Paint answers to the weather here
Paint is chemistry, and chemistry cares about temperature and moisture. Most emulsion paints sold in the UAE are formulated to be applied between roughly 10 and 35 degrees on a surface that is dry and stable. For half the year, an exterior wall in Dubai or Abu Dhabi sits well outside that range by mid-morning — a west-facing villa wall in July can reach 60 degrees or more at the surface, hot enough to flash-dry emulsion before it can level out. The result is visible lap marks, poor adhesion and a coat that starts failing within a couple of years instead of lasting five or six.
None of this means painting stops in summer. It means the work moves indoors, the schedule changes, and good crews adjust their methods. The rest of this guide is organised the way experienced UAE painters actually think: around the calendar.
