March to May: the pre-summer sprint and heat-reflective coatings
Spring is when smart villa owners do the work that pays off in their DEWA or ADDC bill. Heat-reflective exterior paints — sold in the UAE under names like Jotun Jotashield Extreme and equivalent National Paints and Caparol lines — use infrared-reflective pigments to bounce a meaningful share of solar heat off the wall before it soaks into the block. Applied to a west- or south-facing villa elevation before June, they measurably lower the heat load the AC has to fight all summer. Applied in September, you have paid for the benefit and missed the season it matters most.
The pre-summer window is also when exterior crack repair should happen. Hairline cracks in render open and close with thermal movement; summer expansion makes them worst, and painting over an open crack in May with a standard emulsion guarantees it reappears by August. Elastomeric coatings, which stretch with the substrate, cost more per square metre but are the honest fix for a crack-prone elevation.
