Painter on a residential job: scope, licensing, finishes, tolerances

TL;DR

The painter is the last trade through a residential job before handover: surface prep, prime, and two-coat finish to walls, ceilings, trims, and externals. AS/NZS 2311:2017 is the referenced practice standard for painting buildings. Licensing is uneven: NSW requires a contractor licence for residential painting over $5,000 (exemption: stand-alone internal painting contracts don’t need one unless bundled with other home building work); VIC does not require registration for painting-only work; QLD requires a QBCC Painting and Decorating licence for work over $3,300. The biggest programme kill is scheduling the painter before the plasterer has finished and sanding is complete: paint over dust or unset compound produces callbacks. Day rates for residential painting typically run $50 to $90/hr ex-GST; m² rates vary widely with surface type and coat count.

What this trade covers

The residential painter applies decorative and protective coatings to interior and exterior surfaces. On a typical new build, they are the second-last or last trade through before the PCI.

Interior: walls, ceilings, cornices, skirtings, architraves, doors, window reveals. Surfaces are primed and top-coated to the specified finish (flat, low-sheen, semi-gloss, or gloss).

Exterior: external walls, fascias, barges, soffits, eaves, timber weatherboards, window and door frames. External coatings are subject to UV, moisture, and temperature cycling; product selection and prep are critical.

Specialty: two-pack epoxy floors, feature wall finishes (limewash, Venetian plaster), texture coatings to masonry, and anti-graffiti coatings on commercial fringes of residential work.

What’s in scope (typical residential)

Surface preparation: fill, sand, and prime all surfaces before top-coating
Prime all bare timber, masonry, and plasterboard prior to finishing coats
Two-coat finish to interior walls and ceilings
Semi-gloss or gloss finish to skirtings, architraves, door jambs, and doors
External walls and trims (fascias, soffits, barges, weatherboards) to the specified coat system
Touch-up and make-good of minor surface defects identified during prep
Clean-up of paint drips, overspray, and masking residue after each phase

What’s out of scope (often confused)

Plasterboard fixing, taping, and setting: the plasterer’s scope. Paint over poorly-set joints produces callbacks; the painter must not be on site until setting and sanding are done.
Waterproofing membranes: separate trade. A painter may apply a texture coat or masonry sealer over a substrate, but wet-area membranes under tiles are the waterproofer’s scope.
Staining and sealing timber floors: sometimes painter scope, sometimes a specialist floor finisher. Confirm in the scope of works.
Wallpaper and wall coverings: separate trade or a specialist painter. Not all painters quote for it.
Lead paint removal and disposal: regulated separately. If lead paint is confirmed on pre-1970 surfaces, assess whether the scope extends to safe removal. Confirm written authority and disposal method before starting.

The scope of works should state the coat system (product, sheen, number of coats) and who supplies paint. Most painting variations originate from scope creep on ceiling heights, additional coats on feature walls, or substrate condition at handover from the plasterer.

Engagement basics

Licensing, state-by-state

State	Scheme	Key rule
NSW	NSW Fair Trading contractor licence	Required for residential building work (including painting) valued over $5,000 in labour and materials (including GST). Exception: stand-alone contracts for internal painting work do not need a licence, unless that painting is part of other home building work. Qualification: CPC30620 Certificate III in Painting and Decorating (or equivalent). Penalties: $22,000 individual / $110,000 company under the Home Building Act 1989 (NSW) (verified 2026-05-10).
VIC	Building and Plumbing Commission (formerly VBA)	Painting-only work does not require registration in Victoria, regardless of dollar value, as painting is excluded from the definition of domestic building work when performed as a single trade task. Registration is required only where painting is carried out alongside other classes of domestic building work where the combined value exceeds $10,000. Verify current rules with the Building and Plumbing Commission (verified 2026-05-10; VBA transitioned to Building and Plumbing Commission July 2025).
QLD	QBCC Painting and Decorating licence	Required for residential painting work where the total value of building work exceeds $3,300 (labour and materials). Qualification: CPC30620 Certificate III in Painting and Decorating; managerial qualification (BSBESB402) required for contractor licence. See QBCC Painting and decorating (verified 2026-05-10).
WA, SA, TAS, NT, ACT	Each state has its own scheme	Verify current licence class, insurance requirements, and threshold with the state regulator before quoting.

