    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.

    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.

    Yes, it does. You can use vinegar to kill mold because it is acidic. White vinegar is recommended for killing mold because scientific studies have shown that it can eliminate up to 82 % of mold spores. It is also advantageous to use vinegar because it is known to have disinfecting properties that will kill the viruses or bacteria on surfaces. You can use vinegar to do away with mold on hard nonporous and porous surfaces since it can seep into surfaces. When dealing with vinegar, be sure to use personal protective gear to prevent it from getting into contact with your body because it irritates. Use a liquid sprayer for a smoother application on the affected area and dry it before cleaning it.

    Does Bleach Kill Mold On Concrete

    Yes, bleach can kill black mold. Although mold grows in most surfaces with moisture, you can use bleach to kill it and fungi growing on hard impermeable surfaces. You can also use bleach to kill mold that grows on impervious surfaces like tiles and tubs but not on porous surfaces. This is because mold on permeable materials spread their roots deep. When you use bleach to kill them, you will only be wiping it from the surfaces. This means that it will re-emerge after a short while.

    Depending on the problem, you may have to perform significant repairs to stop the moisture. If its a leaky pipe, condensation in your HVAC system, or a crack in a doorway or window, make sure to either repair or have a professional repair it ASAP.

    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

    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.

    Mold can grow in your home wherever theres an abundance of moisture, especially when its allowed to remain for extended periods of time. Mold usually appears on walls, ceilings and floors of homes where moisture management is not at its best.

Mold and mildew, for all intents and purposes, are essentially the same thing mildew is generically used to describe many minor mold problems in the home, such as on shower tile grout. However, some molds can become highly toxic to people if left to prosper. Mold can cause allergic reactions, asthma and other respiratory complications, and is especially a risk for small children, the elderly and those with existing respiratory illnesses or weakened immune systems. Mold can appear in many shapes and colors, none of which accurately determines the actual species of mold. However, it does commonly present itself in various tints of black, white, green or blue, and in many combinations of these and other colors.

    Mold growth on concrete is due to several different reasons. However, its leading cause is water damage. Water damage may be due to improper drainage or a sump pump.

    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 Do Professionals Remove Mold From Concrete

    It is only advised that you tackle a small area of mold. If you have an area that is more than 10 feet and covered in mold, you should leave it to the professionals. It is also a good idea to call professionals when you are removing mold from a business building or a school building, because it is extremely important that it is completely removed in these situations.

    Though your vinegar or bleach will work to kill your small area of mold, professionals have a bit more of an elaborate way of doing it.

    First, they contain the areas infested with mold and discard any items that have been contaminated . Many professionals use an antimicrobial chemical that removes mold and stains and then use a sealer to make the treated areas more resistant to water damage and mold.

    So the good news is, whether you are looking to remove a small area of mold in your house or tackle a huge area, it is possible!

    Cleaning mold off your concrete will be easy after reading this, and if it is too out of your comfort zone, feel free to call a professional in your area.

    Mold can be harmful to your health, so it is important to know how to remove it from all sorts of surfaces, including concrete floors. If mold appears, it is vital to get rid of it quickly, as the longer it sits, the more it will spread and the harder it will be to get rid. However, unless the mold has been sitting on the concrete floor for quite a while, removal is not an especially difficult job.

    Step 1 – Scrub With a Broom

    Put on rubber gloves and a dust mask before you begin to remove mold because cleaning can stir up harmful spores that can be detrimental to your health. Then, mix up water and detergent in a bucket at a ratio of four parts water to one part detergent. Pour about half of this solution on the concrete floor and work it over the deposits with a broom. This will help loosen the mold and make it easier to remove. Cover as large an area as you can.

    Step 2 – Mop

    Empty the bucket and refill it with clean water. Mop the area, allow it to dry, and see how much mold is left. You will have removed quite a lot by adding the solution to the floor but it is unlikely you will have cleared all of it. If any remains, you will need to take further action.

    Step 3 – Add Bleach

    Step 4 – Use Trisodium Phosphate
