In response to wood scarcity in Nigeria, this study investigated bamboo as an alternative raw material for interior applications. Bamboo culms from the University of Ibadan were processed into strips and treated with boric acid and sodium hypochlorite solution. Dyeing was done using a pressure method with caustic soda and sodium sulphate. From 35 bamboo culms (average length: 269 cm), the initial recovery rate was 81%, decreasing to 36% after planning. The treatment brightened the bamboo’s colour, which varied from dark carton brown to vibrant shades. Moisture content dropped from below 12% to 9.1%, eventually settling below 13% after dyeing. Density increased from 600 kg/m3 to 664 kg/m3. Dye penetration was 0.6 mm for black, red, and pink, and 0.55 mm for blue and yellow. The study concludes that using the pressure method approach to infuse dye colour into bamboo culm strips may not make the product suitable for external application due to the minimal penetration depth but can be suitably used to produce items meant for interior application.
