How Long Does Wall Panelling Take to Fit?

For a single average-sized room, professionally fitted half-wall or shaker panelling typically takes one to two days, including the finishing and painting. That's usually longer than people expect — not because the cutting and fixing takes so long, but because the finishing stage, which is where the quality really shows, can't be rushed.

Where the time actually goes

Measuring, setting out, and marking the wall — half a day for a room, longer if the wall is uneven and needs careful compensation
Cutting and fitting the mouldings — typically a day for a standard room
Filling nail holes and joints, then sanding — several hours, and filler needs time to dry properly before sanding
Priming bare MDF and any exposed nail heads — essential and needs drying time
Two coats of paint — each coat needs proper drying time before the next, which is often the part that stretches a job into a second day

What extends the timeline

Hallways and staircases, which involve more corners, raking cuts, and awkward angles
Walls that are significantly out of true, needing extra care to keep panel lines level and joints tight
Working around radiators, skirting, and sockets
Colder or more humid conditions, which slow down filler and paint drying times

Why rushing it is a false economy

Filler that hasn't fully dried before sanding crumbles or leaves a soft patch that shows through paint later. Paint applied over a coat that hasn't cured properly can go patchy or peel at the edges. A job that looks 'finished' after cutting and sticking is often only two-thirds done — the drying and curing time in between coats is unavoidable if you want a result that still looks right in a year, not just on the day.

Booking in

If you're planning around a booking, it's worth knowing decorating and panelling generally isn't a quick same-day job for anything beyond a small feature wall. Building in a day or two, and avoiding scheduling anything else in the room straight after, gives the finish the time it needs to properly cure.
