What Is Wall Grinding?

A Hand Grinder can come in many configurations, the most common being a Hand-Held Angle Grinder. This is a specialized tool for countertops or worktops. There are also purpose-built Floor Concrete Grinders and Hand Held Concrete Grinders that are used for Concrete Grinding and Concrete Polishing of marble, granite, and concrete floors.

Dust-Free Wall Grinding using an abrasive tool, like a Walk Behind Concrete Grinder or a Hand Held Concrete Grinder, in combination with a diamond disc or plug attachment combined with a commercial silica dust extractor on rough concrete surfaces to reveal a smooth finish to prepare your concrete to have a new flooring system or coating applied.

Is Wall Grinding Required?

Sometimes, after certain flooring systems (such as Tiles) or coatings (such as Epoxy or Waterproof Membranes), and the skirting boards have been removed, there may be some form of residue left on your wall’s skirting area. This residue must be removed before the re-installation of any coating or new skirting board system. Our team will remove all residue with the use of a high-powered Dust-Free Hand Grinder.

The Dangers Of Silica Dust In The Wall Grinding Industry

In our workplace, we hang a “Silica Dust Warning Sign” to let our clients know that it is not safe to enter this working area while we are Wall Grinding without wearing the appropriate PPE (Personal Protective Equipment) that our employees are wearing. Even though we are using high-powered dust extractors to handle the silica dust that our Hand Grinder produces, small amounts may still escape from our Wall Grinding and enter the air. This is why our employees wear P2 dust masks.

Please do not ever attempt to enter the workspace without a P2 dust mask while our employees are Wall Grinding during your job. Your cooperation is greatly appreciated.

Some dust particles can be so small that they are not visible; these are referred to as respirable particles. Respirable silica dust particles are those that are small enough to breathe in and penetrate deep into the lungs causing permanent damage that can lead to serious illness or death. Silica dust is also linked to the development of auto-immune disorders and chronic renal (kidney) disease.

Crystalline silica dust can be harmful when it’s inhaled into your lungs over a long period at low to moderate levels, or short periods at high levels.

When crystalline silica dust is inhaled, it can cause silicosis, a scarring of the lungs. Silicosis is a serious and incurable disease, with symptoms including shortness of breath, coughing, fatigue, and weight loss. In severe cases, the damage caused to the lungs by silicosis can require a lung transplant or may lead to death. Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing.

Breathing in silica dust can also cause other serious diseases, such as:

– Lung Cancer
– Kidney Disease
– Autoimmune Diseases, such as Scleroderma

Construction and demolition employees can be at especially high risk of developing these diseases.

Can You Grind A Uneven Slab?

Yes, we can grind an uneven concrete surface to level it (depending on the variations). Our professional Wall Grinding team can quickly identify raised areas, often by pouring water on the floor or using laser measuring devices. Once these areas have been identified, our team will use a Hand Grinder to create a smooth, clean, and level surface.

If your concrete slab has variations larger than 3mm this may affect our ability to be able to successfully leave a smooth, clean, and level surface. A standard Hand Grinder that works on residential power (240V) can only grind up to 3MM variations in your concrete slab. Variations larger than that need to be fixed with:
– Floor Levelling Compounds
– Concrete Scarifiers
– Concrete Shot Blasters
– High Powered Concrete Grinders (15AMP or 3PHASE)

How Deep Can We Grind With A Concrete Grinder?

The Wall Grinding process is also used to level very small highs in concrete slabs up to 3 MM, grind expansion joints level, and prepare surfaces for the application of levelling compound or for the re-installation of floor coatings or floor coverings such as Carpet Tiles, Vinyl, Tiles, Timber Flooring as they all need a clean smooth and porous slab to bond too.

Hand Grinders often only remove a thin layer of material from the surface of workpieces per pass. Typically, diamond grinding tools only remove between 0.25 MM to 0.50 MM of material for a maximum of 3 MM.

Industrial or heavy-duty Concrete Grinders with correct diamond tooling or other tooling can grind depths of up to 6 MM of material from the workpiece.

