Drylining a room: how long it takes, what to expect and aftercare

Updated 6 November 2026 · By the Drylining team

Short answer: Drylining a typical room usually takes two to four days: a day or two for boarding, then one or two days for taping and jointing or skimming, plus drying time before decorating. Taped joints can usually be primed within a day of finishing, while skimmed walls need several days to a week to dry before a mist coat.

Typical timescales

Job	Typical time on site	Drying before decorating
One room, dot-and-dab and tape and joint	2 to 3 days	About a day
One room, dot-and-dab and skim	3 to 4 days	Several days to a week
Stud partition with door, finished	2 to 3 days	A day to a week depending on finish
Ceiling overboard and skim, one room	1 to 2 days	Several days to a week
Insulated lining to external walls, one room	3 to 5 days	Depends on finish

These are typical guide times for a small team. Larger jobs, high ceilings, lots of openings and waiting for other trades all add time.

Preparing the room

Clear the room of furniture, or move it to the centre and cover it
Take down curtains, blinds, pictures and shelves
Ask your electrician to isolate or disconnect sockets and lights on affected walls
Arrange for radiators to be drained and removed where walls are being lined
Agree where heavy items such as TVs, shelves and kitchen units will go
Make sure there is somewhere to stack boards and a route to bring them in

What happens on the day

Work usually starts with protecting floors and setting out: marking the wall lines, socket positions and openings. Old plaster or boards are removed if that is part of the job, which is the dustiest stage. Then frames are built or adhesive is applied and boards are fixed and cut around openings. Electricians and plumbers usually need access between framing and boarding on stud walls. Finishing follows once boards are fixed and adhesive has set. Expect noise from cutting and screwing, and some fine dust from sanding if the joints are taped and jointed.

With dot-and-dab, the adhesive needs to set before finishing starts, which usually means boarding one day and finishing the next. With tape and joint, each coat of compound has to dry before the next, so finishing is often spread over two or three short visits. Skimming is normally done in a single visit per room, with two coats applied while the first is still workable. Building control inspections, if needed, may also have to happen before boards go on.

Drying and decorating

Jointing compound usually dries in a few hours to a day depending on the product and conditions
Skim plaster dries from dark to an even light pink, which can take a few days to over a week in cold, damp weather
Keep the room ventilated and gently heated, but do not blast heaters at fresh plaster, which can cause cracking
Use a drywall primer or a mist coat of thinned emulsion first, then normal emulsion
Avoid vinyl or wipeable paints as the first coat on fresh plaster as they can trap moisture

Fixing things to plasterboard afterwards

Item	Suitable fixing
Light pictures and mirrors	Plasterboard plugs or self-drill fixings
Shelves and medium loads	Spring or gravity toggles, or metal cavity anchors
TVs, radiators, wall cupboards, basins	Fix into noggins, pattresses or studs, or through dot-and-dab into masonry with frame fixings
Very heavy items such as wall-hung boilers or large TVs on brackets	Planned reinforcement in the frame before boarding

Always use a cable and pipe detector before drilling, and keep within safe zones for cables, which normally run vertically or horizontally from sockets and switches.

Common questions afterwards

Hairline cracks at internal corners or ceiling junctions in the first months are usually caused by the building settling or timber drying, and are dealt with when decorating. Raised screw heads, called pops, can appear where boards were not pulled tight or timber shrinks, and are easily refixed and filled. Anything larger, such as long open cracks along joints or a board that moves when pushed, should be reported to the installer.

Living with the work

Drylining is far less disruptive than full wet plastering, but it still affects the room for a few days. Boards are large and heavy, typically 2.4 m by 1.2 m, so they need a clear route through the house and somewhere flat to be stored. Cutting is usually done with a knife and rasp rather than power saws, which keeps dust down, but removing old plaster and sanding joint compound both create fine dust that travels.

Close internal doors and seal gaps with dust sheets or tape where possible
Cover or remove soft furnishings in neighbouring rooms
Turn off or cover smoke alarms near the work during dusty stages, and turn them back on each evening
Expect boards and materials to be delivered a day or so before work starts
Keep children and pets away from the work area, as cut boards and screws can be sharp
Plan for heating to be off on walls where radiators have been removed

If you are living in the house, ask the installer to agree a daily finish time and a tidy-up routine, so rooms that are not being worked on stay usable each evening.
