A couple of questions of about deck building and pressure treated wood. I'm getting ready to have a deck built using Trex for the flooring and railing. It's a pretty big size deck, about 1700 sf, so I'm trying to find ways to extend it's life:
1. Any thoughts on whether or not painting the pressure treated wood used for the deck supporting structure will siginificantly increase its life?
2. Does anyone know of any reason not to paint pressure treated wood? Specifically, that wood treated for deck building. I've had a contractor tell me it wasn't adviseable because the chemicals the wood is treated with need to breath.
Thanks,
Stu
