Can t111 plywood be used to make the florr of an outdoor deck?

T111 plywood is not typically recommended for outdoor deck floors due to its susceptibility to moisture and potential for warping or rotting over time. While it can be used in certain applications, treated lumber or specifically designed outdoor decking materials are more suitable for durability and longevity. If T111 is considered, it should be properly sealed and maintained to extend its lifespan.
