How to permanently stop mold on my living room wall?« Back to Previous Page

The black spots returning after cleaning indicate an ongoing moisture source. In Dubai's ground-floor apartments, this is often external humidity seeping through the wall or condensation from temperature differences.

First, identify the moisture source. For external walls in Jumeirah, the most common cause is penetrating damp from high humidity, especially after fog. The permanent solution requires fixing this entry point. A professional inspection can pinpoint if it's a crack in the wall, faulty sealant, or inadequate waterproofing—this is a critical first step for a lasting repair.

Until the leak is sealed, cleaning is temporary. For small areas, a solution of diluted detergent (not just vinegar) can remove surface growth, but it will return without addressing the dampness.

Long-term, the wall likely needs proper waterproofing from the exterior, which may require building management coordination, as it's a structural issue. Internally, improving air circulation around that wall is vital. Ensure your AC is running consistently to manage indoor humidity, and consider using a dehumidifier during the most humid winter months. Repainting with an anti-mold additive paint can provide a temporary barrier, but only after the moisture issue is fully resolved.
