If you care about smooth concrete, crisp stucco, or clean mortar joints, the float you choose can make or break the final look. Think of a float as the brushstroke of a mason: the right tool levels, compacts, and finishes the surface, while the wrong one can leave ripples and air pockets. Using the correct float helps you save time, reduce rework, and get a consistent finish that lasts through weather and wear.
A float does more than push material around — it compresses and evens the top layer so it cures uniformly. For example, a magnesium float brings paste to the surface and tightens the texture on a concrete slab, while a wood float provides a slightly rougher surface that helps coatings bond. The choice influences traction, water resistance, and aesthetics, especially when you’ll be staining or sealing later.
Floats come in magnesium, wood, foam, aluminum, and stainless steel. Magnesium gives a smooth, durable finish on concrete; wood is forgiving with mortar and plaster; foam or rubber is gentle for delicate tiles and grout; stainless and aluminum resist rust and are easy to clean. Think about the environment (outdoor vs. indoor), the material you’re working with, and how often you’ll use the tool when picking the construction.
Different jobs call for different floats. You’ll commonly see magnesium floats for finishing concrete, wood floats for initial levelling and plaster, rubber or foam floats for grout and tile work, and stainless or aluminum finishing floats for a super-smooth surface. Learning which float suits which stage of work is like knowing when to use a flat vs. angled paintbrush — each has its moment.
Magnesium floats are a favorite for concrete finishing because they’re lightweight, durable, and leave a smooth, dense surface. They’re often used after screeding and before troweling to bring fine cement paste to the surface. If you’re finishing a 4-foot by 8-foot porch slab, a 16-inch magnesium float is a smart go-to for balancing coverage and control.
Wood floats give a slightly textured finish that’s great for undercoats or when you want a strong bond for subsequent layers. Plastic and foam floats are gentler and often used for tile grout or delicate finishes. If you’re working with stucco or mortar on brick faces, a wood float can help embed aggregates and create a consistent texture that grabs paint or sealers better.
If you’re shopping for masonry floats, the good news is that many familiar US stores stock a range from budget to pro-grade. Below are trustworthy retailers where you can compare brands, prices, and user reviews before buying. Each offers in-store pickup or shipping options, and most have helpful return or price-match policies to give you confidence in your purchase.
Home Depot carries magnesium, wood, and foam floats from brands that suit DIYers and contractors alike. You’ll find 12-inch to 18-inch sizes in-store and online, plus combo sets that include finishing tools like trowels and edgers. Frequent promotions and bulk discounts make it a great first stop if you need tools quickly for a weekend job.
Lowe’s features a solid lineup of floats and finishing tools, often with detailed product descriptions and customer reviews that make selection easier. Their inventory tends to cover all basic materials and sizes, from compact 10-inch floats for tight spaces to larger 18-inch models for patios and driveways. If you like demo videos and step-by-step guides, Lowe’s site can be surprisingly useful.
Ace Hardware stores often carry a curated selection of quality floats and may stock specialty or regional brands not found at the big box chains. The staff at local Ace locations can be helpful for hands-on recommendations, and you can usually find comfortable handles and balanced tools that are ideal for prolonged use on smaller masonry jobs.
If you need a float for occasional use and don’t want to spend much, Harbor Freight offers economical magnesium and wood floats. They’re perfect for homeowners tackling a one-off patio repair or small plaster job. Just remember that lower price can mean lighter duty, so weigh cost versus frequency of use before committing.
Midwestern shoppers will find Menards stocks masonry floats alongside complementary tools like screeds and edgers. Regional independent hardware stores are also worth checking; they can stock professional-grade floats from specialty manufacturers, and you can often pick up advice that’s specific to local materials and climate.
Beyond big-box retailers, online marketplaces and specialty suppliers open up a wider range of brands and professional-grade tools. Amazon has an extensive selection and fast shipping, while specialty suppliers like Grainger or construction-focused stores may carry heavy-duty or contractor-grade floats that last longer on job sites. If you need unusual sizes or ergonomic handles for long shifts, specialty sellers can be a goldmine.
Buying online is convenient and gives you access to reviews and user photos, but testing a handle and weight in person is invaluable for comfort and control. If you’re ordering online, check return terms and read several reviews to get a real-world sense of durability and balance. For frequent use on commercial projects, try a tool in-store before committing to a bulk purchase online.
