I just finished installing a 6' Shadowbox fence in my back yard, and have a question about waterproofing or sealing to protect color and protecting the wood.

I used pressure treated lumber, 4x4 post, 2x4 stringers and 5/8x6x6 slats. I've heard that you need to let it cure or dry before you put anything on it!!!!! Will something like Thompson's Water Sealer work, or will I need some other product. I would like for it to maintain the light color if possible. I have spent to much time and money on this project to have it damaged by weather.

Any suggestions would be great.

Thanks

In my opinion, the only thing Thompson's water seal has going for it is a smooth marketing campaign. I use CWF made by Flood. The big box stores carry it. It will last longer, but you'll still need to apply it every few years.

I have some PT 4X4's that originally formed a crib around the base of a tree. They were there for about 10 years.
The tree died, and the cribbing was recovered.
I made garden edging from them and they were in place, semi buried in the ground for another 10 years.
Then I removed them and left them laying out back for another 5 years.
This year I used them as a foundation for a garden shed. Just as sound as the day they were made.
PT lumber has a long guarantee period, and if its left alone, it will last for ages!
