Key takeaways
- Most plastering jobs in Singapore land between SGD 150–SGD 4,000 — known locally as skim coating and cement plastering.
- Renovation in HDB flats must use HDB-registered contractors, and spalling-concrete ceiling repair in older flats is a recognized maintenance issue (HDB provides guidance and shares costs in some cases). Skim coating whole flats before painting is a standard, competitively priced package in Singapore.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Singapore typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a plastering pro in Singapore
- For HDB flats, use an HDB-registered renovation contractor
- Ask for skim coat pricing per room or per whole flat — Singapore contractors usually quote flat packages
- Confirm the quote includes sealing hairline cracks and popped nail/screw spots
- Check spalling concrete (exposed rusty rebar on ceilings) is quoted as a separate repair — it is not a skim job
- Agree noisy-work hours per HDB/condo rules
- Compare packages on Qanvast or HomeRenoGuru
Red flags
- Skim coating over spalling concrete without treating the rebar
- Not HDB-registered for flat works
- Whole-flat package that excludes ceilings without saying so
- Large upfront payment
- No warranty on peeling or hairline crack return

Frequently asked questions
Why is my new plaster cracking?
Fine crazing usually means the plaster dried too fast (heat, draughts) and is cosmetic — fill and paint. Straight-line cracks along boards or above doors indicate movement at joints. Wide or recurring cracks are worth a builder's inspection before redecorating.
Is plastering messy? How do I prepare the room?
It is one of the messiest trades — expect splatter, dust and high humidity. Empty the room if possible, or centre furniture under sheeting. Floors should be fully covered. Ask whether the quote includes protecting surfaces and cleaning up.
What is rendering versus plastering?
Rendering is exterior plastering with cement- or silicone-based mixes to protect and finish outside walls; plastering refers to interior walls with gypsum or cement finishes. Many plasterers do both, but exterior render is priced and scheduled differently (weather-dependent).
Can plastering fix damp walls?
No — plaster over damp fails within months. The moisture source (rising damp, leaking gutter, condensation) must be fixed first, then damaged plaster cut back and replaced, sometimes with a salt-resistant renovation plaster. Any plasterer who skips the cause is selling you a repeat job.
How much does plastering cost?
Plastering is usually priced per square metre or per room. A skim coat over existing sound walls is the cheapest job; full re-plastering (hacking off old plaster and applying new base and finish coats) costs two to three times more, and exterior rendering is priced separately.
What is the difference between skimming and full plastering?
Skimming is a thin 2-3 mm finish coat applied over existing plaster or plasterboard to give a smooth paintable surface. Full plastering means building up base (browning/bonding) coats plus a finish coat, needed when old plaster is blown, damp-damaged or removed back to brick.
What is spalling concrete and why can't it just be plastered over?
Spalling is concrete cover breaking off ceilings as embedded steel rusts — common in older Singapore flats' bathrooms. Proper repair treats and seals the rebar and patches with mortar; plastering over it hides active corrosion that will pop the new finish off.
