12 February 2025Ever walked into your bathroom or loungeroom and found bits of paint flaking off the wall? Maybe it's happening around your old windows or above the shower, classic Sydney stuff, right?
As local painters, we see this everywhere from Bondi's salty air to the humid backrooms of Parramatta. It’s annoying, but the good news is, you can often fix it without too much fuss, if you know what you’re doing. Here’s how we tackle peeling paint in Sydney homes, plus when to call in the professionals.
Paint flaking or peeling is a common issue that affects both interior and exterior surfaces. It can make walls, ceilings, doors, and wooden surfaces look unattractive and, if left untreated, may lead to further deterioration.
Understanding why paint peels and how to fix, repair, and prevent it can save you time, effort, and money. This guide will walk you through everything you need to know about dealing with peeling paint on wood, walls, and other surfaces.
Why Does Paint Peel or Flake?
Paint peeling occurs due to various reasons, including:
1. Moisture and Humidity
High humidity levels cause paint to lose adhesion and blister, leading to peeling.
Water leaks from roofs, windows, or pipes can seep into walls, weakening the bond between paint and the surface.
Bathrooms, kitchens, and basements are more prone to peeling due to moisture exposure.
2. Poor Surface Preparation
Applying paint on dirty, dusty, or greasy surfaces prevents proper adhesion.
Failing to remove old, peeling paint before repainting can lead to additional layers detaching over time.
3. Using the Wrong Paint or Primer
Incompatible paint types (e.g., applying oil-based paint over latex or water-based paint) can result in peeling.
Skipping primer, especially on porous surfaces like wood or drywall, leads to poor adhesion.
4. Temperature Fluctuations
Extreme heat causes paint to expand and contract, eventually leading to cracks and peeling.
Painting in cold weather prevents proper drying and adhesion.
5. Poor Quality Paint
Low-quality paint lacks strong binders, making it more susceptible to peeling and flaking over time.
Exterior and Interior Peeling Paint

Peeling Paint on Interior Surfaces
Walls and Ceilings: Peeling in high-moisture areas like bathrooms and kitchens is common.
Doors and Trim: Constant handling and cleaning can weaken paint adhesion.

Peeling Paint on Exterior Surfaces
Wooden Surfaces: Outdoor wood exposed to sunlight, rain, and snow can cause paint to peel.
Metal Surfaces: Rust and corrosion can cause paint layers to bubble and flake off.

18 month build, white walls possibly only whitewash used.
When wiping over the walls the paint comes off which has left extensive patches throughout the property.
Paint can not be matched.
The real estate is demanding I paint the whole property but my argument is that the walls weren’t prepared correctly or undercoated. Any advice on what I can put in an email to them that is fact? NSW
Absolutely. If the surface isn’t prepared properly, the final coat will likely peel. By the way, are any other neighbors experiencing the same issue? If they are, you could list them as witnesses to support your case.
