How to Clean Microcement — and What to Do About a Chip or Scratch

The short version: to clean a microcement floor, sweep or vacuum first, then mop with a soft microfibre mop and warm water with a pH-neutral cleaner, keep vinegar, bleach, ammonia and abrasive powders off it permanently, and treat a scratch or chip as a sealer problem, not a floor problem — a professional sands the patch back and reseals it, rather than replacing anything. Microcement’s whole reputation for being low-maintenance rests on a topcoat doing quiet, invisible work every day, and almost everything that goes wrong with a microcement surface traces back to something being poured, sprayed or scrubbed onto that topcoat that should not have been. That sealer is the main con on any honest list of microcement pros and cons, and the routine below is how you keep it from becoming one.

What to clean it with

A microfibre mop or cloth, warm water and a few drops of a pH-neutral cleaner is the entire routine for a floor or wall in ordinary use. There is no special “microcement cleaner” you need to buy — a pH-neutral floor cleaner sold for natural stone or laminate works exactly the same way here, because it is the sealer, not the mineral coating underneath, that the product is actually cleaning. Wipe up spills as they happen rather than letting them sit, dry the surface after mopping in a wet zone, and that is genuinely the whole job.

What to keep off it, permanently

The sealer is a polyurethane or similar topcoat, and it reacts to chemistry the same way any lacquered surface does:

• No vinegar, lemon juice or descaling products. Acids etch and dull a sealed finish over repeated contact — the same rule we give for tadelakt and lime plaster, because it is chemistry, not marketing.
• No bleach or ammonia-based cleaners. These attack the topcoat’s clarity and can leave a permanently hazy patch that no amount of later cleaning fixes.
• No abrasive powders or scouring pads. Microcement is smooth by design; a scouring pad puts fine scratches into the sealer that dull the sheen exactly where you scrubbed hardest.
• No steam cleaners. Sustained heat and moisture pushed at a sealed coating is a fast way to soften and lift it.

Every one of these is a withdrawal from the topcoat’s working life, covered in more depth in how long does microcement last and is microcement waterproof. The floor is not fragile — it is specific about what touches it, which is a different thing.

How a chip or scratch actually gets repaired

A visible chip, a deep scratch from a dragged appliance, or a dull patch where something acidic sat too long is a sealer-level injury almost every time, and it is repaired at that level, not by tearing anything out:

1. The damaged area is assessed. A scratch through the topcoat only needs resanding and resealing; a chip that has gone through to the cement body needs a small patch of matching coloured coating trowelled in first.
2. The patch is lightly sanded to key the surface and remove the damaged sealer, blending the edges rather than working a hard-edged square — this is the step that decides whether a repair disappears or reads as a patch.
3. Colour is matched and, if needed, reapplied in the same pigmented coating as the original job. This is why the installer who did the original work is the right person to call: they know the exact mix and can source or match it faithfully.
4. The area is resealed with the same topcoat grade as the surrounding surface — a dry-area sealer indoors, an immersion-grade one in a wet zone — so the patch performs identically to the rest of the floor, not just matches it visually.

Done properly, a repaired patch in microcement blends far better than a cracked or chipped tile ever can, because the material is continuous and hand-worked rather than a manufactured unit with a visible edge. This is also why we treat repair as a call-out, not a DIY product: colour-matching a mineral pigment and feathering a sealer edge is the same skill that laid the floor, and a mismatched patch is more visible, not less, than the damage it was meant to hide.

What is not repairable this way

A hairline that traces back to substrate movement — covered in full in does microcement crack — can be filled and blended the same way, but if the substrate is still moving, the same line reappears until the movement is addressed. Repairing the coating without addressing an active structural cause treats the symptom, and we say so on-site rather than resealing the same patch twice.

The bottom line

Microcement asks for less daily care than tiled grout ever did — a soft mop, a neutral cleaner, and the discipline to keep acids and abrasives away from it — and when something does mark it, a trained hand can make the repair disappear rather than leave a permanent scar.

Microcement cleaning FAQ

How do you clean a microcement floor, step by step?

Sweep or vacuum with a soft head to lift sand and grit, which is what scratches the sealer. Mop with warm water and a small dose of pH-neutral floor cleaner, wring the microfibre mop well so you are not flooding the surface, and dry any standing water. Once a week is enough in most homes; entrances, kitchens and homes with pets may need it daily.

What is the best microcement floor cleaner?

Any mild, pH-neutral floor cleaner without acids, bleach, ammonia or solvents. Avoid “tile and grout” cleaners, limescale removers and vinegar mixes — they attack the sealer. Some installers supply a maintenance product matched to their sealer; if yours did, use that. If you are not sure, a drop of neutral soap in warm water is safe.

Can I use a steam mop on microcement?

We advise against it. Repeated high heat and pressurised steam are hard on the protective sealer, and a damaged sealer is what lets stains in. A damp microfibre mop does the job.

How do you clean microcement in a shower?

Rinse and squeegee after use so hard UAE water does not leave lime spots, and wipe weekly with a neutral cleaner. For limescale, use a cleaner labelled safe for sealed natural stone — never an acidic descaler.
