Saw my first real burn finish on a warehouse slab in Reno and it humbled me
I did a 40x60 warehouse slab in Reno last month and had to hit it with a burn finish because the owner wanted that hard troweled look, and I totally messed up the first third of it. I was running my old 24 inch trowel too early and left swirl marks all over, plus the edges dried way faster than the middle because of the wind coming off the loading dock. My foreman Ray walked over and told me to just wait, let the bleed water come back, and stop trying to rush the first passes. I slowed way down, dropped my blade pitch, and let the machine do the work instead of muscling it. The difference in how that slab looked after the second cut compared to the first was insane, glassy in one spot and cloudy in the other. Took me about two hours longer than I planned but the customer walked it and said it looked like a showroom floor. Any of you run into that problem where you're fighting the concrete instead of reading it? What's your go to move when the surface starts drying uneven?
