Plywood pieces can warp if they have been improperly stored or exposed to moisture. The bowing that occurs is actually the plywood shrinking. You can flatten them again with hot water and a warm environment. This process will take several hours but once it is finished the plywood will be rejuvenated and ready to use for your project. 【Get Price】
