How to permanently fix mold under UAE shower sealant?« Back to Previous Page

The mold under your silicone sealant is a common issue in Dubai bathrooms due to high humidity and condensation. To fix it permanently, you need to address both the existing growth and the moisture source.

First, the contaminated sealant must be completely removed with a sharp utility knife or scraper. Any remaining mold on the tile or grout beneath should be scrubbed with a dedicated mold cleaner, not just bleach, which often only bleaches the surface. Thoroughly dry the area with a fan for at least 24 hours before reapplying anything.

For a lasting solution, use a high-quality, 100% silicone sealant specifically labeled as mold and mildew resistant. These contain biocides that help inhibit growth. In the UAE's climate, ensuring the bathroom is properly ventilated is critical. Running the exhaust fan during and for at least 30-45 minutes after a shower is essential to remove humid air. If humidity still lingers for hours, your fan may be underpowered or improperly vented, which is a common finding in apartments.

If the mold growth is extensive, has penetrated deeply behind the tiles, or if you or family members experience respiratory issues, a professional inspection is recommended to assess the full scope. They can perform moisture mapping to identify any hidden dampness and verify that the remediation is complete.