Unlicensed work in NSW carries real penalties. Even for internal painting under the standalone exemption, confirm whether the contract also includes any other home building work, which would negate the exemption.

Apprenticeship pathway

Painters typically complete a CPC30620 Certificate III in Painting and Decorating (current qualification, supersedes CPC30611) through a TAFE or registered training organisation (RTO), usually via a 3 to 4 year apprenticeship combining on-the-tools work with block-release study (verified 2026-05-10).

Insurance the painter should carry

Public Liability: typical floor $5m for sole-trader residential, $10m when working under a head contractor
Workers Compensation: required for any employees or apprentices
Tool and plant insurance: not contractually required but standard for painters with significant plant (spray equipment, scissor lift)

Current Certificates of Currency for PL and Workers Comp should be sighted before any work starts. The painter holds them; the engaging party (usually the builder, sometimes the client direct) confirms them.

Pricing basis

Residential painting is commonly priced as:

m² rate: for well-defined scopes (new builds, uniform substrates). Rate varies by coat count, surface type, and ceiling height. Typical range $8 to $20/m² ex-GST for a standard two-coat interior finish; add for three-coat, high ceilings, or feature walls.
Day rate: $50 to $90/hr ex-GST (or $400 to $750/day ex-GST). Suits renovations, patch work, mixed substrates, or tight-access areas.
Lump sum: common on well-documented new builds.

Confirm whether the rate covers paint supply or labour-only. Most disputes on painting packages start from unclear supply boundaries or additional coats on substrates in worse condition than expected.

Tolerances and acceptance

Painter work is judged at PCI against the contract spec, AS/NZS 2311:2017 (the practice standard for painting buildings), and the HIA Guide to Materials and Workmanship plus the relevant state Guide to Standards and Tolerances.

AS/NZS 2311:2017

AS/NZS 2311:2017 (incorporating Amendment No. 1, 2019) is the recognised Australian practice standard for painting of buildings. It covers surface preparation, priming, coat systems, product selection, and application requirements for residential and commercial work (verified 2026-05-10). It does not set workmanship tolerances in the same numerical way as a construction standard: for tolerance values at PCI, the HIA Guide is the primary reference.

Workmanship tolerances (HIA pending)

Numerical PCI limits for paint finish quality are set by the HIA Guide to Materials and Workmanship and the relevant state Guide to Standards and Tolerances. Values are pending HIA member access.

Item	Guide coverage
Paint film flatness, bowing or ripple visible in raking light	Per current HIA Guide to Materials and Workmanship and state Guide. Pending HIA member access. [HIA-130]
Brush or roller marks, texture variation across a wall face	Per HIA Guide and state Guide. Pending HIA member access. [HIA-131]
Paint finish sheen consistency (gloss variation, sheen banding)	Per HIA Guide and state Guide. Pending HIA member access. [HIA-132]

What can be assessed independently

Coverage: a single-coat finish that misses spots (holidays) or shows substrate bleed-through is a preparation or coat-count failure. Visible under raking light.
Overspray and paint runs: drips and runs from incorrect application technique or wrong viscosity. Checked on trim and door surfaces under direct light.
Masking and cut-in: paint on glass, hardware, tile faces, or plumbing trim is a workmanship defect. Cut-in line straightness at wall-to-ceiling junctions is assessed visually.
External coat adhesion: adhesion failures (peeling, flaking) within the defects liability period from inadequate prep (dirty or damp substrate) are a contractor defect.

