1. How Long It Takes to Paint a Single Room
The most useful published UK timings come from Which?'s painter and decorator cost survey, which asked Which? Trusted Traders how long common jobs take. For repainting walls and ceilings in two coats of light emulsion, with plaster in good condition, it reported:
Small room (about 2.1m by 2.2m): 1 to 2 days
Medium room (about 3.3m by 3m): around 2 days
Large room (about 6.1m by 5m): 2 to 3 days
These are guides. Your room may take more or less time depending on its condition, the number of coats and how much woodwork is included. A lot of the time is spent waiting for coats to dry, which is why even a small room can spread over two days.
2. Hallways, Stairs and Landings
Hallways look small but take a long time because of the height over the stairs, the number of doors and the awkward access. Which? estimates about 3 days to repaint the walls only in the hall, landing and stairs of a typical three-bedroom house. Add more if woodwork, spindles or ceilings are included.
Safe access over the stairwell is essential. Decorators use platforms or stair ladders designed for the job, and the HSE's work at height guidance explains why proper equipment matters.
3. Wallpapering Timescales
Which? estimates about 3 days to line and paper a room of around 4.4m by 3.3m, assuming sound walls and no old paper to remove. Stripping existing paper, repairing plaster or hanging complex patterns will add time. A single feature wall can often be done in a day.
4. Painting a Whole House Interior
A full interior repaint is essentially the sum of its rooms, but there are efficiencies: the decorator sets up once, buys materials in bulk and can paint one room while another dries. As a rough guide, a solo decorator might take one to two weeks or more for a typical family home, depending on size and scope. That's our estimate from the room timings above, not a published figure, and a team can finish faster. Ask each decorator for their own estimate for your home.
Quick tip: ask decorators how many people will work on your job. A two-person team can halve the time on site, which matters if you're living in the house.
5. Painting a House Exterior
Exterior jobs depend heavily on access and weather. Erecting scaffolding, washing down, repairing render and allowing drying time between coats all take time, and rain can stop work completely. Ask decorators for an estimated number of working days and how they handle weather delays. Booking in late spring or summer gives the best chance of dry spells.
6. What Slows a Decorating Job Down
Poor wall condition: cracks, blown plaster and old paper all add preparation time.
Colour changes: going from dark to light may need extra coats.
Furniture: a full room takes longer to protect and work around.
Drying conditions: cold, damp rooms slow drying between coats.
Woodwork: skirting, doors and frames need multiple coats with drying in between.
Changes midway: adding rooms or changing colours after work starts.
7. How to Keep Your Project on Schedule
Choose colours and finishes before work starts.
Clear rooms and remove fittings in advance. See our checklist for preparing your home for a decorator.
Agree the order of rooms and a realistic timescale in writing.
Keep rooms ventilated and reasonably warm to help paint dry.
Make sure the decorator has parking and access each day.
When comparing quotes, include the estimated duration in your comparison. Our guide on comparing decorating quotes explains how. For general tips on choosing someone reliable, read how to find a painter and decorator.
Frequently Asked Questions
Can I use a room the same day it's painted?
Often you can use it lightly once the paint is touch-dry, but walls stay delicate for a while. Avoid hanging pictures or pushing furniture against fresh paint, and follow the paint manufacturer's guidance on curing.
How long should I wait between coats?
It depends on the paint and the conditions. Most emulsions and many water-based woodwork paints state a recoat time on the tin. Your decorator will plan around this.
Is it quicker to spray than roll?
Spraying can be faster on large, empty areas, but masking takes time and it isn't suitable everywhere. Ask whether your decorator sprays and when they'd recommend it.
Why does my decorator need two days for one room?
Mainly drying time. Filling and sanding come first, then each coat needs to dry before the next. A second visit often gives a better finish than rushing.
Should I move out while the house is decorated?
Most people stay at home during interior decorating, especially if the work is done room by room. For a whole-house repaint, it can help to plan which rooms you'll live in each day, keep a clear route through the house and ventilate well. Low-odour water-based paints make living with the work easier.
How long does exterior paint need before rain?
It depends on the product, the temperature and humidity. Many masonry paints state a minimum dry period before exposure to rain on the tin. Decorators watch the forecast closely and may delay a coat if rain is due.
Does a mist coat add time?
Yes. On new plaster, the mist coat is an extra coat that needs to dry before the finish coats, so expect new-plaster rooms to take a little longer than a simple repaint.
How Find A Decorator Can Help
Find A Decorator is a new UK marketplace that connects homeowners and businesses with professional painters and decorators. We're in our early, pre-launch stage, so we're still growing our network of decorators in each area. Decorator profiles cover 11 regions across Great Britain: Greater London, the South East, South West, East of England, West Midlands, East Midlands, North West, North East, Yorkshire & the Humber, Scotland and Wales. We don't cover Northern Ireland at the moment.
To get started, post your decorating job with as much detail as you can: room sizes, surfaces, photos and when you'd like the work done. You can read more about our interior painting service, and if you have questions about how the platform works, our help centre explains the process step by step.
A clear job description gets more accurate quotes. Include the number and approximate size of the rooms or areas, which surfaces need painting, the current condition of walls and woodwork, whether you'll supply the paint, any access issues such as parking or stairs, and your ideal start date. The more a decorator knows up front, the fewer surprises there are later for both of you.
Final Thoughts
Which?'s data suggests one to three days for most single rooms, around three days for a hall, stairs and landing, and about three days to wallpaper a room. Preparation, drying time, access and the weather drive the timescale far more than the painting itself. Ask each decorator for an estimated number of days, agree the order of rooms in advance, and plan family life, deliveries and any house move around a realistic schedule rather than the fastest possible one.
