Painting an HDB flat: cost, prep and how many coats

Planning to repaint your flat and want to know what it'll cost before you commit? In Singapore, the painting HDB flat cost typically runs from about $450 for a whole 3-room unit to $1,500 or more for a 5-room or executive flat, covering walls and ceilings in two coats of standard emulsion. Per-room jobs usually start from around $120–$180 for a bedroom. What moves the price is flat size, ceiling height, the paint type, how much crack repair the walls need, and the amount of furniture to protect. This guide breaks down the HDB painting cost in Singapore, how many coats you actually need, which paint to use where, and whether to paint it yourself or hire.

How much does painting an HDB flat cost?

Painters in Singapore usually quote either by the whole unit or per room. Whole-unit pricing is the better deal per square metre because the painter sets up once and works through the flat in a single mobilisation. Per-room pricing suits you when only one or two spaces need a refresh. The table below shows typical 2026 market ranges for walls and ceilings in two coats of standard emulsion — treat them as indicative and always confirm a fixed quote after a look at your flat.

Flat type	Whole unit (SGD)	Per room (SGD)
3-room	$450 – $750	$120 – $180
4-room	$650 – $1,100	$130 – $200
5-room	$850 – $1,400	$140 – $220
Executive / maisonette	$1,100 – $1,800+	$150 – $250
Single room only	—	From $120

Whole-unit quotes usually assume standard emulsion in regular colours. Premium or designer paint, feature walls, very high ceilings, heavy crack repair and extensive furniture moving all push the figure up.

What affects the price

• Flat size and number of rooms — more wall and ceiling area means more paint and labour.
• Paint type — anti-mould, washable and premium emulsions cost more than standard wall paint.
• Condition of the walls — cracks, peeling paint, water stains and old dark colours all add prep time.
• Ceilings — including ceilings rather than walls only adds area and is often quoted separately.
• Colour change — going from a dark wall to white, or vice versa, may need an extra coat.
• Furniture and protection — an empty flat is quicker and cheaper to paint than a fully furnished one.

One coat, two coats, or primer?

This is where most quotes quietly differ, so it's worth understanding before you compare prices.

One coat

A single coat almost never gives an even result. It tends to look patchy, the old colour ghosts through, and the finish wears thin. One coat is really only acceptable as a light touch-up over the same colour on walls that are already in good shape.

Two coats

Two coats is the standard for a proper repaint. The first coat covers and the second evens out the colour and depth, giving a durable, uniform finish. When a painter quotes you, assume two coats unless they say otherwise — and if a quote looks unusually cheap, check whether it's only one.

Primer / sealer

A primer or sealer coat goes on before your colour coats in specific situations: bare plaster after crack repair, water or smoke stains that would bleed through, glossy or previously oil-painted surfaces, and big colour changes. Priming stops stains showing through and helps the topcoat grip and last longer.

Prep comes first: patching cracks and holes

The finish you end up with is decided before any colour goes on the wall. Skipping prep is the single most common reason a fresh repaint still looks tired. A proper job follows these steps:

1. Protect floors and furniture with dust sheets and masking, and tape off skirting, switches and door frames.
2. Scrape off any flaking or peeling paint and sand rough patches smooth.
3. Fill hairline cracks, nail holes and dents with filler, then sand flush once dry.
4. Spot-prime the patched areas and any stains so they don't ghost through the topcoat.
5. Wipe down dust, then apply two coats of emulsion with proper drying time between them.

Hairline cracks are normal in HDB flats as the building settles, especially around door frames and ceiling corners. Filling and spot-priming them is part of a tidy painting job — not an upsell.

Which paint for which room

Not every wall in your flat wants the same paint. A quick guide:

• Living room and bedrooms — standard interior wall emulsion is fine. A washable or low-sheen finish helps if you have young children or scuff-prone hallways.
• Kitchen and bathrooms — use an anti-mould or moisture-resistant emulsion. These areas get steam and condensation, and ordinary paint will mould and peel over time.
• Ceilings — a flat white ceiling paint hides imperfections better than wall emulsion; anti-mould ceiling paint suits kitchen and bathroom ceilings prone to damp.
• Feature walls — fine with a deeper colour, but expect it may need an extra coat to cover evenly.

Don't forget the ceiling

Ceilings are easy to leave out of a quote and then regret. A freshly painted wall against a yellowed or stained ceiling looks half-finished. If your ceilings are dingy, water-marked or it's been many years, include them — and confirm whether the quote you're comparing covers ceilings or walls only, because that single line is often why two quotes differ.

Furniture protection and drying time

For an occupied flat, the painter should sheet up and shift furniture to the centre of each room, then mask floors, skirting and fittings. An empty flat — common between move-out and move-in — is faster, cleaner and usually a little cheaper to paint.

On drying: standard emulsion is touch-dry within an hour or two and ready to recoat after about four hours, which is why two coats can be done in a day. It's best to leave walls overnight before pushing furniture back against them so the surface fully cures and doesn't scuff or stick. A whole-flat repaint is commonly completed in one to two days depending on size and how much prep the walls need.

DIY or hire a painter?

A single small bedroom in good condition is a reasonable weekend DIY if you don't mind the masking and the mess. Beyond that, the maths shifts: once you buy paint, rollers, trays, masking tape, dust sheets and a step ladder — and spend two days on it — a professional whole-unit quote often isn't far off, and the finish is cleaner.

Reasonable to DIY

• One small room, walls already in good condition
• A simple same-colour refresh with little patching
• Low, easy-to-reach ceilings

Worth hiring out

• A whole flat, or several rooms at once
• High ceilings, stairwells or maisonette voids that need scaffolding or tall ladders
• Walls needing real crack repair, stain sealing or a big colour change
• A move-in or move-out deadline where it simply has to be done quickly and cleanly

If you're repainting as part of a bigger renovation, it's worth seeing how painting fits the overall budget — our HDB renovation cost guide puts it in context. And if you're painting around a handover, line it up with your move-out cleaning checklist so the flat is dust-free before the brushes come out.

HDB rules worth knowing

Painting the inside of your flat doesn't need an HDB permit — interior repainting is everyday maintenance, not renovation works like hacking or flooring. Two things to keep in mind:

• External and common areas. You can't repaint the outside of your block or the corridor as you please — external facade colours are controlled. Check the rules on the HDB website before touching anything outside your front door.
• Noise and timing. If prep involves any drilling or sanding, keep it within HDB's permitted hours and avoid late evenings out of courtesy to neighbours.
