Also to know is, how long do you have to wait to seal pressure treated wood?

It is important to wait for the wood to dry before sealing a new deck, but at the same time, you don't want to wait too long. Drying can take several months. We recommend beginning to test the wood around 90 days after your project is completed, but this is just a general suggestion.

Do I need to seal pressure treated fence?

Treated lumber is often used for decks, fences, and sheds. When the lumber is used, it is typically painted or stained. This is great for the time being, but after time passes the paint or stain will wear off and you will need to seal it again. You can then begin to treat the wood and reapply paint or stain.
