Karndean Smart Lay Longboard is a 5mm hybrid plank, and that slim profile is the point: a low-profile board is easier to run into an existing home without rebuilding door clearances or fighting large height differences at thresholds, which makes it a practical choice for renovations rather than new slabs only. The ten colours are unusually weighted towards Australian species instead of the usual European oak look — QLD Spotted Gum, NSW Spotted Gum, Royal Gum, Snowy Gum and Midnight Gum cover the gum tones from pale through to near-black, while Washed Oak, Sunny Oak, Light Distressed Oak, French Grey and Rustic Grey cover the oak and grey end. For matching existing spotted gum or blackbutt elsewhere in the house, this range gives more gum options than most.
