Concrete Grinder

It’s often best to leave Concrete Grinding up to the professionals but if you are interested in learning more about how to use a Concrete Grinder or how our team uses them than continue to read.

Step 1: Get To Know The Concrete Grinder That You Are Using

Concrete Grinders are very powerful machines and if not used correctly can be very dangerous and even deadly. Make sure you read the user manual carefully and understand all of the features and parts of the Concrete Grinder before attempting use.

If you do not feel confident, it’s always best to leave it up to the professionals or get professional training first in most cases, the manufacturer offers a free course on how to correctly operate the machine to ensure you get the best results possible and operate the Concrete Grinder safely.

What Is A “Walk Behind” Concrete Grinder Used For?

A walk-behind concrete grinder comes in all different size’s and is used to grind a variety of different products off concrete floors. Depending on how big the job is and what product you are removing as well as other factors such as the thickness of the product being removed will determine what walk behind concrete grinder should be used. Other factors may come into play such as what power is available on site and what the access is like as some of the larger machines are extremely heavy and will require generators as well as “double door entrances” due to there size.

What Is A “Hand Held” Concrete Grinder Used For?

A handheld concrete grinder is as a fast solution for smoothing out bumps and other irregularities in both horizontal and vertical concrete surfaces. It is also used for doing skirting boards, walls, corners, hard to reach areas, areas that cannot fit a walk-behind concrete grinder, touch-ups, ETC.

What Is A “Passive Planetary” Concrete Grinder?

The “Passive Planetary” Concrete Grinder is the model that is more focused on concrete grinding than concrete polishing. The passive planetary concrete grinder has three satellite discs that are not driven, they float. You can easily swap the satellite discs to turbo plugs instead of satellite discs with very little downtime.

What Is A “Active Planetary” Concrete Grinder?

The “Active Planetary” Concrete Grinder is the model that is more focused on concrete polishing than concrete grinding. The active planetary concrete grinder has three satellite discs that are driven in addition to the main disc. You can swap the satellite discs out to turbo plugs but it is not a quick change procedure like on the passive planetary model.

This is a more complicated system hence why they cost a little bit extra, but it does have a better cutting action when it comes to concrete polishing. Planetary Grinders work best on less aggressive jobs, such as polishing a concrete floor, light floor preparation, wood floor sanding instead of concrete grinding, ETC.

What PPE Should Be Worn When Operating A Concrete Grinder?

PPE (Personal Protective Equipment) should always be worn while operating a Concrete Grinder, no matter how big or small the machine is. The recommended PPE to be worn while operating a Concrete Grinder is:

– Safety Glasses, Goggles Or Face Shield
– Work Gloves
– Ear Muffs
– Dust Mask (N95 )
– Hard Hat (Commercial Work Sites)
– Safety Boots
– Sufficient Work Clothes

Understanding What Attachment Is Required For Your Concrete Grinder

With Concrete Grinders there are multiple different attachments called “Discs or Plugs” these different discs and plugs are replaceable and need to be changed depending on what you are trying to remove from the concrete. They are incredibly expensive and if the wrong disc or plug is used for the wrong surface they will get “eaten” away a lot faster costing you huge amounts of money. You must always ensure you are using the correct attachment for the job.

One of the most important parts of any Concrete Grinder is the disc or plug attachment used by the machine. These are the diamond-encrusted metal discs or stone plugs that are attached to the Concrete Grinder. These attachments are what make contact with the concrete and gradually grind it away.

List Of Different Types Of Diamond Discs & Plugs For Concrete Grinders And What They Are Used For:

TYPE: ARROW HEAD DISC / PLUG
USES: For general grinding, adhesives, paints, blackjack, epoxy, weaker carpet glue, vinyl glue, tile glue, Polyurethane, PS Glue, Rubber Back Residue, Self Leveling Screed
DESCRIPTION: Arrow Head Disc/plugs have a segment with a sharp leading edge for slicing, grinding and scrapping at the same time. This makes them aggressive, and ideal for glue removal and quick removal of thick layers 3MM and under.

TYPE: PCD DISC / PLUG
USES: For pressure-sensitive glues, cementitious glues, sticky paint, sticky epoxy, mastic, urethane, waterproofing membranes, tile beds and strong, thick adhesives
DESCRIPTION: PCD Disc/Plug’s feature extremely rough diamond particles for fast removal of thick and sticky compounds like paint, epoxy, mastic, adhesives, urethane and residues. They are more aggressive and longer-lasting than standard diamond cup wheels. They are commonly used when conventional diamond cups will not grind the material quick enough or they tend to get clogged up.

