Before & After — See the Difference
Real results from a recent job. Soft wash removes years of biological growth completely — killing it at the root so it doesn't grow back within months the way pressure washing results do.
What is Light Oxidation?
Oxidation is a natural chemical process that affects metal and painted surfaces when they're exposed to UV radiation, heat, oxygen and moisture over time — all of which Queensland has in abundance.
On colorbond roofs, gutters and fascia, oxidation causes the protective paint binder to break down. The pigment separates and rises to the surface, leaving behind that distinctive chalky, faded, powdery appearance. Run your hand across an oxidised colorbond surface and you'll see the colour come off on your fingers — that's the oxidised paint layer.
On rendered walls, oxidation combined with weathering causes the surface coating to lose its sheen and take on a dull, streaky or discoloured appearance that regular washing alone won't fix.
Light oxidation — which is what we treat — is the early to mid stage of this process. The surface looks faded and chalky but the underlying paint and substrate are still sound. At this stage, professional oxidation removal can restore the surface without any repainting.
Heavy or severe oxidation — where the paint has broken down deeply or the substrate is exposed — is beyond the scope of our treatment and typically requires repainting or resurfacing. We'll assess this honestly when we quote.
Signs You Have Light Oxidation
Chalky or powdery residue — colour transfers onto your hand when you wipe the surface
Faded colour — your colorbond was once a deep, rich colour and now looks washed out or pale
Dull, flat appearance — the original sheen or satin finish has disappeared
Streaking after rain — oxidised pigment washes down onto walls and gutters leaving chalky streaks
Uneven colouring — some areas more faded than others, usually sun-facing roof faces
Age 10+ years — most colorbond roofing begins showing oxidation between 10–20 years depending on exposure and quality
Light vs Heavy Oxidation
We're upfront about what our treatment can achieve. Here's an honest guide to what gets great results versus what needs repainting.
✓ We Can Treat This
- ✓Chalky, powdery surface that transfers colour to touch
- ✓Visibly faded colorbond with original colour still visible
- ✓Dull gutters and fascia that have lost their original sheen
- ✓Rendered walls with surface discolouration and dullness
- ✓Oxidation-driven chalk streaks on walls below gutters
- ✓Light to moderate oxidation on north and west-facing surfaces
- ✓Colorbond aged 10–20 years in reasonable condition
✗ Beyond Our Treatment
- ✗Severe oxidation where bare metal or substrate is exposed
- ✗Peeling, flaking or blistering paint that has fully delaminated
- ✗Physical rust, corrosion or structural damage
- ✗Surfaces where the original colour is completely unrecoverable
- ✗Colorbond with heavy pitting or surface breakdown
- ✗Any surface requiring repainting or resurfacing
Surfaces We Treat
Colorbond Roofs
The most common surface we treat in Queensland. North and west-facing roof faces oxidise fastest due to UV exposure. Our treatment removes the chalky layer and restores depth of colour significantly.
Gutters & Fascia
Gutters and fascia boards are often the first place oxidation becomes noticeable — they're exposed on all sides and age quickly. Treatment restores their original appearance and reduces chalk streaking down your walls.
Rendered Walls
Rendered and acrylic-coated walls lose their sheen over time and develop a dull, streaky appearance. Our treatment addresses surface oxidation and weathering to restore a cleaner, more consistent finish.
Fascia & Trim
Colorbond fascia, bargeboards and trim pieces that have become dull and faded. These smaller elements make a big visual difference when restored — tightening up the whole look of your roofline.
