<p>In Indian conditions, a good quality exterior system typically lasts five to seven years, sometimes longer on shaded elevations. Darker shades tend to absorb more heat and may fade faster, especially on west-facing walls. Lighter tones stay cooler and can look fresh for longer, particularly when combined with durable primers and topcoats. Surface preparation, including cleaning, repairs, and proper priming, is just as important as the shade itself. If you live in a coastal or highly polluted area, discuss extra protective layers and specialised coatings with your painter for better performance.</p>
