Concrete Grinders Polishers. What types are there? Which one is best for you?

By Randy Wheelis Grinding, Polished Concrete

Knowing your concrete grinder types — and what they are used for — is critical for successfully completing your grinding polishing projects

There are many styles of concrete grinders to choose from and it can get both confusing and a little intimidating. Especially when trying to decide what design type is best for you and your projects.

This article will outline the basic types of concrete grinders on the market and address the positive (and negative) aspects of the most common machines.

MOST COMMON TYPES OF MACHINES

  • Single head machines.
  • Dual head machines.
  • Three headed planetary grinder/polisher.
  • Four headed planetary grinder/polisher.
  • Multi-disk non-planetary grinders.
  • Variable speed and reversible machines

SINGLE HEAD grinders

While there are exceptions, most single head machines are small and light (around 100. 300 lbs.)

And most will vary between 9” 18”, run on either 110 or 220 power.

WHERE WOULD YOU USE A SINGLE HEAD MACHINE?

They are great for smaller areas that bigger machines cannot access, edges and hard- to-reach areas like small rooms, bathrooms or offices or lightweight capacity floors.

These smaller machines are also really great for taking slight ridges and high spots out of a concrete slab. This eliminates the need for contractors to “float off” these ridges with a floor patching compound in order to prevent these imperfections from “telegraphing” or transferring through to the surface of the new material being installed.

These machines are cost-effective, lightweight and essential. EVERY flooring contractor should have a machine like this strapped to the inside of their van.

WHERE WOULD A SINGLE HEAD NOT BE THE BEST CHOICE?

Larger square footage projects are less suitable for a machine that has a single head, or a machine that is small and light in general. While t hese small machines will perform well on larger projects. the time involved (if you used a small machine only for a large area) is too great and most contractors will opt-out for a larger machine for higher productivity.

concrete, surface, grinder

These smaller machines also wouldn’t do well on floors that need grinding to a flat consistent surface. because with the smaller footprint it is difficult to get that smooth consistent cut. A larger machine like a 24” or a 32” machine will produce a much more consistently flat surface.

DUAL HEAD MACHINES

Dual-headed machines are great for quickly producing an aggressive CSP, (Concrete Surface Profile). they are easy to use and cost-effective ; and are a common choice for a concrete grinding machine, especially in the rental market.

A dual headed machine with the correct diamonds can produce a CSP of 2-3, maybe even a CSP of 4 (a rougher finish) on some concrete. This profile is great for most epoxies, moisture mitigation systems, and is a great “blank slate” for skim coating in preparation for sheet goods, VCT, and carpet.

WHERE WOULD A DUAL HEADED MACHINE NOT BE A GOOD CHOICE?

These machines are typically not a good choice if you are polishing concrete. as they tend to slightly gouge the surface and fail to give the very smooth, consistent surface necessary for a good polished concrete floor that a true planetary grinder delivers. As we will see below.

THREE-HEADED PLANETARY GRINDER/POLISHERS

Here is where we start to get into the larger, more versatile machines that not only grind the floor to the desired CSP but are effective concrete polishers as well.

These machines can be chain-driven, gear-driven, belt-driven, or even centrifugal-force-driven, depending on the manufacturer.

WHAT IS A PLANETARY GRINDER?

A three-headed planetary grinder works like this. the large drum you see in the image above operates similar to a “solar system”. T his drum will rotate either clockwise or counterclockwise. The three cutter heads are the “planets”. With all three headed planetary grinders. all three heads will rotate in the opposite direction of the main drum/plate, providing an effective, consistent cut to the concrete. The heads working in opposite directions make for a machine that is balanced and comfortably controlled by the operator.

One difference between THREE headed machines and FOUR

As mentioned, with three-headed machines all three grinding heads rotate in the same direction. On a four-headed machine, 2 of the grinding heads rotate opposite from the other two. Think of it like this: The “North” and “South” heads will turn clockwise and the “East” and “West” heads will turn counterclockwise, resulting in a VERY smooth-running machine.

Also — a very important point — many of these machines are VARIABLE SPEED! This allows you to run these machines slower when “cutting” the concrete, producing the desired CSP. then speed up the machine when you begin to polish the concrete.

Another feature in most planetary grinders is that they are reversible. they will run either clockwise or counterclockwise. This is a nice feature for many reasons.

ONE. Sometimes diamonds will actually cut better and faster when you occasionally switch directions from clockwise to counterclockwise.

TWO. When using “directional” diamonds like a lot of PCD diamonds (PCDs are man-made, big aggressive diamonds) you must run them in the direction they are designed to be used as the image below shows. And, with a reversible machine it is easy to do.

FOUR HEADED PLANETARY GRINDER/POLISHERS

Four-headed, belt-driven planetary grinders — like the Predator grinder/polisher shown above — are considered by many to be the absolute Cadillac of concrete grinder/polishers. Why? Their effectiveness. their comfort to operate, and their utterly unrivaled ability to produce a high degree of clarity and reflection when polishing concrete.

