commercial painting adelaide painting an older Adelaide home is not always as straightforward as choosing a colour and applying a few coats of paint. Older properties can have multiple layers of previous coatings, ageing plaster, timber details, masonry, repairs and surfaces that require more careful preparation than a modern home.
There can also be heritage and safety considerations. Some older South Australian homes may contain lead-based paint, while properties that are heritage-listed or located within a State Heritage Area can have specific requirements relating to external painting and alterations.
Adelaide’s climate is another factor. The city experiences wet winters and warm to hot, dry summers, so exterior coatings need to cope with seasonal changes in moisture and weather exposure.
Before repainting an older Adelaide home, it is worth understanding the condition of the existing surfaces, the history of the building and any requirements that may apply.
Start by Understanding the Age and Character of the Home
An older house can contain more than one generation of building materials and paint.
You may find:
- Multiple layers of old paint
- Original timber windows and architraves
- Decorative mouldings
- Older plaster
- Masonry or rendered walls
- Previously repaired cracks
- Weathered exterior timber
- Different substrates within the same room
The age of the house can also influence how you approach preparation.
A newer home with a relatively intact previous coating may only require cleaning, minor repairs and preparation. An older property with decades of repainting may need considerably more investigation before the new coating is applied.
Before starting, inspect the walls, ceilings, trims, doors and exterior surfaces individually rather than assuming the entire house requires the same preparation process.
Check Whether the Property Has Heritage Requirements
Being an old house does not automatically mean it is heritage-listed.
However, if a property is a State Heritage Place or is located within a State Heritage Area, painting and other changes may require consideration under South Australia’s planning and heritage framework.
The South Australian Department for Environment and Water states that, within a State Heritage Area, development can include the alteration or painting of a place, although exemptions can apply in specific circumstances. Relevant changes generally need to go through the appropriate planning authority.
That means homeowners should check the property’s heritage status before making significant changes to the exterior.
Why colour can matter
For a heritage property, painting is not necessarily just a modern decorative decision.
Heritage conservation guidance can consider the original appearance, materials and colour scheme of a building. The department recommends understanding a heritage property’s significance and historical context before undertaking conservation work.
If you are unsure about the status or significance of your property, check with the relevant council or Heritage South Australia before commencing external work.
Older Paint May Contain Lead
Lead paint is one of the most important safety considerations when repainting an older Australian home.
SA Health advises that homes built before the mid-1970s, particularly those built before 1940, are more likely to contain lead-based paint. It also points out that older lead paint can remain underneath newer coats, meaning the visible topcoat does not necessarily tell you what is underneath.
This matters most when preparation involves disturbing old coatings.
Scraping, sanding or mechanically removing old paint can generate dust and paint flakes.
What should you do before removing old paint?
If you are unsure whether an older coating contains lead, consider having it tested before undertaking substantial paint removal.
SA Health recommends lead-aware precautions for older homes and provides guidance on lower-dust removal approaches, including wet sanding and wet scraping where appropriate.
Do not treat old paint removal as an ordinary sanding job if lead may be present.
For extensive preparation or uncertain surfaces, using a contractor experienced with lead-aware renovation practices can be a safer approach.
Inspect the Existing Paint Before Recoating
One of the biggest mistakes when painting an old home is assuming that the existing paint is a suitable foundation for the new coating.
Look for:
- Peeling paint
- Flaking
- Blistering
- Cracking
- Chalking
- Bubbling
- Water stains
- Mould
- Powdery surfaces
- Bare substrate
- Previous patch repairs
A new coat of paint cannot stabilise a failing layer underneath it.
If the existing coating is loose, it needs to be removed or stabilised using an appropriate preparation system before repainting.
This is especially important on exterior walls, where moisture and weather exposure can accelerate coating failure.
Repair the Wall Before Painting
Older homes often have imperfections that have accumulated over many years.
Small cracks, dents and holes can generally be repaired before painting, but the repair method should match the substrate.
For example, plaster, plasterboard, masonry and timber can require different fillers, sealants or preparation systems.
Don’t simply fill a crack and immediately paint over it.
A proper repair generally involves:
- Removing loose material.
