Watched a crew pour a patio in my neighborhood and saw the same old mistake with the bull float
They were working on a small backyard slab, maybe 15 by 20 feet, and the guy on the bull float was just dragging it back and forth in straight lines. I've seen it a hundred times. That just pushes the cream to the edges and leaves the middle weak. You gotta use an arc, like you're drawing a big 'C' with each pass, to keep that surface cream even. I learned that the hard way on a garage floor job about three years back, had to grind down a bunch of high spots because the finish was so uneven. It seems small, but it makes a huge difference in how flat and strong the top layer sets up. Anyone else notice crews still doing this, or have a different trick for working the bull float right?
