Cleaning and maintaining microcement: a practical care guide

Cleaning and maintaining microcement is simpler than most people expect. The surface is continuous and sealed, so there are no grout lines to scrub and far fewer places for dirt to settle. Most of the work comes down to protecting the sealer, the layer that shields the finish from wear, water and stains.

This guide covers an everyday routine, the products and habits to avoid, how to deal with spills and how sealer maintenance fits in over time. If the care advice you receive at handover for your specific sealer differs from the general guidance here, follow the handover advice.

Why microcement care starts with the sealer

Microcement itself is not waterproof. Once a suitable sealer is applied as the final layer it becomes water-resistant, and the sealer also protects against wear and stains while enhancing the colour. In practice, it is the sealer you are cleaning.

Three things wear a sealer faster than anything else: grit that grinds underfoot, harsh chemicals that dull or break down the protective layer, and liquids left long enough to mark. Avoid those and most of the work is done. For more on how water and sealing interact, see our guide on whether microcement is waterproof.

Cleaning microcement: an everyday routine

A light, regular routine is better than an occasional deep clean. For most floors, walls and benchtops, this sequence works well.

1. Remove loose dust and grit with a soft broom, a dry microfibre dust mop or a vacuum fitted with a soft brush head.
2. Dilute a pH-neutral cleaner in clean water at the strength recommended on the label.
3. Damp mop with a well-wrung microfibre mop, so the surface is damp rather than wet.
4. Change the water once it looks cloudy, so you are not spreading dirt back across the floor.
5. Let the surface air-dry, or buff it with a dry microfibre cloth to avoid streaks on darker colours.

How often depends on the room. A busy entry or kitchen floor may need grit removed daily and a damp mop several times a week, while a bedroom wall may only need an occasional wipe with a soft, damp cloth.

What to avoid

Most damage to sealed microcement comes from the wrong products or tools rather than from everyday use. Keep these away from the surface.

• Abrasive pads, scourers, steel wool and stiff-bristled brushes.
• Harsh acids, including descalers and vinegar-based mixtures.
• Bleach, ammonia and cleaners that contain them.
• Solvent-based cleaners and strong degreasers.
• Excess water, such as a soaking-wet mop or water left pooling on the surface.
• Steam cleaners, unless the care advice for your sealer specifically allows them.

Spills and stains

A sealed surface buys you time, not unlimited time. Red wine, coffee, tea, juice, cooking oil and cosmetics can all leave a mark if they sit for long, particularly where the sealer is starting to wear.

Blot liquids with a soft cloth or paper towel rather than wiping, which can spread them. Then clean the area with a cloth dampened in a pH-neutral solution and dry it. For oily marks, repeat with a little more of the same cleaner instead of switching to a degreaser.

If a mark remains, resist the urge to scrub harder or reach for stronger products, which can do more harm than the stain. Take a photo and ask us for advice instead.

Furniture, rugs and everyday wear

Microcement resists traffic, knocks and scratches, but concentrated pressure and trapped grit are hard on any sealed finish. Fit felt pads to chair and table legs, check them now and then for embedded grit, and lift furniture rather than dragging it.

Office chairs on hard castors can wear a path over time, so soft castors or a suitable chair mat help. Entrance mats catch grit before it reaches the floor; choose ones with a backing suited to sealed hard floors. On heated floors, avoid rugs and furniture that trap heat, as our underfloor heating guide explains.

The first week after completion

Microcement keeps hardening and gaining strength for several weeks after application, so the first week calls for a lighter touch than your long-term routine.

• Limit the surface to light foot traffic, ideally in socks or soft-soled shoes.
• Stick to dry dusting and prompt spot-wiping until you are advised that regular damp mopping can begin.
• Hold off on returning heavy furniture, appliances and rugs until you are told the surface is ready.
• If other trades need to come back, agree how the finished surface will be protected.

Bathrooms and kitchens

Bathrooms

With no grout lines for grime and mould to settle into, a microcement bathroom is easier to keep clean than a tiled one. Squeegee or towel-dry shower walls and floors after use, run the exhaust fan or open a window, and clean regularly with a pH-neutral product so soap and mineral residue never build up. Skip acidic descalers and bleach-based mould sprays. Our page on microcement bathrooms shows how the finish is used.

Kitchens

Benchtops and splashbacks deal with oil, acidic foods and heat. Wipe up oil, citrus, vinegar, tomato and wine promptly, use chopping boards rather than cutting directly on the surface, and put hot pots and pans on a trivet. For more on the surface itself, see microcement kitchens.

Maintaining the sealer over time

Every sealer wears gradually with traffic and cleaning. How soon it needs attention depends on the sealer used and on how hard the surface works, so a busy hallway will need care sooner than a bedroom wall. Follow the handover advice for the sealer on your project, which is specific to that product.

When to ask for a maintenance check

• Traffic paths look dull or worn compared with the rest of the surface.
• Water darkens the finish or soaks in rather than sitting on the surface.
• A stain will not lift with a pH-neutral cleaner.
• You notice a chip from an impact or a fine line in the finish; our guide to whether microcement cracks explains the difference between surface marks and cracks.
• The way the space is used is changing, such as a quiet room becoming a busy workspace.
