Living Naturally: Clay Plaster at Home & Work

Discover why clay plaster is the ultimate natural wall finish for living well

In today’s fast-paced world, many of us are seeking ways to slow down and reconnect with nature. A holistic lifestyle isn’t just about what we eat or how we meditate—it extends to the spaces we live and work in.  The space we occupy shapes our stress levels, sleep patterns and quality and overall wellbeing; and the materials we use can either nurture or drain our energy.   One powerful way to create a healthy, balanced home environment is by choosing natural building materials like clay plaster.

What is clay plaster?

Clay has been used in buildings for thousands of years; it’s a traditional building material (think wattle and daub). But clay plaster is now experiencing something of a renaissance in modern sustainable design and living. A totally natural wall finish, using natural clay to bind mixed aggregate, sand and natural fibre, not processed or fired, it offers a non-toxic, breathable and eco-friendly finish, unlike synthetic paints or cement-based plasters.

It adheres well to most stable, porous surfaces (e.g., lime or gypsum basecoats). Non-porous paint or glossy surfaces may need priming or mesh. It cannot be applied to substrates such as wood and metal.

What is the look and feel of clay plaster?

This is biophilic design in practice: bringing nature’s materials, colours and textures indoors to boost wellbeing. In its rawest form, clay plaster offers a textured matt finish, with the hand application creating subtle organic movement and depth, a soothing aesthetic and tactile warmth. Coupled with natural mineral pigments, an array of shades and hues can be achieved, from warm earth tones of ochres, terracottas, and umbers to cool, serene neutrals, greens, and blues.

Design tips: Where in the home does clay plaster work best?

• Clay plaster is equally at home in modern minimal interiors, rustic cottages, offices and wellness studios and can be used in most rooms.
• Create feature walls in living areas, with earthy colours to energise the space. In bedrooms and workspaces, the breathable nature supports better air quality, whilst its textured matt finish softens light reflection and acoustics for a calming atmosphere.
• Clay plaster is not suitable in wet areas, such as showers, wet rooms, saunas, steam rooms, or as splashbacks. But it can still be used in bathrooms and kitchens in areas away from direct splashing. It can be paired with lime plasters such as tadelakt, pastellone or tiles in wet spaces to generate contrast and interest.
• Because of its durability, clay plaster is perfect for areas such as hallways and stairwells. It is resilient and yet more forgiving than other harder finishes, and minor scuffs can be easily repaired.
• In heavier traffic areas, a topcoat or sealer can be applied to add more protection, or choosing a more textured finish can hide a multitude of sins!
• Paired with natural fabrics, such as wool rugs and linen cushions, and dressed with plants and wood accents, creates biophilic harmony.

Can clay plaster be used in commercial environments?

Absolutely! In a time where environmental responsibility is increasingly a core expectation, using clay plaster can improve sustainability credentials for businesses seeking to demonstrate their commitment to green practices, promoting healthier, more sustainable built environments.

Clay plaster is becoming increasingly popular in offices, retail, hospitality and wellness spaces due to its VOC-free qualities and ability to regulate humidity, reduce indoor pollutants and create a generally healthier indoor environment.

With its aesthetic flexibility, both in colour and texture, clay plaster is an attractive design solution for areas such as hotel lobbies, retail boutiques, cafes and restaurants and corporate reception areas and conference/meeting rooms.

As well as its eco-friendly credentials, what other benefits does clay plaster have?

In our previous blog on clay, we set out all the eco-credentials of clay: eco-friendly, sustainable, low carbon footprint, breathability and moisture and temperature regulation. But there’s more…

Cost:

Clay plaster material can be slightly higher than standard paint but compared to other decorative finishes, it offers great value for money particularly given its health and aesthetic benefits.

Compostable:

As clay plaster is unprocessed and contains no artificial materials, it can be recycled at the end of its use.

Maintenance:

In our busy lives, anything low maintenance is welcome.  Clay simply requires a dust with a soft brush.  For stains, lightly dampen, dab, or sand and reblend a small patch.  Avoid harsh detergents.

Where can clay plaster be used?

Clay plaster is particularly suited for residential or commercial interiors and is a very popular finish to walls and ceilings. Whether used throughout an entire property, in just one room or as an accent wall in a space, clay plaster can provide colour, texture and visual interest in the space.  Its heat resistance makes it ideal for finishes to fireplaces or chimney breasts, creating a standout feature. Whilst not waterproof, clay plaster can be used in bathrooms in areas not exposed to quantities of water and steam (such as shower enclosures or wet areas).
