7 Concrete Grinding Fails You Should Avoid and Why

7 Concrete Grinding Fails You Should Avoid and Why

The internet has proven so much help when it comes to gathering information especially when you need them at an instant but that does not necessarily mean that everything you see, read and hear on the internet are accurate or sometimes even true. When dealing with concrete grinding and sealing, you should be aware on what is what. Concrete grinding requires precision and should be meticulously handled because if you skip or add one more step then everything will fall apart and you will not get the results you want. How can you distinguish between what to and not to do? Here are 7 concrete grinding fails you should avoid and why so keep reading!



Choosing diamond tooling according to quality and not price is a best practice recommendation. Price is important, but it should not be the most important criteria. Poor quality tools cause several problems such as poor performance and scratches, and they also wear out more quickly.

We may find ourselves in a budget so we tend to go for the cheapest options but if you are looking for the best results then you should spend on the right tools rather than spending it on cheap tools but in the long run spend more on repairs because you now are faced with a crappy result due to the tools you used. So think about long term effects of the materials and tools you use and set the right budget for it so that you won’t have to worry about unnecessary expenditures in the future.


Understanding what the actual grinding process requires and how to achieve your desired results will help you determine how to get the exact finish you desire. It will also inform the type of bond that the diamond will be using and will ensure you remove materials such as epoxy flooring from the surface first.

There are ways for you to study and follow instructions on how concrete grinding works but you need to make sure to check your sources first. Read reliable sources to make sure that you are getting the proper information. This is critical to any concrete grinding projects because if you follow the misguided instructions then you will find yourself on the wrong end of the project and will eventually waste money, energy and time.


This is a common mistake made by many first timers. You might find yourself under immense pressure and time constraints. The increased speed used to get the job done faster is an enormously risky one as the diamonds can overheat, preventing them from cutting effectively.

Again, if you are fed with the wrong information such as “increasing the speed of the grinder will shorten your project time” then you will be faced with problematic situations that the only solution is to start over or buy new materials and tools which is something no one can afford if we are on strict budget or time constraint. When buying tools like the grinder, it is best to read the manual, look for instructional videos or let someone who knows how to work it show you how it is supposed to be done.


A metal bond diamond will grind and polish almost anything from steel, brass, glass, etc. AS LONG AS, the material is not “above grade” (raised above the floor surface).

Make sure you inspect the floors for anything above grade and either cut off, hand grind to level, or smack with a hammer to knock below grade. Once you’ve eliminated the above grade issues, you can grind it along with the concrete resulting in an interesting detail that adds to the personality of the floor. If you DO NOT inspect the floor and deal with the parts above grade before you begin grinding, you will most likely knock your diamond segment off and can do a lot of damage to your machine.


There are regulations regarding cutting concrete because of the health concerns related to silica dust in the concrete grindings that can be released into the air during the grinding process and must be captured a couple of different ways, the first being a dust collection system (a vacuum) but, and this is critical, not just any vacuum but a HEPA FILTER system, these take 99.97 per cent of the friable material out of the air making it safe to work and protects you from a really big fine in most of the world! The second is water, you can grind wet and this keeps the silica-containing dust captured in the concrete slurry. It is important to note that that slurry must be disposed of correctly as it is considered hazardous waste in most countries.


This may not seem like something that is overly important but in reality it’s incredibly important. Everyone has his/her own vision of how they want the floor to look upon completion- sometimes it’s achievable but not always, so it is important to effectively manage your expectations. This is often what happens to new to the polishing and grinding projects find most difficult. It is so important to properly educate yourselves on what is a reasonable expectation for their floor, because every floor is different and has its own “personality” so to speak.


Once you understand how metal bond diamond tooling works, you can use the general rule of thumb when selecting the tooling for your job. The “rule of thumb” is:  soft concrete requires hard bond diamonds and hard concrete needs soft bond diamonds.
