How to remove black mold and prevent dampness?« Back to Previous Page

Black mold behind furniture on an exterior wall in Dubai is a common issue, particularly in high-humidity coastal areas like Marina. The dampness is likely due to condensation forming on the cooler wall surface, a frequent problem when AC units are set to very low temperatures in our climate.

For the existing growth, do not attempt to remove it yourself with bleach or by scrubbing, as this can aerosolize harmful spores. Isolate the area and consider the wall material. For non-porous surfaces like painted concrete, a solution of diluted detergent can be carefully applied to dampen and wipe the mold away, but wearing an N95 mask and gloves is essential. For drywall or porous materials, professional remediation is strongly advised to safely remove contaminated sections.

Preventing its return requires addressing the condensation. First, ensure your AC unit is serviced and draining properly; a clogged drain line will raise indoor humidity. Keep the AC running consistently, even when absent, to maintain stable temperature and dehumidification. Increase air circulation behind the dresser by moving it a few inches away from the wall. For a more permanent solution, inspect the exterior wall for cracks or failed sealant that may be allowing humid air to infiltrate. Applying a mold-resistant paint or coating after the area is completely dry and remediated can provide a protective barrier.

Given the symptoms your children are experiencing, a professional inspection is recommended to identify the specific mold species and the full extent of the moisture issue, as hidden growth within walls is possible. They can perform a humidity assessment to pinpoint the condensation source and verify the remediation was successful.
