Do you have to treat pressure treated wood?

I live in Utah, a very dry climate. I am going to put in a deck out back using pressure treated lumber. Do i still need to put some kind of sealer on the wood and when do i do that? Before i put it in, right after, or wait a few months for it to weather some? Thanks!Do you have to treat pressure treated wood?
I agree with Allen and Ken. Treated lumber is treated to hold up against the elements. However, even in a dry climate, UV rays will severely impact the wood's performance. I would recommend a deck sealer with UV protection....and make sure you saturate the end-grain, as that is the area that tends to absorb a lot of stain and moisture.
Hi J B, I鈥檓 Ken with The Home Depot. Kenneth is right that pressure treated wood has the chemicals forced deeper into the wood. The only time you would need to treat pressure treated wood is if you cut the wood. You will want to treat the area that was cut.

Pressure treated wood is made for outdoor use. It is a great product. I would only treat the cut end of pressure treated wood, before you install it. I have provided a link to a product that is made for pressure treated wood. Hope this helps.

Pressure treated wood doesn't NEED a sealer but should be sealed if you want to preserve it's color and or appearance. Depending on the type of sealer you use, it can take anywhere from right away to as much as one year to seal your deck. Read the manufacturer's recommendations prior to sealing. There are several sites you could google for specific information.
Pressure treating helps to keep the wood from rotting. But to give it as much life as possible, one should treat it with either a Stain or Thomson's water sealer. This should be done after the deck is completed, then about every 2-3 years in the spring.

Good Luck and enjoy your deck.Do you have to treat pressure treated wood?
You can buy pressure treated wood cheaper than you can treat it yourself....And it will last much longer....you can only treat the surface...pressure treating forces the chemicals deeper into the wood.
