How Long Does Microcement Last?

The part that wears is the part you can replace

A microcement finish is built in layers: preparation and primer, reinforced base coats, fine finish coats, then a sealer system. Day to day, your shoes, your dog and your kitchen chairs never touch the cement — they touch the sealer.

That matters, because a worn sealer is not a failed floor. It is re-coated over the existing surface: clean, prepare, re-apply, and the floor reads as new again. Compare that with tiles, where a worn or dated floor means demolition, skip bins and a week of your house being a building site.

How often it needs re-sealing

It depends almost entirely on traffic and what happens on the surface. A feature wall or a hallway in a quiet home may go many years without needing anything beyond normal cleaning. A busy family kitchen with a door to the pool, sand underfoot and chairs scraping twice a day is at the other end of the range.

Wet areas and benchtops sit in their own category because they meet water, heat and household chemicals constantly. We give you the maintenance interval for your specific job and the sealer we used on it, in writing, when we hand it over — rather than a number off a website that has never seen your house.

What actually shortens a microcement floor's life

• —Moisture coming up from below — a slab with no working vapour barrier will push moisture into any finish laid on it. This is why we moisture-test before quoting, not after.
• —A wet area built without a proper waterproofing system underneath — microcement is not the waterproofing, and a bathroom that relies on the finish to keep water out is a leak with a date on it.
• —Harsh cleaners — bleach, acidic bathroom sprays, oven cleaner and supermarket 'heavy duty' degreasers attack sealers. A pH-neutral cleaner is all it needs.
• —Grit — the single biggest cause of dulled floors anywhere. Sand and grit are sandpaper underfoot, which is what doormats are for.
• —Dragging furniture — felt pads on chairs and lifting rather than sliding heavy things.
• —Standing water left sitting for days, particularly at edges and junctions.
• —Being used before it has cured — the most avoidable one of the lot.

Floors, benchtops, walls and outdoors age differently

• —Walls and feature walls — effectively permanent. Nothing abrades them, so they stay as installed.
• —Floors — the benchmark surface for microcement: hard-wearing, seamless, and renewable by re-sealing rather than replacing.
• —Wet areas — long-lived when the waterproofing system underneath was built properly, and short-lived when it was not. The finish is rarely the variable.
• —Benchtops — the hardest life in the house. Heat, red wine, lemon juice and knives all meet the same surface, so the sealer specification and day-to-day care matter more here than anywhere else.
• —Outdoors — UV and weather are the ageing factors rather than foot traffic, which is why exterior work uses a UV-stable system. Expect some natural mellowing outside over the years; it is a cement finish, not a laminate.

It ages like a material, not like a product

Microcement is a hand-troweled cement finish, and it develops character the way stone and concrete do. That is the point of it. If you want a surface that looks identical on day one and day four thousand, you want a manufactured product, and we will tell you that honestly rather than sell you something you will be disappointed by.

What you should not accept is failure: lifting, crazing across a whole floor, staining that will not clean, or water getting where it should not. That is not ageing. That is installation.

The renewal advantage

The reason we are comfortable talking in decades is that microcement can be brought back without being removed. A tired floor can be cleaned and re-sealed. A damaged area can be repaired and blended. A floor whose colour no longer suits the house can be re-coated on top of itself.

Very few finishes give you that. It also means the honest question is not just how long the finish lasts, but how long until it costs you again — and for microcement, that is usually a re-seal rather than a renovation.
