Effect of natural weathering on the physical properties of Nauclea diderrichii wood was investigated during this study. Twenty four wood samples were obtained from four mature trees of Nauclea diderrichii. Physical properties investigated embody specific density, texture and weight. Main changes in wood samples of N. diderrichii once six months of exposure to weathering factors embody discoloration, surface checking, raised grain and therefore the ultimate loss of fibres. 4.89% and 3.86% of wood materials from wood and duramen severally were lost once exposure as some wood materials were worn away throughout exposure. The study additionally showed that average worths of wetness content were reduced from the initial value of sixteen.81% before exposure to twelve.40% once six month of exposure. Wood degradation and loss of aesthetic worth ensuing from discoloration and loss of fibres from wood samples were attributed to prolonged exposure to weathering factors like downfall, humidity, temperature wind and daylight. The adverse effects of weathering on the wood so indicated that wood materials mustn't be left for too long within the open before use, which wood exposed to downfall, humidity, et.c before application of preservatives or coatings stand the danger of degradation before protection. The study so suggested that wood protection against natural weathering be commenced right away once the lumber is delivered to the log yard as this step would possibly scale back waste within the regions of wood degraded.
