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.
; 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
