A lustrous, marble-like lime finish — burnished by hand to a deep sheen with light and movement drawn from the material itself, across Melbourne's most considered heritage and contemporary interiors.
Polished plaster belongs to Mousi's family of architectural decorative finishes — materials specified for their composition and the way they hold light, rather than imitative surface treatments. It is a lime-based finish applied by hand in fine layers and burnished until the surface carries a smooth, lustrous, marble-like depth from within.
The result is alive to light. Where paint sits flat, a polished plaster surface gathers and reflects light, shifting from soft satin to deep sheen as the room changes. That luminous, hand-burnished quality is why it remains a reference finish for feature walls, ceilings and heritage interiors across Melbourne.
Applied across residences, hospitality venues and commercial interiors throughout Melbourne.
Because the colour and lime are part of the plaster itself, a polished surface carries a luminosity and movement that a film of paint cannot reproduce. The depth is structural — built through the layers and brought up by burnishing, not printed on.
Each surface is built by hand and burnished between coats, so the sheen and movement belong to that room alone. The level of polish — from soft satin to high, marble-like gloss — is specified to suit the architecture and its light.
Every polished plaster surface is assessed against its substrate, its light and its use before a finish is committed. These are the considerations that shape the specification.
A polished finish reveals everything beneath it. Surfaces are assessed, repaired and primed to a smooth, even ground so the plaster builds and burnishes predictably across the whole plane.
Sheen is chosen for how the surface will be lit — a high burnish for reflective, marble-like depth, or a softer satin where the room calls for restraint. The same colour reads differently at each level.
Colour is built through the layers rather than applied at the end, allowing tonal depth and movement. The final specification — colour and sheen — is recorded so it can be matched exactly in years to come.
Polished plaster earns its place where a surface is meant to be seen and to catch light — the feature wall in a living room, a burnished ceiling, the walls of a heritage drawing room or a refined commercial interior.
Across Melbourne's premium residential and commercial interiors, Mousi specifies it where the architecture asks for a material with luminous presence rather than a flat coat of colour.
Polished plaster is unforgiving of shortcuts. Mousi's craftspeople follow a disciplined sequence — from the first sample board through to the final burnish — so the surface you approve is the surface you receive.
We read the wall before we touch it — its substrate, the light it carries and how the finish will be seen. The specification follows the room, not a template.
Surfaces are repaired, levelled and primed to a smooth, even ground. A polished finish reveals everything beneath it, so this unseen stage decides the result.
Base coats are applied to key the substrate and establish an even ground for the polished layers to build on.
Thin layers of lime-based plaster are applied and worked by hand, each one building the colour, translucency and depth that define a polished surface.
The final layers are compressed and burnished, drawing the surface tight and bringing up the sheen and luminosity from within the material.
Where the setting calls for it — splash zones, high-touch surfaces — a protective treatment is applied to add resistance without dulling the polish.
Your approved colour, sheen and specification are recorded in your Property Passport™ — a permanent record that lets the finish be matched and maintained for years, supported by Mousi Care™.
Mousi works alongside Melbourne architects and interior designers as a finishing partner — not simply an applicator. From early concept through to site, we help develop, prove and specify polished plaster so the sheen and colour read on the wall the way they read on the board.
Finished boards prepared in your specified colour and sheen, viewed in the project's own light for design review and client sign-off.
At-scale mock-ups on representative substrates, so the finish can be assessed against adjacent materials, joinery and lighting before commitment.
Iterative development of colour, sheen and burnish until the surface resolves the design intent rather than approximating it.
Clear written specifications and schedules your documentation can reference, with substrate and protection notes for the builder.
Bespoke colour and texture development for projects that need a finish outside the standard range — matched to a palette, a stone or a brief.
Coordination through design and construction — sequencing, substrate readiness and site conditions — so the finish is protected on a live job.
A disciplined sequence, distilled. Each stage protects the one before it, so the surface you approve on the sample board is the surface you live with.
We assess and correct the substrate, then prime to a smooth, even ground so the plaster builds and burnishes predictably.