They are (in my opinion) the best, period! This, however, is not to say that three-headed machines do not do well in this regard, they actually do very well producing a great shine and clear reflection, it’s just that a four-headed machine excels at it.

SHOULD I BUY A THREE- OR FOUR-HEADED PLANETARY GRINDER?

So the next question immediately is. What’s the difference between a four-headed and a 3 headed planetary grinder?

Three-headed planetary grinder PROs

  • Three-headed machines use less tooling. So, this saves the contractor money.

Four-headed planetary grinder PROs.

Four-headed machine Cons.

When trying to choose between these two great types of machines I’d ask these questions.

“Do you do more concrete profiling to achieve the needed CSP and less polishing?” “Are you starting out in business and the cost of equipment is a concern?”

if your answer to these questions is “yes” then a three-headed machine is probably the choice for you.

But if you answer these following questions with a “Yes”.

“Do I plan to FOCUS most of my projects on polishing versus surface preparation?” “Will I FOCUS on high-value / high-quality customers and finish expectations?””Will my workload and project types support a higher quality/priced machine?”

Then most likely a four-headed machine is the best fit for you.

Power Trowels have been around for many years, they are used in the placement of wet concrete. But in recent years manufacturers have learned that the correct polishing diamonds attached to a float pan, makes a great polishing system with unheard-of production rates! While this system is NOT suited for some projects, where it is applicable, it is an awesome choice.

WHERE WOULD YOU USE A POWER TROWEL?

This system is a great choice for very large projects 20K sq. ft. and more. the reason for this is its very high production rates. this system is great for warehouses, production facilities and manufacturing floors.

WHERE IS THIS SYSTEM NOT APPROPRIATE?

Smaller, high-end, projects where wall and millwork finishes are already installed, as well as occupied spaces. the reason is that you must use a power trowel “WET” the floor must be flooded with water and polished using this “wet method ” and this method is just not practical for these types or projects.

MULTI-HEAD NON-PLANETARY MACHINES

These machines vary in size and number of heads. It’s common for this type of equipment to have between six and eight cutter heads, though there are machines with more heads and fewer. These machines have no main drum rotating, just the individual heads turn.

They are also operated differently than true planetary grinders. But with a little training, these machines can be a good option.

Like all the other styles mentioned, this type of grinder can be a good choice. or not. depending on the manufacturer. So, be sure to do your research before purchasing one.

a few more IMPORTANT POINTS

ANY MACHINE IS ONLY AS GOOD AS ITS TOOLING

Simply put, tooling selection is just as important as machine selection. You can do all your research and buy the best machine for your projects, but if you do not understand tooling, and do not use the correct tooling — in this case mostly diamond tooling — you will be unhappy with the machine’s performance.

So, do your research, educate yourself on how diamond tooling works, call your manufacturer and ask for directions from their tech-reps and trainers. Tooling and equipment manufacturers will typically have these resources available.

Here at Bartell Global, all our sales reps are very familiar with both the equipment we manufacture as well as the tooling options available for each machine. We also have a dedicated product trainer who responds to these inquiries every day. And we are by no means alone, most reputable manufacturers and distributors are more than willing to help, as we all want contractors to have a positive experience w ith the equipment we manufacture.

So, yes, there are a lot of types of concrete grinders to choose from. And, it can be a little intimidating. but with a little research and advice from Pros that have experience with grinders you can succeed! And choose the

SURFACE PREPARATION CENTER

Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as minor pits and divots, faulting and roughness on concrete pavements. This is achieved by using diamond bits to grind the surface. This also leaves a very smooth profile-ideal for thin-mil coating or sealer applications. Diamond grinding also profiles the concrete and removes contaminants from the surface.

This is achieved by using diamond bits to grind the surface. This also leaves a very smooth profile-ideal for thin-mil coating or sealer applications. Diamond grinding also profiles the concrete and removes contaminants from the surface.

Some of the advantages of a diamond ground pavement include:

Provides a smooth surface that is often as good or better than a new pavement

Enhances surface texture and friction, and there is no evidence of deleterious effects

These improvements reduce the potential for small-vehicle hydroplaning

Does not significantly affect fatigue life of a pavement

Does not affect material durability unless the coarse aggregate is a soft stone subject to polishing

May be applied only where is needed, however, spot grinding is not usually recommended

Restoring smoothness to faulted or curled concrete highways improves skid resistance

Smooth driveway approaches

Scratch Coat Grinding / Sanding

This method is achieved by attaching various sized grit sanding pads to the concrete floor grinder. It prepares, cleans and abrades existing coatings for recoat. This process removes thin layer coatings and provides texture for two coatings to bond together. This method is slow and intensive. This technique works for coatings that were recently applied and that need to be touched up with an additional coating. This type of sanding is often refered to as “Scratch and recoat”.

Troubleshooting Your Floor Grinder

Tooling and maintenance tips for concrete grinding and concrete polishing.

How can contractors ensure that they get the most out of their grinding equipment and deliver a polished concrete floor on time and to a client’s expectations?

