Concrete Screed Flooring: Finishes and Care

Concrete screed flooring is a cement-and-sand layer laid over a structural slab and finished to become the visible floor. In most buildings, screed is a hidden levelling bed beneath tiles or timber. Left exposed, trowelled smooth and sealed, it gives the soft grey, slightly mottled surface associated with industrial and minimal interiors. It is honest, seamless and relatively simple in principle, but it is a hand-made, site-made finish: no two floors look the same, and some hairline cracking should be expected.

This guide explains how a screed floor is laid and finished, what affects its appearance and durability, how it compares with microcement and concrete-look vinyl, and what to expect on cost and care. It sits within our guide to other finishes.

What concrete screed flooring is

The terms are often used loosely, so it helps to be clear.

Concrete slab: the structural floor of the building, containing coarse aggregate and steel reinforcement.
Screed: a finer mix of cement, sand and water, laid over the slab to level it and bring it to the right height. It contains no coarse aggregate.
Cement screed floor finish: a screed that is trowelled, sometimes burnished or polished, and sealed so that it can serve as the finished floor.

When people ask for a concrete screed floor at home, they usually mean the third: a decorative cement finish rather than exposed structural concrete. True polished structural concrete, ground to reveal aggregate, is a different process; our guide to concrete floor polish covers it.

How a screed floor is laid

Preparation. Existing finishes are removed and the slab is cleaned. Any waterproofing in wet areas is completed and tested first.
Levels and falls. The installer sets the finished height so the floor meets doors, thresholds and adjoining rooms, and builds falls towards drains where needed.
Laying. The screed is mixed, spread and compacted, then levelled with a straight edge. Factory pre-blended screed mixes give more consistent results than mixing on site.
Trowelling. As the screed stiffens, it is trowelled by hand or machine to close the surface. The timing and pressure of this step create much of the floor’s character: the cloudy marks, burnished patches and subtle tonal shifts.
Curing. The screed must cure slowly and evenly, protected from rapid drying. Rushing this stage increases shrinkage cracking and dusting.
Sealing. Once dry, the floor is sealed to resist stains and dusting.

Each stage depends on skill and conditions, which is why the same specification can produce noticeably different floors from different teams. Ask to see finished floors by the same installer, ideally a few years old.

Finishes and sealers

The look of a cement screed floor comes from the trowelling and the sealer.

Matt sealer: closest to the raw look. Shows wear and stains a little more readily.
Satin sealer: a soft sheen that deepens the colour and is easier to clean. A common choice for homes.
Gloss or epoxy coating: high shine and good stain resistance, but scratches show and it can feel more commercial.
Tints and pigments: colour can be added to the mix or the sealer, from warm greys to off-whites and charcoal. Pigmented screed is rarely perfectly uniform; that variation is part of its appeal.

Sealers wear with use and need periodic reapplication, more often in kitchens and entrances than in bedrooms.

Cracks, dusting and honest expectations

Cement shrinks as it cures. In a continuous floor, that shrinkage shows as fine hairline cracks, particularly at corners, doorways and over joints in the slab below. Good practice reduces them: a correct mix, careful curing, and control joints at sensible intervals and at door thresholds. It rarely eliminates them entirely.

Hairline cracks are usually cosmetic. Many owners accept them as part of the material.
Wider or moving cracks can signal structural movement or a poor bond to the slab, and should be checked.
Dusting, a powdery surface, usually comes from a weak surface layer or inadequate sealing.
Hollow sounds when tapped can indicate the screed has debonded from the slab.

If a perfectly crack-free, uniform floor matters to you, a cement screed is probably not the right choice.

Concrete screed flooring compared with alternatives

Option	Thickness and weight	Look	Main trade-off
Cement screed finish	Thicker, heavier	Raw, variable, industrial	Hairline cracking; site-dependent quality
Microcement	A few millimetres over a sound base	Fine, seamless, refined	Skilled application; needs a stable substrate
Epoxy or resin coating	Thin	Smooth, can mimic concrete	Can feel plasticky; scratches show
Concrete vinyl flooring	Thin planks or tiles	Printed concrete look	Repeating pattern; joints visible
Concrete-look porcelain	Tile and adhesive bed	Consistent, durable	Grout lines

Microcement is often chosen where a screed would raise floor levels too much, or where tiles must be overlaid without hacking. Our material page on microcement explains the system.

Concrete vinyl flooring is the most practical way to get the colour without the cracking: printed vinyl tiles or planks with a concrete visual, laid over a level base. Up close, the pattern repeats and joints show, so it reads as a reference to concrete rather than the material itself. Our guide to vinyl flooring covers wear layers and installation.

Concrete screed flooring in Singapore homes

Cement screed suits a hot climate well. It is cool underfoot and works with tropical modernist, industrial and minimal interiors. A few local points:

Condominiums. Floor works involve hacking, noise and material movement, so check MCST by-laws and approval requirements before starting.
Levels. Laying screed over existing tiles raises the floor and may affect doors, thresholds and kitchen cabinets. Hacking first avoids this but adds cost and noise.
Humidity. With the mean annual relative humidity around 82%, curing and sealing schedules need care. Sealing before the screed is properly dry can trap moisture and cause clouding.
Wet areas. Cement screed is porous until sealed. In bathrooms, the waterproofing beneath matters more than the finish on top.

Cost: what drives the price

Cost depends on area, whether existing floors are hacked, the thickness and type of screed, the finishing technique, sealer and the installer’s skill. As context, one Singapore cost guide lists basic screeding or re-levelling, the base layer under other finishes, at about S$1 to S$3 per square foot, and hacking plus screeding at about S$4 to S$11 per square foot, according to this 2026 flooring cost guide. A decorative, trowelled and sealed screed floor costs more than a levelling bed, because of the finishing labour and sealer. These figures are indicative, vary by project and are not a Keneki quote.

Care and maintenance

Sweep or vacuum grit regularly, as it scratches the sealer.
Mop with a pH-neutral cleaner. Avoid acidic and strongly alkaline cleaners, which damage sealers and etch cement.
Wipe oil, wine and coffee spills promptly.
Use felt pads under furniture.
Reseal when water no longer beads on the surface in high-traffic areas.

Frequently asked questions

Will a concrete screed floor crack?

Some hairline cracking is normal as cement shrinks. Good mixing, curing and control joints reduce it. Wide or growing cracks should be investigated.

Is concrete screed flooring cold or hard underfoot?

It is hard and feels cool, which many people enjoy in Singapore. Rugs soften living and sleeping areas.

Can screed be laid over existing tiles?

Sometimes, if the tiles are sound and the added height is acceptable. Microcement is often the thinner alternative for overlays.

Is concrete vinyl flooring a good substitute?

It gives a similar colour with no cracking and less mess, but it looks printed up close. It suits rentals and quick refurbishments.
