Damp seasons often bring an unwelcome guest into our homes: moldy, cracked, or peeling walls. Not only are they unpleasant to look at, but they can also affect the air quality and damage the structure of your walls over time. Fortunately, you can handle many of these problems yourself, easily and inexpensively.

Here are a few simple, budget-friendly methods to clean and protect your walls from mold and peeling paint.

🧽 1. Dry Brushing Method

During humid months, walls often develop small mold patches. The first thing you should do is use a dry brush to gently scrub off the visible mold on the surface.

After brushing, dip a soft cloth in a small amount of alcohol or disinfectant, then wipe the affected area to prevent mold spores from regrowing. This method works best when mold is newly formed and localized, before it spreads across a large surface.

Tip: For a light mold problem, natural cleaning agents like vinegar or lemon juice can also be effective. Spray them onto the surface, let sit for 10–15 minutes, then wipe clean.

🧴 2. Cleaning with Bleach Solution

If the mold has spread more noticeably, try using household bleach. Mix bleach with water at a 1:99 ratio, then pour the mixture into a spray bottle. Spray it directly on the moldy area and leave it for a few minutes to let the bleach work.

Next, use a soft brush to scrub gently and wipe with a clean cloth.
For more severe mold, you can increase the bleach concentration to 1:20.

However, keep in mind that this method is mainly effective for surface-level mold. If your walls are heavily affected, you’ll need a more thorough treatment—such as sanding the wall, applying an anti-moisture primer, and then repainting.

Safety note: Always wear gloves and ensure good ventilation when working with bleach or other strong cleaning agents.

🧱 3. Fixing Peeling or Bubbling Paint

When paint starts to peel or bubble, it’s often because of trapped moisture behind the wall. To fix this:

1. Scrape off all the loose and peeling paint using a putty knife or scraper.

2. Sand the surface with sandpaper until smooth and even.

3. Apply a coat of primer or waterproof base paint.

4. Once it’s dry, finish with a fresh coat of paint.

If the damaged area is large, wait until the wall is completely dry before repainting. Pay special attention to the bottom section of the wall, as this area is most prone to moisture. You can also fill small cracks with wall putty or plaster before painting.

Avoid repainting during the rainy season, as the high humidity will prevent the paint from bonding properly.

🧩 4. Quick Fixes for Cosmetic Improvement

If you don’t have the time or budget for a full repair, you can temporarily cover the damaged spots with wallpaper, PVC panels, or foam wall stickers.

Before applying, be sure to remove any loose paint or mold and clean the surface thoroughly. While this won’t solve the root cause of the moisture, it will improve the room’s appearance quickly and affordably.

🌬️ 5. Preventing Dampness and Mold in the Future

Once you’ve cleaned your walls, it’s important to keep them dry to prevent mold from returning. Here are a few preventive tips:

• Use a dehumidifier: It’s the most effective way to maintain proper humidity indoors.

• Try natural moisture absorbers: Charcoal, quicklime, or silica gel packets can help absorb excess moisture in corners, closets, or behind furniture.

• Keep windows closed during humid days: When the air outside is moist, keeping doors and windows shut prevents “sweating walls.”

• Air out your house on dry days: Let fresh air circulate to reduce trapped humidity.

• Use your air conditioner’s dehumidify mode: Running it for 2–3 hours can significantly lower indoor moisture levels.
