Identify the cause of the humidity
Before cleaning everything, the first step is to understand why mold appears. If your wall is constantly damp, there may be a leak or leak somewhere in your home. Stay tuned! If the cause is not treated, the mold can return violently. In the simplest cases, such as lack of ventilation, a good solution is to make the room more airy by opening windows or using a dehumidifier. If you find any leaks, you will need to call a professional to fix the problem and avoid further damage to the structure of your home.
Use homemade products
If the mold is not present in large quantities, the good news is that you can use products that you probably already have at home. One of the best allies against mold is white vinegar, which has natural antibacterial properties and fights mold without strong odors. To use it it is simple: just take a cloth or sponge and apply the vinegar directly to the affected areas. Leave it on for about an hour and then use a damp cloth to remove it. Another powerful product is baking soda, which also has antibacterial and antifungal effects. Simply make a paste with water and apply it to the mold stains. Leave to act for a few minutes and scrub with a brush. If mold persists, chlorine or bleach may be helpful, especially for stubborn stains, but use with caution and never pure!

Specific Products for Molds
If mold has already invaded your wall or is very resistant, it may be time to invest in a specific product to eliminate it. The market offers a wide variety of antifungal products specifically designed to fight mold and they tend to be much more effective in more severe cases. These products, in addition to eliminating mold, also help prevent its reappearance. During use, remember to follow the manufacturer’s instructions, always with attention and protection, such as the use of gloves and ventilation of the environment. These products can be found in building materials stores or supermarkets and the application is usually very simple.
Do the cleaning
Now that you’ve chosen the right product, it’s time to take action. Take a sponge or cloth and pass it directly over the affected area. For more resistant mold it is important to scrub well, using a brush if necessary. Remember to always wear rubber gloves, because mold can be harmful to your health, as well as staining the skin. And of course, after cleaning, it is essential to rinse the wall well with clean water. If the mold persists, repeat the operation until the wall is completely clean.
Let it dry well
Once you’re done cleaning, the key to preventing mold from returning is to make sure the area is completely dry. Mold loves humid environments, so it’s important to leave the space well ventilated. Open doors and windows, turn on a fan or, if possible, use a dehumidifier. Proper ventilation helps it dry faster and prevents mold from returning. In more humid environments, such as bathrooms, it is important to always keep the area dry and ventilated.
Prevent return
Now that the wall is clean and dry, the next step is to make sure the mold doesn’t return! To do this, a good idea is to apply anti-mold paint on the walls, especially in the areas most sensitive to humidity, such as bathrooms and kitchens. Furthermore, if the mold problem is recurring, you can invest in waterproofing the walls. But it is not enough to just take care of the walls, it is necessary that the environment as a whole is well ventilated. If necessary, use dehumidifiers and avoid leaving wet clothes or towels piled up. This daily care will ensure your home stays mold-free and healthier!

Adequate ventilation
Keeping rooms well ventilated is the first measure to combat humidity and prevent mold. Open windows when possible and use exhaust fans in humid areas, such as bathrooms and laundry rooms. The airflow helps dry moisture from the walls.
Use of dehumidifiers
In more humid environments, such as basements or areas with poor ventilation, the use of dehumidifiers can be an effective solution to reduce humidity in the air and avoid the formation of mold on the walls.
Repairs to leaks
Infiltration is one of the main causes of mould. Check for leaks on the walls, ceiling or windows and make any necessary repairs to prevent water from pooling and encouraging mold growth.
Avoid excess humidity
Avoid activities that can generate excessive humidity, such as hanging clothes indoors, especially on rainy days. If possible, use clothes dryers or dry clothes outdoors.
Anti-mofo paint
A preventative option is to paint the walls with anti-mold paints, formulated to fight humidity and prevent the appearance of fungi and mold. These paints help create a layer of protection, making the walls more resistant to moisture.
Constant maintenance
In addition to keeping ventilation up to date and controlling humidity, carry out periodic maintenance on walls and interior spaces to detect signs of mold or infiltration. The faster the problem is identified, the easier it will be to control it.
