Just had a builder come by and suggested this. Looked at a this old house web site on it. Less $ than Al decking. Will see what they propose. Said they were booked up but our “small” job could be worked in.I had an IPE (Brazilian ironwood) deck installed over PT SYP framing about 7 years ago. No treatment (stain, etc.) except end grain sealer at installation. It has weathered to a pleasing (to me) grey patina; pressure washed last year, patina quickly returned. IPE is relatively expensive and difficult to work, cobalt to pre-drill for SS fasteners, carbide to cut. It has outlasted a friend's "mahogany" deck and is more stable and cooler underfoot than the plastic composite decks of other friends.
what is your grating setting on? is it normal wood frame? I'd love to hear more about this.I don't ever want to paint a deck board ever again. Front deck is FRP grating with tile over that and the back deck is the same grating but concrete pavers on top.
