Polished Concrete Floors Ireland
Everything you need to know about polished concrete floors in Ireland — cost, installation, pros, cons and how it compares with microcement.
What Are Polished Concrete Floors?
Polished concrete floors are exactly what the name suggests: an existing concrete slab that has been mechanically ground with diamond abrasive tools and progressively polished to a high sheen. The process removes the surface layer of concrete, exposes the aggregate below and creates a reflective, hard-wearing surface.
Polished concrete has a distinctive industrial aesthetic that suits certain architectural styles very well — warehouses converted to apartments, contemporary commercial spaces and new-build homes designed around exposed concrete are the natural home for this finish.
However, polished concrete comes with significant limitations for renovation projects — which is why many Irish homeowners and contractors who research it ultimately choose microcement floors instead.
The Polished Concrete Process
Grind
Heavy diamond grinding equipment removes the surface layer of concrete and any coatings. This stage determines the depth of aggregate exposure.
Hone
Progressively finer grits are used to smooth the surface. Each pass removes the scratches from the previous stage.
Polish
Fine polishing pads bring the surface to the desired sheen level — from satin to high gloss. A chemical hardener is often applied at this stage.
Seal
A penetrating sealer is applied to protect the porous concrete and provide stain resistance. Ongoing maintenance sealing is required annually.
Microcement vs Polished Concrete
| Criteria | Microcement | Polished Concrete |
|---|---|---|
| Requires concrete slab | No — any stable substrate | Yes — existing slab required |
| Installation on timber floors | Yes | No |
| Suitable for bathrooms | Yes — fully waterproof | No — too porous |
| Suitable for walls | Yes | No |
| Thickness added | 2-3mm only | None (grinds existing) |
| Cost installed | €80 – €140/m2 | €80 – €200/m2 |
| Colour options | 22 standard + custom | Limited by aggregate colour |
| Crack risk | Low — flexible system | Higher — concrete shrinks |
Recommendation: For most Irish renovation projects, microcement is the more practical choice. If you have a new industrial build or warehouse conversion with an existing concrete slab and want to retain its character, polished concrete is worth considering. For everything else, microcement delivers the same aesthetic with far fewer limitations.
