Pressure treated wood used inside the house
Since I'm a rookie and I believe everything i read on the internet and what people tell me :), I was told that in my basement I cant put regular wood on the concrete because it will rot.

So in a few places I replaced some 2x4's with PT 2x4's, a buddy of mine told me today that it is dangerous to have PT in my basement as it contains arsenic, he recommended that I should remove them.

I come to you fellow DIY'ers to set the record straight, who is right and is it OK to have PT inside the house? Thanks guys

Your buddy was right 7 or 8 years ago. They changed the treatment for decks, just for that reason.

good, i wont bother putting any more in the house from here on out but what a pain in the *** it would have been to remove and re-install.

When inspecter find lumber touching concrete without poly between in new houses they call for the same treatment painted on. The poly between is a better way to go. In some places they build house with on a pressure treated wood foundation, but in a finished basement, that would be outside the envelope. I assume some of these houses don't have finished basements.

Poly between the wood and the concrete is best. I have even seen it allowed to put new wood over old vinyl tile (which does act as a barrier).

There is also Blu-Wood (Canada) which is very interesting but I have not seen it in the USA.

Havn't seen the blue wood out west yet. Warm wood wood would still cause water to wick which would still evaporate into the living space so I think the poly would still be a good idea.
