Polished Concrete vs Microcement

The short verdict: if you have a sound concrete slab and can commit early, polished concrete is the better floor — it is the structure itself, it lasts the life of the building, and nothing you lay on top will outlive it. If you are renovating over existing tiles, screed or a slab of unknown quality, microcement is the right answer — it goes over almost anything at 2–3mm and gets you a seamless floor without demolition. The choice is decided by what is already on your floor and when you are asking, far more than by how the two finishes look.

They are often pitched as rivals. They are not really. One reveals a floor; the other adds one.

The fundamental difference

Polished concrete is not a coating. There is nothing added to your floor — we grind the existing slab, densify it chemically so the surface hardens, then work through progressively finer passes until it reaches the sheen you chose. What you end up looking at is the building. That is its great strength and its great constraint: the floor can only ever be as good as the slab it was poured from, and you cannot change that after the fact.

Microcement is the opposite proposition. A cement-and-polymer coating, 2–3mm thick, trowelled over a prepared substrate and sealed. It bonds to concrete, screed, existing tiles, plywood — almost any sound, stable base. It brings its own colour and its own trowelled movement, and it climbs walls and wraps into wet rooms in the same finish, which polished concrete cannot do.

Side by side

Full figures and what moves them are in the microcement cost guide. Both are supply and install, and both follow a site visit — with polished concrete especially, nobody can quote your floor honestly without seeing the slab.

When polished concrete wins

You are building, or the slab is already exposed and good. This is the ideal case and it is worth planning for. A slab poured with its future as a finished floor in mind — properly cured, level, without a rash of service trenches cut through it — polishes into a floor that will outlast everything else in the room. It is also the most economical premium floor available in that scenario, because the material is already bought.

You want genuine, permanent hardness. A densified concrete floor has no coating to wear through. In a showroom, a gallery, a busy entrance hall, that matters. Microcement’s sealer is a consumable; concrete’s surface is not.

The floor is the whole aesthetic. A polished slab has the mottled, aggregate-flecked honesty of real concrete — exposure of the stone within it, the ghost of how it was poured. Microcement is deliberately more even and more controlled. Some people want the building to show; if that is you, an imitation of concrete will never satisfy you.

When microcement wins

You are renovating. This is most people, and it is decisive. Taking up tile, breaking out screed, disposing of it, and discovering what is underneath is expensive, slow and unpredictable — and in an apartment it may not even be permitted. Microcement goes over the top. The job is measured in days, not weeks, and the existing floor stays where it is.

The slab is a lottery. In much UAE villa and apartment stock the slab was never intended to be seen: patched, trenched for services, poured to a tolerance that was fine for tiling and is not fine for polishing. Grinding it will reveal that history, permanently. Microcement covers it.

You want the floor and walls to match, or you want a bathroom. Microcement runs seamlessly from floor to wall to shower. Polished concrete simply cannot follow it there. Our microcement bathroom page covers the wet-zone build-up, and Dubai and Abu Dhabi pages cover the rest.

You want to choose the colour. A slab gives you the colour of the slab. Microcement gives you a palette.

The honest failure modes

Both floors can disappoint, and they disappoint differently.

Polished concrete disappoints when the slab is worse than anyone expected. Grinding is discovery: cracks, cold joints, patches and aggregate variation you did not know were there arrive all at once, and they are now the floor. Cracks in particular can be filled but never unseen — concrete moves, and a floor that is the structure will always tell you about it. We survey and, where there is real doubt, grind a test patch before anyone commits.

Microcement disappoints when the substrate moves. It is 2–3mm thick and it is only as stable as what is under it: a drumming tile, a flexing timber deck, a live crack in a slab, and the movement will eventually telegraph through. It also asks for its sealer to be respected and eventually renewed. Prep is 80% of the job and it is the thing cheap quotes cut.

So: which?

Ask two questions. Is there a slab, and is it good? If yes, and you can commit before it gets trenched and patched, polish it — you will not get a better floor for the money, and it lasts the life of the building. Is anything already on the floor you would rather not demolish? Then microcement, without much agonising; it exists for exactly that situation and it is very good at it.

If it is genuinely a coin toss — a decent slab, but you also want a specific colour and the walls to match — go microcement. Flexibility is worth more than purity in a house people live in.
