Repainting is 25–40% cheaper than fresh painting. Fresh painting costs ₹18–35/sq ft because it includes full putty work (2 coats), primer, and paint. Repainting costs ₹12–25/sq ft because the putty base already exists — only touch-up, primer, and paint are needed. Repainting is suitable when walls are in good condition with only fading or minor wear.
