Walls in Lithos Terra (LTH·II) — Bone

Its walls finished in Terra in Bone — the natural, unpigmented tone of the clay itself, the plaster reads as one continuous, seamless plane — complementing the honed stone of the stair, grounding the sculptural forms in soft earthen light, with the subtle tonal variation only clay leaves behind.

Walls in Lithos Terra, Bone — in quiet conversation with the stone.

The material

The oldest material in architecture. Refined for its finest.

Clay is not a trend that arrived in architecture — it is where architecture began. The walls of Çatalhöyük were clay-plastered nine thousand years before the first paint chart; the kasbahs of Morocco were raised from it, Japan refined it into an art, and every civilisation that built to last, built with earth.

Then, in a single modern century, we changed course. We now spend nine-tenths of our lives indoors, sealed behind acrylic paints and synthetic resins — surfaces that off-gas quietly into the rooms where we sleep, work and raise families. The wall is the largest surface in every room, and the least questioned.

Clay is the answer humanity had already tested for ten thousand years. A living mineral surface whose charged structure regulates humidity, starves mould of the damp it needs, and releases nothing synthetic — because the healthiest thing a wall can add to a room is nothing at all.

And no synthetic surface has ever matched the way it looks. Clay holds a depth that flat paint cannot imitate — light moves across it through the day, its subtle tonal and textural variation carrying the hand of the artisan who laid it. No two walls are ever the same, and none ever need to shout: clay grounds a room, connects its materials, and grows more beautiful as it ages rather than less.

From the earthen pavilions of the Venice Biennale to the studios of the world’s most considered practices, architecture is returning to earth. Claywise was founded to make Australia’s contribution to that return — natural clays blended here, proven on the country’s most celebrated projects, placed only by accredited hands.

In practice

Every Claywise finish is a system, not a single coat. On average, five stages, tuned to each finish: a mechanical slip coat to key the substrate, base coats to build the body, an intermediate coat to refine it, finish coats laid by trowel, and a choice of natural protection — sealers or waxes — to suit the room. It is applied over prepared substrates including plasterboard, correctly prepared cement sheeting, cement render and sound painted surfaces.

The Lithos Collection Four grades of one material

Lithos — from the Greek for stone — is the founding collection of Claywise. Four grades of one material, from raw to luminous.

LTH 01

Cruda

Clay in its rawest expression

The honest, unpolished surface of the earth itself. Cruda holds the movement of the trowel that placed it.

Walls & ceilings · interior
LTH 02

Terra

The grounded body of the collection

Warm, balanced surfaces with a soft matte depth. The grade we reach for most — it reads calm in daylight and warmer again by lamplight.

Walls & ceilings · interior
LTH 03

Lumen

The finest grade

The finest-graded of the four. A smooth, luminous surface that carries light softly across a room — where most people who think they know clay change their mind about it.

Walls & ceilings · interior
LTH 04

Earth Plaster

The heavy-bodied grade

Large natural aggregates and a deep, sculptural texture — a strong finish with real presence, for walls that are meant to be felt.

The maker

Built by the hands that apply it

Claywise wasn't started in a marketing meeting. It was started on the wall — and the wall goes back a long way. Eric Moroney first picked up a trowel in Ireland at fifteen; by twenty-one he was being trusted with work usually reserved for plasterers twice his age. Two decades of application later — the last decade and more inside Australia's most exacting homes, as founder of Lusso Venetian Finishes — that apprenticeship has never really ended.

Claywise began as a frustration. Eric loved clay — its depth, its breath, its honesty — but the clay plasters available to him kept failing his standard: too soft, too brittle, unable to hold their place in the calibre of projects he was trusted with. He knew the material didn't have to be that way. So began five years of blending, proving and refining, batch by batch, on live projects — until the answer existed: a clay plaster with all the beauty and benefits of earth, that holds its own in any environment, and remains one hundred per cent natural. Claywise existed on walls long before it existed on a bag.

The Sample Box

Clay photographs beautifully. It feels even better.

Designers tell us clay is the most photogenic surface they work with. But the photograph is only half the experience — so we send the material itself, finished by hand in our workshop.

Accreditation Applications reviewed monthly

Placed only by accredited hands

Claywise is a curated blend of natural clays, engineered for durability. It is one hundred per cent natural, and never sold through broad distribution — supply runs through Claywise and a small circle of appointed stockists, and it is placed by accredited installers only.

Accreditation is deliberate. Installers are selected by portfolio, assessed hands-on, and certified through the Claywise Academy — then supported on live projects with technical detailing, site presence, and a material-and-system warranty available only on accredited work.

A note for specifiers. A Claywise specification describes a system: the material, the accredited installer, and the manufacturer’s support behind both. Alternative clays in unaccredited hands sit outside that system and outside its warranty. Where the schedule reads Claywise, placed by a Claywise-accredited installer, the specification is not interchangeable.

Applications are open. Accreditation is limited by region and reviewed annually.

Common questions Asked by architects, answered plainly
Can any plasterer apply Claywise?
No — and that's deliberate. Claywise is supplied only to accredited installers, certified through the Claywise Academy. Clay rewards patience and punishes shortcuts; accreditation is how we make sure every wall carrying our name deserves it. If there's no accredited installer in your region yet, write to us — that's often how new regions open.
Can it be used in bathrooms and kitchens?
Yes, with judgement. Clay is at home in kitchens, powder rooms and bathrooms outside areas of direct water contact. For shower enclosures and splash zones we detail an appropriate mineral finish alongside it — something we advise on per project, so the room reads as one material story.
What happens if a wall is damaged?
This is clay's quiet advantage. Because the material never chemically sets the way cement or acrylic systems do, a Claywise surface can be locally re-wetted and re-worked by an accredited installer. Repairs blend into the wall rather than sitting on it — a clay wall is meant to be lived with, and mended, for decades.
How do I specify Claywise on a project?
Order the Sample Box, then write to us with your drawings. We'll confirm the grade, colour and texture, supply specification clauses and technical data sheets for your documentation, and connect you with an accredited installer for pricing. Specification enquiries are answered by our technical team within one business day.
Where does the clay come from?
Our plasters are blended in Australia from natural clay minerals, carefully selected mineral aggregates and mineral pigments. Every batch is checked against a retained master standard before it leaves the workshop — consistency is the whole game in a natural material, and it's the part we refuse to compromise on.
