Can I leave treated wood in the rain?
While the chemicals in pressure treated lumber prevent rot and ward off insects, they don’t prevent moisture from seeping into the wood. On a deck that’s going to be directly exposed to rain, water can seep into the boards and cause them to swell. As they dry in the sun, they’ll shrink.
