Level wide concrete pours quickly without the hassle of a tool break-in period or surface lap lines. The Marshalltown B48B Broken-In Magnesium Bull Float comes factory pre-shaped to deliver smooth, professional results on day one.
Standard raw magnesium bull floats feature sharp square ends that easily dig into wet mud or leave visible tracking ridges across large pours until the tool is broken in. The B48B solves this with a factory pre-ground blade layout featuring upturned, radiused ends that glide effortlessly across fresh concrete in both pushing and pulling directions. Extruded from high-tensile magnesium alloy, this 48-inch by 8-inch float offers superior blade stiffness and warp resistance while maintaining a lightweight operational footprint. It opens concrete pores to bleed off excess water, seals surface air pockets, and leaves a uniform, cream-rich finish ready for final hand or power troweling.
Factory Broken-In Blade Geometry: Pre-shaped and bevel-ground with upturned ends to eliminate sharp corners, preventing the float from digging in or leaving tracking lines.
High-Tensile Extruded Magnesium: Delivers maximum structural rigidity to prevent blade bowing across 48 inches while keeping total tool weight low for extended reach passes.
Surface Pore Preparation: Efficiently levels high spots, fills low voids, and opens surface pores to release trapped bleed water before final finishing.
Complete Bracket Assembly: Includes a universal bracket mounting that pairs seamlessly with standard multi-section threaded handle extensions or pitch-control adapters.
Large Concrete Slab Leveling: The essential primary float for commercial floors, long driveways, slab foundations, and wide patio pours.
Gouge-Free Initial Passes: Perfect for immediately leveling concrete after screeding without tracking lines or edge gouging.
Air-Entrained & Standard Concrete Mixes: Preps surface cream uniformly across all major exterior and interior concrete formulations.
