Board size1820–2100 × 136 mm
Thickness18 mm
Surface & finishPrefinished, 12 coats water-based polyurethane
Grey Ironbark Solid 18 mm is the hardest board in our solid range. It is Grey Ironbark all the way through, 18 mm thick with a tongue and groove profile. It comes prefinished from the factory with 12 coats of water-based polyurethane, so the floor is already finished when it arrives. There is no sanding and coating on site after it is laid. Boards are 136 mm wide in random lengths of 1820–2100 mm, graded Standard and better.
Colour: honey tan, not grey
The name comes from the tree's bark, not the floor. On our sample boards the timber is honey tan through to reddish brown, with a few much darker boards mixed in and scattered gum veins and small dark flecks. The overall effect is warm and lively, so it sits in our warm browns. If you want an actual grey floor, look at our neutral grey shades instead.
Hardness
Janka hardness is 14 kN. For comparison, solid Spotted Gum is 11 kN and solid Blackbutt is 9.1 kN. A higher number means the surface resists dents better, which helps in kitchens, hallways and homes with heavy furniture. Slip resistance is a D1 pass under AS 4586 Appendix B.
Grey or Red Ironbark?
Red Ironbark is a close relative at 13 kN. Its boards lean towards a muted pinkish brown with more knots and swirling figure, while Grey Ironbark reads more honey and tan. Both come in the 136 mm width only.
Installing it
Solid boards are usually secret-fixed to joists or battens, or laid over a slab on a suitable base. Solid timber moves more with humidity than engineered board, so it needs time to acclimatise. It is not for bathrooms or laundries. See the full solid timber range.

Questions
Frequently asked questions
Why is it called Grey Ironbark if the boards are brown?
The name refers to the grey, deeply furrowed bark of the tree. The timber itself is tan to reddish brown, with some darker boards mixed through.
How much harder is Grey Ironbark than Spotted Gum?
Grey Ironbark rates 14 kN on the Janka scale, against 11 kN for Spotted Gum and 9.1 kN for Blackbutt. It is the most dent resistant of our solid boards.
Can Grey Ironbark be sanded in future?
Yes. It is solid timber all the way through at 18 mm, so it can be sanded back more times over its life than an engineered board with a 3 mm wear layer. Because it is so hard, sanding takes a little more work.
What warranty comes with Grey Ironbark Solid 18 mm?
For homes, 25 years structural and 5 years on the factory coating. For commercial use, 10 years structural and 3 years on the coating. Structural cover is about the board itself; coating cover is about the finish. The exact term is confirmed on your quote, and our installation work and your Australian Consumer Law rights are separate.
