Walk into any well-finished home, and chances are the walls are clean, crisp, and smooth. Behind that polished surface? Often, it’s the result of plaster skim — a time-tested finish that continues to be the backbone of quality interior wall preparation.
In this guide, we’ll explain exactly what plaster skim is, why it remains so popular across UK homes, and whether it’s the right solution for your space.

What Is Plaster Skim?
Plaster skimming is a method used to apply a very thin coat of finishing plaster (often around 2–3mm) to internal walls or ceilings. The goal? A smooth, even surface ready to be painted or decorated.
It’s often done in one of two scenarios:
- ✅ Over new plasterboard or dry lining (e.g., in extensions or new builds)
- ✅ Over existing, uneven, or damaged plaster, to refresh old walls
It’s typically the final stage in the plastering process — the surface you see, touch, and decorate.
What Materials Are Used for Skimming?
At P3 Plastering, we most commonly use multi-finish plaster, such as British Gypsum’s Thistle MultiFinish. It’s versatile, workable, and ideal for both board and float surfaces.
Other options may include:
- Board Finish – for plasterboard only
- Finish Coat over bonding plaster – for float and set jobs
- One Coat plasters (used more rarely in domestic skimming)
The Skimming Process: Step-by-Step
If you’re wondering what actually happens during a skim coat job, here’s a quick overview:
Surface preparation
- Cleaning, applying bonding agents (like PVA)
- Filling any major cracks or holes
First coat of plaster
- Applied with a hawk and trowel
- Spread smoothly in an even layer
Second coat
- Applied while the first is setting
- Helps achieve a flawless surface
Troweling and smoothing
- Multiple passes with the trowel as it dries
- Edges are feathered and smoothed
Final polish
- A tight pass ensures minimal imperfections
- Once dry (usually after 3–5 days), it’s ready for painting
Why Is Skimming So Popular?
Skimming has stood the test of time in UK homes for several key reasons:
✅ Provides a Perfect Base for Painting
No bumps, cracks, or flaky patches — just a crisp surface that enhances paint and wallpaper.
✅ Restores Tired or Uneven Walls
Don’t want the mess of full replastering? Skim coats are ideal for giving old walls a fresh start.
✅ Cost-Effective
Compared to float and set or full replastering, skimming is quicker and more affordable — especially for renovation or decoration.
✅ Adds Value to the Home
Whether you’re selling or staying, smooth, well-finished walls signal a well-maintained property.
When Is Skimming the Right Choice?
✅ Best for:
- Covering new plasterboard
- Minor imperfections or old painted surfaces
- Light cosmetic upgrades
- Refreshing ceilings
🚫 Not ideal if:
- Plaster underneath is blown or damaged
- There are signs of moisture/damp
- Wall levels are uneven and require backing plaster
In those cases, a float and set method or plasterboarding may be more appropriate (and we offer that too!).
How Long Does Skimming Take?
This depends on the room size and conditions. Here’s a general guide:
Area | Time (avg.) |
Small bedroom | 1 day |
Large lounge | 1.5 days |
Full 3-bed home | 4–6 days |
Drying time (before painting) | 3–7 days depending on ventilation |

- Full homes: project-dependent
