OK, I have this free standing deck that comes off my house. There are a few floor joists that need to be replaced. From what I can see, the original boards are not treated lumber. The boards were primed and painted. Now, I would like to replace these boards with treated lumber. A couple of questions.
1. How much does rested lumber shrink as it dries? What I don't want to happen is have bows in my decking when the lumber dries out. I know this would be years down the road, but I don't want to have to deal with it again.
2. Is there anything that can be put over fresh treated lumber so a paint can be used? Or, do I have to wait a year or so to let it dry out before I can paint it?
Thanks
