Wall cladding is something most homeowners have but not everyone knows much about. It’s the outer layer on your home’s exterior walls, and it does more than just determine how your place looks from the street. It protects your structure from the weather, contributes to insulation, and plays a big role in how much maintenance your home needs over time.
Whether you’re trying to identify what type of cladding your home has, thinking about painting it, or wondering what a repaint might cost, this guide covers everything.

What Is Wall Cladding?
Wall cladding is a material applied to the outside surface of a building’s walls. It’s not the structural wall itself. It’s a protective and decorative layer fixed over the framing or masonry that makes up the actual structure of the building.
Cladding serves several functions at once:
- Weather resistance – keeps rain, wind, and moisture from penetrating the wall structure
- Thermal performance – adds an insulating layer that helps with energy efficiency
- Aesthetics – defines the character and style of the home’s exterior
- Structural protection – shields the framing from UV, moisture, and physical damage
In Melbourne, you’ll see a wide variety of cladding across different suburbs and housing eras. Inner-city and older homes often have original weatherboard or brick. Homes built from the 1980s onward frequently have fibre cement or rendered brick veneer. Newer builds often use a mix of materials.
Understanding what type of cladding your home has matters because different materials need different prep, different primers, and different paint systems.
Common Types of Exterior Wall Cladding
Weatherboard / Timber
Weatherboard is a classic Australian cladding style. Horizontal timber boards that overlap slightly, shedding water away from the wall. It’s been used for over a century and still looks great on Victorian, Edwardian, and Federation-era homes.
Advantages of weatherboard:
- Timeless aesthetic that suits many architectural styles
- Can be painted and repainted in any colour
- Natural material that ages well when maintained
- Repairable: individual boards can be replaced if damaged
Things to consider:
- Requires regular painting every five to ten years to stay protected
- Susceptible to moisture damage and rot if paint is allowed to fail
- Some risk of termite damage in certain areas
Melbourne’s inner and middle suburban streets are full of weatherboard homes. Many still have original boards in good structural condition that simply need thorough prep and a quality repaint to look their best.
Fibre Cement (e.g. James Hardie)
Fibre cement cladding, with James Hardie being the dominant brand in Australia, has become one of the most popular exterior cladding options over the past few decades. It’s made from compressed cement, sand, and cellulose fibres.
Advantages of fibre cement:
- Low maintenance compared to timber
- Naturally resistant to fire and termites
- Dimensionally stable in Australian heat and humidity
- Available in many profiles to suit different architectural styles (weatherboard profile, shiplap, panel, and others)
Things to consider:
- Heavier than timber, which can affect installation costs
- Requires specific alkali-resistant primers
- Can crack at joints if not installed correctly or if the building moves
Most fibre cement products come pre-primed from the manufacturer. They still need a quality exterior paint system applied and maintained over time to protect the material and keep water out of joints and cut edges.
Metal and Colorbond
Metal cladding, including Colorbond steel products and aluminium composite panels, is common in contemporary homes and commercial buildings. Colorbond is the dominant product in residential use and is extremely well suited to Australian conditions.
Advantages of metal cladding:
- Very long service life with minimal maintenance
- Colorbond coatings carry long fade warranties (up to 36 years on some products)
- Excellent resistance to weather, fire, and pests
- Lightweight and fast to install
Things to consider:
- Can dent from impact
- Changing the colour requires specialist primers and coatings
- Higher upfront cost compared to some alternatives
Colorbond typically doesn’t need repainting for many years. When it does, the process requires a specialist primer formulated for pre-painted steel. Standard exterior acrylic will not bond adequately without it.
Brick and Render
Brick veneer is one of the most common exterior wall types in Melbourne’s middle and outer suburbs, particularly in homes built between the 1970s and 2000s. Render, which is a coating of cement or acrylic applied over masonry or lightweight framing, is popular for achieving a smooth, contemporary finish.
Advantages:
- Durable and very low maintenance once sealed and in good condition
- Brick provides excellent thermal mass, which helps moderate indoor temperatures
- Both can be painted and the colour refreshed as trends change
- Render in particular gives a clean, modern aesthetic
Things to consider:
- Render can crack over time and needs filling before repainting
- Painting brick is a long-term commitment as removal is very difficult
- Brick and render surfaces can develop mould or algae growth in shaded areas
Rendered homes that are painted regularly and sealed properly look consistently sharp. See our exterior cladding painting service for what’s involved in keeping them that way.
Cladding vs Render vs Painting: What’s the Difference?
These three terms get used interchangeably sometimes and it creates confusion. Here’s the distinction:
| Feature | Cladding | Render | Painting |
| What it is | Physical boards or panels fixed to the wall | A coating applied directly to masonry or framing | A decorative and protective coat applied to the surface |
| Primary purpose | Structural protection and weather resistance | Smooth surface finish and weather barrier | Colour, UV protection, and sealing |
| Can it be painted? | Yes, most types can | Yes | It is the painting |
| Typical cost | Medium to high upfront | Medium | Low to medium |
| Maintenance frequency | Varies by material | Repaint every 8 to 15 years | Every 5 to 10 years depending on exposure |
In most homes, cladding and render are what the wall is made of or covered with. Paint is the protective and decorative layer on top of both.
Can You Paint Wall Cladding?
Yes. Most types of exterior wall cladding can be painted. The key is using the right product for the specific material and doing thorough preparation beforehand.
Painting Fibre Cement and Weatherboard
Both fibre cement and timber weatherboard are regularly painted and respond well to quality exterior paint systems. They should be repainted every five to ten years to maintain protection.
