They are typically offered in aluminum, magnesium, or fiberglass in 4- to foot lengths, and often can be interlocked to create longer lengths. Buy fiberglass handles if you plan to work in areas with overhead power lines, because fiberglass won't conduct electricity.
Not all bull floats come with bracket assemblies for attaching handles, so you may need to purchase those separately as well. For better control, buy an adjustable tilt-action bracket that lets you change the float pitch with a simple turn of the handle. On hand floats, look for handles that are screwed to the blade so the handle can be replaced if it splits or breaks.
The handle also should be positioned for good balance, allow adequate knuckle clearance, and have a comfortable grip. Wood hand floats are available in variety of types, including teakwood, bodark wood, and redwood. Each type may produce a different surface texture, so it's always wise to experiment. Rubber floats are good choices for producing textured or slip-resistant finishes because they bring more sand to the surface.
The price of wood floats varies, depending on the type of wood used, but will generally be lower than the cost of magnesium. Floating should be done after the edging and jointing operations.
Floating helps remove imperfections and produces a flatter surface. It also compacts the slab and the mortar at the surface in preparation for later finishing operations. Floating can be performed by machine or by hand. If floating is done by hand, a magnesium float is recommended, particularly on air entrained or lightweight concrete.
Sweep a magnesium float across the concrete in wide arcs, holding it at a slight angle facing away from you. Press down on the back edge as you go.
This will carry on where the darby left off, pushing down coarse aggregate and bringing up finer material to leave a smoother, denser finish. If you want more textured concrete, for instance to create a non-slip surface, you can swap the magnesium float for a wooden one, which will leave a slightly rough finish.
Alternatively, use a stiff bristled broom to make a slightly ridged surface when the concrete has partly hardened. Push or drag the broom across the slab in one direction only, to create uniform lines.
Remember to wash the broom immediately afterwards. With an edging tool, work your way around all sides of the slab pressing down with long, smooth strokes to neatly separate the edges of the concrete from the wooden form. For a smooth finish, go over the slab with a steel trowel once the surface water has drained away and the material has begun to harden. Hold the trowel almost flat and swing it in large circles while pressing down on the concrete.
Repeat no more than two or three times. Keep the concrete moist for the next five to seven days. This slows down the curing setting process and will make the concrete stronger. You can do this by using a water sprinkler, covering the concrete with clear polythene or applying a curing compound. The concrete should then be left to cure for about four weeks.
