How to Polish Concrete Floors with MasterCut Diamond Grinding Tools

1. Identify the condition of the concrete floor

If you plan to polish an existing concrete floor you must first evaluate the condition of the surface. You will need to determine the hardness of the concrete with a MOHS Concrete Hardness Tester.

2. Prepare the surface

Remove any existing sealers and coatings by using coarse diamond grinding shoes, diamond grinding cup wheels or PCD grinding tools. Repair/fill any surface cracks.  If the concrete floor has only minor blemishes or a very light coating, you can move on to the initial floor grinding process.

3. Begin Polishing

Now you’re ready for the initial rough grinding with metal bond diamond abrasives that prepare the concrete for final smoothing. This concrete grinding procedure is generally a one to two step process, depending on the condition of the concrete. In this step, you can use diamond grinding shoe, diamond grinding plate, diamond grinding cup wheels and other diamond grinding disc, which is according the floor grinder machine that you use.

4.Densify the Concrete Floor Surface

After performing the initial grinding, it is beneficial to apply a liquid chemical hardener to the concrete to help solidify and densify the surface and to provide extra protection from water penetration and staining. Hard concrete floor also produces a better polish. 

5. Final Polishing

With each successive pass, the goal is to buff out the scratch pattern from the previous pass (lapping). As you gain more experience, you will know when to switch to the next-finer grit level by observing the floor surface and the amount of material being removed.

6. Protect Polished Concrete

Once you get the look and polish you are striving for, you may want to protect the concrete floor surface by applying a commercial stain-guard product, especially if the concrete surface will be exposed to grease, oil, or chemicals. Similar to Scotchgard for fabric, these solutions penetrate the surface to make the floor more resistant to stain absorption and dirt. They are usually applied by pump sprayer.
