We present you with a unique parquet-board treatment technology developed by Bonum Wood: CoTanin. This technology involves treatment with special reagents, which, when applied to parquet boards, react with natural tannins present in the wood. This reaction produces an authentic colour that may vary depending on the amount of tannins.

On treatment with the reagents, up to nine different operations are needed to achieve the result. This technology has opened up a completely new colour palette for parquet, diminishing wear and tear, and improving product performance and durability.


Tests prove that products treated with the unique CoTanin technology are 52.21% more resistant to general wear and tear and colour change when compared with natural products and products coated with natural oil, whereas resistance to humidity improves by up to 7.4%.
