How Long Does It Take to Paint a Room?

Quick answer

For one decorator working on a single average-sized room, walls, ceiling, and woodwork, two coats throughout:

• Small bedroom or box room: 1 day
• Double bedroom or home office: 1–2 days
• Living room (average size): 2–3 days
• Large or open-plan room, high ceilings: 3–4 days
• Whole 3-bed house, interior: 2–3 weeks

These are working-day figures, not calendar days — they assume the room is accessible and empty enough to work in from the start.

Where the time actually goes

A lot of people picture painting as mostly rolling colour onto a wall. In practice, that’s roughly a third of the job. A realistic breakdown for a single room:

1. Protection and setup (30–60 minutes) — dust sheets down, furniture moved or covered, masking tape along edges, sockets and fittings covered.
2. Preparation (a few hours to most of a day, depending on condition) — filling cracks and holes, sanding filler smooth, sanding back any flaking or glossy woodwork so new paint keys to it, washing down greasy areas (kitchens especially), and spot-priming bare patches or stains.
3. First coat (a few hours) — walls, then ceiling if it’s being done, then woodwork. Cutting in by hand around edges takes longer than rolling the open wall.
4. Drying time between coats — most trade emulsions need 2–4 hours before recoating; gloss and satinwood on woodwork often need longer, sometimes overnight for a hard-wearing finish. This is the step that catches people out when they’re doing it themselves on a tight weekend — rushing a second coat over a tacky first coat is one of the most common causes of a patchy finish.
5. Second coat (a few hours) — same order as the first, usually faster since less cutting-in precision is needed once the base colour is down.
6. Snagging and cleanup — checking edges and corners in daylight, touching up any thin patches, removing tape cleanly, folding sheets away.

What makes it take longer

• A colour change, especially dark-to-light or the reverse, which can mean a mist coat or a third coat for even coverage
• Poor existing condition — cracked plaster, flaking old paint, damp staining — all of which need treating before colour goes on, and can add a full day to what looks like a simple room
• A lot of woodwork — skirting, doors, frames, picture rails all add cutting-in time that doesn’t show up in the square-footage of the walls
• High ceilings, which need towers rather than a stepladder and slow down the ceiling coat specifically
• More than one tradesperson working around each other in a small space, which sounds like it should speed things up but often doesn’t

If you’re doing it yourself

Budget more time than you think, particularly for drying between coats — painting a bedroom over a single weekend is realistic if the walls are already in good condition; painting a whole house in a weekend generally isn’t, however many people you put on it. Preparation is the step people skip under time pressure, and it’s the one that shows up first — usually within a few months, as edges lift or filled cracks reappear.
