Part # : BI146D - "Broken-In" Magnesium Hand Floats

Achieve a smoother, more consistent concrete surface with MARSHALLTOWN "Broken-In" Magnesium Hand Floats. Designed for professional concrete finishers, these lightweight hand floats feature pre-shaped, worn-in edges that eliminate the time and effort required to break in a new float. The conditioned blade profile helps reduce gouging and surface imperfections when floating wet concrete, so you can prepare slabs for troweling with greater confidence and less rework.

Magnesium combines lightweight handling with the durability and performance needed for demanding jobsites. These hand floats are particularly well suited to air-entrained concrete, helping you achieve consistent surface preparation before moving on to subsequent finishing steps.

Choose from four blade lengths and two handle options to match your project requirements and personal preferences. With a 3-1/8-inch-wide blade, these floats deliver dependable control for efficient concrete finishing.
