How Long Does Interior Painting Take? Full Timeline Guide (2026)
Planning an interior repaint in 2026? One of the first questions London homeowners ask is: “How long will the painting process take?”
This guide from PaintingServices.London LTD breaks down realistic timelines for different room types, including preparation, drying time, and the key factors that speed up or slow down a project.
Average timelines for interior painting projects
Painting duration varies depending on room size, preparation needs and materials, but here are typical 2025 estimates for London properties:
- Small bedroom (10–12 m²): 1 day
- Medium bedroom (12–18 m²): 1–2 days
- Large bedroom/master room: 2 days
- Living room: 2–3 days
- Hallway/stairs/landing: 2–4 days (more prep & cutting-in)
- Kitchen: 1–2 days
- Full flat/house repaint: 3–10 days depending on size & scope
What affects how long interior painting takes?
Every property is different. Here are the main factors that influence timelines:
1. Preparation requirements
Prep is 60–70% of the job. Filling cracks, sanding, priming repairs and masking surfaces all add time but ensure a long-lasting finish.
2. Number of coats
Most rooms require two finish coats plus a primer on any bare or repaired areas.
3. Drying time
Modern low-VOC paints dry quickly, but London humidity can extend the process. Typical drying time is 2–4 hours per coat.
4. Access and furniture
Rooms with heavy furniture or limited space take longer to prepare and move around.
5. Condition of existing surfaces
Stains, damp areas, flaking paint or previously uneven work require extra steps, such as stain blocking or deeper sanding.
Timeline example: standard bedroom repaint
Here’s what a typical 1–day bedroom project looks like:
- 08:00 – Protection: Floors covered, furniture moved & masked.
- 08:30 – Preparation: Filling cracks, sanding, spot-priming.
- 10:00 – Cutting-in & first coat: Walls and ceiling.
- 12:30 – Break/drying time.
- 13:00 – Second coat: Final coverage.
- 15:00 – Woodwork touch-ups: Skirting, frames, doors.
- 16:00 – Cleanup & walk-through.
How to speed up the painting process
- Clear as much furniture as possible before painters arrive
- Ensure rooms are well-ventilated for faster drying
- Choose quick-drying, low-odour paints
- Discuss colour choices in advance to avoid delays