After this point, a ‘Concrete Scarifier‘ or ‘Concrete Shotblaster‘ must be used to get further depth

Regarding how many MM can be taken off, please follow the guide below:

Wall Grinding – Residential – (3MM MAX)
Wall Grinding – Commercial – (6MM MAX)
Coating Removal – (6MM MAX)
Bump Removal – (8MM MAX)
Coating Removal – Double Layer – (12MM MAX)

Why Is Wall Grinding Important?

Wall Grinding is important before almost any flooring system being installed (apart from the carpet), floorboards, tiles, vinyl, lino, slate, epoxy, paint, waterproofing membranes, parquet, floor levelling agents, etc., being installed. will all require Wall Grinding before installation.

The concrete beneath can be rough and uneven and even have paint, epoxies, glues, cement residues, bumps, or other residues left on it. Making installing various flooring or paints, epoxies, etc., on top impossible (or fail quickly)

This is why the contractor/business who is installing your new flooring system, floor levelling agent, or coatings. Contractors and businesses will refuse to give you any warranty on the job unless you have your concrete ground first.

Once Wall Grinding has taken place and the smooth surface is revealed, installing any alternative flooring option is easy.

Preparing the floors before the application of a new flooring system, epoxy, or paint is the single biggest way to ensure the longevity of your new flooring system or coating. It is especially important if the floors are going to be polished, as the quality of the concrete will show through.

What Is A Hand Grinder?

A Hand Grinder can come in many configurations, the most common being a hand-held Hand Grinder or hand-held Angle Grinder and A Hand Held Concrete Grinder but it may be a specialized tool for countertops or worktops. Angle Grinders and Hand Grinders are small and mobile and allow one to work on harder-to-reach areas and perform more precise work.

There are also small, medium, and large walk-behind Concrete Grinders for tackling larger projects. There is even riding on Concrete Grinders for industrial projects.

All Concrete Grinders use some sort of abrasive to grind or polish, such as diamond tools or silicon carbide. The diamond tools used for grinding most commonly are diamond grinding cup wheels, other machines may use diamond segments, mounted on various plates, slide-on diamond grinding shoes, and for polishing are usually circular Resin diamond polishing pads.

The use of diamond attachments is the most common type of abrasive used under concrete grinders and comes in many grits that range from 16 grit to the high thousands, although 3,000 grit is considered by the industry as the highest shine possible to apply to a floor surface.

Is A Concrete Grinder Worth It?

A Concrete Grinder is an ideal solution for concrete restoration projects like removing coatings, residue, stains, and other unsightly imperfections. You may also use a concrete grinder to even out a surface or prepare the concrete for an overlaying finish.

Concrete Grinders, Concrete Scarifiers, and Shot Blasters prepare concrete surfaces, but they operate differently to deliver various results. A Concrete Grinder is an excellent choice for smaller projects because it can remove shallow layers of concrete while providing enough precision and smoothing abilities to polish surfaces or remove coatings as well as to prepare the surface for reapplication of Flooring Systems, Coatings and Floor Levelling Compounds.

Why Do I Need Wall Grinding?

Why do you need Dust-Free Wall Grinding? Wall Grinding is used for a large range of different reasons. Wall Grinding can enhance safety by transforming a rough and damaged floor into a smooth, hard surface, reducing the risk of injury for homeowners and visitors. Additionally, when applied to driveways, it can create a quieter and more slip-resistant surface for vehicles.

If you are looking to lay any floor covering to a concrete slab, you must first check that the concrete slab is clean, perfectly level with no minor bumps (even 0.1mm can be an issue), and ready for the installation of the new flooring system that you have chosen EVERY flooring system except for carpet will require “Floor Preparation” before installing your new flooring system (Excluding carpet).

Your new flooring system needs a clean, smooth, and porous slab to bond to. Any glue or cement residue or any minor bumps in the slab left between the concrete will affect the quality and durability of the new floor covering that is being installed and may result in the flooring system that you are installing failing.

