A common but popular choice of flooring, the blackbutt tree grows in abundance along the east coast of Australia. Known for its resistance to fire, blackbutt timber is a dense hardwood that looks beautiful inside or outside the home. It makes a sturdy deck and is a great natural flooring option for inside too.

Blackbutt provides a different look to most timber decking options being lighter in colour though it does tend to darken with exposure to uv and also following an application of decking oil. Blackbutt is a great choice as it often has a straight grain making it unique to other Australian timber.

care & maintenance

Maintenance is crucial for all types of timber decking in order to keep it in pristine condition.

Different timber species require different amounts of maintenance. Blackbutt, although a durable hardwood, is greatly affected by the elements. Normal recommendations suggest cleaning, scrubbing and sealing your deck every 6 - 12 months. Blackbutt may require more maintenance than other species.

Inside the home, blackbutt will need to be sweeped and mopped regularly to protect the surface from scratching. Blackbutt will also need to be sanded and re-sealed every few years depending on the amount of traffic over the area.
