How to Get Rid of Black Mold on Drywall

  1. Assess the Damage

You must first assess the damage caused by the unpleasant black mold to know whether or not you can remove it by scrubbing or if you have to remove and replace the damaged part entirely.

  1. Shop for Materials and Tools You Need for the Project

Run to your local hardware store and buy the shopping list mentioned above. You can also choose to use natural products to remove molds if the damage is not that big. Just keep in mind that rubber gloves and masks are a must, especially since you are doing this project on your own.

  1. Prepare the Area

Clean the infected area and remove anything that might be damaged by bleach and other commercial mold remover products.

  1. Remove Mold

  • Wear appropriate protective pieces of equipment such as gloves and respirator before you begin. Open windows to get air moving and to help disperse fumes from the bleach solution.
  • Killing mold with bleach is effective. It kills any kind of mold it comes in contact with on any non-porous surfaces. However, killing mold on porous surfaces such as tile grout, wood, and cement block can be quite difficult. This is because chlorine from the bleach doesn’t reach the root level of mold growth. It leaves moisture content which promotes more mold to grow on the same surfaces that were just cleaned.
  • In making your bleach solution, combine 1 cup of bleach to 1 gallon of water and mix thoroughly. You can put the solution in spray bottles to make it easier for you to apply it evenly to the infected area. You can also opt to use sponge or towel to wipe the solution onto the infected areas.
  • If necessary, you can use a brush to scrub the infected areas and wipe away. For larger surfaces, you can vacuum with HEPA filters.
  • Do not rinse the cleaned area immediately. Allow the bleach solution to completely disinfect the infected area.
  1. Repaint the Surface

You might need to repaint the bleached area to make it look like nothing happened.

Other Natural Mold-Killing Solutions You Can Use

If you are only dealing with a small infected area, you can use other natural mold-killing solutions that are readily available in your kitchen. Just replace the bleach solution and follow the same procedure as above.

  1. Baking Soda and Water

  • Mix baking soda and water with a 50/50 ratio.
  • Follow the same procedure above but do not rinse. Baking soda will leave a thin layer of protection to avoid recurrence of mold.
  1. Distilled Vinegar

  • There is no need to mix the vinegar with water to make a solution. Vinegar in itself is effective in killing mold.
  1. Hydrogen Peroxide and Water

  • Make a solution of 2 parts water and 1 part of 3% hydrogen peroxide.

How to Keep Your House Mold-Free

According to experts, there is no way you can eliminate mold and spores entirely. The key to mold control is moisture control. Here are some ways you can control indoor moisture.

  1. Fix Your Water Infiltration System

Repair any water leaks as soon you find them. Not only does it pose potential structural problems, waterlogged areas allows mold to accumulate and thrive. If it gets out of control, you might have to remove all mold-infected areas and replace them.

  1. Decrease Indoor Humidity

Humidity allows mold spores to grow. With proper air ventilation, there is a huge chance you can keep your home free from mold spores. Do not allow air to stay warm and stagnant. Invest in air vents, conditioners, and dehumidifiers in your bathroom, kitchen, and large appliances such as washers and dryers.

  1. Make Sure You Have Proper Insulations

You can prevent condensation by insulating your roof, exterior walls, windows, and pipes to minimize the potential for moisture to form from condensation.

Conclusion

So that is how to get rid of black mold on drywall. We cannot stress how important it is to handle it with care by not mixing different cleaning agents together, wearing protective pieces of equipment, proper air ventilation, and not let children and pets in the work area. Control mold growth by controlling the moisture and humidity in your home.
