How to permanently stop mold from AC leak in Dubai?« Back to Previous Page

The black spots and musty smell indicate active mold growth, which is common here after an AC leak, especially during humid periods. The first step is to stop the moisture source. You must have the AC unit's drain line and drip pan professionally serviced to fix the leak permanently.

For the existing mold, simply wiping it or painting over it will not work and can spread spores. The wall cavity behind the wardrobe likely has significant growth that needs proper remediation. This involves isolating the area, physically removing contaminated porous materials like drywall or insulation, and HEPA-vacuuming all surfaces. For a case this advanced, a professional inspection is strongly advised to assess the full extent.

After remediation, the area must be completely dry before any repainting. Use a dehumidifier and fans for at least 48-72 hours to ensure the wall's internal moisture levels are below 16%. Then, apply a dedicated mold-inhibiting primer—look for products labeled as EPA-registered or containing antimicrobial agents—before repainting with a high-quality, moisture-resistant paint.

To prevent recurrence, maintain indoor humidity below 60% using a dehumidifier or your AC's dry mode. Ensure your AC unit receives bi-annual maintenance to prevent future condensate leaks, which are a primary cause of mold in Dubai homes. The key is addressing the root cause (the leak), not just the visible symptoms.
