killing fungi cells and other stubborn microorganisms. However, it is essential to be careful while using this method, especially in situations where other plants are present in the surrounding patio.

    Once you have splashed the hot water, you will realize that the stubborn and sticky mold has become soft. As such, you will then be able to scrub the mold using a deck brush.

    Besides, you can use a steam cleaner to kill the mold on hard surfaces.

    Finalize this by replenishing the patio joint that your powerful jet water may have displaced.

    Preventing Future Mold Growth

    You should seal the concrete with a good-quality acrylic sealer designed for exterior use. Let the concrete dry at least 2 or 3 days in rain-free, sunny conditions before sealing. I recommend using a low-solids solvent-based sealer to allow for better breathability, especially considering the warm, humid exposure conditions.

    How To Remove Mold From Painted Wall

    Anyone that has a moisture of humidity problem in their home will end up having mold on the walls.

    That is unless you took the right steps to fix the moisture problem.

    If you have mold growing on your walls, like most people, you probably cleaned it with bleach or some other mold removal product.

    However, to your surprise, it came back days later.

    If the growth returned, you probably didnt fix the moisture problem correctly the first time around.

    Mold growing on painted walls can be resilient.

    If you fail to get rid of the moisture source, it will keep coming back no matter how many times you try to clean it or paint over it.

    The regrowth happens because chemicals applied often will not penetrate deep below the surface where the roots continue to grow.

    When the roots keep getting a constant moisture source, the mold continues to develop.

    Applying mold removers is only a temporary measure and only stops mold development when the killing agent stays active.

    Once the killing agent evaporates, the regrowth will just happen again and again. That is until you find and stop the moisture source.

    Signs Of Mold On Concrete

    How Basement Mold Is Removed | This Old House

    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.

    Banish Mold Infestations With Professional Help

    What gets rid of black mold? Most of the cleaners weve mentioned can snuff out black mold infestations, but we recommend getting professional help for significant black mold growth. This is because Stachybotrys chartarum, or black mold, can be harmful if breathed in large quantities.

    If a basement mold problem is really severe, mold removal specialists might turn to fumigation to eradicate the infestation. Whichever method they choose to take care of your mold problem, you can rest assured that a professional will do a thorough job to prevent the black mold areas from returning.

    If you dont eradicate the source of the moisture that caused the mold, you could see more mold, but a professional will eradicate all mold spores and roots from an infestation so that the same colony cannot grow back, particularly in the same area.

    Dehumidifiers and waterproofing paint can be useful for helping to stave off future mold issues. Wet, moldy surfaces like carpeting and drywall are often too far gone to be salvaged and need a replacement instead.

    Tools And Protective Gear

    Black mold removal requires a few household tools and some more advanced protective gear. Youll need a bucket, bleach, disposable rags, rubber gloves, heavy-duty garbage bags to dispose of contaminated material, and a wire scrub brush. Its also necessary to use good protective gear. For black mold, an N-95 respirator is the minimum advised. Youll also need goggles to protect your eyes from spores in the air.
