Why You Need a Concrete Floor Grinder
When it comes to all-in-one construction tools, a concrete floor grinder is a must. Whether the job involves grinding down uneven concrete slabs, leveling joints, removing stubborn tile or vinyl glue, smoothing and polishing surfaces, or even cleaning industrial contaminants, these powerful machines eliminate the need for chemical etching, making quick work out of concrete surfacing jobs both big and small, However, not all concrete grinders are created equally, which means choosing the best one for the job is key to getting it done right.
Which Floor Grinder is Right for You?
Concrete floor grinders come available in two different sizes: handheld and stand-up. Handheld floor grinders are great for tight spaces but can be limiting when used for bigger projects. On the other hand, stand-up grinders are usually about the size of a standard vacuum and offer several advantages over their handheld counterpart, including getting the job done faster and easier.
Weight is an important factor in concrete surface grinding and polishing. While handheld grinders may come with the convenience of portability at a lower price, they come with the additional cost of time and labor – not to mention a much larger margin for error.
Applying even weight distribution when grinding or polishing a concrete surface can be challenging to achieve when using a handheld grinder – especially when its operation requires getting on the hands and knees. On the other hand, stand-up concrete grinders allow users to keep their feet on the ground while the machine’s weight does the work for them, making them ideal for both large jobs or simply getting any job done more efficiently.
When it comes to choosing the best concrete floor grinder for your needs, you’ll also find two different types to choose from: planetary and rotary. The main difference between the two is in the configuration of the machine’s grinding discs and weight.
Planetary vs. Rotary Concrete Grinders
Named for its similarity to how the solar system works, planetary grinders are configured with one large plate that serves as the central point to several smaller discs that rotate at different speeds using belts and pulleys. The smaller discs do all of the grinding and polishing while the large plate stays in its central position, never coming into contact with the floor. Planetary grinders are generally lightweight and easy to maneuver in a straight line, making them an excellent option for less intensive tasks like smoothing a garage floor.
Rotary concrete grinders are much heavier than their planetary counterparts and are best used for larger, more aggressive jobs. Instead of a belt and pulley system, rotary grinders use heavy-duty geared construction. When it comes to plate configuration, rotary grinders use either one or two large rotating discs or several small rotating discs that directly grind or polish the floor. While the heavier weight can help speed up the process, it also makes the machine much harder to maneuver, thus requiring a higher skill level.
While both have their pros and cons depending on the job, one of the most significant advantages planetary grinders have over rotary grinders is the ability to cover larger surface areas with its multiple rotating discs evenly. This gives the machine much better balance compared to its one- or two-headed counterpart, thus offering more even weight distribution and less operator fatigue. When you add its ease of use to its lighter weight, it’s obvious the planetary grinder is the way to go. The next step is finding the best one to get the job done.

Concrete Grinders Are Versatile Machines for Floor Grinding
Concrete grinders use horizontally rotating discs to perform a multitude of tasks, from light texturing to open the pores of the surface to removal of paints and thin coatings. The key to their versatility are the grinding attachments, which are available in a variety of types and grits to suit different applications.
Because grinders use rotary action rather than impact to remove material, the depth of material removal is limited to about 1/8 inch, depending on the type of attachment used. They generally leave behind a smoother profile than scarifying or shotblasting, and when working on hard, dense concrete they may polish rather than abrade the surface.
WALK-BEHIND CONCRETE GRINDERS
For floor and slab surfaces, you can find walk-behind grinders ranging in size from single-disc units for working in small or restricted areas to dual-, triple- or even four-disc machines for high-production grinding of large slabs. A single-disc grinder has a working width of 10 to 12 inches while a dual-disc unit covers 20 or more inches in one pass. Disc rotation speeds range from about 250 to over 3,000 rpm. On multiple-disc units, the discs usually are counter-rotating to provide balanced torque so the grinder won’t pull from side to side.
For more even grinding, some machines are also equipped with floating heads that will follow the contour of the floor and adjustable rear wheels to keep the grinding discs level. Many manufacturers offer a choice of power options, including electric, gasoline and propane. Most machines are equipped with vacuum ports for dust-free dry grinding. Some models also include water mist systems so they can be used with wet- or dry-cutting attachments.
Although walk-behind machines are well suited for profiling large slab surfaces, you can also buy handheld grinders for working in tight areas where larger units can’t maneuver, such as in corners and close to walls. These smaller workhorses are available with grinding diameters ranging from 5 to 12 inches and can also be used to remove bumps, form marks, and graffiti from vertical surfaces or to grind concrete countertops (see A Definitive Polisher for Concrete). Like their larger cousins, handheld units come with a selection of grinding accessories and can be hooked up to an industrial vac for dust control.
WAYS TO USE A CONCRETE FLOOR GRINDER
Many of today’s grinders can serve multiple functions and are generally more adaptable than other types of surface prep equipment, especially when it comes to decorative work.
They are good for the following applications:
- Profiling floors before application of thin coatings or paints because they won’t create ridges in the surface, as can scarifiers
- Breaking up deposits of grease, dirt and industrial contaminants
- Leveling uneven joints or high spots
- Removing paint, sealer or other coatings
- Polishing concrete surfaces (grinders with finer-grit abrasives)

The three most common types of grinding attachments are:
Some grinders are also available with scarifying attachments for removing thicker coatings and mastics.

