What finish level should you expect on walls?

Plasterboard finishing uses levels 1–5 under AS 2589 — most visible walls and ceilings are level 4, with level 5 for critical lighting. Confirm the finish level in the quote.

What goes wrong with plastering?

Visible joints, nail pops and uneven finish from rushed preparation or the wrong finish level. Agree the level and lighting conditions up front.

How do you vet a plasterer?

Hiring a Plasterer
is buying
the finish level.

Plastering work isn't graded on look — it's graded on a number. AS 2589 sets the standard: Level 3 is fine for textured ceilings, Level 4 is standard residential walls, Level 5 is what you need for low-sheen + gloss paints + raking light. The cheap plasterer quotes Level 3 + leaves a Level 4 walls problem for the painter to discover.

Standard finish level for residential walls.

Required for gloss / low-sheen / raking light.

AS 2589

The Australian Standard. The grade is in there.

Before we start

The plaster is the canvas.
The finish level decides what paint hides.

Plastering quality has three invisible variables: how flat the sheets sit on the frame, how well the joins are taped + set, and how aggressively the surface is sanded after the final skim coat. The cheap plasterer skimps on the third — and you wear the consequence the moment you choose anything other than matte paint.

The 10 questions below force the finish level into the conversation before quote. A working plasterer asks what paint you're using before quoting. A high-risk operator quotes "standard" without asking.

If they don't ask what paint sheen you're using, they're not quoting a finish level — they're quoting the cheapest one.

How much should it really cost?

Plasterboard is priced per m² installed. Solid render is priced per m² applied. The finish level is the major price variable — Level 5 typically 20–30% more than Level 4.

Indicative ranges · AU 2026

Plasterboard (supply + install · L4)	$55 – $95/m²
Plasterboard (L5 finish)	$75 – $130/m²
Solid render (cement on brick)	$60 – $110/m²
Ceiling patch / repair	$280 – $850
Cornice (per linear m)	$22 – $48/m

Ask this, exactly

"What AS 2589 finish level are you quoting, and what paint sheen does it suit?"

How to tell a real one from a cowboy.

Red flags

!
No mention of AS 2589 finish level
"Standard finish" means whatever they feel like. The standard is Level 4 for typical residential walls; the quote-trap operator means Level 3.
!
No coordination with painter
Working plasterers ask which paint sheen you're using before quoting. Gloss paint + Level 4 finish = visible joins. Corner-cutter doesn't ask.
!
Light sand only
L5 = full sand + extra skim coat + dust-free finish. Cheap plasterers skip the extra coat + the proper sand. Lumps + paper edges show through paint.
!
Cash payment
No invoice, no warranty, no ABN trail. Standard red-flag operator pattern.
!
No mention of cure time before paint
Set compound needs 24–48 hours dry before painting. High-risk operators rush handover; paint over wet set = blotchy paint + adhesion failure.

Finish levels — AS 2589.

L3Textured

Level 3

Joints taped + set. One coat compound.
Suitable only for textured / sprayed ceilings, heavy wallpapers.
Quote-trap operators quote this for walls + pretend it's standard.

L4Standard wall

Level 4

Two coats compound + sand. Flat finish.
Standard for matte / low-sheen wall paint.
Industry-standard residential finish.

L5Premium

Level 5

L4 + skim coat over entire surface + full sand.
Required for gloss, low-sheen, raking light, dark colours.
20–30% more than L4. Worth it where paint sheen is high.

Half-time

The paint sheen decides the finish level.

Quote anatomy, the cowboy test, the finish level. The first three sort the working plasterers from the ones who quote standard + leave the problem for the painter. The next seven are how working plasterers tell themselves apart.

When can they fit you in?

Plasterers 3–8 weeks out for standalone jobs. Renovation contexts often see plasterer book inside the builder's overall schedule. Set compound needs 24–48 hours cure before painter starts.

Ask this, exactly

"What's your earliest slot + what's the cure window before the painter can start?"

Plasterboard

Fixed to timber or steel framing. Joints taped + set. Modern standard for internal walls + ceilings.

Right when: new build, renovation, retrofit. Vast majority of residential work.

Option B

Solid render

Cement render applied directly to brick / block. Used externally + internally on old houses. Specialist sub-trade.

Right when: external walls, brick retrofit, heritage match.

Option C

Patch / repair

Ceiling patch, wall hole repair, cornice replacement. Smaller jobs. Half-day to full-day work.

