Warning: Tried a magnesium float on a garage floor in Denver last week
I always swore by steel trowels for finish work, but a 30-year veteran at a job site talked me into trying his magnesium float. The slab sealed up way smoother with fewer air holes. Anybody else make the switch and regret it later?

Float them lightly and you won't get those pinholes, but don't overwork it.

Made the switch last year after fighting with pinholes on a garage slab. No regrets here, just gotta keep a light touch like you said (don't get too aggressive with it).
