Front door painting is one of the highest-impact, lowest-cost upgrades a Melbourne homeowner can make. A freshly painted door takes less than a day to complete, yet it shapes every visitor's first impression and adds genuine kerb appeal. The catch is that most front doors are painted badly: wrong product, wrong prep, wrong weather. The finish chips within months and the job has to be done again.
Apex Painting handles front door repaints regularly, and the problems we fix are almost always the same few. This guide covers the full process so you get a result that lasts.
Why front doors are harder than they look
A front door is exposed to full sun, rain, wind-driven dust and constant handling. The surface contracts and expands with Melbourne's temperature swings far more than an interior wall does. Standard interior paint can't flex with that movement. It cracks. It peels at the edges. Within a season, the door looks worse than it did before you touched it.
Timber doors are particularly demanding. They absorb moisture and swell in wet weather, then dry out and shrink in summer heat. If your door sits in a north-facing or west-facing aspect, UV exposure is relentless. The right product choice isn't optional. It's the difference between a 12-month result and a 5-year one.
Steel and fibreglass doors have their own demands. Steel rusts if bare metal is exposed for long, so priming isn't just a step you can skip to save time. Fibreglass needs a specific adhesion primer or paint simply won't bond. Knowing your door material before you buy anything is the actual starting point.
Choosing the right paint for the job
For a timber front door, use a high-quality exterior enamel or an exterior alkyd-based trim paint. These products cure to a hard, flexible film that handles the expansion and contraction timber demands. Water-based exterior enamels from Dulux or Solver have improved significantly in recent years and clean up easily. Oil-based enamels still outperform on hardness and levelling, but they take longer to cure and require solvent cleanup.
For a steel door, start with a rust-inhibiting primer, then finish with exterior enamel. For fibreglass, use a bonding primer specifically rated for smooth, non-porous surfaces. Don't skip this step. Paint applied directly to fibreglass without a bonding primer will peel cleanly away within months.
Sheen level matters too. Semi-gloss or gloss finishes are standard for doors because they're scrubbable and they highlight the door as a feature element. Satin works if you want a softer look, but flat or low-sheen finishes are inappropriate for exterior doors. They hold dirt and moisture, and won't stand up to regular cleaning. If you're choosing a bold accent colour, think about how it will read against your home's existing palette. Our guide on how to pick the perfect accent wall colour covers how to approach a standout colour without it feeling disconnected from the rest of the home.
Preparation: the step that determines the outcome
Preparation takes longer than painting. Accept that upfront and the job goes smoothly.
Start by removing the door hardware: handle, lock plate, knocker and any kick plates. Tape off hinges if they can't be removed. Painting around hardware is slower than removing it and produces a worse result. If the door is on a busy entry and you can't take it off its hinges, wedge it open and plan to work in sections.
Sand the entire surface. For a door in reasonable condition, 120-grit sandpaper is enough to scuff the existing finish and give the new paint something to bite into. For a door with peeling or flaking paint, strip back to bare timber or bare metal first. A heat gun works well on timber doors with multiple failing layers. Clean the sanded surface with a tack cloth or a damp rag. Any dust left on the surface will show through the finish.
Fill any cracks, dents or holes with an exterior-grade flexible filler. Don't use interior gap filler outdoors. It isn't rated for UV exposure or moisture and it'll crack out within a season. Once dry, sand the filled areas flat and feather the edges. Prime bare timber and any filled spots before applying your finish coat.
Application: technique for a clean, professional result
Weather matters. Paint a front door on a dry day with temperatures between 15°C and 28°C. Avoid painting in direct summer sun: the surface heats up faster than the paint can level, which causes brush marks to set before they flow out. Early morning is ideal in Melbourne's summer months. The door is in shade, the temperature is manageable and you've got hours before afternoon heat arrives.
Apply paint in this order on a panel door: panels first, then the middle rail, then the stiles (the vertical sides), then the top and bottom rails. This approach keeps a wet edge moving through the work and avoids lap marks where paint overlaps a section that's already started to set.
Use a good-quality synthetic brush, around 63mm wide, for flat sections. A 25mm or 38mm sash brush handles edges and mouldings cleanly. Don't overload the brush. Thin coats level better and dry without runs. Two thin coats always outperform one thick coat on a door because a thick coat sags on vertical surfaces and takes far longer to cure hard.
Allow each coat to dry fully before applying the next. Check the manufacturer's recoat time on the tin. In Melbourne's variable weather, err toward the longer end. Rehanging hardware before the paint has cured fully is the most common reason for marks and scratches that appear within the first week.
After the paint dries
Reinstall hardware carefully. Screwdrivers can slip and gouge fresh paint, so go slowly. Buff any fingerprints off the door face with a clean cloth once the hardware is back in place.
A well-applied exterior enamel on a timber door should hold its finish for 4 to 6 years under normal Melbourne conditions before needing a full repaint. Light cleaning with a damp cloth once a month removes grime before it works into the finish. Catching minor chips early and touching them up with a small brush is far easier than waiting until the paint failure is widespread. If you want to understand what early failure looks like on exterior surfaces more broadly, our guide to spotting the early signs of exterior paint failure is a useful reference.
A front door done right adds more to a home's presentation than almost any comparably priced upgrade. Get the prep correct, choose the right product for the door material, and apply it in the right conditions. The result speaks for itself the moment someone walks up the path.
