How To Treat, Remove, Clean & Prevent Mold | Remediation | No Bleach | Basement Doctor Columbus OH

White mold is often found in cool, damp environments such as in basements on walls and other structures. It is often confused with efflorescence, which is a mineral deposit that forms on foundation walls and other masonry surfaces due to water seepage. You can test to see if its mold by spraying it with water. If it dissolves, it is a mineral deposit if it does not, then its most likely white mold.

    Vapor Diffusion Through Foundation Walls

    Vapor diffusion is the movement of moisture in the vapor state through a material. It’s dependent on the permeability of the material and the driving force of vapor pressure differential. In a basement, vapor can diffuse from the wetter ground through concrete walls and floors toward the dryer basement interior. Vapor retarders such as foundation waterproofing and polyethylene slow down this process.

    Should You Paint Over Mold On Concrete

    Painting over mold is never a good idea on any surface. You will spread mold spores while introducing more moisture into the colony, providing further growth. It will look as if it was covered for a few days, and afterward, it will return to an area bigger than before it was painted. Remediation is the correct way to get rid of mold on concrete.

    Common Causes Of Mold In The Basement

    Cleaning Mold From Concrete Basement Walls

    As mentioned above, the main cause of mold in the basement is excess moisture, which is not a rare situation in a basement. Whether that moisture comes from the outside or from the inside, it is very important to get to the root of the problem in order to deal with it and prevent any further complications .

    So, where does the moisture, or water in a basement come from? Lets dig deeper.

    There are two main sources of water in basements:

  • An outside moisture source rain, groundwater, floods.
  • An inside moisture source a high level of humidity and different activities such as drying clothes.
  • Basements are below grade spaces in your home, which means that they are prone to water seeping in from the foundation walls, and window wells. Since these are the lowest parts of the home, gravity dictates that if water is present, it will flow towards the lowest area to settle.

    Two frequent causes of water in basements are rain and floods. Without proper grading, gutters and downspouts, rain often flows into the basement creating excess moisture for mold to thrive in. Flooding caused by heavy rains or rivers, provides the right environment for mold growth.

    When it comes to sources of moisture inside, we can talk about various causes, from ineffective insulation to excess steam that evaporates and raises the level of humidity . A high level of humidity and condensation creates the perfect conditions for both mold and mildew to spread in your basement.

    Cleaning The Mold With Hydrogen Peroxide

    A 3% hydrogen peroxide is a versatile cleaning solution for households. It can kill mold and mildews, too.

    Pour hydrogen peroxide into a spray bottle and spritz it over moldy spots. Let it sit for ten minutes and scrub the area to remove dead mold spores. However, if the mold problem is severe, you can repeat the process several times until you are completely satisfied with the results.

    Dehumidification Is Not A Permanent Solution

    Dehumidification can be used as a means of reducing the symptoms of humidity and odor in a basement, but it is not a permanent or complete solution. In fact, if a dehumidifier is used in a basement with moisture problems, it may cause greater damage. By drying out the basement air, moisture is drawn into the basement more rapidly causing efflorescence and spalling of concrete and further damage to interior finishes.

    Mold On Concrete Walls

    Black fungi on concrete walls mostly comes from moisture hitting and being absorbed into the wall. Before attempting to clean the walls, first resolve the moisture issue by redirecting downspouts and swamps from the wall. You could also try installing an interior footing drain to keep the water from the wall. Fix all water seepage from hose spots and taps. Also raising relative humidity in the house by improving ventilation would do the trick. You will then proceed to clean the molded concrete walls after fixing the moisture issue.

    Signs Of Mold On Concrete

    Mold and mildew removal from basement and exterior concrete surfaces

    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.

    Eps Xps Mineral Wool:

    SPUF is quite expensive so rigid insulation panels and a 2×4 wall with batt insulation can be a much more affordable option – but you need to know the right techniques for a succesful and mold-free wall assembly for a basement application – read on!

    Rigid insulation board against concrete adds R value, breaks the thermal bridge and raises the temperature of the stud wall, which helps prevent moist air from condensing. The stud wall allows for the installation of wiring, additional insulation and drywall.

    Drywall should be attached directly to studs, latex paint will act as a vapour retarder slowing any outward moisture migration while also allowing walls to dry inwards.

    You may hear that EPS is somewhat moisture permeable this is true, but only slightly so and not enough to be a problem. According to Professor Straube, two inches of EPS has a perm rating in the range of 60-75 ng, or 1-1.25 US perms, which is right on the cusp of what is defined by building code as a suitable vapour barrier .

    At that level of moisture permeability, an almost immeasurably small amount of moisture will be able to migrate into the wall, but with no interior vapour barrier it will pass through harmlessly. EPS, XPS and mineral wool are unharmed by moisture, and perhaps most importantly, EPS and XPS are unlikely to provide a breeding ground for mold.

    Remove Mold From Drywall/painted Walls

    Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.