PCD Disc/Plug’s will not load up or smear the coating like a conventional diamond cup wheel but do leave a rougher finish. They are great for removing thick layers of materials over 3MM

PCD discs in the glue removal processed are used to remove 80% of the glue while leaving about 20% of the residue left. This is due to the fact that PCD discs get damaged if they grind on raw concrete, so once 80% of the glue has been removed move onto the next section. Once you have finished grinding the whole area with PCD’s swap back to arrow head discs to clean up the remaining 20% residue.

TYPE: General Purpose Disc
USES: For general purpose grinding, also great as a “finishing disc”, removing minor bumps up to 3mm, removing minor imperfections.
DESCRIPTION: General purpose discs are designed for general purpose grinding, and flat grinding. They are ideal for aggressive removal of imperfections and minor concrete bumps. The double row gives them a smoother finish and a very long life. They are also great for cleaning up the concrete after use of an arrow head or PCD disc to give it a cleaner finish.

Different Concrete Grinders may have different ways to attach the disc or plug depending on the size of your machine. Please read the manual for how to attach the discs or plugs if you are unsure. In general, the plugs just slide it and can be tapped out using a hammer. While the discs are normally screwed on, or click in with an attachment pin or attached with another method.

Discs And Plugs For Concrete Grinders – What Is The Difference?

Each disc or plug for concrete grinders is suited to a different stage in the concrete preparation process – “Plugs” are for the heavy-duty grinding, while “discs” are for finer work.

As you progress with your concrete surface preparation, you will need to switch plugs and discs. Switching plugs is very easy (we always recommend you wear gloves). Get a hammer and tap it on the plate near the plug and the plug should fall out. To put plugs in, just push them with a bit of force and they will bind in.

When it’s time to change from plugs to a disc, take the plug out and put in the magnetic plug that comes with the discs. Next, put the insert through the disc and then attach the disc to the magnetic plug. (When changing discs back to plugs, make sure you take magnetic plugs out).

To change the discs on the smaller concrete grinder/edger you’ll need to find the locking pin on the side of the machine to lock it in place. Once locked, take a spanner and use it on the centre nut to remove the disc. Replace with the new disc and tighten up again.

Arrow Head Discs VS PCD Discs

If the coating you are attempting to remove from a concrete slab is thicker than 3MM or is quite sticky you are normally better off using a PCD disc over an arrow head disc. Arrow head discs will run into the following issues if you try to use them on sticky coatings or thick coatings:
– the disc/plug will have issues with overheating
– The arrow head will clog up frequently
– It will struggle to break through a coating thicker than 3MM and will take a lot longer than a PCD would.

It should also be noted that every hour its best to check the disc/plugs so that you can scrape off and clean any glue or coating residue build-up on discs and plugs. you can even sand them if you have any sandpaper. As keeping the discs/plugs clean will keep them running cooler and a lot more efficiently.

How To Improve Concrete Grinding Speeds & How To Expose The Diamonds On Your Blades & Plugs For Increased Performance

Method 1 – Wetting the concrete before concrete grinding helps to expose the diamonds a little more. Try to scratch open the surface first with a few light grinds while dry, then apply water and give it a couple of minutes to soak in. Broom off the puddles and remaining water to leave the surface wet. This process makes the dust a little heavier which cuts the matrix more to expose more diamonds to improve performance when grinding hard concrete. The dust will appear to be the same as if the water has done nothing, but grinding will be more productive. Repeat this process for each new cut.

Method 2 – Lowering the effect of the dust extraction, or vacuum: When we suck away all the dust from the concrete grinding process this changes the way the segment erodes away and in turn the amount of segment poking out of the segment. By not sucking away all the dust from under the concrete grinder when on hard concrete will allow the dust to erode the matrix and the diamond will protrude out of the matrix and scratch the concrete properly creating a faster grind. In turn, sucking away all the dust produced can slow the wear of your diamonds on soft concrete.

Understanding Your Diamond Blades & Plugs And How To Pick The Right One For The Job

Diamond tooling selection is crucial for making a profit and not going backwards on a job as diamond discs and plugs are extremely expensive. Using the wrong disc/plug for the job could cost you thousands! When selecting your diamond disc/plug you need to understand the following information:

Bond

Each diamond is set in a metal bond, the metal bond breaks away exposing the diamond, which in turn cuts the concrete. bond is critical when it comes to wear rate and performance on harder concrete slabs. Bond itself suspends the small ‘grits’ of polycrystalline diamond so that they do not fall out onto the surface being ground. The bond wears away to allow the diamond to be exposed.

