Decora Diamond Floor · Microcement · Melbourne
Measured in millimetres. Built to be lived on.
Decora Diamond Floor is a thin mineral coating — two to three millimetres, troweled by hand — that turns floors, walls and wet areas into one seamless surface. No grout. No joins. Over almost any substrate, with no demolition.

Decora Diamond Floor · Anthracite · Residential
The whole room,
in one surface.
Decora Diamond Floor is the microcement we use — an Italian, resin-based system made in Sicily by Decora A&C. Silica-free, water-resistant once sealed, and laid grout-free over concrete, tile, timber or plaster. No demolition, no grid, no joins to fail.
One continuous mineral surface, with the depth of the Italian decorative tradition and nowhere for the eye to stop. Floor to wall to benchtop, the same finish runs through the room.

One finish.
Every surface.
Specified to the substrate and to how the room actually gets used. Floors take the traffic, walls take the light, wet areas take the water — all the same hand, all the same finish.
01Floors
Continuous flooring that runs from kitchen to hallway without a single join. Hard-wearing, low-profile, warmer underfoot than concrete has any right to be.
02Walls
Floor-to-ceiling for a fully integrated room, or one quiet feature wall. A satin-smooth mineral depth you can't paint on or print.
03Stairs
Treads and risers wrapped in one jointless surface. A staircase that reads as a single poured form, not a stack of parts.
04Wet Areas
A seamless, water-resistant bathroom with no grout to mould, crack or discolour. The continuous wet-room look, detailed properly — over a certified membrane.
05Joinery
Benches, vanities and built-ins wrapped seamlessly; sinks and splashbacks integrated with no visible edge. A stone alternative, without the silica.
A surface for an industry
that changed.
Most cement- and stone-based surfaces carry crystalline silica — the dust behind Australia's 2024 engineered-stone ban and the tighter workplace rules that followed. Decora Diamond Floor doesn't.
No respirable silica means a safer cut on site for the people who install it, and a healthier surface for the people who live and work on it.
The seamless concrete look, without the trade-off.
- No crystalline silica
- Low dust
- Compliant
- Healthier site
Same look.
Different physics.
Tile has its place. A continuous mineral floor is a different proposition — one surface where tile gives you a grid.
Traditional Tile
- Grout lines throughout
- Relies on grout & sealant holding
- Grout is the usual failure point
- A modular, gridded look
- Usually demolition or overlay board
- Many tiles & adhesives carry silica
Decora Diamond Floor
- Seamless, grout-free
- One continuous water-resistant finish
- No grout to harbour mould
- One uninterrupted surface
- Goes straight over sound tile
- Silica-free
What the surface does.
Water Resistant
Sealed, seamless protection across wet and dry areas.
Silica Free
No crystalline silica; safer for installers and occupants.
Low VOC
Low-odour, low-VOC formulation for healthier interiors.
Flexible & Strong
A resin-based system with give and mechanical strength.
15+ Year Lifespan
Built to last with simple, regular care.

From $200 per square metre, depending on area, substrate and surfaces involved. Quoted individually.
Yes, a single system for both; the same finish runs floor to wall to benchtop with consistent colour and texture.
Yes, over a compliant waterproofing membrane, with no grout lines to fail. The microcement is the finished surface; waterproofing sits beneath.
In most cases, yes — straight over with the right primer, no demolition. Tiles must be sound and firmly bonded.
Installed and sealed properly, 15 years or more with straightforward care.
