Coated L-joints have been used for decades to evaluate the performance of wood preservatives in protected environments. This study was conducted using matched coated and uncoated L-joints to simulate above ground protected and unprotect exposures. When exposed to constant moisture in a greenhouse environment, coated and uncoated L-joints give very similar performance results. In contrast, exposing coated and uncoated L-joint out-of-doors revealed that the coated L-joints performed worse than the uncoated samples.
