Just finished building a swingset out of PTL and plan on finishing
it. This is the 'new' PTL from Home Depot that isn't green it is
treated with CA- Copper Azole. Has a slight green tint to it which is
probably why it is not rated for ground contact.
I don't know yet if I'm going to finish it with a deck stain/sealer or

You should wait to paint/stain until the wood dries out. For some boards
that could be several months, some could be less. I would opt for waiting a
To say the least. Our daughter's family had the misfortune to hire a
dope to build their home a few years ago. Among the list of things on
