We see interior walls as more than room partitions. They can be beautiful surfaces that regulate indoor climate, show off texture, and connect people to natural materials.
Earthen Clay Plasters: Healthy, Breathable, Beautiful
Earthen plasters give you a wall finish that is non-toxic, natural, and fully breathable. Apply them over conventional substrates (or on full earth walls), and you gain:
- Regulation of indoor humidity and temperature
- A reduction in off-gassing and build-up of trapped moisture
- A low carbon footprint, using local clays, sands and fibers with minimal processing
- Endless aesthetic possibility — from sleek and modern to textured, artistic, or sculptural
Finish styles
- Contemporary & smooth (but never dead-flat)
- Subtle textures or bold patterns, custom-designed on request
- Sealed with a clear casein wash or natural sealers for durability and dust protection
Colours
Our standard clay tones are golden yellow and near white. We can blend in iron oxides (yellow, red, black) to achieve custom hues while staying entirely natural.
Substrate compatibility
We can plaster over a variety of surfaces, including:
- Concrete block
- Brick veneer
- Fiber cement boards / plasterboard (GIB)
- Strawbale / natural wall systems
Earthen Feature Walls in Timber-Framed Buildings
When you want to bring the benefits of earth into a lighter structure, interior feature walls are a great solution. Our interior adobe veneer adobe or earth boards:
- Tie back to the frame for secure support
- Provide thermal mass, acoustic damping, and visual warmth
- Are compliant under NZ Earth Building Standards
- Bring texture and material richness without needing full-mass walls
Whether you prefer subtle earth backdrop or expressive focal wall, we tailor the scale, thickness, and finish to suit your design.
Natural Plasters and Feature Walls Consultation & Installation
We don’t just supply materials — we support your build. We’re happy to:
- Review your plans and provide detailed quotes for materials, plastering or wall installation
- Carry out material sampling to your specifications
- Install natural plasters or earthen feature walls to best practice
- Teach you or your crew how to mix, apply, and finish earthen finishes correctly
You get both the confidence and control to bring earthen design into your project.
Benefits of Earthen & Clay Wall Finishes
- Moisture buffering: Clay is hygroscopic, which means that earthen surfaces absorb and release water vapour indoors, reducing mould risk. Even thin plaster layers can effectively regulate indoor humidity.
- Temperature regulation: Interior earthen features are high thermal mass, which means they can store and release warmth.
- Mould / rot resistance: Because clay surfaces dry out and breathe, they discourage conditions favourable to mould, unlike painted or sealed walls where moisture can get trapped.
- Natural and local: No synthetic additives, just raw clay, sand, fibres. These are surfaces that continue the ethos of earth throughout your building.
