Do Your Walls Need Skimming or Plastering?

If your walls are uneven, cracked, or looking tired, you might be wondering whether they need skimming or full plastering.

While both improve the finish of your walls, they’re used in different situations. Choosing the right one can save time, money, and unnecessary work.

Skimming vs plastering

The main difference comes down to how much work your walls need.

Skimming is a thin layer of finishing plaster applied over existing walls to create a smooth surface
Plastering usually involves building up layers from scratch or repairing deeper damage

Skimming is ideal for:

smoothing out minor imperfections
refreshing old plaster
preparing walls for painting or decorating

Full plastering is needed when:

walls are badly damaged or uneven
old plaster has failed
new plasterboard has been installed

Does my wall need skimming or plastering?

This depends on the condition of your walls.

You’ll likely need skimming if:

the surface is mostly sound but slightly rough
there are small cracks or marks
the wall just needs a clean, smooth finish

You’ll likely need plastering if:

the wall is crumbling or unstable
large areas are damaged
plaster has blown or come away from the wall

If you’re unsure, a quick inspection from a professional can usually determine the best approach.

Is skimming easier than plastering?

Yes — skimming is generally quicker and less labour-intensive than full plastering.

Because it’s applied as a thin layer over an existing surface, it requires:

less preparation
fewer materials
less time on site

However, getting a perfectly smooth finish still takes skill, so it’s not always as easy as it looks.

Is skimming a wall cheaper than plastering?

In most cases, yes — skimming is cheaper than full plastering.

That’s because:

it uses less material
it takes less time
it involves less structural work

Full plastering tends to cost more due to the extra preparation and labour involved, especially if walls need to be repaired or rebuilt first.

Can you just skim over old plaster?

Often, yes — you can skim over existing plaster, as long as it’s in good condition.

Before skimming, the surface needs to be:

stable and well-bonded
free from major cracks or loose areas
properly prepared (usually sealed with a bonding agent)

If the underlying plaster is damaged or unstable, skimming alone won’t fix the issue and full plastering may be required.

Choosing the right option for your walls

The best approach depends on the condition of your walls and the finish you want to achieve.

If you’re dealing with minor imperfections, skimming is often the quickest and most cost-effective solution. For more serious damage, full plastering will give a stronger, longer-lasting result.

If you’re unsure which option is right, it’s always worth getting advice before starting work.
