If you live in an older Perth home, there is a roughly 1-in-3 chance you are walking on Jarrah. This iconic Western Australian hardwood is the backbone of our local architecture, known for its incredible density, rich red-to-brown tones, and legendary durability. However, many of these beautiful floors are currently hidden under old carpet or masked by decades of yellowed, peeling varnish.
At Ryan’s Flooring, jarrah floor sanding in Perth makes up a huge portion of our work. From the wide-board floors of Fremantle to the classic narrow boards in Dianella, we know exactly how to bring this timber back to life. Here is everything you need to know about restoring your Jarrah floors.
Why Jarrah is Unique
Jarrah (Eucalyptus marginata) is one of the densest timbers you’ll find. On the Janka hardness scale, it sits significantly higher than most European or American hardwoods. This makes it incredibly hard-wearing, but it also means it requires a specific approach during the floor sanding process. You can’t rush Jarrah; it requires the right grits and the right machines to get a perfectly smooth, level finish.
Common Jarrah Variations in Perth
Depending on when and where your home was built, your Jarrah might look very different:
- Heritage Wide Boards (120-130mm): Common in Mount Lawley, Fremantle, and North Perth. These floors often have character-rich gaps and older repairs that need careful attention.
- Standard Narrow Boards (60-65mm): The workhorse of mid-century Perth suburbs like Booragoon and Dianella. These floors are often in remarkably good condition once the old coatings are removed.
The Best Finishes for Jarrah
Choosing the right coating is the most critical decision in your jarrah floor sanding Perth project. Jarrah is a “reactive” timber, and its deep reds can look very different depending on what you put on top.
1. Water-Based Polyurethane (The Clear Choice)
If you want to keep your Jarrah looking modern and avoid that “traditional orange” look, a high-quality water-based finish is the best choice. Because it stays clear, it allows the natural variations of the timber—from deep chocolate browns to vibrant pink-reds—to be seen clearly. It’s also extremely tough for family homes.
2. OSMO Hardwax Oil (The Natural Warmth)
OSMO is a game-changer for Jarrah. It penetrates the wood and brings out a “glow” that plastic coatings simply can’t replicate. It enhances the depth of the grain and provides a tactile, natural feel. It’s also much easier to perform spot repairs on if you ever scratch the floor.
3. Solvent-Based Polyurethane (The Traditional Glow)
For some heritage restorations, the classic “amber” glow of a solvent finish is exactly what’s required. It darkens the wood and adds a rich, glossy depth that many Perth homeowners still love. Just be aware that it will continue to darken and “orange” over time due to UV exposure.
Common Issues We Fix in Jarrah Floors
Over our 500+ projects, we’ve seen it all when it comes to Jarrah:
- “Black Japan” Stains: Many older Jarrah floors have a dark border painted around the edges of the room. This needs careful, deep sanding to remove without thinning the boards too much.
- Carpet Contamination: Old glue, staples, and years of dust can take a toll. We specialize in “carpet-to-floor” transformations.
- Yellowing: Old solvent finishes turn Jarrah into a muddy orange. Sanding back to raw wood is like giving the room a face-lift.
Expert Tips for Jarrah Homeowners
If you are planning a jarrah floor sanding Perth project, remember that Jarrah “moves” with the seasons. In a dry Perth summer, you might see small gaps appear between the boards; in a winter, they will close up. This is normal behavior for a solid timber floor. We’ll discuss whether “trowel filling” is the right choice for your specific floor during our site visit.

Jarrah is a gift to Perth homeowners. It’s a world-class timber that, if treated correctly, will last for generations. Whether you want a contemporary matte look or a traditional high-gloss finish, Ryan’s Flooring has the expertise to make your Jarrah floors the standout feature of your home.
