How to Maintain the Lifetime Warranty of Pressure Treated Lumber

What should never be done with pressure treated wood?

Do termites eat pressure treated wood?

Can pressure treated wood be left 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.

Is it better to stain or seal pressure treated wood?
