Who this guide is for
- Homeowners wanting smooth walls before decorating
- People unsure what a skim coat involves
- Renovators specifying the level of finish they expect
- Anyone comparing smooth and textured wall finishes
What level of finish means
Walls can be finished to different standards, from a basic, slightly textured surface to a smooth, decoration-ready finish. The level you want should be agreed in advance, because it shapes the work and the result.
Vague expectations about smoothness are a common source of disappointment.
- Finish ranges from textured to smooth
- The level should be agreed in advance
- It shapes both the work and the look
- Clarity avoids later disappointment
What a skim coat achieves
A skim coat is a thin finishing layer applied to create a smooth, even surface ready for decoration. It is often used over existing walls or new boards to lift the finish to a higher standard.
It is the route to the smooth walls many people expect from a quality job.
Smooth versus textured finishes
A smooth finish suits contemporary schemes and shows off paint cleanly, but it is unforgiving of later damage. Textured finishes can hide imperfections but read differently and are harder to change.
The choice depends on your taste and how the wall will be used.
Planning and communicating the finish
Because finish quality is subjective, it helps to describe what you want clearly and to view examples. Agreeing expectations with the plasterer up front gives the best chance of a result you are happy with.
A plasterer can advise what is achievable on your particular walls.

Frequently asked questions
Questions readers ask about this topic
What is a skim coat?
It is a thin finishing layer applied to a wall to create a smooth, even surface ready for decoration. It is often used over existing walls or new boards to lift the finish to a higher, smoother standard.
Do all walls need a skim coat?
Not necessarily. The right approach depends on the wall's condition and the finish you want. A skim coat is the common route to a smooth, decoration-ready surface, but a plasterer can advise what suits your walls.
Why do my walls look textured after work?
Different finishes leave different amounts of texture, and if the level was not agreed in advance the result may not match expectations. Discussing and viewing the finish standard before work begins helps avoid this.
Is a smooth finish always best?
Not universally. Smooth finishes suit contemporary schemes and show paint cleanly but are unforgiving of later damage, while textured finishes can hide imperfections. The choice depends on your taste and how the wall is used.