Floor installers (all major companies) will not give you a warranty or simply won’t do your project if you haven’t had the Dust-Free Concrete Grinder come in to clean up your concrete slab as they won’t be able to give you a warranty on installing your new flooring system. Dust-Free Wall Grinding is necessary to remove any glue residue and to level your floor to enable a clean installation of your new flooring system.

Dust-Free Wall Grinding is also necessary to remove any trip hazards if you wish to use a concrete slab as your subfloor. It is especially important if the floors are going to be polished, as the quality of the concrete will show through.

Dust-Free Wall Grinding the floors before the application of tiles, floorboards, vinyl, lino, slate, pebblecrete, parquet, laminate, epoxy, waterproofing membranes, floor levelling products, paint, etc., is the single biggest way to ensure the longevity of the floors as well as to ensure that you get your warranty from the installer/company that you chose to install your flooring system.

If you “skip“ the process of “Floor preparation” by not doing Wall Grinding, companies have the right to NOT give you any warranty on the installation of their flooring system that they have installed. So if it fails within even 7 days, it is YOUR issue and not theirs, and you will NOT get a refund / free repair/replacement or anything like that, so you could end up wasting tens of thousands of dollars purchasing and installing your new flooring system, only to have it fail within a short period because you chose to skip the Wall Grinding or floor levelling (also known as floor preparation) process. This is why “Floor preparation” is so important.

The team we provide for you are experts in their field at removing floor coverings, adhesives, and compounds that make the surface uneven and difficult to reinstall a new underlay or flooring system too.

Our service is designed to provide a completely smooth and clean surface for our customers to do what they want. Our friendly team of experts is ready to assess your situation and consult with you on the best way to proceed with your Grinding Concrete Floor project.

How Does Wall Grinding Work?

Wall 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.

There are many different types of diamond cup wheels, which will have various effects. Generally, cup wheels are measured in grits. The higher the grit ratio, the finer finish it will leave on the concrete. For a more polished effect, a cup wheel with a high grit ratio would be used.

What Is Wall Grinding Used For?

Wall Grinding removes irregularities and imperfections from a concrete surface using an abrasive tool with a diamond attachment. This may include levelling and flattening the surface for enhanced durability. With Hand Grinders, you can quickly level and smooth a rough surface.

Over time, concrete floors become scratched, and the coatings wear off and delaminate, impacting the floor’s smooth surface. Because the concrete further down might still be of good quality, Wall Grinding Concrete is the best way to improve the appearance of your concrete floor. The Wall Grinding procedure removes the damaged top layer of a concrete floor or coating, leaving a brand-new surface ready for the re-installation of a new coating, flooring system, or polished concrete floor.

TYPICAL USE OF Wall Grinding EQUIPMENT
– Remove old floor coatings and old flooring surfaces, including old paint or glue
– Prepare the surface for polishing, staining, or re-coating
– Create a level flooring surface to allow the re-installation of a new flooring system

TO RESTORE CONCRETE SURFACES
Use Wall Grinding to remove all imperfections and inconsistencies in your concrete floor to gain a smooth and usable surface. Restore old and worn concrete slabs to their former glory.

TO REMOVE PAINT, EPOXIES AND OTHER COATINGS
Wall Grinding removes paint, epoxies, and other coatings from concrete floors. The Concrete Grinder rubs against the top layer of the floor, leaving nothing behind but a smooth, good-as-new surface.

TO INSTALL OTHER FLOORING OPTIONS EASILY
Wall Grinding can be seen as Floor Preparation when you’re looking to install flooring options such as carpets or tiles.

What You Need To Know About Wall Grinding

Wall Grinding is extensively used because the concrete beneath your old flooring system can be rough and uneven, have a lot of glue & adhesive residue left on it from the previous floor installation system that was removed, and even have paint or epoxies on it. Making installing various flooring on top of it difficult or impossible without the new floor failing.

It is extremely important to remove any adhesive previously laid on the floor as well as make it clean, level, and smooth before you reinstall a new flooring system to make sure that your new flooring system is installed correctly.