Right when: small damage, leak repair finish, post-electrical patching.

Warranty — workmanship + product.

Layer 01
Statutory structural
6 years (NSW · VIC) / 6.5 years (QLD) on structural plastering work above threshold.
Layer 02
Workmanship
Typically 12 months. Joint cracking, sheet popping, finish defects.
Layer 03
Sheet manufacturer
CSR Gyprock / Boral / Knauf — 10+ years on the sheet itself.
Layer 04
Settling cracks
Hairline cracks at first-year settling are not workmanship defects — they're expected. Working plasterer touches up for free in first 12 months.

Ask this, exactly

"What's your workmanship warranty + your rule on settling cracks in the first year?"

Old houses, lath + plaster.

Pre-1960 lath + plaster
Wood lath + lime plaster underneath. Specialist trade for repair or sympathetic replacement.
Pre-1990 asbestos wall sheeting
Removal is licensed work. Cannot be cut / sanded / drilled by a standard plasterer.
Heritage cornice + ceiling rose
Specialist sub-trade. Casting replicas from existing originals. Original lime plaster repair.
Wet area plasterboard
Moisture-resistant board (green) required in bathrooms + laundries. Tiler verifies before tiling.

Ask this, exactly

"Have you done lath-and-plaster / heritage / wet-area work — and what's the rule if we find asbestos in the demo?"

Edge cases — get a second opinion for…

Pre-1990 asbestos sheet
Cannot be cut / sanded / drilled. Licensed asbestos removal first.
Heritage / lime plaster
Specialist heritage plasterer. Lime mix + lath repair. Don't use a standard board plasterer.
Decorative cornice + ceiling rose

Curved walls
Bendable plasterboard (12.5mm) or specialty curved sheet. Specialist install.
Strata common-property repair
OC approval. Common-property ceiling / wall repair after upstairs leak.
Render over painted brick
Surface preparation critical. Cheap render-over-paint = peeling render in 18 months.

After they leave.

Wait 24–48 hours before painting. Expect hairline settling cracks in the first 12 months — these are normal, not a defect. A working plasterer comes back at the 6-month mark to touch up.

Ask this, exactly

"When can the painter start, and will you come back at 6 months to touch up any settling cracks?"

If you've read this far

A plasterer who asks what paint sheen you're using before quoting the finish is not a unicorn. It's the bar.

53 homeowner quotes · Reg State trade regulator + work-safety regulator · AS AS 2589 · 9 operator quotes · Last reviewed June 2026

Quote anatomy

What a real quote should contain

Operator + ABN

Full legal name + active 11-digit ABN

Verify on the Australian Business Register before paying any deposit. If the ABN isn't active, the contract has no enforceable counterparty.

State trade licence

Licence number + class on the quote

Cross-check on the relevant state regulator (linked in the glossary licence-check section). Confirms they can legally do the work.

Public liability insurance

$10–20 million cover, still current (not expired)

This is what pays if they damage your home — or a neighbour's — or someone is injured during the job. Ask them to email you the insurance certificate; "I'm covered, mate" is not proof.

Workers' insurance

In place if they bring any workers onto your property

If a worker is hurt on your property and the operator has no workers' insurance, you can be the one left liable. A genuine sole trader with no employees may not need it — just ask.

Itemised scope of work

What's included, what's not, line by line

"Standard installation" means nothing in court. Specific scope items are what get enforced.

Materials specification

Brand, grade, quantity, AS standard where applicable

Prevents the "we used what was on the truck" substitution that turns up under failure inspections.

Variations clause

How changes get priced + agreed, in writing

No written variation = unenforceable. Verbal "we'll work it out" is how budgets blow out by 40%.

Deposit + progress

Within your state's legal cap (e.g. NSW 10%; VIC 10%/5% by threshold; QLD tiered 20%/10%/5% by job value)

Above-cap deposits are illegal. Caps differ by state — check your state's current regulator guidance. Progress payments should align with completed stages, not arbitrary dates.

Warranty terms

Workmanship period + manufacturer warranty pass-through

Statutory warranty applies regardless, but written terms accelerate enforcement.

Completion definition

What "practical completion" means for this job

Triggers final payment + starts the defects liability period.

Dispute path

Named regulator/tribunal for disputes (e.g. NCAT, VCAT, QCAT)

Knowing the path before signing makes you a less attractive target for a dispute.

If a quote you receive is missing any of these, ask for them before you sign or pay a deposit.
