How to properly repair peeling interior wall paint from dampness?« Back to Previous Page

Based on the symptoms you describe in Al Barsha, this is almost certainly moisture intrusion, not just a simple paint issue. The heavy dew is a major clue; high ambient humidity condenses on cooler surfaces, and if there's a slight breach in your exterior wall's vapor barrier or waterproofing, that moisture is being driven inside.

The proper diagnostic steps are critical. First, a non-invasive moisture meter is used to map the exact moisture content within the wall and identify the wet spots' core. Then, a thermographic (infrared) camera is essential to visually trace the moisture path and temperature differentials, which often reveals the exact entry point from the outside. We must also check for compliance with the Dubai Green Building Regulations, which specify required waterproofing standards for villas.

Repair is a multi-stage process. 1) The root cause—the exterior leak—MUST be identified and sealed by a certified waterproofing specialist. 2) Internally, all affected plaster and paint is removed back to a sound substrate. 3) The wall must be thoroughly dried using industrial dehumidifiers, which we measure with a thermo-hygrometer to confirm dryness. 4) Only then can new plaster and a moisture-resistant primer be applied before repainting.

Given the prevalence of this issue in UAE villas, a professional inspection is strongly advised to prevent structural damage and mold growth. Attempting a DIY fix will almost certainly fail and cost more long-term. For a certified assessment, please call our experts at 800-MOLDS or email hello@saniservice.com.
