Thinking of creating polished plaster walls on a surface in your home? Here’s an expert guide we’ve put together to help you. 5 key facts with everything you need to know about using polished plaster in your interior design project.

Firstly let’s start by answering the most important question.

What are polished plaster walls?

Polished plaster is a decorative plaster finish which you apply to any type of surface. It produces a smooth uniform decorative finish that has a beautiful texture.

Polished plaster is an umbrella term for a wide range of decorative plasters. Each having a unique quality in terms of origin, colour, texture and technique. The different types of plasters vary in texture from very smooth and highly polished finishes to matt or pitted finishes. Extremely durable, they are a luxurious choice for interior surfaces adding bespoke finish with depth and character.

Here’s our top 5 list of exactly what you need to know about using Polished Plaster in your home

1. A hygenic breathable surface

This means that the plaster allows moisture to escape out through the surface of the plaster. This is ideal for wet rooms, such as bathrooms and showers. Additionally one of the key ingredients of the plaster is slaked lime. Lime is highly alkaline which as well as reducing moisture retention helps to inhibit the growth of bacteria, mould and mildew in damp areas.

2. Polished plaster is waterproof

The highly durable smooth surface is naturally waterproof. It is also possible to further enhance polished plaster walls with the addition of a protective wax coating. This creates an impenetrable waterproof seal. For best effect apply a top-up coat from time to time – which is easy to apply.

3. Low in VOCs

Polished plaster has a high percentage of natural ingredients. Unlike traditional plasters and paints it is low in VOCs – volatile organic compounds. These are the solvent based by-products which release into the atmosphere from building materials such as paint and plaster. In addition to leaving nasty lingering smells, they are known to have adverse effects on respiratory health. For added shine a final seal is provided by a natural beeswax coating. Alternativley there’s is also a sealing coating available which is vegan and free of animal products.

4. Precision matching to a range of colours


With the ability to match from the RAL colour system there is an almost limitless range of colours available. RAL is a European standard in colours for construction and architecture. Most commercial paint brands have RAL colour code matches for their colour charts.
