Heard a guy at the supply yard talking about his crew's new finish routine
I was picking up some fiber mesh in Spokane last Thursday and this older finisher was telling his buddy about how his crew switched to using a magnesium float for the first pass on everything, even flatwork. He said they used to just go straight from the bull float to the steel trowel, but now they do a full pass with the mag float first. He claimed it cuts down on bleed water issues and gives them a tighter surface to start with, especially on hot days. I've always been a steel-first guy myself, so it got me thinking. I tried it yesterday on a small garage slab when the sun was really beating down, and I have to admit, it did seem to pull the cream up a bit nicer without sealing it too fast. I'm not fully sold yet, but it's got me questioning my old habits. Has anyone else made a switch like that in their finishing steps and stuck with it?
