Fig. 3From: Effect of oil impregnation on water repellency, dimensional stability and mold susceptibility of thermally modified European aspen and downy birch woodComparison of visual mold growth on the surfaces of the thermally modified (TM) and non-TM wood impregnated with three different oils after the accelerated mold test in a climate chamber at 27 °C and 92% relative humidity (RH) for an incubation period of 21 days. Unimpregnated samples from non-TM material of aspen and birch are regarded as controlBack to article page
