View Full Version : sistering joists - pressure treated lumber?

I need to sister some joists for a bathroom floor.

I think I read some time ago that you shouldn't use pressure-treated lumber, because it changes dimensions?

Is that true or is that a figment of my imagination, or, more to the point, what SHOULD I use to sister the joists?

Thanks all!

Yes it shrinks,


Use your garden variety #2 framing lumber,*kd* if you can,,, glue it, nail it.
Your done and your floor will be happy.
