Why Choose Spotted Gum Decking?

When it comes to choosing decking materials for your outdoor spaces, durability is a key factor that can greatly influence your decision. With a wide range of timber decking options available, Spotted Gum stands out as a highly popular choice.

In this blog, we discuss the durability of Spotted Gum decking and the factors that contribute to its popularity.

What is Spotted Gum?

Spotted Gum is an Australian hardwood species known for its striking appearance and excellent natural strength. This species is primarily found along the eastern coastline, from Queensland to New South Wales. The timber features a distinctive blend of golden browns, rich reds, and occasional black streaks, making it a visually appealing option for decking.

Factors Contributing to Durability

Timber Properties Overview

Bushfire Rating BAL29

Durability Class 1 (Above Ground)

More than 40 years above ground and 15-25 years in-ground

Naturally resistant to termites

Low tannin content

Hardness: 10.1 Janka Rating

Pre-drilling is recommended due to density.

Density and Strength

Spotted Gum is classified as a high-density hardwood, which lends itself to greater durability against wear and tear. Its density allows it to withstand heavy foot traffic and the impact of outdoor furniture. The density of Spotted Gum not only enhances its strength but also its ability to resist warping and splitting. Although its high density means that pre-drilling is required, Spotted Gum decking machines well and readily holds fasteners.

Natural Resistance

One of the standout features of Spotted Gum is its natural resistance to decay and insect attacks. This timber contains natural oils and tannins that protect it against pests and moisture-related damage. In addition, Spotted Gum decking has a bushfire rating of BAL29, making it ideal for bushfire prone areas.

Application of Coatings

Another benefit of Spotted Gum decking is its ability to readily accepts oils, stains and polishes. While Spotted Gum is naturally durable, applying appropriate coatings can further enhance its lifespan. High-quality sealants and stains can protect the timber from UV rays, preventing fading and ensuring the vibrant colours remain intact. With the ability to readily accepts these coating, regular maintenance becomes a lot easier and quicker to achieve.

Comparison to Other Common Decking Materials

When compared to other common decking materials such as pine or composite decking, Spotted Gum offers superior durability. Softwoods like pine can warp, splinter, and fade more quickly, while composite materials, although low maintenance, often lack the aesthetic appeal and natural warmth of timber.

Visual Appeal

Although not entirely contributing to durability, Spotted Gum decking is sort after for its visual appeal. The timber’s unique grain patterns and rich colours create a striking outdoor space that complements a range of architectural styles. Spotted Gum decking has a low tannin content, making it ideal for areas near paving or brickwork. Unlike hardwoods with a high tannin content, such as Merbau, Spotted Gum is less likely to cause staining.
