Spray painting uses 10–20% more paint than brush and roller but saves 30–50% on labour time for large, open areas. For a full interior repaint, spray is often cheaper overall on new builds and empty houses. Brush and roller wins on occupied homes, detail work, and small jobs where masking time outweighs spray speed.

Build quotes faster →| Factor | Spray Painting | Brush & Roller |
|---|---|---|
| Speed (walls) | 3–5× faster | Standard rate |
| Material usage | 10–20% more paint | Standard coverage |
| Masking time | High (2–4 hours per room) | Low (30 min per room) |
| Finish quality (walls) | Very even, no roller marks | Slight texture (orange peel) |
| Finish quality (trim) | Excellent on doors/cabinetry | Good, brush marks possible |
| Cutting in | Still needs brush at edges | Brush for edges, roller for walls |
| Best for new builds | Yes - empty rooms, fast coverage | Adequate but slower |
| Best for occupied homes | No - too much masking required | Yes - targeted application |
| Equipment cost | $2,000–$8,000 (airless sprayer) | $50–$150 (brushes, rollers) |
| Overspray risk | High - needs careful masking | None |
| Touch-ups | Hard to match spray finish | Easy to touch up with brush |

Here's how the total cost compares on common NZ painting jobs:
| Method | Labour Days | Materials | Total |
|---|---|---|---|
| Spray | 3–4 days | $1,200–$1,800 | $4,000–$6,500 |
| Brush/roller | 5–7 days | $1,000–$1,500 | $5,500–$8,500 |
| Method | Labour Days | Materials | Total |
|---|---|---|---|
| Spray (with masking) | 5–7 days | $1,400–$2,000 | $5,500–$8,500 |
| Brush/roller | 5–7 days | $1,000–$1,500 | $5,500–$8,000 |
In an occupied home, the cost is nearly identical because masking time offsets spray speed. In an empty house, spray saves 15–25% overall.

It depends on the job. Spray painting saves 15–25% on empty houses and large exteriors where masking time is minimal. On occupied homes, the extensive masking needed makes spray and brush/roller roughly the same total cost.
Yes - spray application uses 10–20% more paint than brush and roller due to overspray and the atomisation process. On a full house interior, that's an extra $100–$300 in paint. The labour savings on suitable jobs more than offset this.
Spray produces a smoother, more even finish on large flat surfaces like walls, ceilings, and doors. Brush and roller leaves a slight texture (orange peel) that some homeowners actually prefer. For trim and cabinetry, spray gives a factory-quality result that's hard to match with a brush.
