Freshly skimmed walls can make a tired room feel completely different, creating a smooth finish that's much easier to decorate.

Whether you're renovating an older property, covering dated textured surfaces, or preparing walls for decorating, skimming creates the smooth finish most homeowners are looking for.

But how much does it cost to skim a room?

The answer depends on several factors, including:

• The size of the room

• The condition of the existing plaster

• Whether ceilings are included

• Whether you're simply re-skimming existing walls

• If you're plastering from scratch

This guide breaks down the typical cost to skim a room, what affects the price, how long the work takes, and when it's worth calling in a professional plasterer.

Average cost to skim a room in the UK

The cost to skim a room typically ranges from £430–£550, with a medium-sized room costing around £480 on average.

Budget reality check

A straightforward re-skim of a room with sound existing plaster is usually one of the more affordable plastering jobs, averaging around £24 per m².

However, if walls need repairing first, ceilings require overboarding, or the room needs plastering from scratch, costs can rise quickly. That's why it's worth getting a plasterer to inspect the room before setting a firm budget.

Cost to skim a room by project type

Not every skimming project is the same. The final price will depend on the condition of your walls and whether the room simply needs a fresh skim coat or more extensive plastering work.

Re-skimming existing walls

If the existing plaster is generally sound, a plasterer can often apply a fresh skim coat directly over the surface. This is usually the most cost-effective option.

Typical costs for re-skimming are:

• Small room (around 2m x 2m): £440

• Medium room (around 3m x 3m): £480

• Large room (around 6m x 5m): £650

Plastering and skimming from scratch

Where walls are badly damaged, stripped back, or newly constructed, more extensive plastering work may be required before skimming. This involves creating a new plaster surface before applying the finishing skim coat.

Typical costs are:

• Small room (around 2m x 2m): £636

• Medium room (around 3m x 3m): £755

• Large room (around 6m x 5m): £1,300

Ceiling skimming costs

If your ceiling also needs attention, costs will increase accordingly. Ceiling work can be more labour-intensive because plasterers are working overhead and often need additional preparation time.

Average costs for skimming a ceiling are:

• Small room (9m²): £275

• Medium room (15m²): £360

• Large room (25m²): £575

What is skimming plaster?

Skimming plaster is the process of applying a thin finishing coat of plaster over existing plaster or plasterboard to create a smooth surface ready for decorating.

It's commonly used to:

• Refresh tired walls

• Cover minor imperfections

• Prepare surfaces for painting

• Cover textured finishes such as Artex

Skimming differs from plastering from scratch because the underlying wall structure is already in place.

What affects the cost of skimming a room?

Several factors can influence the final cost of skimming a room, including:

• Room size: Larger rooms require more materials and labour

• Condition of the walls: The more preparation work needed, the higher the cost is likely to be

• Ceilings: Including ceilings increases labour time and material requirements

• Accessibility: High ceilings, awkward stairwells, and restricted access can all increase costs

• Existing finishes: Covering Artex or heavily textured surfaces often requires additional preparation

Additional costs to budget for

When pricing a skimming project, it's worth considering a few possible extras that could crop up.

These can include:

• Wallpaper removal

• Ceiling overboarding

• Radiator removal and refitting

• Furniture moving

• Waste disposal

• Access equipment

• Repairs to damaged plaster

Not every project will require these elements, but they can affect your overall budget.

How long does it take to skim a room?

The time needed to complete the work depends on the size and condition of the room.

As a guide:

• Small room: Around 1 day

• Medium room: 1–2 days

• Large room: 2–3 days

After skimming, the plaster must also dry fully before any decorating can begin. As an indicator of when this is, fresh plaster often changes from a dark brown colour to a pale pink before it's ready for paint.

Cost of hiring a plasterer vs DIY

It's tempting to look at a few online videos and wonder whether skimming is something you could tackle yourself.

While it might look straightforward, achieving a smooth finish takes skill and practice.

A wall can look perfect while wet, only for trowel marks, ridges and uneven areas to become obvious once the paint goes on.

DIY may be suitable if:

• You're practising in a low-visibility area

• The room is small

• You already have plastering experience

Hiring a professional is usually worthwhile if:

• You want a high-quality finish

• You're decorating immediately afterwards

• The room is large

• Ceilings are involved

Tips to keep skimming costs down

You can help keep costs lower by:

• Preparing the room beforehand: Strip wallpaper and clear furniture beforehand to help prepare the room. This will save your plasterer time and could reduce your overall cost

• Combining projects: If you need several rooms skimmed, consider getting them all done at the same time. This could lower your cost per room as your plasterer will already be on-site

• Comparing several quotes: Requesting quotes from a selection of local plasterers will help to ensure you receive a fair and competitive price for the work

• Are ceilings included?

• Is the existing plaster in good condition?

• Does wallpaper need removing?

• Are repairs required first?

• Will decorating follow immediately afterwards?

When should you speak to a plasterer?

Sometimes skimming alone is all that's needed. However, if the plaster is cracked or blown, the walls sound hollow when tapped, Artex needs covering, or ceilings are sagging, it's worth speaking to a plasterer early on.

An experienced plasterer can advise whether skimming is appropriate or whether more extensive plastering work is required.

Can I just skim over old plaster?

Yes, if your old plaster is in good condition, you can skim over it. However, it will need to be properly prepared first. Our guide on how to prepare your home before plastering has everything you need to know.

Can I skim a room myself?

Yes, if you have the right skills and experience, you may be able to skim a room yourself. However, creating a smooth and even finish is a lot harder than it looks. For the best results, it’s a good idea to hire a plasterer.

To learn more, check out our guides on how to skim a wall and how to plaster.

How soon can I paint after skimming a room?

You should usually wait between 3–7 days after a skim coat has been applied before painting. However, exactly how long you should wait will depend on the thickness of the plaster and the ambient temperature.

The important thing is to wait until the plaster is completely dry. Our guide on how long you should wait before painting on newly skimmed walls has more.

Can you paint directly onto freshly skimmed walls?

Yes, you can paint directly onto freshly skimmed walls. However, it’s important to water down your first layer of paint, which is known as a mist coat. This is because fresh plaster is extremely porous. So, if you don’t do a mist coat, the plaster will absorb the water within the topcoat.

You can find out more in our guide to painting on new plaster — or simply find a painter and decorator who will be sure to get things right the first time around.

How long does it take for plaster to dry after skimming?

A skim coat will usually take 3–7 days to dry. However, walls that have been plastered from scratch could take up to 4 weeks. You’ll know when plaster is fully dry because it will change colour from brown to an even, light pink colour.

Head over to our guide on how long plaster takes to dry to learn more.

The terms skimming and plastering are often used interchangeably. But skimming is actually a type of plastering. There are several different techniques that plasterers might use, and skimming is just one of them.

Usually, it’s seen as the final stage of plastering a wall or ceiling — although if your walls and ceilings are in good condition, this may be all you need. To give you a rough guide:

• Skim coats are generally very thin and applied to a thickness of up to 5mm

• Plaster can be applied to a thickness of anywhere from 5mm to 30mm

• Skimming a medium-sized room costs on average £480

• Plastering a medium-sized room from scratch (which will include skimming) costs around £755
