Why cracks appear in Dubai
Temperature swings — outside +45C, inside +20C from AC. New building settlement — normal process for the first 3-5 years. Hard water damages plaster from within. Vibration from nearby construction.
Safe cracks — no urgent action needed
Hairline cracks (under 0.5mm) in plaster or filler. Cracks at window and door corners — classic settlement. Horizontal cracks at ceiling-wall junctions.
Dangerous cracks — call a specialist
- Width over 3mm and still growing
- Diagonal cracks running from opening corners
- Through-cracks across the full wall
- Cracks with material delamination
How to repair cracks yourself
Hairline cracks: open with a grinder, prime, fill with acrylic sealant or filler. Cracks 1-3mm: reinforcing mesh plus finish plaster. Over 3mm — call a specialist.
