Can pressure treated plywood get wet?
Pressure treatment with chemical compounds does not waterproof the plywood. Continuous exposure to water will leach the preservative chemicals from the wood. Often made with soft wood to enable the penetration of the chemicals. Softer woods will also allow for the penetration of water.
What happens if pressure treated wood gets wet?
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.

Can you build with wet wood?
If you stand your boards up vertically and let them drain or “gravity dry” the rest of the free water drains away leaving the board at 25% or lower. Some species you will see the moisture content falls below 20%. It is at this point that you can start working with the materials.

How long does it take for pressure treated wood to shrink?
