21 August 2025
If you’ve ever planned a fresh paint job, you’ve probably asked the same question most homeowners do: how long will this take? The answer isn’t as simple as just “a few days” because every house, apartment, and project has its own variables. Weather, prep work, house size, and the number of painters involved can all shift the timeline.
In this guide, we’ll walk through the key factors that affect painting time, compare interior and exterior projects, and share real case studies from Australian homes. You’ll also see ballpark figures for different property types so you can plan with confidence.
Factors That Affect How Long Painting Takes
Every paint job is unique. Here are the main factors that influence how long your project might take:
1. Size and Layout of the Property
A compact two-bedroom unit will naturally take less time than a sprawling four-bedroom home with high ceilings. Layout matters too, lots of corners, trims, and awkward spaces require more detail.
2. Interior vs Exterior Surfaces
Interiors are usually faster since the work is indoors and less weather-dependent. Exteriors often require more preparation, washing, scraping, filling cracks, and sometimes scaffolding or ladders.
3. Preparation Work
Good painters know prep is half the job. Fixing cracks, sanding, patching holes, or priming bare surfaces can add hours or even days to the schedule. Skip the prep, and the paint may not last.
4. Number of Coats
Most walls need at least two coats, sometimes three for darker colours or dramatic colour changes. Exterior paints designed for harsh Aussie sun may also require extra layers for durability.
5. Access and Equipment
Single-storey homes are quicker than double-storey ones. If scaffolding, boom lifts, or extra safety equipment is needed, time goes up.
6. Weather Conditions
For exteriors, the weather is a big factor. Rain, humidity, or extreme heat can delay drying times. In Sydney, for example, summer humidity can push projects out by a few days.
7. Professional Painters vs DIY
Hiring professional painting services means more efficiency. A skilled crew can complete a job in half the time of a DIY effort. Plus, they know how to manage drying times, prep, and tricky surfaces.
How Long Does It Take to Paint a House Interior?
For interiors, the timeline depends on room numbers, ceiling height, and prep work.
1–2 Bedroom Apartment: 2–4 days
3 Bedroom House (single-storey): 4–7 days
4–5 Bedroom House (double-storey): 7–12 days
Case Study: Inner West Sydney Apartment
A two-bedroom apartment in Marrickville needed a quick turnaround before new tenants moved in. The painters:
- Patched small cracks and nail holes
- Applied two coats of low-VOC paint
- Painted ceilings, walls, and trims
Timeline: 3 full days
Outcome: The flat was fresh and ready for open inspection by the weekend.
How Long Does It Take to Paint a House Exterior?
Exterior projects are more variable because of weather, access, and prep.
Small Single-Storey Home: 5–7 days
Average Double-Storey Home: 8–14 days
Large or Heritage Home: 2–4 weeks
Case Study: Federation Home in Petersham
A heritage-listed Federation house had peeling weatherboards and sun damage. The painters:
- Stripped flaking paint
- Applied timber primer
- Painted in heritage-approved colours
Timeline: 3 weeks (due to weather delays and detail work on trims)
Outcome: The home’s charm was restored, boosting curb appeal significantly.
Combined Interior and Exterior Projects
If you’re painting both inside and out, expect the job to extend:
- 2 Bedroom Unit (interior + balcony exterior): 1–2 weeks
- 3 Bedroom House (inside and out): 2–3 weeks
- 4–5 Bedroom Double-Storey: 3–4+ weeks
This allows for drying times and careful staging, especially if you’re living in the house during the job.
These figures assume professional painters working standard 8-hour days with at least 2–3 painters on site.
Ballpark Figures by Property Type
Here’s a quick reference guide for how long painting usually takes in Australia.
| Property Type | Interior Only | Exterior Only | Interior + Exterior |
| 1-2 Bed Unit | 2-4 days | 3-5 days (balcony/trim only) | 1-2 weeks |
| 3 Bed House (single-storey) | 4-7 days | 5-7 days | 2-3 weeks |
| 4-5 Bed House (double-storey) | 7-12 days | 8-14 days | 3-4+ weeks |
| Heritage / Large Homes | 2-3 weeks | 2-4 weeks | 1-2 months |
Case Study: Rental Refresh in Western Sydney
A Mount Druitt landlord needed a budget-friendly paint refresh between tenants. The painters:
Focused on high-traffic areas (living, hallways)
Used washable low-sheen paint
Skipped ceilings and wardrobes to save time
Timeline: 4 days
Result: The property was leased within a week, proving that even partial repainting can have big returns.

- Speed and efficiency (teams can work simultaneously in different areas)

Final Thoughts
So, how long does it take to paint a house interior and exterior in Australia? The short answer: anywhere from 2-3 days for a small apartment to 1-2 months for a large heritage property. The long answer depends on all the factors we’ve explored, prep, size, access, weather, and finishes.
The key is planning ahead and hiring professional painting services that know how to get the job done right the first time. With the right team, you’ll enjoy a smoother process and a finish that truly transforms your home.
General Formula for Painting Turnaround Time
- Surface Area = ~250 m²
- Productivity Rate = 35 m²/day
- Number of Coats = 2
- Complexity Factor = 1.0
- Crew Size = 2 painters
- Prep/Weather Delay = 1 day
Turnaround Time = (250 ÷ 35 × 2 × 1.0) ÷ 2 + 1 = ~4 days
- Surface Area = ~500 m²
- Productivity Rate = 25 m²/day
- Number of Coats = 2
- Complexity Factor = 1.7 (ornate trims, scaffolding)
- Crew Size = 4 painters
- Prep/Weather Delay = 4 days
Turnaround Time = (500 ÷ 25 × 2 × 1.7) ÷ 4 + 4 ≈ 14–16 days
- Interior Surface Area = ~450 m²
- Exterior Surface Area = ~350 m²
- Productivity Rate = 30 m²/day (average across surfaces)
- Number of Coats = 2
- Complexity Factor = 1.2 (exterior prep + trims)
- Crew Size = 3 painters
- Prep/Weather Delay = 2 days
Turnaround Time = ((800 ÷ 30 × 2 × 1.2) ÷ 3) + 2 ≈ 12–13 days
General Formula for Painting Turnaround Time
Turnaround Time (days) = (Surface Area ÷ Productivity Rate × Number of Coats × Complexity Factor) ÷ Crew Size + Prep/Weather Delay
