Recommended for smaller slabs and medium-to-low slump concrete, the LBG 800
bull float screed provides deeper vibration and single-step levelling.
Do not use a 4- to 5-foot
bull float. A
bull float can smooth the surface but it cannot perform the cut-and-fill process; and due to its short length, its use will reduce the floor flatness.
Instead, rent a
bull float (shown above; $20 per day).
Almost immediately after the screed passes, workers can begin floating the surface with the
bull float. The
bull float, a wide, flat metal blade with a long handle, is pushed and pulled over the surface several times.
Bull float; To smooth and level horizontal surfaces, eliminating any high or low spots or ridges left by the straightedge.
Three or four passes with the
bull float is usually sufficient.
Smoothing of the surface with a
bull float and hand float follows.
If you can't reach the entire slab from the edges with a darby, rent a
bull float and handle to use instead.
Use the
bull float right after screeding (Photo 12) if there's no bleed water present.
Smooth the surface with a
bull float, round the edges along the forms with an edger, and finish the surface with a finishing broom.
* a
bull float for the first smoothing--be sure to get two or three extension handles;
The
bull floated downstream for about 200 yards before becoming lodged in a pocket of rocks in the shallow water at the river's edge.