When working on any surface preparation job, contractors want to make the most of every moment on the job site so that they can meet both the deadline and the client’s expectations. If that contractor arrives on site to grind a floor and learns that the concrete is covered, the machine doesn’t work, or it does and it damages the floor, it can be frustrating. Machine downtime can increase costs for the contractor and increase the risk of missing deadlines. The more contractors can do to prepare their machines before they arrive on site, the better.

While many flooring covering options are long-lasting, in some applications, the most durable, cost-effective and aesthetic flooring option can be the concrete substrate itself. Concrete floors are now a popular choice in a range of applications, from parking structures or warehouses to commercial facilities and residential basements. Turning concrete from a substrate intended to be covered into an appealing floor requires contractors to grind and polish the material to flatten, smooth, and remove any imperfections. Contractors regularly work with concrete, so may feel well prepared for these types of application. However, when working on a polished concrete floor contractors must take extra care. Any mistakes will be visible in the final floor.

How can contractors ensure that they get the most out of their grinding equipment and deliver a polished concrete floor on time and to a client’s expectations?

Choose the right tooling

Regular maintenance is key.

One of the most common reasons equipment isn’t delivering the expected results is that the contractor has not selected the right tooling. Every surface preparation job is different, so before starting any work, contractors should visit the site to understand what is already adhered to the concrete, the current state of the material and the desired finish. These will help determine the steps and tooling required to complete them. For example, there may be adhesives or coatings that require contractors to scrape the floor before grinding.

The desired finish will determine the concrete surface profile (CSP) required. If the floor requires a coating, contractors may need to prepare the substrate to a higher CSP so the covering will adhere.

Don’t get aggressive

If a contractor needs to remove adhesive they should grind at a lower speed, because higher speeds create friction and require higher force on the machine.

concrete, surface, grinder

No matter the required result, when grinding a floor, contractors should always use less aggressive tooling and work their way up. Starting off with a more aggressive tool to remove any bumps or thin coatings may speed up removal, but it may also damage the concrete, making it more difficult to deliver an appealing polished floor to the client. Alternatively, it’ll take time and money to fix the mistake.

Carbide chips, for example, can remove paint or left over adhesive from previous coverings, by scraping the concrete without digging into the material. Then, contractors can start using Polycrystalline Diamonds (PCDs) or other diamond tools. Starting with diamonds with a lower grit, which less aggressive, contractors can keep increasing the grit of the tool until they reach the required result. These diamonds come in three main forms — soft, medium, and hard. To match the matrix, contractors should use soft bonded diamonds on hard concrete and hard bonded diamonds on softer concrete. This ensures that contractors expose the diamonds on the tool at the correct rate to deliver the required CSP.

Troubleshooting

If the floor is properly prepared for grinding and polishing, the tools are right for the application, but contractors still aren’t seeing the results they expect, they can take other steps to make the most of the grinder.

Adjusting speed to the requirements of the job is key. For example, if a contractor needs to remove adhesive they should grind at a lower speed, because higher speeds create friction and require higher force on the machine. The more friction there is, the more heat is generated, increasing the risk that the adhesive on the floor will melt and become difficult to remove. Contractors can even add ice to the floor and wet grind to make this easier. When polishing concrete using diamonds, increasing speed adds weight to a machine and creates the friction needed to ensure the tooling stays in contact with the concrete, delivering a cleaner profile. If the tool isn’t aggressive enough, contractors can also add attachable weights to their machine. Taking time to find the sweet spot ensures contractors are working efficiently but not so fast that they skip over some of the material.

Machine issues can also cause issues or downtime once on site, so regular maintenance is key. Cleaning the underside of a grinder after any job keeps the dust from one site negatively impacting the next. Contractors can also look at the state of specific tooling on the machine they’ve chosen ahead of time.

When working on a polished concrete floor contractors must take extra care. Any mistakes will be visible in the final floor.

This may look different depending on the machine in use. For example, the Helix planetary grinder grind and scrape plate features a nylon clutch to hold tools. This ensures that if the machine does come to a sudden stop, it damages this plate instead of internal machine components, so having an extra plate on site can increase machine uptime. Alternatively, the 8274-4 grinder is driven by a Kevlar belt — while this is a strong material it can break or fall off the machine. Keeping instructions on fixing the belt and necessary tools for maintenance on site will make it easier to get the machine back up and running.

Delivering projects on time and to specification helps contractors build trust with customers and confidently pitch for larger projects. Taking the time to prepare the right machinery and tooling before the work begins, as well as knowing how to efficiently complete the work while still delivering quality can help maintain uptime, while also reducing the risk of costly mistakes.

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.
  • Check our Concrete Calculator. You can find out How much concrete do you need?

Do you want to know how much will a concrete grinder remove? Here are the answers, along with other commonly asked questions.

The beauty of choosing a full exposure aggregate of polished concrete for your space – whether residential or commercial. Is that you got a truly unique floor. No two concrete floors are the same, as it all comes down to concrete quality, technique, and aggregate amount.

However, most people don’t know how to achieve that shiny and refine style. Also, aggregate exposure ranges from minimal to open-stone exposure depending on the depth of the rocks inside the concrete and grinding.
