Knightsbridge Chevron Raw Oak Wood Flooring 14 x 90 x 510 (mm)

The invisible oil is formulated not to add the amber tone a conventional oil gives, so the boards keep the colour of freshly sanded oak and the pattern reads pale and dry.

An invisible oil is maintained like any oil, locally and with the manufacturer's own maintenance oil for the same finish, because a conventional oil would darken the patch. The brushing hides the dark marks a pale floor shows. Chevron needs a careful set-out from the centre line and a higher cutting allowance than planks. Tongue and groove, micro-bevelled, listed as compatible with underfloor heating; a box of 16 boards covers 0.734 square metres, and the manufacturer's warranty is 15 years.

The Knightsbridge Chevron Natural Brushed is the same board in the conventional warm oak tone with a matt lacquer. For a pale herringbone instead of chevron, the Oxford Light Oak and Light Brushed blocks; for a pale plank with the same invisible finish, the Cobham Invisible Oiled Oak.
