Well, so far, use it before it sits on a trailer for 6 to 8 months. Luckily it’s a weathered look anyway, so the blending of the sun bleached boards looks natural.
They say UV Resistant/no fading, but it fades.
By not waiting, you also are more likely to remember the pattern you were doing and won’t have to reframe twice.
I’d research fasteners more. The ones that were suggested are actually too short for the decking I bought, they don’t work as advertised.
According to the instructions you screw them down tight for the previous board, then you slip the next boards edge under the opposite side and repeat.
I’m making these work by leaving the fasteners up 1/8” and tightening the previous set after the next board has its fasteners down and left up an 1/8”.
Composite, at least this stuff, requires 12” on center framing, there may be some that does not, so research that. My framers left mine at 24” OC, as they thought it was treated 5/4, which still should have been no more than 16”OC.
I realized they weren’t deck guys, so just asked them to stop and would do the decking myself.
