1K waterborne primer produces a rich, amber wood colour. Bona Amber gives wood a similar look to what solvent-based lacquers do, but without the associated risks. It is highly suitable for floors with underfloor heating and/or moving floors, such as end grain or plank floors. The primer is recommended for use on oak and darker types of wood, including tropical species.
