In spite of all your efforts to maintain your home clean and dry, it is really surprising to see moldy areas such as on your ceiling and walls. Most affected areas include bathrooms, laundry rooms, and kitchens where water is commonly used. Mold usually loves to thrive in warm, moist environments and if neglected, it will promote future mold growth. In addition, mold spores are easily spread through the air and contribute to several respiratory issues and allergic reactions.

“How to get rid of mold on walls?”. This is often asked by many homeowners who would want to remove minor mold issues on their own. And this will give them ideas on how to prevent damage to the structural integrity of their homes and preserve their health. For major mold issues, it is best to consult mold professionals.

Spot the Signs of Mold on Your Walls

Detecting the presence of mold in your home earlier will save you from a bigger mess. However, if mold has badly affected your home, hiring a mold remediation team is necessary. Inspect and check your property for water damage. Then, look for these signs;

  • Cracked/ peeling/sagging paint
  • Discoloration
  • Recurrent mold stains like black dots, streaks, or specks
  • Bulging
  • A musty, damp odor

A Few Safety Reminders

Removing molds from your walls in whichever way you choose, safety must always be on top of your priority. A few tips include:

  • Using masks, rubber gloves, and goggles.
  • Keeping the environment well-ventilated. Open windows and doors to prevent the gases from the products’ chemical reactions with spores from poisoning anyone.
  • Testing the substance first on a small piece of the wall before applying it to the entire surface. This allows you to see if the chemical will damage the paint.


Mold Technique for Each Type of Wall

Each type of wall has a slightly different technique for mold removal: 

1. Wallpaper

  1. The best solutions that will work for mold on the wallpaper are white vinegar, tea tree oil, or grapefruit seed extract.
  2. Dip a sponge in the solution, squeeze, and test a part of the moldy area. This will avoid damaging the wallpaper. 
  3. Rub gently in circles to get rid of mold. Then, clean it with warm water.
  4. Avoid soaking the wallpaper.

 2. Drywall

  1. Though you can see surface mold only on the drywall, it has most likely threaded its way below the surface since the drywall is porous. In this case, avoid using bleach in porous materials because the chlorine will just stay on the surface. Furthermore, the water in bleach solutions will just sink in and can lead to mold growing again.
  2. Try using a vinegar solution. Acidic or alkaline cleaning products that get absorbed are more effective.
  3. Pour full-strength vinegar into a spray bottle and directly apply to growing molds on walls.
  4. Leave vinegar for two hours then scrub the area with a stiff-bristled brush.
  5. You can use this in black mold or any type of mold.
  6. If the mold returns and it’s deeply rooted, consider replacing the drywall. Fortunately, mold-resistant drywall is now available.

3. Cinder Blocks

  1. You must clean the wall first then apply the cleaning solution.
  2. Wipe away mold residue.
  3. Apply more solution and let it sit for up to 20 minutes.
  4. Make sure to completely dry the wall. 

 4. Concrete

  1. Both concrete and brick are porous. So either vinegar or hydrogen peroxide is the best solution to kill molds even at the roots.
  2. Use a brush to scrub and make sure to clean all of the molds.