- Cleaning the area.
- Applying an appropriate repair product.
- Allowing it to dry or cure.
- Sanding or smoothing the repair.
- Priming or sealing where required.
- Applying the finish coats.
Recurring cracks deserve additional attention. If the same crack continues to reopen after repair, determine whether movement, moisture or another underlying issue is responsible.
Be Careful With Original Timber Features
Older Adelaide homes can contain timber elements that contribute significantly to their character.
These may include:
- Window frames
- Doors
- Architraves
- Skirting boards
- Decorative trims
- Verandah details
- Fascias and eaves
Avoid automatically replacing or heavily altering original features simply because they look worn.
First determine whether the timber can be repaired and prepared for repainting.
Where timber has deteriorated, the damaged section may require repair rather than simply filling the surface and covering it with paint.
For heritage properties, retaining significant original fabric can be particularly important. South Australia’s heritage guidance recommends understanding the significance of the building and doing no more work than necessary when undertaking conservation work.
Choose Paint According to the Surface, Not Just the Colour
Older houses can contain several different substrates, so one paint system may not necessarily be suitable for every surface.
For example, the requirements for:
- Interior plaster
- Plasterboard
- Exterior render
- Brick masonry
- Timber
- Metal
- Previously painted surfaces
can differ.
The existing coating also matters.
Before choosing a product, check the manufacturer’s recommendations for the substrate, existing coating and intended location.
For interiors, rooms such as kitchens and bathrooms may need more washable or humidity-suitable coatings than bedrooms.
For exterior surfaces, the coating needs to be appropriate for outdoor exposure and the particular substrate.
Consider Adelaide’s Climate When Painting the Exterior
Adelaide has a Mediterranean climate, with cold to mild wet winters and warm to hot dry summers. Most rainfall occurs between April and October.
This seasonal pattern matters when planning exterior painting.
A wall may look dry on the surface while retaining moisture in the substrate. Painting over an inadequately dry surface can contribute to coating problems.
Summer brings a different consideration. Very hot surfaces can affect how quickly paint dries and how the coating forms.
The specific manufacturer’s application requirements should therefore determine when the product is suitable to apply.
Don’t choose a painting day solely because the forecast says there is no rain.
Salt, Damp and Masonry Need Extra Attention
Some older Adelaide properties, particularly those in coastal environments or with masonry construction, may have issues involving moisture and salts.
If paint is bubbling, flaking or deteriorating around the lower sections of masonry walls, don’t automatically assume the problem is simply old paint.
Look for signs such as:
- White salt deposits
- Damp patches
- Bubbling coatings
- Crumbling masonry
- Persistent staining
- Peeling near the base of walls
South Australia’s heritage resources include specific technical guidance on older buildings, rising damp and salt attack.
If damp or salt movement is suspected, investigate the building condition before carrying out extensive cosmetic painting.
Painting over an active moisture problem may only hide the symptoms temporarily.
Should You Strip All the Old Paint?
Not necessarily.
Complete paint removal can be appropriate when existing coatings are extensively deteriorated or unsuitable for the new system. However, stripping every layer from an older property can also create unnecessary work and may disturb historic fabric or potentially hazardous coatings.
The better approach is to assess the existing coating.
If it is sound and compatible with the proposed system, suitable preparation may allow it to remain.
If it is unstable, contaminated or badly deteriorated, more extensive removal may be necessary.
For older homes where lead paint is possible, the method of removal becomes particularly important. SA Health recommends lead-aware, lower-dust practices where old lead-based paint may be disturbed.
Choosing Colours for an Older Adelaide Home
Colour selection deserves more thought on an older property than simply following current trends.
Look at the building’s:
- Architectural period
- Roof colour
- Brick or stonework
- Timber details
- Window frames
- Verandah
- Existing decorative elements
For a heritage property, historical research may help determine an appropriate colour approach.
South Australian heritage guidance notes that original paint schemes can sometimes be investigated through paint scrapes and historical evidence when considering conservation work.
For a non-heritage older home, you have more flexibility. You can modernise the colour scheme while still retaining architectural details that give the house its character.
