How Often Should a Commercial Building Be Repainted in Melbourne? Answers to the Questions Owners and Facility Managers Ask Most
The short answer: most commercial buildings in Melbourne need a full external repaint every 7 to 12 years. Timber, high-wear interiors and exposed steel need attention sooner. The real interval depends on the substrate, the coating system originally specified, how exposed each elevation is, and whether the building has been maintained between repaints. A condition-based programme almost always beats a fixed calendar date.
If you manage a warehouse in Laverton, a strata complex in Box Hill or a retail centre in the south-east, you have probably received conflicting advice on this. Here is how we answer it on site.
How long does commercial paint last in Melbourne?
The table below shows indicative repaint intervals for a correctly specified and applied system with routine maintenance. Poor preparation or the wrong product can halve these figures.
Surface | Typical external repaint interval | Notes |
Rendered masonry and precast concrete | 8 to 12 years | Elastomeric systems bridge hairline cracking and extend life |
Fibre cement cladding and fascias | 7 to 10 years | Joint and edge failure usually shows first |
Timber (cladding, soffits, trims) | 4 to 7 years | Most vulnerable to moisture and UV |
Structural and architectural steel | 5 to 10 years for touch-up cycles | Depends heavily on the protective system and exposure |
High-traffic interiors (corridors, lobbies, amenities) | 3 to 5 years | Impact and cleaning wear drive the cycle |
Low-traffic interiors (offices, meeting rooms) | 7 to 10 years | Often repainted earlier for tenancy changes or rebrands |
North and west-facing elevations take the most UV and usually fail first. That's why many of our Melbourne programmes stage elevations rather than repainting a whole building at once.
Why does Melbourne weather shorten paint life?
Melbourne can swing 15 degrees or more in a day. That repeated heating and cooling makes substrates expand and contract, which opens hairline cracks in render and stresses paint films at joints. Add winter moisture, summer UV, and salt air in bayside suburbs such as St Kilda, Williamstown and Frankston, and coatings are under constant load. In the industrial west and north, airborne pollutants and dust add to the wear. We cover the technical side of this in Structural Preservation for Victoria's Commercial Assets.
What are the signs a building needs repainting?
Watch for these warning signs:
Chalking: a powdery residue that comes off on your hand, which means the binder is breaking down.
Fading and colour drift: especially on brand colours and north-facing walls.
Cracking, flaking or peeling: the coating has lost adhesion or flexibility.
Bubbling or blistering: usually moisture behind the film (see our guide to bubbling paint).
Rust staining: corrosion bleeding through from fixings or steel.
Efflorescence: white salt deposits on masonry, a sign of moisture movement.
Mould and dark staining: common on shaded southern elevations.
One or two of these in isolated spots usually calls for targeted repairs. Several of them across an elevation usually means the system has reached the end of its life.
Do I need a full repaint, a maintenance coat or touch-ups?
It depends on the condition of the existing coating.
Touch-ups suit localised damage on an otherwise sound system: impact marks, graffiti removal, small areas of flaking.
A maintenance coat suits a coating that is faded or chalking but still well adhered. After cleaning and light preparation, a single topcoat can reset the clock at a fraction of the cost of a full repaint.
A full repaint is needed once adhesion has failed across large areas, or when the substrate needs repair first.
The window for a maintenance coat is the one most owners miss. Wait too long and a one-coat job becomes a strip, repair and three-coat job. A coating condition assessment tells you which side of that line you are on. ATD's CASA-certified drone inspections let us assess façades and roofs without scaffold or access equipment.
How much does a commercial repaint cost in Melbourne?
Online price guides for Melbourne commercial painting vary enormously, because no two buildings are alike. The main cost drivers are:
Surface preparation: washing, crack repair, rust treatment and removal of failed coatings often cost more than the paint itself.
Access: EWPs, scaffold, swing stages or rope access, plus traffic and pedestrian management.
Coating system: standard acrylics cost less than elastomeric, anti-carbonation or two-pack protective systems.
Operating hours: after-hours, weekend or staged work around a live site adds labour loadings.
Colour changes and rebrands: extra coats and more detailed cut-in work.
Condition at the time of work: deferred maintenance is the single biggest avoidable cost.
The cheapest quote is rarely the cheapest outcome. Compare quotes line by line on preparation and product specification. Our four questions to ask before hiring a commercial painting contractor shows you how.
When is the best time of year to paint exteriors in Melbourne?
Autumn and spring usually give the most reliable application windows. Most exterior coatings set a minimum application temperature, commonly around 10°C, and must be applied above the dew point so moisture does not form on the surface. Winter brings short days, cold mornings and lingering damp. Summer brings extreme surface temperatures that make paint dry too fast. Good contractors programme around the weather and use the downtime for preparation rather than forcing coatings onto unsuitable surfaces.
Does our owners corporation need to plan for repainting?
External painting is one of the largest capital items in most Victorian strata budgets. Under the Owners Corporations Act 2006, tier one and tier two owners corporations must have a 10-year maintenance plan and a maintenance fund. Smaller owners corporations are not legally required to have one, but Consumer Affairs Victoria recommends it.
The plan must record the current condition of major items, when they will need work, the estimated cost and the expected life once repaired. That is exactly what a coating condition report gives your committee. A realistic repaint cycle in the plan is the best defence against a surprise special levy.

Can we keep trading while the building is painted?
Yes. Most of our Melbourne commercial work happens in occupied, operating sites. Staging zones, out-of-hours work in customer areas, low-odour products and clear site communication let shops, warehouses, schools and healthcare facilities keep running. Our IKEA Richmond façade repaint, covering more than 15,000 m², was delivered while the store stayed open.
What about older Melbourne buildings and lead paint?
Many of Melbourne's older commercial and heritage buildings still carry lead-based paint under later coats. Before any sanding or stripping on older buildings, the existing paint should be tested. Where lead is present, preparation must follow safe removal and containment practices to protect workers, occupants and the surrounding area.
How a planned maintenance programme changes the maths
Reactive repainting is expensive because problems are usually found late. A planned programme runs on scheduled inspections, early touch-ups, maintenance coats at the right time and elevation-by-elevation staging. It spreads cost evenly across budget years, extends the life of each coating system, and keeps your building presenting well between full repaints. See how our planned maintenance programs work.