Available in various grits for coarse or fine polishing, silicon-carbide stones are an economical choice for such applications as smoothing trowel marks or rough finishes and leveling high spots less than 1/16 inch. However, these stones can clog easily, which can make them inefficient at removing most coatings.
Tungsten-carbide inserts and diamond grinding accessories remove surface coatings with greater speed and efficiency. Tungsten-carbide inserts are carbide-tipped blocks with beveled edges that can strip heavier buildups or coatings without digging into the concrete. Their removal action, which is similar to using a scraper, works best in materials thicker than 1/16 inch. Applications include removing adhesives, thick paints, resins, tar, industrial buildups and rubber deposits.
For profiling work and removal of thin-film coatings or coatings with high hardness values, such as urethanes and epoxies, diamond-segmented abrasives are generally the best solution. Other applications include polishing and removing minor surface imperfections. The diamond segments, which are bonded to a backing plate or to removable block inserts or plugs, sit on the surface and are embedded in a metal or resin matrix. During grinding, the matrix wears away gradually to expose new diamonds. You can choose diamond tooling in various grit levels, ranging from fine to coarse, and with different bond hardnesses, shapes and diamond concentrations, allowing you to match the tool to your project requirements.
Regardless of the attachment you use, look for inserts or grinding discs that are easily replaceable. This will allow you to move more easily from coarser to finer grit levels.

Tips for Best Results
- Despite their versatility, grinders generally aren’t designed for aggressive profiling jobs, and there are certain coatings a traditional grinder just can’t remove. They are most effective at removing thin coatings and paints or for cleaning and lightly abrading floor surfaces.
- When deciding between tungsten carbide and diamond attachments for coating removal, the main factors to consider are the material type and thickness and the strength of the mechanical bond to the surface. One manufacturer offers this tip: If the material to be removed can be cut with a knife, use tungsten carbide. Diamond segments are more suitable for thinner coatings no greater than 1/16 inch.
- When using diamond tooling, it’s important to choose the right bond hardness of the matrix (the material that holds the diamond segments) to achieve greater efficiency and to maximize tool life. In general, use a hard bond when grinding soft materials and a soft bond for hard materials. Softer materials wear away the diamonds more quickly.
- The weight of walk-behind grinders can make a difference in grinding performance. Heavier units permit more aggressive grinding because they place more weight on the discs, allowing them to make better contact with the surface. Ballast weights can be added to some machines for tackling more difficult material removal jobs.

Concrete Grinding and How Much Can A Grinder Remove?
Most people are searching for what concrete grinding is? Another important question for all newbies is how much will a concrete grinder remove?
Let’s go deeper into details. Concrete grinding is a mechanical treatment process of the surface using special equipment, like Husqvarna or HTC, combined with abrasive diamond tools. The metal segment attachments procure the removal of unevenness on rough concrete surfaces to reveal a smooth finish. In addition, there are grinding diamond tools to help make the process faster.
Have you ever been struggling to remove old mastic or glues, waterproofing membranes, or epoxy coatings from a concrete surface? It’s a bit of a challenge most concrete resurfacing contractors, fluid floor applicators, and even waterproofers have. The main goal is to simplify the methods of removing materials from concrete surfaces. Thus, preparation to reapply a coating, membrane, or adhesive will be enjoyable.
Why It Is The Best Method Of Concrete Floor Prep?
Firstly, concrete mechanical treatment can be accomplished either dry or wet. Prepping the floors before installing hardwood or tiles is the best way to ensure the floors’ endurance.
It is also important when the concrete will be polished or coated with epoxy, as the quality of the surface will show through.
What are the benefits of Concrete Mechanical Treatment?
- Rebuild concrete surfaces. Removes all inconsistencies and imperfections, resulting in a usable and smooth surface.
- Remove dirt, paint, or mastic. The best way to get rid of different remnants left on the concrete.
- Install flooring (coatings, carpets, or tiles). A contractor can easily install any flooring on a smooth surface. Floor prep is key in the longevity of a new covering option.
How Much Will a Concrete Grinder Remove?
Let’s find out how much will a concrete grinder remove? As a matter of fact, a concrete grinder can remove as much concrete as you wish, but its limitations are:
- the hardness of the concrete;
- the type of diamond tooling;
- the amount of time you spend on the floor.
A small planetary concrete grinder with basic grinding tools will remove around 1/16” of the concrete in 1-2 passes in a normal situation. You might be able to remove more – 1/8’’ if use a heavier concrete grinder and more aggressive PCD tools. In fact, an angle grinder with a cup wheel will do the best job.
It will be easier to grind in the case of soft concrete, especially if you use highly aggressive PCD tools for concrete layer removals like glue, black mastic, or other imperfections.
Lastly, the more pressure you put on the grinder, the more wear you put on the diamond tools. If you need to remove a thicker layer of concrete faster, you may need an extremely soft bond grinding pad.
Finally, concrete grinding is often seen as a finishing or refinishing procedure. But if you have a thick layer to remove, contractors suggest a complete demo and re-pour the slab.
How Long Does Grinding Take?
Do people also ask about how long does grinding takes? As a matter of fact, the time of concrete grinding depends on a few factors:
- How big is the project?
- Whether the area is quite open, or it consists of a lot of small spots?
- What kind of finish do you expect – polishing or sealing?
- How much exposure of aggregate do you want to see?
- What kind of shine do you desire?
How much does it cost to grind concrete?
In fact, concrete grinding contractors normally charge around 0.75-2 per square foot for light concrete sanding. This makes the floor ready to install a new floor covering. over, check out the ranges for different types of glues or mastic removal:
- A thin layer of epoxy paint, VCT glue, or mastic: 1 to 1.2 per square foot.
- Thick coatings 1/8-1/4”: 1.3 to 1.5 per square foot.
- Black heavy mastic (multi-layer): 1.5 to 2 per square foot.
