Marshalltown 16" DuraSoft Magnesium Float

Worth it for contractors who pour concrete regularly. The 1.67 lb weight saves your shoulders on large pours, the comfortable DuraSoft handle actually works, and the magnesium blade provides a mark-free finish. Skip it if you’re stuck on wood floats. Round ends are preferred for eliminating marks.

At 16” x 3 1/8” and 1.67 lbs, this float covers serious ground without wearing you down. Magnesium construction gives you extra knuckle clearance between handle and blade — a detail that matters six hours into a pour. The lightweight and durable design pushes down aggregate to create a uniform surface. Montana’s short construction season means marathon concrete days. Tools that reduce fatigue earn their keep.

Design Options for Different Concrete Work

Three blade configurations address specific finishing challenges. Model 143D features the Round End. Here’s what each design delivers:

Blade Type	Application	Why It Matters
Round End	Eliminate float marks for smoother finish	Preferred for eliminating marks
Beveled End	General leveling	Better balance and weight distribution
Cast Model	Air-entrained concrete	Broken-in shape designed to glide easily over air-entrained concrete

The Cast model’s broken-in shape is designed to glide easily over air-entrained concrete. That matters in Montana where freeze-thaw protection demands air-entrained mixes on every exterior slab. Traditional floats drag and tear the surface. This one glides.

Handle System That Works

The DuraSoft handle uses soft-grip polymer construction. Ergonomic soft-grip reduces hand fatigue. Handle secured with torque pad screws that will not back out — they actually stay tight through temperature swings and jobsite abuse. DuraSoft handles offer superior comfort and fatigue reduction compared to traditional wood, structural foam, or DuraCork handles.

Professional reviews back this up: 4.6/5 stars on Amazon, 4.7/5 on Lowe’s (38 reviews). Pros specifically mention comfortable and ergonomic handle, lightweight and well-balanced design, and high-quality, mark-free finish. No significant complaints show up in retailer summaries.

The Bottom Line

Magnesium floats provide a smoother finish than wood and are more durable and lightweight. Primary applications include smoothing and leveling concrete surfaces before finishing or troweling, pushing down aggregate to create a uniform surface, working with air-entrained concrete, and general concrete slab finishing for floors, walls, sidewalks, and driveways.

Made in USA with global materials. California Prop 65 warning present. Sold individually or in bulk inner/outer packs of 6. Works with standard concrete finishing workflows. Often used alongside Marshalltown trowels, edgers, and groovers.

No assembly required — ready to use out of the box. For Montana contractors dealing with air-entrained concrete on every exterior pour, the Cast model’s design earns consideration. The weight savings adds up over a full day of finishing.

FAQ

What makes the DuraSoft handle different from standard handles?

The DuraSoft handle uses soft-grip polymer construction that reduces hand fatigue. It offers superior comfort compared to traditional wood, structural foam, or DuraCork handles. The handle attaches with torque pad screws that won’t back out during use.

Which blade shape works best for general concrete work?

Round ends eliminate float marks for a smoother finish and are preferred for final passes. Beveled ends offer better balance and weight distribution for general leveling work. The Cast model with its broken-in shape works best for air-entrained concrete.

How much does this float weigh compared to wood alternatives?

The float weighs approximately 1.67 lbs. Magnesium floats are more lightweight than wood floats while providing superior durability. The weight reduction becomes noticeable during extended finishing sessions.

What size projects is the 16-inch float best for?

With 16” x 3 1/8” blade dimensions, this float handles general concrete slab finishing including floors, walls, sidewalks, and driveways. The 16-inch coverage works well for medium to large pours where efficiency matters.
