For exterior work, October to April. Painting a sun-facing elevation in peak summer means the coating skins before it can level, which shows as roller marks, poor adhesion and early failure.
Interior painting runs year-round, because the AC controls both temperature and humidity. The constraint indoors is ventilation and recoat timing, not the season.
Humidity matters as much as heat. Coating a surface that has not fully dried after washing traps moisture underneath, and that is a common cause of blistering on balconies and parapets.
Respect the recoat interval on the tin. Applying a second coat early looks efficient and produces a soft film that marks as soon as it is wiped, which is a repaint rather than a touch-up.
Schedule around handover dates with slack. Paint needs curing time, and an inspection booked for the morning after the last coat is how snag lists get written.