Wall Grinding will always produce a large amount of very hazardous dust, which is why specialized equipment is needed to reduce the risk and damage to your health as well as the workspace. Our team uses the highest quality personal protective equipment as well as dust extraction equipment to offer a near-dustless workplace experience*.

Why Is A Wall Grinding Service Necessary?

Many commercial facilities and residential homes use concrete flooring these days instead of hardwood, laminate, tile, or vinyl. Some common places where Polished Concrete is being used are retail stores, office buildings, car dealership showrooms, warehouses, hotels, and restaurants. There are a few reasons for this:

– Wall Grinding your concrete slab to maximize the life of your new flooring system or paint, epoxy, waterproofing membranes, etc

Before the application of tiles, hardwood, vinyl, lino, carpet tiles & direct stick carpets, epoxies, stencil concrete, waterproofing membranes, paints, etc… Wall Grinding Concrete is the single biggest way to ensure the longevity of the new installation, applying a new glue to old glue, for example, will almost always fail within a short period, but if you remove the old glue, the flooring system would last 10-25x longer instead.

– Wall Grinding can be used to level your concrete floor and remove minor bumps.

Wall Grinding Concrete is used to “level” your concrete slab before installing your new flooring system as some flooring systems cannot be installed on uneven concrete slabs such as vinyl, lino, laminate, floorboards, tiles, etc.

– Wall Grinding can be used to remove old glue, tile residues, paint on concrete, epoxy floor removal, or waterproofing membrane removal before attempting to install new glue, paint, epoxy, waterproofing membranes, tiles, flooring systems, or Floor Leveling agent. Otherwise, the new one will not bond correctly and will fail quickly after installation.

Its also important to remove any previous glue, cement, paint, waterproofing, epoxy (etc.) residues on your concrete slab before re-applying any or before re-installing anything onto a concrete slab that will need to “bond” to the concrete slab as it will not bond correctly to an old coating of glue or paint or tile screed or cement residues, which is why it should be removed with Wall Grinding so a new layer of paint or glue can be applied for example.

– Floor installers and floor installing companies have the right not to give you a warranty or simply will not do your project if you haven’t had the Concrete Grinder Service come in to clean up your concrete slab.

As they won’t be able to give you any warranty on installing your new flooring system, epoxy, paint, waterproofing membrane, etc., which will often result in a “fair trading dispute” between the client and the installer or the company selling and installing the product due to the high chance of the installation failing quickly.

They will often demand you Concrete Grind your slab to ensure that their installation holds up to the warranty that they are providing you as well as to make sure that it follows the guidelines of the installations recommended by the companies that produce the products that they install, incorrectly installing a flooring system or other product will often lead to quick failure of the system if Wall Grinding has been skipped, this is why no warranty will be given, or they will refuse to take on your project.

– Wall Grinding is also used to remove any trip hazards. This is extremely important in workplaces, and your home as well as to reduce any accidents from ever happening which may result in injuries!

– Wall Grinding is often used to remove trip hazards; this is a simple solution to prevent a dangerous accident from occurring, such as someone hitting their head in your workplace by accident.

– Polished Concrete is easy to clean and a simple solution for commercial areas.

It is a great option for people with allergies, as concrete doesn’t harbour dust and dirt. All that is needed is weekly mopping with soapy water. Concrete can be polished as well to help with these issues, so Wall Grinding is required before Concrete Polishing It costs less long-term to maintain than other floor coverings.

A concrete floor that has been Polished and maintained through the years can last a century or more. Polished Concrete also never has to be waxed. Highly Polished Concrete can reduce energy demands because a Polished Concrete Floor can hold indoor temperatures longer.

– Concrete can be decorative. The use of concrete isn’t just a medium for construction these days. You can add texture and colours to concrete to make it look like brick, stone, slate, and other flooring products such as Stencil Concrete, Epoxy Flooring as well as Polished Concrete

What Are The Advantages Of Grinding Concrete?

