I know that ACQ is suppossed to be more corrosive and that they reccomend satinless fasteners but are there any known problems mixing CCA treated wood with ACQ treated Wood?

I bought a load of CCA lumber early this year (the price was right) and I’m just getting around to using it now.

Now the only thing available around here is ACQ. Obviously, if I run short I’ll need to backfill with ACQ lumber.

Just want to be sure I’m not introduig a problem.

I hope this hasn’t been covered here before – I did a search on CCA and ACQ and found nothing.

Thanks

Chuck