The final layers are compressed and burnished, drawing the surface tight and bringing up the sheen and luminosity from within the material.
Where the setting calls for it, a protective treatment is applied for resistance in splash zones — without dulling the polish.
In heritage rooms, polished plaster sits naturally against original cornice, arches and joinery — a hand-finished lime surface sympathetic to the period, with a soft, luminous depth that flat paint cannot match.
In contemporary interiors it does something bolder: a burnished feature wall or ceiling that animates as light moves across it. The same material, two registers — period refinement or modern drama.
Mousi specifies polished plaster across Melbourne's architect-designed homes, luxury residences and hospitality interiors — including heritage and contemporary projects throughout Toorak, South Yarra, Brighton and Hawthorn. In each, the brief is the same: a luminous, hand-burnished lime surface judged against the room's own light, applied by hand and recorded for the life of the building.
It is one of several architectural materials we apply in-house. See the full range on our Decorative Finishes page, or explore Venetian Plaster, Limewash and Microcement.
Each of our mineral finishes answers a different brief. This is how polished plaster sits alongside the alternatives — a reference for specification rather than a ranking.
| Consideration | Polished Plaster | Venetian Plaster | Microcement | Conventional Paint |
|---|---|---|---|---|
| Appearance | Lustrous, marble-like sheen with luminous depth | Polished, luminous depth with light held within the surface | Seamless, contemporary, mineral-matte | Flat, uniform colour sitting on the surface |
| Texture | Smooth, burnished, from satin to high gloss | Smooth and burnished, subtly tactile | Fine, continuous, hard-wearing | Even film with no inherent texture |
| Durability | Hard mineral surface; sealable for splash zones | Hard mineral surface; sealable for wet areas | Highly durable across floors and walls | Wears as a film; can chip and peel |
| Maintenance | Maintained surface; ages gracefully, re-burnishable | Maintained surface; ages gracefully, re-burnishable | Low maintenance; periodic re-sealing | Repainted periodically as the film fails |
| Suited To | Feature walls, ceilings, heritage and refined interiors | Feature walls, entrances, considered interiors | Floors, bathrooms, continuous modern surfaces | General-purpose walls and ceilings |
The right finish is chosen for the room, the light and the brief — see Venetian Plaster, Limewash and Microcement.
A sense of how polished plaster resolves real briefs across Melbourne's heritage and contemporary interiors — the surface, the light and the outcome.
Polished plaster across the walls of a heritage drawing room, set against original cornice, arches and a marble fireplace. The brief was a hand-finished lime surface that would feel true to the period yet bring a soft, luminous depth the rooms had lost. The finished walls glow as the light moves through the day — refined, warm and unmistakably hand-applied.
A sculptural curved gallery hall where polished plaster wraps the walls and soffit, its soft sheen carrying light around the curve beside a black steel stair. The finish was developed to read evenly around the radius and to set off the owners' artwork. The result is a refined, luminous circulation space that turns the corner as one continuous surface.
A sculptural plastered form — a curved range hood — finished in polished plaster so the sheen turns the soft geometry beside a brass sconce. The brief was a seamless, hand-burnished surface that would read as a single sculpted object rather than a clad box. The result is a quiet, luminous centrepiece where material and form resolve as one.
A penthouse living space where polished plaster lines the walls and a structural column, its sheen catching the city light against floor-to-ceiling glazing. The brief called for a refined, luminous material to carry a luxury interior at height, set against stone and timber. The result is a calm, reflective backdrop where the finish quietly elevates the whole room.
A Hawthorn period home where polished plaster was specified through the living and dining rooms, set against original joinery, a fireplace and high ceilings. The brief was a hand-finished lime surface sympathetic to the home's heritage, with a soft, luminous depth that paint could not give. The finished walls carry the light gently through the day — refined, warm and true to the architecture.
A handmade surface deserves a record. Mousi documents every polished plaster project so the finish can be matched, re-burnished and protected long after the work is complete — preserving the investment in the material and the craft.
