16" Floater For Concrete Stamp

A bull float is used to smooth 95% of a slab, but it has a tendency either to pull a small amount of concrete away from the edges of the slab or to push concrete toward the edge. A hand float is used to level and smooth these areas so that they match the rest of the slab. Floats also can be used around obstacles, such as pipes and drains, where more precision is needed.

Learning how to use a hand float correctly will take some practice, but the techniques can be used on any concrete job. Walkways, patios, and interior work all benefit. First, however, is knowing what type of hand float to use.

These tools are made in several shapes and sizes, and from one of four materials. According to Marshalltown Company product manager Jim Bowie, it’s a common misconception that price is the deciding factor; instead, consider the effect of each of these materials will have on the concrete.

A steel trowel should never be placed on the concrete until all bleed water has evaporated. This tool compresses the top layer of the slab, which adds strength to the surface and gives the slab a durable finish. If used too soon, though, a steel trowel closes the pores of the concrete and traps water below the surface, which would more than likely cause the top layer to delaminate
