Improved resistance of Scots pine and Spruce by application of an oil-heat treatment
2000 - IRG/WP 00-40162
Spruce (Picea abies L. Karst.) and Scots pine (Pinus sylvestris L.) were subject to a heat treatment which was carried out in an oil-bath. The aim was to improve the dimensional stability of the treated wood and its resistance against fungi. The bath of vegetable oil provides a uniform heat transfer at temperatures of 180°C, 200°C and 220°C and protects the submersed wood from oxygen. Heat trea...

Biological resistance of wood treated with waterbased resins and drying oils in a mini-block test
1998 - IRG/WP 98-40107
In recent years it was found that the resistance of wood against fungal degradation could be increased by impregnation with an etherificated melamine formaldehyde resin. Using this resin as a reference, a waterbased fatty acid modificated alkyd-resin and two drying-oils were assessed for their biological performance in a mini-block laboratory test. Although drying-oils, like linseed-oil, are often...

Influence of different resin treatments on the dimension stability of wood
1997 - IRG/WP 97-40090
The dimension stability of wood is considered to be an important contribution to its durability and its performance in practice. A number of different treatments have been developed to improve the dimension stability of wood. One applied method is the treatment of wood with monomers or resins. The application of appropriate impregnation conditions seemed to be essential to enhance the efficiency o...

Interim balance after 20 months of lap-joint exposure
1999 - IRG/WP 99-20164
The application of natural resins and integrated resin systems to improve the performance of Pinus sylvestris was assessed in a lap-joint test according to DIN V ENV 12037 (1996). Lap-joints of Pinus sapwood were exposed at the test field in Hamburg (Germany) in May 1997. The treated lap-joints were assessed with regard to the performance of the resin treatments out of ground. The exposure of lap-...

Detection of Aureobasidium as the dominant fungus on coated wood
2013 - IRG/WP 13-10796
Wood is often covered with a coating in order to protect the surface. Unwanted dark mold growth on paint covered surfaces in external conditions is a familiar phenomenon. Simple microbial techniques have commonly been used to determine the dominant fungal species present in the discoloured area, for example morphological analysis of microscopic preparations of fungal pieces sticking to an adhesive...

Formation of biofinishes on outdoor exposed wood; the impact of wood-oil combination and geographical location
2016 - IRG/WP 16-10864
Growth of dark moulds enables the use of a decorative and protective biofinish for wood, showing advantages compared to traditional wood-coatings in terms of sustainability and self-repair. Based on the formation of a uniform mould covering on oil treated wood during outdoor exposure, the utilisation of a biofinish is in development. Basic information is lacking on the correlation between exposure...

Thermal stability of a wood protective biofinish and the influence of flame retardants on Aureobasidium cells
2017 - IRG/WP 17-30716
In general there is an increasing need for sustainable resources, including sustainable building materials. Wood is one of these sustainable resources and is more used as an outdoor building material. Since unprotected wood will usually be degraded during outdoor exposure, many different protection systems are available on the market. Protection systems containing biocides however might create obs...

Effects of wood protecting biofinish and linseed oil on fire behaviour and leachability of the fire retardant
2018 - IRG/WP 18-30728
A wood protecting biofinish is based on a protective and decorative fungal-based coating and a linseed oil impregnation (called Xyhlo biofinish). This biofinish enables the long-term use of wood in outdoor applications without using toxic chemicals.
The fire resistant properties of materials used in buildings are very important. Since Xyhlo biofinish is relatively new, only little information is ...

Biofinish: A Functional Wood Surface Treatment based on Aureobasidium
2020 - IRG/WP 20-40903
Xyhlo Biofinish is a natural and environmentally friendly wood protection concept based on linseed oil impregnation and a fungal-based coating. It emerged in the late 1990s and has been developed over the past 15 years into an industrially applicable process in the Netherlands. The combination of linseed oil impregnation and a surface treatment with the living fungus Aureobasidium extends the serv...