Common defects to look for

What inspectors and clients flag at PCI for painter work:

Holidays (missed spots): areas of substrate or primer showing through the finished coat. Common on ceilings in low-contrast colours or at cornice returns. Best caught with a raking light.
Paint runs and drips: brush loading errors or spray viscosity wrong. Common on skirtings, door faces, and window reveals.
Sheen banding: lap marks visible where wet edge was lost mid-wall, producing a shinier strip. More common with low-sheen products on large walls.
Paint on glass, hardware, tiles: masking pulled too early, or no masking. Clean-up after painting is supposed to remove it; if it’s cured, it’s a defect.
Poor cut-in at cornice: wavy line where wall meets ceiling, or ceiling colour bleeding onto the wall. Very visible in raking light.
Substrate telegraphing: plasterboard joint lines, fastener pops, or cornice joints visible through the paint film. Usually a plasterer-surface issue, but painter responsibility to flag before proceeding.
Exterior coating failure on timber: peeling within the defects liability period from wet timber at time of application, or insufficient coat count on bare end grain.
Lead paint disturbed without controls: on pre-1970 residential renovations, paint disturbance without appropriate WHS controls is a safety defect and a regulatory breach.

Most paint defects on new builds are caught at the pre-PCI painter’s own inspection, then at the PCI walkthrough. Defects found after handover (sheen banding in raking light, holidays on ceilings) can be costly to remediate because areas must be repainted top-to-bottom rather than touched-up.

Health and safety

Painting carries two priority WHS hazards on residential jobs.

Lead paint (renovation and alteration work): Lead-based paint was common on pre-1970 Australian homes. Sanding, scraping, or heat-stripping lead-painted surfaces without controls generates lead dust, which is a lead process under WHS Regulations. Controls include: wet methods (wet sanding, wet scraping), HEPA-filtered vacuum extraction, P2 minimum respirator during disturbance, containment sheeting, and regulated lead dust disposal. The relevant guidance standard is AS/NZS 4361.2:2017, Guide to lead paint management (verified 2026-05-10). Exposure standard for inorganic lead is set by Safe Work Australia in the Workplace Exposure Standards. For pre-1970 renovation work, assess lead paint presence before quoting.

Solvents and isocyanates (two-pack products): Two-pack polyurethane and epoxy coatings used on floors, joinery, and metal generate isocyanate vapours. Controls: adequate ventilation, organic vapour respirator (not a dust mask), no spraying without specialist PPE. Solvent-based products on enclosed spaces have ignition risk from residual vapour.

Manual handling and working at heights (stilts, ladders, platforms) apply on most residential painting packages.

Subbie quote pack, what should be in it

A complete painter quote pack covers:

Scope: which surfaces (interior walls, ceilings, trims, externals), which areas are explicitly excluded, and what the paint system is (product, sheen, number of coats per surface type)
Paint supply: who supplies paint and whether the rate is labour-only or labour-plus-materials; confirm product brand and sheen level
Pricing basis: m² rate, day rate, or lump sum; variation rate stated for unscoped work (e.g. additional coats, high-ceiling penalties, feature wall treatments)
Substrate condition: explicit statement of substrate condition assumed (e.g. Level 4 plasterboard finish, new timber primed, masonry block-filled). Variation mechanism if substrate arrives in worse condition.
Programme: days on site per phase (prime, first coat, second coat), sequencing dependencies (plasterer sanding done, wet areas complete and cured, hardware not installed)
Licence and insurance: contractor licence number (where required), Certificates of Currency for PL and Workers Comp
Lead paint clause (renovations): whether lead paint assessment is in or out of scope; if in, what the response protocol is
Clean-up: who removes masking, drops sheets, and paint waste; clean-up after each phase vs once at end
Variation mechanism: written authorisation required; day rate for unscoped work stated

The same list reads from different sides: the engaging party uses it as the quote template; the painter providing all of it unprompted wins more jobs; the client uses it as the bar the builder should be applying.
