MARSHALLTOWN Cast Magnesium Hand Float 16 in x 3-1/8 in - Smooth

In this review the MARSHALLTOWN Cast Magnesium Hand Float is evaluated for tradespeople and serious DIYers who need a reliable finishing tool for air entrained concrete. The bottom line: this 16 in by 3-1/8 in magnesium float delivers a noticeably smoother finish than typical wood floats and is light enough to use for extended periods, making it a solid choice for finishing tasks like shower pans, patios, and small slab touch-ups. Its cast construction and optional handle choices give a comfortable working profile without sacrificing balance.

Key Features

• Cast magnesium blade: provides a smooth glide over air entrained concrete to reduce surface irregularities and speed finishing work.
• 16 in by 3-1/8 in size: balances coverage and control so the tool is useful for both confined areas and larger hand-finish passes.
• Extra knuckle clearance: the cast shape keeps hands clear of the blade, improving comfort during repetitive passes.
• Multiple handle options: choose DuraSoft, DuraCork, structural foam, or hardwood to match grip preference and job demands.
• Proudly made in the USA: assembled with global materials, offering consistent build quality and serviceability.

Who It's For

The MARSHALLTOWN Cast Magnesium Hand Float is best for masons, concrete finishers, and experienced DIYers who need a lightweight hand tool that produces a smooth, professional surface. It is particularly helpful when working with air entrained mixes or projects where minimizing trowel marks matters, such as shower pans or visible slabs.

Those who should look elsewhere include users who prefer the feel of a wooden float for specific traditional finishes or projects requiring a much larger screed-style float; this hand float is optimized for hand finishing rather than large-scale floating or power troweling.

Pros & Cons

Pros

• Lightweight magnesium construction reduces fatigue during long finishing sessions.
