Just a quick update.
It was SLOOOOOOOOOW going. My brother and I put in about 10 hrs on Saturday and my stepdad joined us on Sunday for another 6 hours, and this is all we got done.
Spent the first couple of hours on Saturday truing things up. With the TimberTech XLM material being so 'flimsy', I wanted to remove any crowns in the joists, because I knew the decking would just hump and sag to follow every imperfection. To do that, I built my 'Equalizer', a cheapo Skil planer plus a little outrigger frame made from 2" aluminum angle.
It worked much better than i had imagined. The outriggers average the planer height between the two adjacent joists to take big height variations, and the 'seat' angles keep it centered on the joists.
The whole thing is pretty light, you just lean on the back and keep making passes until you stop making curls. The 2" angle is plenty stiff to keep it from flexing, and the whole thing probably weighs a pound or two. The bolt heads would get hung up on high blocking, but the planer is just friction fit, so you just pop it out, touch up the spot, and put it back in. Worked like a champ!
After that was all taken care of, we started on the decking. I don't do this professionally, so I probably took too much time to make sure everything was good to go before we got started. With just two guys, it's not an efficient process at all, and we only got about 150 sq ft down on Saturday. Three guys is a minimum for an efficient crew, four would be better.
Fortunately, our site supervisor did a good job at keeping morale high
I feel like a bit of a sucker for paying so much for this stuff, but aside from the softness of the fastener screws, the quality of the product is pretty evident. 'Skipper', our sacrificial beater plank used to pound the new boards into the last row of fasteners, took vicious blows from a mallet all weekend long and is quite literally unscathed. It's easy to cut, no crowns, bows, cracks, splits, knots, uneven milling or any other issues to deal with. Installation, albeit tedious, has been easy and i'm hoping that the low maintenance claims pan out...because deck staining sucks.
