Microcement vs Cement Screed

Microcement vs Cement Screed in Singapore

Not the same thing.

Cement screed is the structural base under your finish. Microcement is the decorative surface you see and touch. People mix the two up constantly — here is the clean distinction.

This page compares the two build-up layers only. For pricing, scopes and where microcement is installed across a whole home, see the microcement Singapore pillar.

Microcement vs cement screed at a glance

	Cement screed	Microcement
Role	Structural substrate	Decorative finish
Thickness	20–50mm	2–3mm
Composition	Cement + sand + water	Cement + polymer resin + pigment + aggregate
Look	Grey, utilitarian, hairline cracks	Continuous, hand-trowelled, sealed cream tones
Where	Under tile, vinyl, or as raw industrial floor	Walls, splashbacks, bathroom walls, feature floors
Sealer needed?	Optional	Always (2 coats)
Cost	$4–7/sqft	$30–70/sqft

How the two layers stack in a real build-up

In almost every Singapore renovation the two are not alternatives — they are neighbours in the same sandwich. From the slab upward:

1. Structural concrete slab. The developer's floor. Never touched in a normal reno.
2. Cement screed, 20–50mm. Poured to correct level, fall and services routing. This is what makes a floor flat.
3. Primer and mesh. Bonding coat, plus fibreglass mesh where movement or grout lines need bridging.
4. Microcement, 2–3mm. Two to three hand-trowelled layers, each thinner than a coin.
5. Polyurethane sealer, 2 coats. The layer that actually resists water, stains and abrasion.

The practical consequence: screed problems become microcement problems. A screed with the wrong fall, trapped moisture or live cracking will telegraph straight through a 2mm finish, which is why we check substrate before quoting any floor.

"Screed floor" is usually one of three things

1. Raw cement screed. Industrial look, exposed substrate, sealed. Cheap, but greys aggressively and hairline-cracks.
2. Polished concrete. Mechanically ground and sealed. Much more expensive than screed; closer to microcement in finish but not the same.
3. Microcement floor. A 2–3mm decorative layer over screed. This is what most Singapore homeowners actually mean.

Durability and repair — the honest comparison

• Cracking. Raw screed cracks as a matter of course; it is a mass of cement drying against restraint. Microcement over a mesh layer resists hairline movement, but cannot bridge a live structural crack.
• Water. Unsealed screed absorbs and stains permanently. Sealed microcement sheds water, which is why it is specified in showers and splashbacks.
• Repairs. Screed is patched with more screed and never matches. Microcement is patched, feathered and the affected plane re-sealed so the finish reads continuous.
• Service life. Screed lasts as long as the slab. Microcement's life is governed by its sealer, refreshed every 4–6 years on hard-worked floors.

Timeline and disruption

A screed pour needs 24–48 hours before foot traffic and, as a rule of thumb, roughly one day of drying per millimetre before a moisture-sensitive finish can go over it — a 40mm screed can hold a project for weeks. Microcement over an existing cured screed is far quicker: 3–4 working days for a feature wall, around nine for a full-plaster bathroom, because each thin layer cures in hours rather than days.

When to choose which

If you like the look of grey, brutalist screed — you are usually looking at microcement on a feature wall, not raw screed on the floor. Raw screed is unforgiving in a humid HDB. For dry-area floors, the SPC microcement-vinyl plank gets you most of the aesthetic at a fraction of the cost and zero hairline cracks. For wet-area floors and bathroom walls, authentic plaster — see the microcement bathroom page.
