Buying Guide: Choosing the Best Magnesium Float for Your Concrete Projects
Selecting the right magnesium float depends on your project scale, finishing technique, and budget. The best magnesium floats share core characteristics but differ in size, handle design, and blade shape. Understanding these factors helps you invest wisely.
Blade Material: Cast vs Extruded Magnesium
Cast magnesium floats undergo a molding process that creates pre-shaped broken-in edges. This manufacturing method produces blades ready for smooth finishing without wear-in time. Cast magnesium typically costs more but delivers immediate professional results.
Extruded magnesium floats come from a different process that shapes metal through force rather than casting. The performance difference is minimal for most users. Both materials resist warping and corrosion while providing smooth concrete finishes.
Blade Size and Shape Selection
Hand floats range from 12 to 20 inches in length. The 16-inch size hits the sweet spot for most residential and light commercial work. Longer floats cover more surface but require broader strokes. Shorter floats work better for detail areas and confined spaces.
Blade width typically spans 3 to 3.75 inches. Wider blades accelerate coverage but challenge edge and corner work. Narrower blades sacrifice coverage speed for precision control. Your finishing style influences which width suits your approach.
Round-end floats eliminate transition marks between strokes. Beveled-end floats define edges more precisely. Choose round ends when surface appearance matters most. Choose beveled ends when corner definition and edge work require precision.
Handle Types and Comfort
DuraSoft handles provide ergonomic grip comfort with synthetic material that resists moisture and wear. These handles suit most users and deliver consistent performance across varying conditions. MARSHALLTOWN and premium brands favor DuraSoft construction.
Wood handles offer traditional feel at lower prices. The grip comfort varies based on wood quality and handle shaping. Basic wood handles cost less but may cause fatigue during extended use compared to ergonomic designs.
Cork handles represent premium natural grip options. Cork absorbs moisture and provides tactile comfort synthetic materials cannot match. Cork handles require maintenance but deliver comfort serious finishers appreciate.
ProForm plastic handles from Kraft Tool offer ergonomic shaping at mid-range prices. These handles resist wear and provide consistent grip regardless of moisture conditions. Some finishers prefer plastic while others favor natural materials.
Broken-in vs Pre-broken-in Blade Design
New magnesium floats sometimes require wear-in time before edges smooth enough for mark-free finishing. Pre-broken-in designs come shaped for immediate professional results. Cast floats often feature pre-broken-in edges through manufacturing processes.
Budget floats may require several concrete pours before edges soften properly. The wear-in period creates inconsistent results until the blade shapes through use. Pre-broken-in designs eliminate this learning curve and deliver professional quality from first use.
Hand Float vs Bull Float Categories
Hand floats suit projects where you can reach the entire surface from standing positions. These tools work for residential slabs, sidewalks, and small flatwork. Hand floats remain manageable for detailed work and edge finishing.
Bull floats become necessary for large pours where surface size exceeds hand float reach. The extended handle system lets you work from slab edges while floating distant areas. Commercial projects, large warehouse floors, and extensive flatwork require bull float capability.

FAQs
What are magnesium floats good for?
Magnesium floats smooth and level freshly poured concrete surfaces before final finishing. They seal the concrete surface while pushing aggregate down and drawing moisture to the top. This creates a tighter, smoother base for troweling or decorative work like stamping and staining.
When to use a magnesium float?
Use a magnesium float after screeding when bleed water disappears from the concrete surface. Timing matters because floating too early traps moisture while waiting too long makes the surface hard to work. Most concrete needs floating within 20-30 minutes after screeding, depending on conditions.
Is a magnesium float better for concrete?
Magnesium floats seal the concrete surface while wood and resin floats open it. Sealing creates a tighter finish that prepares concrete for troweling. For decorative work requiring stain penetration, wood floats work better. For standard finishing, magnesium floats deliver smoother results with less effort.