For fibre cement:
- Use an alkali-resistant primer to prevent reaction between the cement and the paint
- Apply two coats of a quality exterior acrylic topcoat
- Pay particular attention to joints, edges, and any cut or exposed faces
For weatherboard:
- Sand and repair any splits, raised grain, or damaged areas first
- Use an exterior wood primer on any bare timber
- Apply two coats of quality exterior acrylic; some older homes benefit from a full prime coat before the topcoats
If the existing paint is peeling or chalking badly, strip or sand it back before recoating. Painting over a failing paint system just delays and worsens the failure.
Best Paints and Coatings for Cladding
What to look for when choosing a product:
- Acrylic exterior paint is the standard and best-suited choice for most cladding types. It’s flexible, UV-stable, and breathable. Well-known Australian brands like Dulux Weathershield, Taubmans Endure Exterior, and Solver Exterior all perform well.
- Elastomeric coatings are suitable for render and masonry surfaces. They’re slightly flexible and designed to bridge hairline cracks rather than cracking with the surface underneath.
- Specialty metal primers and topcoats are needed for Colorbond and aluminium. Standard acrylic will not adhere to pre-painted steel without the appropriate primer first.
- Intumescent coatings are required on cladding in Bushfire Attack Level (BAL) rated zones. This is specific to the fire rating requirements of the property.
Always check the paint manufacturer’s product data sheet to confirm the coating is suitable for your specific cladding material before purchasing.
How to Maintain and Repaint Cladding
Good maintenance extends the life of cladding and keeps repainting costs lower over time. Here’s what a simple maintenance routine looks like:
- Wash annually. A low-pressure hose or a soft brush with a mild detergent solution removes dirt, mould, and algae before they build up and accelerate surface degradation.
- Inspect for damage every year. Check for cracks, splits, loose boards, areas where caulk has failed around windows and doors, and any visible paint failure.
- Caulk gaps and joints. Use a quality exterior paintable caulk on any gaps or failed sealant. Water getting behind cladding through unsealed joints is a major cause of damage over time.
- Recoat while the paint is still in reasonable condition. Waiting until paint is peeling means more prep work, more cost, and a longer time for the substrate to have been exposed. Repainting at seven to ten years, before failure, is almost always more cost-effective.
- Use quality products. Budget exterior paint fades and chalks faster, meaning you’re back to repainting sooner. Quality paint applied correctly lasts longer and costs less over time.
Signs Your Cladding Needs Repainting or Repair
Watch for these warning signs:
- Chalking – the paint feels powdery when you run your hand over it
- Fading – the colour looks noticeably washed out compared to areas sheltered from the sun
- Peeling or flaking – paint is lifting from the surface in sheets or small chips
- Cracking – hairline cracks in render or splits appearing in timber boards
- Mould or algae growth – green or black patches, especially on south-facing or shaded walls
- Failed caulk – visible gaps around windows, doors, or panel joins
- Soft or spongy areas – pressing on timber cladding and feeling give rather than firmness is a sign of rot underneath
If you’re seeing two or more of these issues, it’s time to get the exterior assessed and quoted.
How Much Does It Cost to Paint Cladding in Melbourne?
Costs vary based on the size of the home, the type and condition of the cladding, access requirements (single storey vs two storey with scaffolding), and how much preparation is needed.
Here’s a rough guide for Melbourne:
| Scenario | Approximate Cost Range |
| Single-storey weatherboard repaint | $3,500 to $7,000 |
| Single-storey fibre cement repaint | $3,000 to $6,500 |
| Two-storey weatherboard or fibre cement | $6,000 to $14,000 |
| Single-storey render repaint | $2,500 to $5,500 |
These figures are estimates only. The actual cost on any specific home depends heavily on the level of preparation needed. Homes with significant peeling, timber rot, complex architectural details, or difficult access will sit at the higher end of these ranges.
For an accurate figure, the best approach is an on-site quote. If you’re considering repainting the exterior at the same time as the roof, combining both jobs usually provides better value. Check out our roof painting service to see what’s involved.
FAQs
Can you paint over existing cladding paint?
Yes, if the existing paint is in good condition. Clean the surface thoroughly, lightly sand any glossy areas to improve adhesion, spot-prime any bare or repaired areas, and repaint. If the existing paint is peeling or failing over a large area, it needs to be removed before repainting.
How often should cladding be repainted in Melbourne?
Every five to ten years for most materials in Melbourne’s climate. North and west-facing walls that get the most sun and UV exposure typically need attention at the lower end of that range.
Can you paint Colorbond cladding?
Yes, but it requires a specialist primer designed for pre-painted steel. Without it, standard acrylic paint will not bond properly and will peel relatively quickly. With the right primer, the result can look great and extend the life of the panels significantly.
Is it better to replace cladding or repaint it?
Repainting is almost always more cost-effective and faster, provided the cladding itself is structurally sound. Replacement makes sense when cladding is physically damaged, has significant rot, or has moisture ingress behind it that can’t be resolved through surface repairs alone.
Does exterior cladding paint protect against the weather?
Yes, that’s one of its primary functions. A quality exterior acrylic creates a barrier against moisture, UV radiation, and heat cycling. This protects the cladding material underneath and extends its service life significantly.
Can fibre cement cladding be painted any colour?
Yes. Fibre cement is compatible with any colour available in exterior acrylic paint ranges. The critical requirements are using an alkali-resistant primer first and applying at least two full coats of topcoat for complete coverage and protection.
