Paint is the last coat and the first thing anyone sees. Good results depend almost entirely on the wall underneath and on patience.
Interior Sequence
| Step | Purpose |
|---|---|
| Surface preparation | Remove dust, loose material |
| Crack filling | Fill fine shrinkage cracks |
| Wall putty (1–2 coats) | Smooth surface |
| Sanding | Even finish |
| Primer | Bond and uniform absorption |
| Emulsion (2 coats) | Finish |
Exterior Sequence
| Step | Purpose |
|---|---|
| Check for cracks and leaks | Water behind paint causes failure |
| Exterior primer | Bond, alkali resistance |
| Exterior emulsion (2 coats) | Weather and UV protection |
Lighter exterior colours absorb less heat — useful on west- and south-facing walls in Hyderabad.
Common Problems
| Problem | Cause |
|---|---|
| Peeling | Damp wall, no primer, dusty surface |
| White salt patches (efflorescence) | Moisture carrying salts out of masonry |
| Patchy finish | Uneven absorption — primer skipped |
| Cracks reappearing | Junction cracks without mesh |
The Short Version
Dry plaster, filled cracks, putty, primer, two finish coats — and fix any dampness first. Paint only performs as well as the wall it sits on.
