I know the new ACQ lumber is extremely corrosive. I read that the old CCA treated lumber isn't nearly as corrosive. I used regular nails when toe nailing some studs into the 25 year old CCA treated lumber bottom plate. I already put up the siding. I was wondering if I should go back and remove the regular nails and use hot dipped galvanized. How corrosive is CCA lumber in a dry location? I heard framers used to use regular nails in the old days by mistake (forget to change the nails).
No announcement yet.