– Restore Concrete Surfaces

Grinding Concrete removes all imperfections and inconsistencies in the concrete, resulting in a smooth and usable surface. Old and damaged concrete surfaces can be restored to their former glory and used for years and years to come.

– Remove Paint, Epoxies, Dirt, Glue Residue, Waterproofing Membranes, Adhesives & Sealers

Grinding Concrete removes paint, epoxies, dirt, glue residue, waterproofing membranes, adhesives & sealers, and other remnants left on the concrete. The Concrete Grinder rubs against the top layer of the floor, leaving a smooth surface.

– Easily Install New Flooring Systems Without Failure (Tiles, Floorboards, Carpets, Vinyl, Lino, etc.)

Once the Wall Grinding has been completed and the smooth surface is left, any type of flooring option can be installed with ease. Floor preparation is key to the longevity of any kind of flooring option.

– Perfect For Warehouses, Shops, Offices, etc.

Is There Magnesite Flooring In Your Property?

If your home was built in the 1920s – 1980s, likely, your home (Especially unit blocks in NSW) could potentially have Magnesite Flooring. Magnesite is present below a flooring system such as carpet. Magnesite is a product used as a noise preventative and a Floor Levelling agent.

Magnesite Flooring absorbs moisture (particularly in areas prone to moisture such as external walls, doorways, around shower recesses, near windows, laundries, etc.) Unfortunately, once Magnesite Flooring absorbs moisture it starts a chemical reaction that will cause Concrete Cancer over long periods.

Because your Magnesite Flooring was laid 40 – 100 years ago, it has likely absorbed moisture over the many decades that it has been trapped under your flooring system and it has most likely started to break down and lose its strength making it an unsuitable Floor Levelling product that it once was, as well as very hollow, which destroys its soundproofing.

The best thing you can do to prevent further damage to your property and the concrete slab is to remove it ASAP. Magnesite Flooring consists of Magnesium Oxychloride, which may contain asbestos.

Since it is a health hazard and a major safety risk in NSW, if you remove your flooring system and find out there is Magnesite under it.

YOU MUST remove your Magnesite Flooring for the safety of you and everyone else in your unit block.

Strata may pay to remove your Magnesite Flooring as it is considered “Common property”. Magnesite Flooring can cause Concrete Cancer which is a major risk to everyone’s safety as well as the successful reinstallation of your new flooring system.

NO company will give you any form of warranty or insurance on any flooring installation job on a magnesite floor, which is another reason why it should always be removed.

Is Wall Grinding Dangerous?

Yes, Wall Grinding is dangerous.

Wall Grinding without the correct PPE and power tools/equipment will create a harmful silica dust environment; it’s also possible to be injured by tools as well as injured from the Wall Grinding process.

– SERIOUS INJURIES: Sometimes, Tiny pieces of Concrete can go flying in the air during the Wall Grinding process; this can accidentally hit your eye, causing serious damage, if not blindness. The tools required to perform this task are also dangerous to use for people who are not highly skilled in using these tools.

– ACCIDENTAL INJURIES: It’s easy to look up a guide on what tools to use, but injuries often occur from a lack of knowledge of how to use these tools safely.

– PERMANENT LUNG DAMAGE: Inhaling dangerous silica dust by not using the correct PPE and Dust Extractors can be deadly.

The longer silicosis goes without treatment, the more likely it is to develop a complication. Because the disease affects the immune system, silicosis patients are vulnerable to developing tuberculosis, lung cancer, COPD, and kidney disease.

• • Lung Cancer.
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Kidney Disease.
  • Autoimmune Disease.

Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.

Is Wall Grinding Hard?

Yes, Wall Grinding can be a difficult and time-consuming project, and the challenges often remain hidden until the project is underway. Depending on the installation method and how the flooring system or coating has been installed.

If you have a Wall Grinding job that is over 10 square metres, it is considered a hard task that will be expensive and frustrating to attempt to do yourself. It’s often cheaper to hire a Wall Grinding contractor than to hire the tools, PPE, and other equipment required to attempt the project yourself.

