Fungal coating

Xyhlo Biofinish

Xyhlo biofinish is a living protection layer that can be applied on wood. This coating is based on the presence of fungal cells and chlamydospores that adhere to the wood through biopolymers, which form a coating that can repair itself. Moreover, the quality improves during the first years of use, in contrast to the conventional coatings that deteriorate from the first moment.

Made from

  • Naturally occurring fungus Aureobasidium pullulans
  • Linseed oil
  • Thickener
  • Pigment
  • Natural emulsifier

Production process

The fungus is placed in a sterile and nutritious rich water solution, where it grows in a natural way. After mixing (formulating) with substances noted above, it can be applied to wood in a mechanical way (rolling, spraying).

A fungus on your house, it’s actually not that weird


The coating is already widely available and can be applied in many ways.

  • Making materials more sustainable
  • UV protection
  • Coloring of material
  • Organic, transparent black stain for consumers
  • Facade cladding for building

Environmental impact

Xyhlo Biofinish consists entirely of natural raw materials and a living fungus. The product and / or parts of the product can be reused in various ways at the end of its life. Biofinish could even provide valuable chemicals after the end of its life (upcycling). The biofinish is expected to last up to 100 years. This makes it a very sustainable coating.

Growth opportunities

Xyhlo currently produces a couple of thousand liters of Biofish per year. What forms a challenge is the unfamiliarity with the product among potential buyers. This is related to the completely new product philosophy and the conservatism in the market. Therefore a lot of communication is required to communicate the principle of the concept.
