General comment Blackbutt is one of the most common species of hardwood commercially available from the coastal forests of New South Wales.

Care is needed in drying to inhibit its tendency to surface check on the tangential surface. Reconditioning is seldom advisable because of its effect in widening any surface checks.

It is only fair for steam bending.

It is a poor base for paint because of its tendency to surface check but stain finishes can be used satisfactorily.

The high extractives content of mature wood can cause some gluing problems, especially with phenolic adhesives, but young regrowth wood appears to be much less affected.
