How to treat mold on concrete walls in Dubai?« Back to Previous Page

Concrete walls in Dubai's humid climate are prone to mold due to condensation, especially in enclosed spaces like wardrobes with poor air circulation. The first step is to identify and address the moisture source—it's often a small, hidden plumbing leak or condensation from an AC duct running inside the wall cavity.

For treatment, start by scrubbing the area with a solution of white vinegar or a dedicated mold remover. Wear an N95 mask and gloves. After cleaning, let the wall dry completely; a dehumidifier or fan is essential for this. Do not just paint over it, as the mold will return.

However, if the mold has penetrated the porous concrete or covers an area larger than one square meter, a surface clean is insufficient. The hidden moisture problem must be professionally diagnosed to prevent rapid regrowth. In such cases, a certified inspection can identify the exact species and moisture source, which is critical for a permanent solution. For villas, this often involves thermal imaging to find cold spots and condensation points.

To prevent recurrence, ensure the room's AC is consistently running to control humidity and improve air circulation in the wardrobe—leave the door ajar or install ventilation grilles. In many Jumeirah villas, this is a recurring issue without addressing the underlying humidity and airflow.