This is required to sharpen the diamond to allow it to cut the concrete. Basically, as the diamond is dragged across the surface of the floor it is slowly blunted by the force of friction. At the same time, bond wears around the diamond exposing it more and more. Once the exposed diamond reaches a certain point, it splits and shatters creating more sharp surfaces which continue to cut.

The rate of exposure the diamond will require to stay sharp will depend on how hard the concrete is. In the case that the concrete is hard then the diamond will blunt quickly and require constant splitting/fracturing to ensure it stays sharp. Of course, the downside to the need to quickly expose diamond is the increased wear rate on the disc or plug.

Alternatively, where the concrete is soft or very gritty the opposite problem exists. Because grit and dust are abrasive to the bond it increases the speed of wear. This allows the diamond to become exposed, splinter and re-sharpen well before it blunts. While this does ensure maximum concrete grinding speed, it reduces the lifespan of the diamond disc or plug. In this case, a hard bond product will ensure wear is slowed to a more reasonable level.

A SOFT bond diamond disc or plug is more aggressive, but it will wear out quickly especially on soft concrete!

A HARD bond diamond disc or plug will wear slowly, but it will cut faster on soft concrete.

Soft concrete is more aggressive compared to hard concrete. So when selecting the diamond disc or plug we do the opposite:

You can obtain a “Moh’s Hardness Test Kit” online which allows you to scratch the concrete slab to check what type of diamond you should be using on the current concrete surface that you are working on. As it’s important to remember EVERY concrete slab is different.

With SOFT concrete – We use a HARD bond diamonds disc or plug.

With HARD concrete – We use SOFT bond diamonds disc or plug.

Segments

Discs & plugs have a series of blocks called ‘segments’ attached to them by way of high-temperature solder. These segments are the component of the diamond disc and plug that does the concrete grinding. Once these are worn completely away, the disc or plug will no longer be usable. Discs with fewer segments will be more aggressive. While discs with more segments on the wheel will deliver a smoother surface/finish.

The MORE segments a disc or plug has the LESS aggressive it is.
(This blue disc has A LOT of segments, making it a less aggressive disc)

The FEWER segments a disc or plug has the MORE aggressive it is.
(This red disc has VERY FEW segments, making it a very aggressive disc)

What Does ‘GRIT’ Mean?

The final piece of the puzzle is GRIT. Grit is generally the easiest component of the disc/plug to understand. Grit is used as a reference to describe the finishing qualities of the diamond disc/plug. The lower the number, the larger the piece of diamond (coarser grit). The higher the number, the smaller the piece of diamond (finer grit). Just like sandpaper, as the grit becomes smaller the finish becomes smoother. Generally in concrete grinding, 30 or 40 grit is about the coarsest required (Usually, 60-80 grit discs/plugs are used in the process of concrete polishing and not concrete grinding)

Most diamonds are #16 grit – Which is very aggressive for cleaning up concrete slabs.

But they go all the way up to #150 grit – Which is very fine for polishing up concrete slabs.

You will mostly use #16 & #30 grit – For removal and prep work on concrete, anything above that is heading towards polishing the concrete slab.

(Low Grit Number) – Are more for faster removal of concrete and for harder concrete.

(High Grit Number) – Are more for smoothing, polishing and touching up.

Concrete surface

What concrete hardness means for the concrete grinding industry is that the surface you are grinding will be either soft or hard. A 25 MPA concrete is very soft generally rain damaged and powdery and something that is say 50 MPA which is very hard, generally curing compound applied or densified.

It’s really hard to tell until you start grinding the concrete.

We recommend starting with a hard bond diamond and see if the grinding is quick enough.

If too slow or not cutting at all, change to a soft bond but check the wear on the diamond after 10 mins or to make sure it’s not wearing too quick.

It is commonly known that every concrete slab is different, even areas within the same slab can vary from easy to grind too hard to grind. Here we describe what is actually happening and why we need different grades of diamonds and grades of the matrix for the concrete grinder to work effectively:

The main thing that causes a diamond to stop cutting is that the matrix that holds the diamond chips is not wearing out fast enough to keep fresh diamonds exposed and the diamond chips lose their edge. This means that the diamond chip ends up not protruding out of the segment and therefore rounding off and not cutting the concrete or stone. Hence, the grinding process slows down a lot. Faster diamonds or diamonds that cut faster have a feature common to them. Changing the following variables within the disc or plugs and segments mounted on them creates a faster cut:

– Diamond Chip Size:
Mostly there is #16 Grit through to #150 Grit sizes available.

