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-joints showed that much more information can be obtained by this testing method than from laboratory testing methods which are usually applied to determine the biological resistance. Suggestions are made with regard to the assessment and handling of the lap-joints.
