Mistakes To Avoid When Concrete Grinding


Concrete grinding is a great way to resurface and maintain concrete surfaces. However, there are correct and incorrect ways to go about this. First-time users often make mistakes when grinding concrete. This includes not understanding the equipment, using the wrong bond, and forgetting to vacuum debris, to name a few. Learn about these mistakes to avoid when concrete grinding so you get the job done right.

Not Knowing How To Use Equipment

Once you buy the appropriate machine for the job, read the manual thoroughly to ensure you understand the device. Some manufacturers, such as EDCO, have product manuals and video tutorials for users. Educate yourself on the machine so you know how to assemble it, turn it on, and use it.

Pro Tip

Before buying a machine, review the product description and spec sheet to understand the ideal uses for the tool. Different grinders have varying capabilities; you need the right one for your job.

Using the Wrong Bond

Inspecting the floor allows you to determine the type of concrete you have to work with or the hardness. You also need to buy the appropriate bond for the concrete. Concrete that’s 6,000-8,000 PSI needs an extra soft bond diamond. On the other hand, soft concrete of no more than 3,500 PSI requires hard bond diamonds. Using the wrong bond can damage your machine, and it may fail to cut concrete.

What Is Bond?

The bond is where the diamond chips needed for grinding concrete are “bonded” to metal or resin. This allows you to grind concrete. 

Neglecting To Inspect the Floor

Don’t begin cutting as soon as you get the concrete grinder and bond. Instead, experts advise inspecting the floor for bumps and holes. Fill any pits or depressions before you begin grinding to prevent damage to the machine. Additionally, note areas where the floor seems uneven, such as trip hazards, so you know what areas to focus more grinding on.

Moving Too Fast

Contrary to what you may think, pushing the machine to move quicker won’t speed up the process. By moving too quickly, you risk damaging the engine of the grinder and breaking the tool. It’s better to spend more time than money, especially because concrete grinders are expensive. Plus, by moving too quickly, you may become sloppy in your work. Bottom line: take your time and allow the machine to do its job.

Forgetting To Vacuum Debris

Grinding concrete creates a lot of dust that’s dangerous to your eyes and respiratory system. Wearing eye protection and a mask and attaching an industrial vacuum is essential and legally required. Inhaling concrete dust is hazardous due to silica, which can cause lung disease or cancer.
