How to Remove Mold From Your Painted Walls? – DIY

Mold poses health risks. It can cause allergic reactions and irritations. In extreme cases, it can lead to infections and illnesses.


Like most fungi, mold spores spread and cause more damage over time. It’s crucial to use remediation methods to remove it as quickly as possible. Professional services are your best solution. They will get rid of mold efficiently to ensure it’s completely removed.


However, individuals who want to avoid expenses and are familiar with mold removal may attempt to DIY the issue. Professional services may still be necessary to ensure the mold is gone. This article will explain how to remove mold from your painted walls to promote a healthy environment in your home.


What is Mold?


Mold is a natural part of the environment. It can be found anywhere oxygen and moisture exist. It is typically found in soil, on plants, or on dead and decaying matter.


Outdoor mold helps nature by breaking down organic matter. But indoor mold should be avoided. It can cause a variety of health conditions including:

  • Runny nose
  • Red eyes
  • Skin rashes
  • Headaches
  • Dizziness
  • Asthma attacks
  • Sneezing


How to DIY Mold Removal


Here are the steps you must take to remove mold from your walls.


Take Safety Precautions

Mold spores may be released during the removal process. The proper safety precautions will protect you and your home environment.


  • Wear Protective Gear: Wear gear to protect any part of the body that mold can infiltrate. Wear work gloves on your hands, goggles on your eyes, and a respiratory mask to prevent lung irritation.
  • Open Doors and Windows: Ventilate the area to circulate clean air and prevent allergens from spreading.
  • Install Barriers: Hang a plastic sheet to isolate the area and prevent spores from spreading.
  • Set up Disposal Methods: Have a trash bag handy so you can dispose of contaminated materials immediately. Seal the bag and take it out to the dumpster when the job is completed.


Removing Mold


Once you have made the area safe, you can begin your mold removal processes. Here are the steps to follow.

  • Assess Mold Damage: Assess the affected area to ensure you are targeting all existing mold.
    Choose a Cleaning Solution: There are several cleaning solutions you can use as follows:
  • Bleach and water: Mix water and bleach in a 3:1 ratio. Bleach is a strong and effective cleaning solution, but it can damage surfaces. It can also irritate your skin, eyes, and lungs.
  • Vinegar and water: Mix vinegar and water in a 1:1 ratio. Vinegar has natural disinfecting properties. It’s also gentler than bleach. However, it may not be as effective in removing stubborn mold.
  • Commercial Mold Removal: There are products that you can buy in the supermarket and at hardware stores that are designed to clean mold. However, they are not all created equal. Read reviews in advance to determine which products will work best.


Apply the Solution


  • Apply the solution to the moldy area with a sponge or spray bottle. (Start with a small portion of the wall to ensure it won’t strip your paint before proceeding).
  • Let the solution sit for at least 10 minutes.
  • Scrub the area with a sponge or brush.
  • Rinse the area.
  • Dry thoroughly with a clean towel.
  • Repeat if necessary: You may have to repeat the process if you are unable to remove the mold completely. If the mold persists after multiple cleanings, you may need to call in a professional.


Address the Cause

It’s essential to determine what’s causing your mold issues. If you don’t address these issues, the mold will keep coming back. Common causes include:

  • Leaky foundations: You may have leaks in your exterior and interior walls that are causing mold growth. Foundational issues are difficult to detect. High water bills are a sign of foundational problems.
  • Damaged Walls: Damaged walls may let water in and cause mold growth.
  • Leaking Roofs: Leaking roofs can let water into your home. When the water stagnates, it can cause mold spores to germinate.
  • Leaky Pipes: Leaky pipes are a common cause of mold. If you detect mold caused by leaky pipes, you may need to call a professional to solve the issue.
  • Poor Ventilation: Ventilation will circulate air through the home and prevent allergens from spreading. Ventilate high-humidity areas like bathrooms and basements to prevent mold growth.
  • Flooding: Flooding can cause water damage and mold growth. Homeowners should call in a specialist directly after flooding occurs to minimize damage.
  • Poorly Constructed Walls: Poorly constructed walls allow for uncontrolled moisture in the form of condensation, liquid flow, and capillary action.


How to Prevent Mold

Keep humidity levels in your home below 50%. Air conditioners and dehumidifiers will keep humidity levels under control. You can also purchase a meter to monitor humidity levels throughout the day.


  • Ventilate Your Home: Use exhaust fans in your bathroom. Air out humid spaces. Make sure your clothes dryer vents outside your home.
  • Tend to Leaks: Fix leaks in your roof, walls, and plumbing system to keep mold from forming.
  • Add Mold Inhibitors to Paint: Mold inhibitors will prevent mold from forming on your walls. They can be added directly to housepaint.
  • Clean Bathrooms with Mold-Killing Products: Mold-killing products will reduce existing mold and keep mold from forming.
  • Remove Damp Materials from Your Home: Remove carpeting and upholstery that has been soaked and can’t be dried immediately. If your home becomes flooded, call in a specialist as soon as possible.
