Grinding concrete floors has recently become a popular flooring idea due to its multiple advantages. Concrete floors can last for several years, and their renovation works are also easy to finish. You can polish your concrete floors beautifully and also add some sparkle by introducing the add ons into the concrete mixture. Concrete floors are known for their long life. In addition to these aforementioned advantages, Concrete floors are also pretty affordable. Therefore, it has drawn the interest of several people now, and it is natural that everybody is interested in the know-hows of safely grinding a concrete floor.

Make Necessary Repairs

The first thing that you have to do is make sure that you repair all cracks, holes and bumps in your floor. It is ideal that you tackle these problems before renting or buying any equipment and working on grinding your floor. Once you have finished the repairs, sweep the floor off any dust, rocks, or remnants like oil, grease spots, paints, and epoxies from the surface. Grinding does not remove heavy and deep oil stains. That is why, it is important to finish repairing and cleaning the floor first.

Choose between Wet and Dry

There are two choices of grinding available; Wet grinding and dry grinding. Most contractors avoid dry grinding because the dust that rises in air poses health risks to the workers. If you have made up your mind to go with dry grinding, know that the place will be full of dust and you need to be prepared for a swift vacuum clean of the area soon. Also, use an approved dust mask along with safety glasses and ear plugs to protect yourself from getting in contact with the concrete dust (Crystalline Silica), which is considered to be a human lung carcinogen.

However, if you choose wet grinding, you can start by wetting the surface of the concrete that you are about to grind. It is ideal to work in small sections and make sure to work your grinder all the way up against the walls of the floor concerned.

It Is Essential To Pick The Right Diamonds

Diamonds make or break the grinding. Diamonds are very important tools that help in finishing the grinding process properly. Depending upon the condition of the surface of your floor, you are required to choose a diamond tool along with the right bond hardness. The type of abrasive selected will help in determining the efficiency of the process.

You can remember the rule of thumb here.

  • If you need to work on Soft concrete, use Hard Bond Diamonds.
  • If you need to work on Medium Concrete, use Medium Bond Diamonds.
  • If you need to work on Hard Concrete, use soft Bond Diamonds.
  • If you need to work on Very Hard Concrete, use Extra Soft Bond Diamonds.

The rule of thumb simply translates to – if you are working on hard concrete, use soft bond diamonds and if you are working on soft concrete, use hard bond diamonds. In your first few grinding jobs, the selection of diamonds should be of top priority. Take time to understand the bonds and segment styles properly.. Learn to test the concrete hardness if you are capable of it.  

Also remember that, if you are trying to remove something off the concrete floor, be sure of what you are going to do next. For example, if you want to polish the floor after removing the pre-existing glue, you should make sure that the diamonds you use do not leave deep scratches on the floor that are beyond repair. Speaking with the diamond manufacturer/vendor beforehand can give you the much needed depth of knowledge.

Grinder does the Magic

Concrete floor grinders are the most important part of the grinding process. They come in different sizes, weights, features and specialisations of power, motor size and direction of rotation of abrasives. Depending on the need, you can choose one that best suits your requirement. For polishing requirements, grinders with over 800 grits will be suggested.

To reach into the nooks and corners of the rooms easily, you can buy or rent the small handheld grinders. It is perfect for taking down a few high spots or those spots in difficult-to-reach areas. Handheld grinders provide for easy and quick solutions for tiny bumps and irregularities on both horizontal and vertical concrete floor surfaces. They are also very useful in clearing the surface off the remnants of paint coatings and epoxies as well.

While you grind your floor, keep the head of the cutter moving, particularly with a big floor grinder. You have to pivot the machine on its wheels and move the head of the cutter in a curved motion. If the cutting surface is moving only on one edge, try to work the machine in smaller circles to level the surface.
