Weatherboard is everywhere in Melbourne, from bayside beach cottages to inner-suburb period homes — and it fails faster than any other exterior surface when it's painted badly. Here's how the job is done properly, and why preparation is roughly 70% of the work.

Water is the second difference. Every board overlap, joint, nail hole and window reveal is a potential entry point, and once water gets behind the paint film it lifts the coating from underneath. That is why weatherboard peels in sheets rather than fading evenly.
For most Melbourne weatherboards a flexible water-based acrylic exterior system — such as Dulux Weathershield or Taubmans All Weather — over the appropriate primer is the right choice. Coastal homes benefit from the more heavily weather-resistant options in those ranges, because salt air and reflected UV are harsher than inland conditions.
On colour, mid-tones and lighter shades hold up better on weatherboard than very dark colours, which absorb more heat, move the timber more and fade faster on north and west-facing walls.
A properly prepared and painted weatherboard exterior in Melbourne typically lasts 7 to 10 years. Bayside and coastal homes exposed to salt and full sun sit at the shorter end of that range, while sheltered walls last longer.
Repaint when you see chalking, flaking, bare timber or gaps opening at the joints — not after the timber has started to rot, which turns a straightforward repaint into a repair job.
Call a professional when the home was built before 1970 and may contain lead paint, when there is visible rot or boards need replacing, when the house is two storeys or needs scaffolding, or when previous paint is peeling in large sheets — which usually signals an underlying moisture problem.
Jetblack Painting has painted weatherboard homes across Melbourne's bayside, southeast, inner east and the Mornington Peninsula for over 13 years. Every exterior job is quoted in writing with the preparation itemised, and backed by $10M public liability insurance and a 5-year written workmanship guarantee.
Most Melbourne weatherboard homes need repainting every 7 to 10 years. Bayside and coastal homes exposed to salt air and full sun often sit at the shorter end of that range, while sheltered south-facing walls can last longer. Flaking, chalking, bare timber and gaps opening at the joints are the signs it is due.
Yes. Any bare or newly exposed timber must be spot-primed before topcoats, using an oil-based or alkyd primer that penetrates the grain. Skipping this is the most common cause of early peeling on weatherboard homes, because water gets behind the paint film through the unsealed timber.
A flexible, water-based acrylic exterior system such as Dulux Weathershield or Taubmans All Weather suits most Melbourne weatherboards. Flexibility matters because timber expands and contracts with temperature and moisture, and a brittle coating cracks at the board edges.
Exterior painting needs dry timber and moderate temperatures, so Melbourne winter work is weather-dependent. Most exterior acrylics need above roughly 10 degrees Celsius and a dry surface to cure properly. Jetblack Painting schedules exterior weatherboard work around the forecast rather than pushing on in unsuitable conditions.
Homes built before 1970 may have lead-based paint. It should not be dry-sanded or power-sanded, as that releases lead dust. Testing first and using safe preparation methods is essential — this is a job for an experienced painter rather than a DIY sander.
