Oriented strand board (OSB) was made and tested according to three lay-up schemes, by poplar, bamboo, and the blend of bamboo and poplar. The three lay-up schemes were combined with also three pre-treatments of the material, being treated with acid, alkali or untreated. The surface wettability and the density of free radicals were analysed after treatment with acid and alkali. The physical and mechanical performance of the OSB was tested. The results showed that acid and alkali could improve the surface wettability of bamboo and wood materials. The physical and mechanical performance of OSB could be enhanced. The reasons for this improved performance are theoretically discussed.