There are several different installation methods when it comes to flooring systems and a huge range of different factors when it comes to floor coatings. We only recommend attempting Wall Grinding yourself if the project is under 10 square metres and you have the appropriate tools, PPE, and dust extraction equipment.

Wall Grinding equipment can be incredibly hard and frustrating to use. At Wall Grinding Sydney our team has specialised for years in the field of Wall Grinding Concrete.

Wall Grinding is normally best left up to a specialist team, such as ourselves, with the proper knowledge and equipment to do the job correctly while ensuring a smooth result and making sure the job is done correctly.

Floor Coatings can have a huge range of different factors which can make it more difficult or easier to remove. Wall Grinding is one of the most difficult services. Wall Grinding can be incredibly hard to learn and incredibly dangerous without the proper Hand Grinder and safety equipment.

Even if you head down to your local shop and hire a powerful Concrete Grinder. If you get the wrong diamond and you are not educated on how to use the equipment, you could end up spending a huge amount of time and thousands of dollars by mistake while attempting to do the project yourself.

Even if you do remove the coating, you may have ruined your concrete slab in the process and end up spending more money than if you hired a professional Wall Grinding expert.

We’ll get your job done in one day, quote your job all over the phone, and the job will be Dust-Free, all while keeping our prices below our competitors while maintaining the highest standard possible! It doesn’t get much better than that!

For jobs over the size of 10 square metres, we ALWAYS recommend leaving it up to the professionals.

Our affordable services will help you undertake your project while still staying within budget. Our clients save time by using our services to ensure they can get to the next part of their project on time without delays.

What Does Grit Mean For Wall Grinding?

One critical factor in achieving a successful Wall Grinding job is choosing the right diamond grit size. Diamond grit size refers to the size of the diamond particles embedded in the grinding tools. It plays a crucial role in determining the efficiency, speed, and quality of the grinding process.

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 Wall 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 Wall Grinding)

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

But they go all the way up to #3,000 grit – Which is for very fine polishing of 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 for faster prep work and removal of coatings.

(High Grit Number) – Are for smoothing, polishing, and final touch-ups.

How To Pick The Right Diamond For Your Concrete Grinder

Diamond tooling selection is crucial for making a profit and not going backward 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. The bond itself suspends the small ‘grits’ of polycrystalline diamonds 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. As the diamond is dragged across the surface of the floor, it is slowly blunted by the force of friction. At the same time, the 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 diamonds 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 Wall Grinding speed, it reduces the lifespan of the diamond disc or plugs. 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:

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

With HARD concrete – We use SOFT bond diamond discs or plugs.

Segments

Discs & plugs have a series of blocks called ‘segments’ attached to them by way of high-temperature solder. These segments are the components of the diamond disc and plug that does the Wall 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.
(EXAMPLE: 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.
(EXAMPLE: This red disc has VERY FEW segments, making it a very aggressive disc)

How To Grind Faster Using A Concrete Grinder

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

But they go all the way up to #3,000 grit – Which is for very fine polishing of 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.

– 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.

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 will wear 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 so 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.

MPA For Wall Grinding

What concrete hardness means for the Wall 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 says 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 it’s too slow or not cutting at all, change to a soft bond, but check the wear on the diamond after 10 minutes to make sure it’s not wearing too quickly.

A “Mohs Hardness Test Kit” can be used to also test the MPA of the concrete slab

The Mohs Hardness Test Kit is the perfect hardness tester for floors – to help choose the right diamond grinding tool for your job.

Mohs’ hardness is a measure of the relative hardness and resistance to scratching between minerals. Using the Mohs Hardness Tester Kit to determine the hardness or the scratchability of your concrete is useful for identifying the best diamonds to use on the job.

Once you have determined the hardness of the concrete you can make informed decisions about which diamonds to use without taking the risk they will wear out too fast or glaze over.

Taking the time to test your slab before grinding will allow you to get a longer grinding life out of your diamonds, saving you thousands of dollars in lost diamonds or unproductive work.

