How Much Paint Do You Need?
The coverage of 20 litres of emulsion paint depends on several factors:
- Surface texture (smooth vs. rough)
- Type of emulsion (standard, premium, or textured)
- Number of coats
- Application method (brush, roller, spray)
General Coverage Estimate
| Surface Type | Coverage (per coat) | Coverage with 20L (1 coat) |
|---|---|---|
| Smooth surface | 10–12 m² per litre | 200–240 m² |
| Semi-rough surface | 7–9 m² per litre | 140–180 m² |
| Rough surface | 5–7 m² per litre | 100–140 m² |
Note: These are estimates for one coat. Most emulsion paint jobs require two coats, so divide the total area by 2 for full coverage.
Example Calculation
- You have a smooth wall and plan to apply 2 coats.
- Area to paint: 120 m²
- Coverage: ~10 m² per litre
- Total paint required: (120 m² × 2 coats) ÷ 10 m²/L = 24 litres
- So, 20L will cover about 100–120 m² with two coats on a smooth wall.
Tips for Maximizing Coverage
- Proper surface preparation (smooth, clean walls)
- Use of primer to reduce paint absorption
- Apply with a roller for even spreading
- Avoid painting in high humidity (can affect drying and coverage)