Interior Painting Requires Its Own Preparation Strategy
Older interiors can present different problems from exteriors.
Before painting rooms, check for:
- Hairline cracks
- Water stains
- Peeling coatings
- Wallpaper residue
- Old gloss finishes
- Patch repairs
- Mould
- Powdery surfaces
Walls should be cleaned and repaired before applying new paint.
If the room has previously been painted with a high-gloss coating, additional preparation may be needed to achieve good adhesion with the new system.
Kitchens and bathrooms deserve additional attention because humidity, condensation and frequent cleaning can place greater demands on the coating.
When Should You Use a Professional Painter?
Professional help is particularly useful when an older Adelaide home has complicated preparation requirements.
Consider getting an experienced painter involved when:
- Multiple paint layers are failing.
- Lead paint may be present.
- Large areas require paint removal.
- Exterior timber is deteriorated.
- The property is heritage-listed.
- Damp or salt attack is suspected.
- Cracks continue to return.
- Different substrates need different coating systems.
- Extensive repairs are required before painting.
For heritage properties, South Australia’s Heritage South Australia maintains a register of heritage trades and consultants, including painters and conservation specialists.
The right contractor should be able to explain the preparation process rather than simply providing a price for applying paint.
Common Mistakes to Avoid
Assuming every old house needs complete paint stripping
Some sound coatings can remain after suitable preparation. Complete removal should be based on the condition and requirements of the coating system.
Sanding old paint without considering lead
Older coatings may contain lead. Assess the risk before disturbing them.
Painting over damp walls
Find and address the moisture source before applying a new decorative coating.
Ignoring heritage status
External painting can be considered development for properties within State Heritage Areas, subject to applicable exemptions. Check before starting.
Covering original details
Don’t automatically remove or replace timber mouldings, trims or other features that may contribute to the home’s character.
Choosing paint only by colour
The substrate, existing coating and room conditions should influence the paint system.
Rushing preparation
On an older house, preparation can be more significant than the actual painting. Cutting preparation time can compromise the finished result.
Frequently Asked Questions
Do old Adelaide homes need special paint?
Not necessarily. The appropriate paint depends on the substrate, existing coating, room conditions and exposure. Older homes often need more careful preparation rather than a completely different type of paint.
How do I know if my old house has lead paint?
Age can indicate a higher risk, but it does not confirm whether a particular surface contains lead. SA Health advises that homes built before the mid-1970s, especially before 1940, are more likely to contain lead-based paint. Testing can provide more information.
Can I repaint a heritage-listed house?
Potentially, but requirements depend on the property’s heritage status and location. External painting can require development approval for State Heritage Places and properties within State Heritage Areas, subject to applicable exemptions. Check with the relevant planning authority before commencing work.
Should I remove all the old paint before repainting?
Not always. If existing paint is firmly adhered and suitable for the proposed coating system, it may be possible to prepare and repaint over it. Extensive removal may be necessary where coatings are failing or unsuitable.
Why does paint keep peeling from my old exterior walls?
Possible causes include moisture, poor preparation, chalking, deteriorated substrate or unsuitable previous coatings. Recurring failure should be investigated rather than repeatedly covered with new paint.
Is winter a good time to paint an old Adelaide house?
Exterior painting needs suitable conditions rather than simply following a particular season. Adelaide’s winters are wetter and summers are generally warmer and drier, so the paint manufacturer’s requirements and actual site conditions should guide scheduling.
Final Thoughts
Painting an old Adelaide home is an opportunity to refresh the property without losing the features that make it distinctive. But the quality of the result depends heavily on what happens before the first coat of finish paint goes on.
Start by checking the property’s age, condition and heritage status. Assess old coatings carefully, consider the possibility of lead paint, investigate moisture and repair damaged surfaces before choosing the final paint system.
For heritage properties, seek the appropriate advice before changing external colours or finishes. For older homes with extensive peeling, multiple coating layers or uncertain surfaces, an experienced painter can help determine what needs to be removed, repaired, primed and repainted.
A careful preparation plan may take more time at the beginning, but it can make the finished result far more appropriate for an older Adelaide home.