What Are The Power Requirements 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, it’s important to remember that your cable should be 30 metres long MAX. Otherwise, it will trip out your power constantly and won’t power the concrete grinder correctly. When using a powerful Concrete Grinder, mostly on larger jobs, you will need 15 AMP or Three-Phase power on-site.

When using Concrete Grinders in situations where there is no power on-site, it’s best to hire a 16 – 45 KVA generator as well as a heavy-duty 10 AMP or Three-Phase Power 30 Metre long cable 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)

DIY Guide On How To Grind Concrete

Managing the DIY Wall Grinding process yourself can save you money and give you the satisfaction of completing a DIY project – but it does come with challenges.

However, with a little bit of research and preparation, anyone can achieve a professional-looking finish. By choosing the right equipment, following proper techniques, and taking safety precautions, you can complete your DIY Wall Grinding project and enjoy a beautiful new surface.

To make your job easier (and safer), we’ll guide you through the process of DIY Wall Grinding in Sydney and provide you with all the information you need to get started.

From choosing the right abrasive to protecting your investment, we will cover everything you need to know to achieve a stunning new look for your concrete floors. Let’s break down the steps now.

Step 1: Gather your tools and materials

Wondering how to grind concrete? Before you start grinding, you’ll need to gather some tools and materials.

This includes:

– Concrete grinder & Diamonds
– Vacuum cleaner / Dust extractor
– Safety glasses
– Dust mask
– Hearing protection

You may also want to consider renting or buying diamond grinding cup wheels. You will need to purchase grinding discs and abrasive pads in various grits, depending on the level of grinding you want to do.

Step 2: Prepare the area

Before you start grinding, you need to prepare the area. This includes cleaning the surface and removing any furniture, rugs, or other items that may get in the way. You should also cover any electrical outlets or other sensitive areas with plastic sheets to protect them from dust and debris. It’s important to cover any smoke and fire alarms as well as air conditioners.

Step 3: Start grinding

Once you have prepared the area, it is time to start grinding.

Begin by attaching the grinding disc to the concrete grinder. Start at the farthest corner of the room and work your way towards the door. Make sure to use a light, back-and-forth motion and apply gentle pressure to avoid damaging the surface. Move slowly, and work in small sections, making sure to overlap each pass slightly to ensure an even grind.

Apply moderate pressure to the diamond pad and make sure to keep it moving across the surface of the concrete. You don’t want to focus on any one area for too long, as this can cause damage to the concrete. Concrete Grinders are also equipped with a dust collection system that will help avoid dust shrouding and keep the area clean while you Grind Concrete.

If you’re doing a full-depth grind, start with the coarse grit and move to a finer grit until you achieve the desired result.

For a full-depth grind, you’ll need to use a series of different grits to slowly grind down the concrete. Start with coarse grit and move to a finer one until you achieve the desired result. Grinding Concrete, for example, can be done using a series of 16, 24, 36, 60, and 80-grit diamonds.

Step 4: Change the grinding discs

Changing the diamond (disc, plug, or shoe) on a Concrete Grinder is very simple, although each of them attaches with a different method. You may need to change what diamond you are using, depending on what material you are removing and what finish you are looking for.

To get the proper polish, you must change the grinding discs as you grind. Working your way up to a finer grit, begin with a coarse grit. This will help you remove old coatings and rough spots and create a smooth surface.

For optimal DIY polishing results, you should change the grinding disc after every 2-3 passes and make sure to clean the surface between each disc change to prevent contamination.

Step 5: Vacuum the surface

Once you have finished grinding, you will need to vacuum the surface to remove any dust and debris. This is an important step, as any leftover dust can affect the final finish of your concrete. Use a powerful vacuum cleaner with a HEPA filter to ensure that all of the dust is removed.

