I was overworking the surface on garage floors for years
A client in Phoenix pointed out the hairline cracks in his 6-month-old slab, and I finally connected it to my heavy trowel passes. Anyone else have a hard time knowing when to stop on a power trowel?

Man, it's so easy to do. You get in that zone trying to get it glass-smooth and you just keep going. I did the same thing on a driveway last fall, and the homeowner called me back in the spring pointing out a spiderweb of cracks. It was a real wake-up call. Now I watch for that sheen and make myself walk away after the last pass, even if my brain is screaming for one more. You almost have to fight the instinct, right?

Yeah I read that too much troweling can bring up too much water and cause shrinkage cracks. It's a tough habit to break lol.