A few simple criteria will steer you toward the right float: size, material, handle comfort, and edge design. Size affects coverage and control — a 12-inch float is nimble for corners and steps, while a 16- or 18-inch float is better for open slabs. Material determines finish and durability. Handle style influences fatigue, especially if you’re working for hours. Finally, curved or square edges matter for specialized finishing tasks.
For general purpose concrete finishing, most pros carry 12-, 16-, and 18-inch floats. A wider float covers more ground but can feel heavy and less precise in tight spaces; a smaller float gives control around edges and tooling details. If you're planning a 10-foot by 12-foot patio, pairing a 16-inch float for the field with a 12-inch float for the perimeter is a balanced approach.
An ergonomic handle can make a long day of finishing feel manageable. Look for padded grips or handles with neutral wrist alignment to reduce strain. Some commercial floats offer adjustable or anti-vibration handles tailored for repeat use, which is worth the investment if your projects routinely exceed a few hours per day.
How much you spend depends on how often you’ll use the float and how much wear it will endure. Budget options are fine for occasional repairs and small DIY jobs, but they may warp, corrode, or wear faster. Professional-grade floats cost more up front but last longer, resist rust, and maintain straight edges — which saves money over time if you do frequent masonry work.
If you’re finishing a one-off 5-foot walkway or doing a small patch, a budget float from a general retailer will usually do the job. For contractors or homeowners doing entire patios, driveways, or repeated stucco jobs, investing in a quality magnesium or stainless float pays off in smoother finishes and less replacement cost. Consider the tool’s lifespan in months or years, not just the sticker price.
Cleaning and proper storage can double the effective life of a float. After each use, scrape off excess material and rinse with water; for steel or aluminum handles and plates, dry thoroughly to prevent rust. Store floats flat and out of direct sunlight to protect any plastic or wood handles. Simple maintenance keeps the edge straight and ensures consistent finishes on every job.
A quick routine after work: remove loose mortar with a putty knife, spray and scrub with a stiff brush, rinse, dry with a towel, and hang or lay flat. For wooden handles, a light coat of linseed oil every season prevents drying and splitting. For competitive pros, a yearly inspection for warped plates or loose handles keeps safety and performance on point.
Technique matters more than brute force. Start with even pressure, use overlapping strokes, and keep the float moving to avoid gouging. For concrete, begin with a magnesium float to compact paste, then follow with a steel trowel for the final sheen. In stucco and mortar work, float after initial set to embed aggregates and level the surface — but don’t overwork it or you’ll drag paste and weaken the finish.
Think of finishing like ironing a shirt: you smooth in overlapping passes, watch for imperfections, and adjust pressure for different spots. Apply light to moderate pressure on the first pass and increase slightly for final smoothing. If you see blisters or pinholes, reduce pressure and re-float in a crossing pattern to close voids without overcompacting the top layer.
Pair your float with a few key tools for better results: trowels for finishing, edgers and groovers for joints, screeds for initial leveling, and brushes for textured finishes. A good set keeps your workflow efficient and your finished surfaces consistent. Investing in a quality trowel and screed can have as big an impact on the outcome as choosing the right float.
For a versatile kit, get a 16-inch magnesium float, a 12-inch wood float, a half-dozen finishing trowels in varying widths, an edger, and a 4- to 6-foot screed bar. This covers patios, small slabs, grout work, and most stucco patches. Keep everything cleaned and stored together in a toolbox so you’re ready when the weather’s right for a project.
When choosing where to buy, ask yourself: Do I need the tool today? Do I want to try it in hand? Am I comparing warranty and materials? If speed matters, hit a local big-box or Ace Hardware; if you want specialty sizes or pro-grade tools, check specialty suppliers or online marketplaces. Don’t forget to read user reviews and look for rust-resistant materials if you live in humid or coastal areas.
Compare sizes and reads, confirm handle comfort, and note return or warranty policies. If you’re unsure about a size, choose a retailer with flexible returns or pick up in-store to test the balance. Little steps like these help you avoid the common buy-regret of getting a tool that feels too heavy or too unwieldy on the first job.
Picking the right masonry float is an investment in the quality and longevity of your work. From magnesium for smooth concrete to wood for textured stucco, each float has a purpose and a moment to shine. US retailers — from big-box chains like Home Depot and Lowe’s to neighborhood Aces and specialty suppliers — make it easy to find what you need. Spend a little time matching material, size, and handle to your project, care for the tool properly, and your finishes will reward you with fewer call-backs and cleaner results.
