A finisher in Boise watched me mag a slab and said 'you're floating the cream to death,' and he was right
I was working a 1,200 sq ft driveway pour in Boise last month and this older finisher from another crew stopped by while I was on the power trowel. He didn't say much at first, just watched. Then he goes, 'you're floating the cream to death, kid.' I had been running the trowel at a higher rpm than I needed and leaning into it hard, thinking I was getting a better finish. He told me I was working the paste up and burning the surface. I dropped my rpm down, lessened my angle, and let the machine do the work instead of forcing it. The finish came out way more even and I didn't get that blotchy look I'd been fighting on my last few jobs. I've been finishing for 9 years and nobody ever broke it down like that for me. That one sentence from a stranger fixed something I didn't even know I was doing wrong. How do you guys judge your rpm and angle on a trowel? Do you go by sound, by feel, or by watching the cream?

Is a slightly blotchy slab really worth changing your whole technique over?
