If you're working on a wall or ceiling project, you've probably heard the terms plastering and skimming, and may be wondering what the actual difference is between the two. Although they’re closely related techniques in the world of internal wall finishes, knowing when to plaster vs. when to skim can help save time, improve results, and ensure you’re using the right tools for the job.

In this guide, we’ll break down the difference between plastering and skimming and share the essential tools every tradesperson or DIYer needs to get the job done right.

What is Plastering?

Plastering is the process of applying a thick layer of plaster (usually 6mm–13mm) to a bare surface, such as brick, blockwork, or plasterboard, to create a smooth, level finish. It's often done on new builds or renovations where the internal walls are rough or uneven.

Plastering typically requires a full set of tools and materials, including:

A Mixing Tray or Plasterers Mixing Bucket to prepare your plaster mix
A Plasterers Bath for larger-scale work
A Hawk for holding and applying plaster to the wall
A Float for achieving a smooth, even surface

What is Skimming?

Skimming is a finishing technique where a thin layer (around 2–3mm) of finishing plaster is applied to an already-plastered or plasterboard surface. Its purpose is to smooth out imperfections and create a flawless surface ready for painting or wallpapering.

Skimming is commonly used when:

You’re refreshing old or damaged plaster
You're covering plasterboard joins
You need a high-end finish without full plaster depth

The tools you’ll need for skimming are often the same as plastering, including a hawk and float, but with an emphasis on finer control and a smoother finish.
