Does pressure treated lumber rot non treated lumber when they are in contact with each other?
I’m building a shed with pressure treated flooring. I was told that I could not place kiln dried framing on the pressured treated floor because it would rot the wood.
Both of your previous answers contain some truth. Pressure Treated will not cause any other lumber to rot. If you have rot it is because the elements got to the other lumber. Framing wall studs with pressure treated is not a good idea. PT is a much lower grade of lumber that is only to be used in areas susceptible to moisture contact.
