Swore by power trowels for years, now I'm back to hand finishing on garage slabs
Watched a neighbor's garage floor get ruined by a power trowel burn last month - that shiny spot never went away. Tried hand finishing my last 2-car slab with a fresno and a kneeboard, and the control was way better. Anybody else had an issue with power trowels leaving marks on smaller pours?

Huh, I see it a little different. I have had power trowels work great on smaller pours like garages if you keep em flat and don't overwork it. The trick is matching the blade pitch to the concrete set and never letting it get too dry before you start. You ever try a lighter machine with combination blades instead of the heavy pan? That burned look usually comes from using too much weight or starting too late.
