Subtle Flooring Solutions for Jarrah Extensions with Different Climate Growth

When it comes to Jarrah timber flooring, every project tells a different story. In this property, our client had recently added an extension, sourcing Jarrah timber grown in a different climate zone. While still genuine Jarrah, the new timber was much lighter than the existing flooring. This created a clear visual mismatch, especially as we had already restored and finished the front section of the property a few months earlier.

Our task was to carefully sand, bleach and colour blend the new timber so the extension could flow naturally with the older section. Given Jarrah’s strong natural tones, achieving balance required a delicate process of bleaching, sample testing, and subtle finishing.

Before Sanding – Strong Red and Brown Jarrah Tones

The new Jarrah extension arrived with deep red and orange undertones that clashed with the front section of the house. While the client wanted the areas to blend, they also understood that Jarrah timber colour matching has its limits—especially when timber comes from different growing regions with natural variation in tone and grain.

Sanding the Jarrah Timber

We began with a careful timber sanding process to remove the factory finish and prepare both the old and new Jarrah for bleaching. Sanding revealed the raw contrast between the lighter extension and the darker existing Jarrah, making it clear that a direct match was impossible without over-saturating the floor with pigment.

Sampling and Blending the Extension

To find the right balance, we created colour blending samples using bleach, lime wash, and Rubio Monocoat penetrating oil. The challenge was applying just enough lime to reduce the strong red tones without blocking the natural beauty of Jarrah’s grain. Too much lime would have flattened the timber’s character, while too little would leave the extension noticeably out of place.

The final blend was subtle, designed to reduce the contrast between old and new timber while maintaining the natural appearance of the Jarrah floorboards.

Key Takeaways

Jarrah timber sanding and bleaching can reduce strong red and brown tones.
Colour blending with Rubio Monocoat and lime wash creates subtle cohesion.
Natural variation in Jarrah from different climate zones means a perfect match is not always possible, but careful blending delivers a balanced, modern look.

The Finished Look – Subtle but Unified

Once completed, the bleached and lime-washed Jarrah looked far more cohesive across the property. While the extension cannot be matched 100% due to natural differences in grain and tone, the strong red hues were softened, and the result blends far better from a distance.

The client was pleased with how the new section now complements the front area we had previously completed. This project demonstrates how Jarrah colour blending can create unity between old and new sections of a home, even when the timber originates from different climates.
