How long does pressure treated wood last in ground?
Also asked, how long does pressure treated wood last?
Considering this, can pressure treated wood touch the ground?
To start, pressure-treated wood is softwood lumber, typically southern yellow pine, that's been chemically treated to resist rot, decay and termites. Lumber that's stamped "Above Ground Use" should be used only where it won't touch the ground, such as deck railings or fence boards.
Extending the life of your treated wood
- Applying a sealant to the wood is the best choice no matter how the wood is used.
- Filling all nail and screw holes is another way to extend the life of the wood.
- Applying concentrated treatment chemical to any cut ends will increase the life of the wood.
