Paint answers to the weather here
Humidity is the other half of the equation. On the Gulf coast in August, relative humidity regularly climbs past 80 per cent overnight. Water-based paint cures by evaporation, and evaporation slows to a crawl in saturated air, so recoat times stretch and soft films pick up dust and fingerprints. Trapped moisture is also the main cause of the blistering you see on older buildings near the sea — bubbles under the film where vapour pushed its way out.
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.