Step 6: Seal the concrete

You should seal the concrete to protect it from moisture, stains, and other contaminants. You can use a concrete sealer, which will also enhance the colour and shine of the surface. Apply the sealer using a roller or brush, and make sure to follow the manufacturer’s instructions for drying time and the number of coats. You also have other options such as, but not limited to, Polished Concrete, Epoxy, Stencil Concrete, Spraycrete, Waterproof Membranes, Floor Levelling, Paint, ETC.

Step 7: Consider the environment

It’s important to keep in mind that grinding concrete can generate a significant amount of dust, which can be harmful to both the environment and your health.

To minimise the impact, you are using a dust extractor, which will help to reduce the amount of dust in the air. Silica dust is extremely dangerous and should be taken seriously. Click here to learn more about The Dangers Of Silica Dust From Wall Grinding

Step 8: Choose the right grinding equipment

When choosing a concrete grinder, it’s important to select the right equipment for the job. A smaller, hand-held grinder may be suitable for smaller jobs, while a larger floor grinder may be more appropriate for larger surfaces. Consider the size of the surface you will be grinding and the level of grinding you want to achieve when selecting your equipment.

Step 9: Follow safety guidelines

Wall Grinding can be dangerous if proper safety measures are not taken. Always wear safety glasses, dust masks, and hearing protection to protect yourself from dust and debris. Make sure to use a firm grip on the grinder and to keep the grinding disc level to prevent accidental cuts or abrasions.

Step 10: Practise Good Maintenance

To ensure that your concrete grinder continues to perform at its best, it’s important to practice good maintenance. Clean the grinder after each use, and follow the manufacturer’s recommendations for oiling and lubricating the machine.

Regular maintenance will help to prolong the life of the grinder and ensure that it continues to perform effectively.

Step 11: Create a unique surface finish

Wall Grinding is a great way to create a unique surface finish on your concrete floors. By using different grinding discs and abrasive pads, you can achieve a range of textures, from smooth to rough. You can also experiment with different levels of exposed aggregate and a large range of different finishes.

Step 12: Consider professional assistance

While grinding can be a DIY project, it can also be a complex and time-consuming task. If you are unsure about your abilities or if you want a professional-looking finish, consider hiring a professional grinding contractor.

A professional contractor will have the experience and equipment to handle the job quickly and effectively and will also be able to provide guidance and advice on the best techniques and materials to use.

For jobs over the size of 10 square metres, we ALWAYS recommend leaving it up to the professionals.

A Few Key Things To Keep In Mind When Wall Grinding

– It’s essential to use the correct diamond cup wheel for the job.

– Different wheels are designed for different tasks, so choosing the right one is essential.

– A grinding wheel with a coarse grit is better for removing large amounts of material, while a polishing wheel with a fine grit is better for finishing the surface.

– It’s essential to take care when Grinding Concrete, as too much pressure can cause damage to the surface.

– To achieve the best results, it’s recommended that you start with a lower speed and work your way up, gradually increasing pressure until you reach the desired results.

– The lowest speed is used when removing material from an existing concrete slab, with a higher speed used to create the profile for applying coatings or toppings.

– Move the Concrete Grinder slowly from left to right while slowly moving forward to ensure you don’t put too much pressure in one area for too long.

This is the basic guide on How To Grind Concrete. We always suggest contacting our specialist team for your project.

Free Wall Grinding Tips

– Ensure you use the correct diamond tooling with the appropriate bond hardness for the floor you’re grinding.

– Add some sand onto the slab before grinding to combat any leftover sticky residue on the surface. The extra grit will help open the diamond segments on your grinder, acting as an additional abrasive.

– If you use a multi-directional concrete grinder, reverse the heads’ spinning direction from time to time to re-open your diamond tooling. This will prevent scratches and inconsistent wear patterns.

– Pre-soaking the concrete slab will help maintain a lower surface temperature of the concrete and machinery. This will keep the diamond tools working effectively, especially when it’s hot outside.

– To begin, leave your dust collector on a lower power setting so the dust can build up a little under the machine. This will allow some of the particles to help open your diamond tooling.

– Using other equipment along with your concrete grinder can be very useful in some tough grinding jobs.
