Timber Hardness: Does It Matter, and What Should You Know Before Choosing?

When choosing a timber floor, one of the most common questions is: “How hard is it?” And while hardness does play a role in durability, it’s not the only factor that determines how a floor performs or how it looks over time.

In fact, some of the most beautiful floors are made from timbers that dent a little more easily. Why? Because those dents tell a story. They add character. And with today’s advanced coatings and repair options, timber flooring is more resilient than ever.

Understanding Timber Hardness

Timber hardness is measured using the Janka rating, which tests how resistant a wood species is to denting and wear. Here’s a quick comparison of popular flooring timbers:

Timber Species: European Oak
Origin: Europe
Janka Rating (kN): ~6.0
Notes: Stable, easy to work with, widely used in engineered flooring

Timber Species: Tasmanian Oak
Origin: Australia
Janka Rating (kN): ~5.5
Notes: Light, versatile, and popular for its neutral tone

Timber Species: Blackbutt
Origin: Australia
Janka Rating (kN): ~9.1
Notes: Hard, durable, and great for high-traffic areas

Timber Species: Spotted Gum
Origin: Australia
Janka Rating (kN): ~11.0
Notes: Very hard, with rich colour variation

Timber Species: Sydney Blue Gum
Origin: Australia
Janka Rating (kN): ~9.0
Notes: Dense and striking, with a reddish hue

Timber Species: Ironbark
Origin: Australia
Janka Rating (kN): ~14.0
Notes: Extremely hard — one of the toughest timbers available

Timber Species: Blackwood
Origin: Australia
Janka Rating (kN): ~5.0
Notes: Softer, but prized for its warm tones and grain character

Timber Species: American Hickory
Origin: USA
Janka Rating (kN): ~8.6–9.5
Notes: Tough and resilient, with bold grain and rustic appeal

Does Hardness Equal Quality? Not Always.

Harder timbers resist denting, but they can also chip more easily if impacted. Softer timbers may dent — but those dents often blend into the floor’s natural patina, adding warmth and personality.

The real game-changer today is manufacturing quality. At Sunstar, our engineered timber floors are coated in our factory with 7 to 12 layers of UV-cured finish, depending on the colour. That’s far more than the typical 2–3 coats applied to traditional solid timber floors on-site — even high-end installations rarely exceed 5 coats.

More coats mean better protection, longer life, and easier maintenance.

How to Fix Scratches and Minor Damage

Even the best floors get scratched, but that doesn’t mean they’re ruined.

• Minor surface scratches: Wipe a small amount of spray kitchen oil across the scratch, then buff off with a paper towel. This helps blend the mark into the finish.Important: If the scratch goes through the coating, don’t leave oil on the floor — it can soak into the timber and cause a dark stain.
• Deeper scratches: Use a wax stick (available at most hardware stores – see Bunnings Timbermate) to fill and blend the mark. Choose a colour that matches your floor, and follow the instructions for best results or watch a YouTube tutorial and take your time to master it.

Hardness matters but it’s not everything. The beauty of timber flooring lies in its natural variation, its ability to age gracefully, and the quality of its construction. Whether you choose a dense Australian hardwood or a softer European oak, what really counts is how well it’s made, finished, and cared for.

At Sunstar Timber Flooring, we combine premium materials with advanced coatings to deliver floors that are built to last and easy to love.
