RFI: Composite Lumber Decking Boards

[rob_s]

I did my deck like that because I knew a guy who put a nails width between the boards and when it dried the gaps were so large a thin heel on a womans shoe would go between the cracks. At this point probably 30 years later in the same house if I were going to re do it for my house id take the deck down and pour a patio. Ive seen tools like a cantilever that help push the boards up tight. The best thing to protect a deck is a roof over.

the tool is designed such that they are taking drying into account. IIRC the gap on the tool for PT boards is 1/16" with the expectation that the gap will ~double when using "wet" wood. The tool they make for composites, which won't shrink and therefore won't grow the gap, is ~1/8".

ETA:
now that I type all of that out, I probably should have used the composite tool on my pre-dried boards...

That looks like a pretty slick system.