– Number Of Segments:
Using a diamond disc with fewer segments means that there is more pressure per segment applied to the cutting surface. This wears the matrix faster and exposes the diamond chips.

– Softer Matrix That Holds The Diamond Chips:
This means that the matrix will wear at the same rate as the diamond chip or slightly faster meaning there is always a fresh edge to the diamond itself.

There Are A Few Things You Can Do To Speed Up Concrete Grinding

Here are a few tips that you can try: (You can try more than one of these at a time to grind faster).

Turn Your Dust Extraction Down:
– This will leave the dust from the grinding process under the head of the grinder and this creates wear to the matrix of the diamond segment which exposes the diamond chip again)

Add Weight To The Head Of The Concrete Grinder If The Power Available Permits:
– This will put more pressure on each segment and wear out the matrix to expose the diamond chips.
– More pressure per segment helps wear the matrix at the same rate as the diamonds wear.
– The extra weight does little to the wear factor of the diamond chips.

Use “Soft Bond” Discs With Fewer Segments To Overcome The Issue:
– The softer bond refers to the matrix, not the diamonds. the result of a softer bond is that the matrix wears out faster and keeps the diamonds fresh and exposed.

Throw A Little Bit Of Sand (Or Dust From Previous Grinding Work) Onto The Slab:
– This is where the matrix away which will increase the chance of opening up the diamonds again.

Add A Misting Of water To The Concrete:
– This will make a slight paste between the diamonds and the concrete which will increase the chance of opening up the diamonds again.

Grind Or Cut On A Soft Concrete Slab To Open Up Fresh Diamonds:
– Using a known soft slab or even a paver can open the diamonds up again to they have a fresh edge.

Reverse The rotation If That Function Is Available On Your Machine:
– Reversing the rotation of the machine can change the dynamics of the way the diamonds are being worn out and give a fresh edge to the diamonds.

Concrete Grinding Shoes?

Different companies may have different attachments for their Concrete Grinders. So if your Concrete Grinder doesn’t fit a “Concrete Grinding Disc” or a “Concrete Grinding Plug” than it will most likely fit a “Concrete Grinding Shoe”.

Why Is There Weights On My Concrete Grinder?

– What are the weights on my concrete grinder used for?

– When should I change the weights on my concrete grinder?

– What does changing the position of the weights on my concrete grinder do?

POSITION 1 – Normally the weights will be at the back of the machine located at the bottom (position 1) this is to keep power consumption down on the machine and to avoid the machine running at over 100% which would cause an overload or cut out. Although if the machine is not running at the full performance that it can you can move the weights to the front of the machine instead of the back (position 2)

POSITION 2 – By moving the weights to the front (into position 2) it will increase the performance of the concrete grinder and the diamonds by giving it more weight and pressure. ALTHOUGH this can only be done if the power source and the concrete grinder can handle it!

You have to keep an eye on the gauge. Which is located on the “HVA Meter” this meter will show you the performance of the machine while it’s running. If it says its running at 100% that’s fine. If you put the weights on the front of the machine (position 2) and it says it’s running at 110% you know you’re overloading the machine so you need to put the weights on the back (position 1) instead of the front (position 2).

Do not push the machine over 100%. If it’s running at 70% you can increase its performance by moving the weights to the front of the head (position 2). But if the machine is running at over 100% you need to move the weights to the back of the head (position 1) to reduce the performance to stop an overload occurring.

POSITION 3 – If the machine is overloading (Running at over 100% and cutting out/switching off/blowing your power) non stop even with the weights in (position 1). You have a third option (position 3) move the weights to the far back to reduce the weight even more on the head of the concrete grinder. You can place the weights on the far back of the machine to help it lift the head off the concrete slightly to reduce how much pressure the machine is putting on the concrete and diamonds.

This will reduce power consumption & power of the diamonds by placing the weights into (position 3) on your concrete grinder which will reduce the weight on the head of the concrete grinder. This is used for softer concrete or for when the machine is still running at over 100% and keeps switching off.

– How do I change the weights on my concrete grinder?

Simply lift up the weight and slot it into one of the other positions, depending on the model of the concrete grinder. some may screw in, bolt in, or simply just sit there. For the satellite models, they simply pull up and slot back down.

