Someone asked the question if I was going to treat the wood that I used on the posts.
That was something that I forgot, and i was planning to write about when I made the posts and enches.
When I was at the big orange home supply center I saw some new treated wood. It’s by Thompson’s, its called Thompsonized wood
he wood was not the normal green treated wood. It’s more of a natural color wood treatment.
This post is treated wood.

The price is about the same as the green treated wood. In fact when i went into the store to buy it I found that the green pressure treated wood was in the same compartment as the thompsonized wood.
According to the advertisement. Their Southern Pine treated wood is available at Home Depot east of the Rockies, the redwood treated wood is available west of the rockies, and the Jackpine treated wood is available in Canada.
I also found on the web this site. Sounds great. They say its the future of treated wood. Timbersil

That is nicer looking then that green crap. I thought they could’nt sell that treated wood anymore due to toxicity. You have a nice looking deck going there Old Pal. Don’t wear yourself out. mike

that is a lot nicer than the other green wood. how is it for toxicity also? thats the main reason why i stay away from the pressure treated (aside from the look). Thanks for sharing!

The deck is the newer pressure treated wood, but it is still green. The Thompson’s product only has a light tint and i only noticed it on some boards that are sitting in the driveway, that I’ll be using for the bench. It is still treated from termites and rotting etc.

Thanks for the update, Karson. I was not aware of the “Thompsonized” wood was the same as treated lumber. In looking at the web site apparently Thompsons assert that the wood is protected to the core which is superior to traditional pressure treated wood that is protected only as far as the treatment can penetrate. I have just completed a tear down of my 21 year old deck that was built with traditional pressure treated pine. The exposed areas, where cuts had been made or boards toe nailed, had a lot of dry rot due to moisture exposure of the untreated wood despite routine applications of deck treatments over the year.
Your post helps me understand why the deck was failing.
Thanks Karson.

Intersting about the treated wood. I’ve heard about the Thompson’s stuff a long time ago but have
never used it.

I looked at their web site and they didn’t say if they were rated for below surface applications. That is a major reason a lot of dyi decks fails the people at the big box store didn’t sell them the right type of PT lumber, some pressure treated isn’t rated for below ground and it will fail. The Thompson’s looks interesting I will have to look into a little more, Thanks

Great blog, Karson. I’m planning a deck off my bedroom that is a ground level one as well. After following your blog I think I’m ready to take a crack at it. I’ll let you know when I do and I’ll post it at HomeRefurbers. Till then, nice work guy.
always,
J.C.
