Caring for a Magnesite Floor

The one rule that governs everything else: magnesite flooring is cared for dry. The salt-bound magnesium oxychloride binder that gives it its warmth and seamlessness is also what standing water dissolves, so the entire maintenance routine exists to keep water off the floor, not to remove dirt — dirt is the easy part.

The daily and weekly routine

Dust or dry-mop first, every time. A soft-bristle broom or a microfibre dust mop lifts grit before it can grind into the surface underfoot — the single most useful habit for any seamless floor, and doubly so here since magnesite is softer than terrazzo or polished concrete and marks more easily under gritty traffic.

Damp, never wet, for anything beyond dust. A cloth or mop wrung out until it is barely moist, with a pH-neutral cleaner, is the ceiling of what a magnesite floor should ever see. Work in small sections and follow behind with a dry cloth so no moisture sits on the surface or pools at a skirting. If a mop leaves visible wet streaks, it was too wet.

No standing water, ever — not even briefly. This is the one line that cannot bend. A spilled drink, a leaking plant pot, an AC condensate drip left overnight: all of it needs lifting and drying immediately, not “getting to later.” Repeated or prolonged wetting is exactly what leaches and softens the binder, and it is the single most common way historic magnesite floors were damaged.

What to keep off it

• Acidic or ammonia-based cleaners — vinegar, descalers and many general household sprays can react with the chloride-bound binder. A neutral floor cleaner, used sparingly and diluted, is the safe choice.
• Steam mops and pressure washing — both drive water and heat straight into a surface that is defined by its intolerance of exactly that.
• Steel wool or abrasive scouring pads — they scratch a matte mineral surface that cannot be buffed back to gloss the way a sealed resin floor can.
• Standing furniture without pads — magnesite is softer underfoot than terrazzo or concrete, so chair legs and heavy furniture without felt pads will dent it over time.

Refreshing the surface

A magnesite floor is a living mineral surface, not a sealed one, and its sheen fades with years of foot traffic the way any traditional trowelled floor’s does. Refreshing it — typically a maintenance coat of oil or wax worked back into the surface — is a job for whoever restored or laid the floor, since the right product depends on how that specific floor was originally finished. If you inherited a period magnesite floor and don’t know its history, that is the first question to ask a restorer before applying anything to it yourself.

If water does get on it

Lift it immediately with a dry cloth or towel, then let the area air freely — open a window, run the AC, don’t seal the room up while it’s still damp. A quick, one-off wetting that is dried straight away is not the same emergency as water left to sit; the danger is duration, not the occasional accident. If a leak has been going on for a while before anyone noticed, or a section starts to feel soft or looks discoloured, that’s a job for a specialist, not a mop.

Why this floor asks for more care than the others we lay

Every other seamless floor we install — microcement, tadelakt, polished concrete — is built specifically to shrug off water, including full wet zones for microcement and tadelakt. Magnesite is the one exception in our range, kept alive mainly for heritage restoration and the rare dry interior that wants its particular warmth. If a household’s real routine involves mop buckets, spills and a bathroom nearby, that is honestly a sign the room wants one of those instead — see our full comparison in is magnesite flooring practical for a UAE home.
