The Step-by-Step Guide to Removing Mold from Walls (Painted)

Removing mold from painted walls can be more challenging than tiled walls. Here’s the process that can guarantee you a safe removal if you follow it carefully.

Identify the type of mold

While most household molds are harmless, some, like black mold (Stachybotrys chartarum), can be toxic. If you're unsure about the type of mold you're dealing with, it's best to consult a professional. However, for most common mold types, you can safely proceed with the following steps.

Assess the Situation 

This can be done with the above step but what you have to do is determine the extent of the mold growth and whether the drywall has been compromised. If the mold growth covers a large area (more than 10 square feet) or if you have health concerns, consider hiring a professional for mold remediation. 

For the drywall, check if it is soft, crumbling, or warped, it might need to be replaced if it meets any of the criteria. 

For smaller areas and surface mold on intact drywall, you can typically handle the removal of mold from walls yourself and follow the rest of the steps.

Prepare the Area and Gear Up

Because you will be working with cleaning agents and chemicals, you’ll need to protect yourself, the flooring, and the surrounding area. To prevent mold spores from spreading during cleaning, isolate the affected area by closing doors and windows.

Wear gloves, goggles, and a mask to protect yourself. Cover the floor and nearby furniture with plastic sheeting. If possible, open a window or use an air scrubber to help ventilate the area and remove airborne mold spores.

Select Your Cleaning Solution

For minor mold growth, a solution of warm water and dish soap may be sufficient. But for tougher stains or larger areas, consider using a vinegar solution (equal parts water and white vinegar). This is effective on how to remove mold from painted walls with vinegar.

Alternatively, a diluted bleach solution (1 part bleach to 3 parts water) can be used. Remember that bleach can discolor painted surfaces, so be sure to test it on an obvious area first. Depending on your preference, you can also purchase a commercial mold remover.

Apply the Cleaning Solution

Spray or apply the cleaning solution to the affected area and let it sit for 10-15 minutes. You can apply the solution using a sponge or a brush. This will help kill the mold and loosen it from the surface.

Deep Clean and Disinfect

After removing mold from the painted wall, wipe down the entire area with a disinfectant cleaner to kill any remaining spores. Let the surface dry completely. To prevent future mold growth, consider using a dehumidifier to maintain lower humidity levels in the room.

Prevent Future Mold Growth 

To prevent mold from returning, address the source of moisture. Fix any leaks, improve ventilation, and use a dehumidifier if necessary. Regularly inspect your walls for signs of moisture or mold growth, and clean them promptly if needed. A HEPA air scrubber can also help filter mold spores from the air and prevent future growth.

Additional Tips for How to Clean Mold Off Walls

Test cleaning solutions: Always test your cleaning solution on an inconspicuous area i.e. obvious spots first to make sure it does not damage the paint.

Work in sections: If you have a large area of mold, work in sections to prevent the cleaning solution from drying out before you have a chance to scrub it.

Don't mix bleach and ammonia: Mixing bleach and ammonia can create toxic fumes so exercise caution when handling your cleaning solutions.

Discard cleaning materials: After you're done, discard any cleaning materials that came into contact with mold to prevent recurrence. 

By following these steps and tips, you can effectively remove mold from your painted walls and prevent it from returning, ensuring a healthier and more comfortable home environment.

In Conclusion

According to the U.S. Environmental Protection Agency (EPA), there is no way to eliminate all mold and mold spores indoors. The key to mold control is controlling indoor moisture.
