Polished Concrete: A Slab Turned Statement
Mechanically ground and polished concrete that is as practical in a warehouse as it is beautiful in a kitchen extension.
Diamond grinding & polishing • Overlays & toppings • Sealing & densifying
Make an EnquiryThe most honest floor in the building.
Polished concrete is not a coating, it is the structure of your building refined into a finished surface. Mechanically ground, densified and polished, it delivers a floor with no seams to fail, no layers to delaminate and almost nothing to maintain.
Flowfloor specify the exposure and gloss level around your slab and your use case, from a subtle salt-and-pepper matt in a retail unit to a full-aggregate mirror finish in a showroom.
Where an existing slab is not suitable, we install polishable overlays to achieve the same look on almost any base.
Minimal maintenance
No waxing or coating cycles, a neutral clean keeps it looking sharp.
Any gloss, any exposure
Matt to mirror, cream to full aggregate, specified to your design.
Polished concrete options
From grind-and-seal on a budget to full mechanical polish, we will tell you honestly what your slab can achieve before any work starts.
Mechanically polished concrete (MPC)
The premium, longest-lasting finish for new or good existing slabs.
Grind & seal
A cost-effective polished look using surface sealers.
Polishable overlays & toppings
A new 10-15mm surface where the existing slab will not polish.
Densifying & dustproofing
Harden and seal industrial slabs without a full polish.
Polished concrete flooring across the UK
Flowfloor design and install polished concrete floors for commercial, industrial and domestic projects nationwide. Because the finished floor is your slab, every project starts with an honest assessment of what you already have — then we specify the grind depth, aggregate exposure and gloss level to suit the space, the traffic and the budget.
Commercial polished concrete floors
For showrooms, retail units, restaurants and offices, polished concrete delivers a floor that shrugs off footfall and point loads while looking considered rather than industrial. There are no joints to trap dirt, no vinyl to lift at the seams and no coating to rewax every quarter. We programme commercial installations in phases — overnight and weekend working included — so trading floors stay open while we work.
Industrial and warehouse floors
In warehouses and production areas, a mechanically polished or densified slab cuts dust, stands up to forklift traffic and reflects light back into the racking aisles — many of our clients see a measurable drop in lighting costs after polishing. Where a full polish is more than the operation needs, grind-and-densify gives you the durability without the gloss.
Polished concrete at home
Kitchen extensions are where polished concrete has earned its place in British homes. Poured across underfloor heating and polished to the exposure you choose, it gives an extension one continuous, seamless surface from wall to wall — easy to clean, impossible to stain with the right seal, and never in need of replacing. For renovations where the existing slab won't take a polish, a polishable overlay of 10–15mm achieves the same finish over almost any sound base.
Outdoor and external polished concrete
Externally, we finish concrete with exposed-aggregate and honed finishes rather than a high polish — the same family of techniques, specified for grip and weathering. It's a popular way to run one visual surface from an open-plan kitchen through to a patio.
Where polished concrete earns its keep
The spaces where clients tell us polished concrete has paid for itself.
Warehouses & logistics
Dust-proofed, light-reflective slabs that handle racking, forklifts and years of traffic without a wear layer to fail.
Showrooms & retail
A seamless, architectural finish that photographs beautifully and cleans with a neutral mop.
Kitchens & extensions
One continuous surface over underfloor heating — warm in winter, effortless to keep clean.
Bars, restaurants & venues
Spill-proof with the right densifier and seal, and character that only improves with age.
What affects the cost of a polished concrete floor?
Polished concrete is priced by what the slab needs, not just by the square metre. When we quote — always after a site visit and usually a test grind — the main factors are:
- The condition of your slab. A flat, hard, modern slab polishes economically. Soft, uneven or contaminated concrete needs more grinding passes, repairs, or an overlay.
- Aggregate exposure. A cream polish (minimal grinding) costs less than a full-aggregate exposure that takes several deep passes.
- Gloss level. Every step up from matt to mirror is another polishing stage on site.
- Area and access. Large open floors are efficient; small rooms, stairs and edges take proportionally longer.
Because of this, we don't publish flat rates — but we will always tell you the most economical route to the look you want, including when grind-and-seal will do the job for less.
How we install a polished concrete floor
- Survey and test grind. We assess hardness, flatness and moisture, and grind a sample patch so you can see exactly what your slab will give before you commit.
- Preparation and repairs. Cracks, joints and surface damage are repaired; where needed we lay a polishable overlay — see our screeding and subfloor preparation service.
- Grinding and densifying. Progressive diamond grinding to the specified exposure, with a densifier hardening the surface between passes.
- Polishing and sealing. Resin-bond polishing to the agreed gloss, finished with a penetrating sealer matched to the use — stain-resistant in kitchens, slip-conscious in wet areas.
- Handover. You get a simple, honest maintenance sheet: a neutral clean, no waxes, no recoating schedule.

Polished Concrete FAQs
The questions we get asked most about polished concrete.
Can my existing concrete floor be polished?
Usually, it depends on the slab hardness, flatness and any contamination. We carry out a test grind before quoting so there are no surprises.
Is polished concrete slippery?
Dry, it typically meets slip resistance standards similar to other hard floors, and anti-slip additives are available for wet areas. We’ll match the finish to your slip-risk assessment.
Is it cold underfoot?
Concrete conducts heat well, which makes it one of the best floors for underfloor heating, warm in winter, cool in summer.
How long does installation take?
A typical 100m2 domestic polish takes around a week including cure times. Larger commercial floors are programmed in phases around your operation.
What is the difference between mechanically polished concrete and grind & seal?
Mechanically polished concrete (MPC) is ground, densified and polished so the shine comes from the concrete itself — it is the harder-wearing, longer-lasting finish. Grind & seal achieves a similar look faster by applying a sealer over ground concrete; it costs less up front but the sealer becomes the wear layer and needs periodic renewal. We will tell you honestly which suits your slab and budget.
How much does polished concrete cost per m² in the UK?
It depends on your slab's condition, the aggregate exposure and the gloss level you choose — a cream polish on a good modern slab sits at the economical end, while full-aggregate mirror finishes and overlay systems cost more. We quote after a survey and test grind, so the price reflects your floor rather than a generic rate.
Can polished concrete be used in an extension with underfloor heating?
Yes — it is arguably the best floor for it. Concrete's thermal mass spreads and holds the warmth, and there are no boards or vinyl to insulate the heat away. We coordinate with your builder on slab spec and cure times so the pour is polishable from day one.
Can you polish a garage or outbuilding floor?
Usually, yes. Garage slabs are often ideal candidates for a grind-and-densify or grind-and-seal finish that kills dust and resists tyre marks. If the slab is thin or damaged we will say so at the survey and price an overlay instead.
How do I clean and maintain a polished concrete floor?
A dust mop and an occasional damp mop with a neutral (pH 7) cleaner is all it needs. Avoid acidic or bleach-based products, which can dull the seal. Unlike coated floors there is no waxing or recoating cycle — that is most of the point.
