The one time I didn't bleed my air line before a big slab pour
Had this 30-yard driveway pour in Phoenix last July and my finish looked terrible, all pockmarked. Turned out my compressor had been building up moisture for weeks and I never cracked the drain valve before hooking up my tools. Anyone else learn that kind of basic upkeep lesson the hard way?

Wait, you're saying the moisture from the drain valve actually caused the pockmarks? I always figured that was from bad trowel timing or the mix being too hot, never even thought about the compressor doing that.

Yeah @evan_dixon67, moisture from the compressor blows right into your mix and causes little craters on the surface, so I started draining mine every morning before a big pour and it fixed it right up.
