Install Trex over pressure treated 2x6's?
Thanks for the quick response, guys. Whether it is an approved method is pretty much my question because I wonder if the prolonged contact, probably with trapped moisture, between the Trex and PT would cause early decomposition of the Trex. Maybe I'll call Trex and see what they say.
I built a Trex deck off my lower level back in 2006 and I love it. Just give it a quick pressure wash with my electric pressure washer every year or so and its good to go. I am currently staining my main level PT deck and *swear* this is the absolute last time I do this job... applying cleaner, pressure washing, allowing to dry, sweeping, then finally staining. What a way to ruin a couple of otherwise fine weekends. :-/