Understand What The Power Requirements Are For Your Concrete Grinder

The stronger the Concrete Grinder, the more power is required to operate it. So always make sure you have the correct cable as well as cable length: When using a 10 AMP Power Cable to power a walk-behind concrete grinder, its important to remember that your cable should be 15 metres long MAX. otherwise it will trip out your power constantly and won’t power the concrete grinder correctly. In this situation, it’s best to hire a 16 KVA generator as well as a heavy-duty 10 AMP – 15 Metre power cables to ensure the machine is getting enough power.

– 10 AMP Power Cable (Your standard Australian power cable used for most household appliances, they are also used to power handheld and low power 240v walk behind Concrete Grinders)

– 15 AMP Power Cable (This cable looks like a 10 AMP power cable but the bottom pin is larger. 15 AMP power cables are used to power mid-range Concrete Grinders that require power sources over 240v)

– Three-Phase Power Cables (This is a heavy-duty large 4 spike cable used to power heavy-duty commercial Concrete Grinders)

Plan What Dust Control Method You Are Going To Use With Your Concrete Grinder

Its always recommended to use sufficient dust control methods while using a Concrete Grinder this usually involves attaching a high powered commercial vacuum or commercial dust collector directly into the Concrete Grinder (which is located at the back of a walk-behind Concrete Grinder or normally an attachment is purchased for a handheld Concrete Grinder to allow you to plug a vacuum or dust collector directly into the Concrete Grinder).

Another option is wet Concrete Grinding the wet process is the oldest way of Concrete Grinding and polishing concrete. Many people prefer it for the simple reason that it has been around the longest, and they learned to grind or polish concrete using this method. It’s also a simple way to control dust if a dust extraction machine or commercial vacuum isn’t able to be used or isn’t available.

The Advantages Of Wet Concrete Grinding Are:

– Almost no dust goes airborne thus reducing the need for respirators or dust collectors and vacuums.
– The diamond discs/plugs run cooler.
– You can use the amount of water to govern the rate of wear on the diamonds.

The Disadvantages Of Wet Concrete Grinding Are:

– Makes a horrible mess often having to have another machine sucking up the slurry or additional labourers sweeping it out of the way.
– The floor must be dried for a long period of time after wetting to ensure a moisture-free substrate is achieved before any recoating or reinstallation of flooring systems.
– The concrete dust slurry will often stick into the pores of the concrete and when dried and then coating applied it cant stick to this dried slurry causing debonding issue with your new coating or flooring system.
– Disposal of concrete dust slurry water is often restricted more than dust and can be annoying to handle and dispose of.
– The Concrete Grinder becomes very dirty and has to be cleaned after use to maintain it and often needs to be cleaned on the job if its a large area.

The Advantages of Dry Concrete Grinding Are:

– The job is much easier to clean as well as keep clean if you need to do a second pass with the grinders.
– No slurry issues and the frustration of dealing with it.
– The surface is dry and ready to vacuum and coat or install a new flooring system immediately.
– You can see the results immediately while your Concrete Grinding.
– The Concrete Grinder is a lot easier to maintain and components generally last a lot longer.

The Disadvantages Of Dry Concrete Grinding Dry Are:

– Dust is a health hazard as well as whatever else goes into the air, depending what you’re removing from the concrete such as magnesite residue, or asbestos vinyl residue which means the dust in the air could contain asbestos.
– The dust must be controlled with sufficient equipment and PPE to prevent inhalation and respiratory health risks.
– Dust can be hard to collect using cheap vacuums and require special purpose-built dust collectors to maintain airflow without the filter constantly getting blocked from the concrete dust.
– Usually, high powered commercial vacuums or dust collectors are needed.
– If the incorrect tooling is used Concrete Grinders can overheat easily and cause glazing.

Why Do I Need A Concrete Grinder?

How Does A Concrete Grinder Work?

Concrete Grinding involves using rotating diamond teeth discs or plugs on specialized machinery to level, smooth or cleans the surface of a concrete slab to allow re-installation of a new flooring system. Or simply have a clean, level and smooth concrete floor.

Concrete Grinding is usually carried out by large floor grinding machines that have diamond-encrusted cup wheels installed on a spinning disc. These diamonds make contact with the concrete at high speeds and gradually grind down the concrete or glue residue, etc.

It doesn’t matter if you’re using a small handheld Concrete Grinder or a bigger walk behind Concrete Grinder – they work the same way. The head rotates, grinding the surface of the concrete beneath, and different attachments must be used to get you the results that you want.
