The Science Behind Concrete Polishing: How It’s Done

The gleaming floors at your favorite mall or the shiny surface of a new warehouse aren’t just there for show. This results from a process known as concrete polishing. This technique transforms rough and dull concrete surfaces into smooth, high-luster finishes. But how does it work?

In this post, we’ll break down the science of concrete polishing and the techniques professionals use to achieve these stunning results. So, if you’re interested in the technical aspects of polished concrete, keep reading!

1. Removal of Existing Coatings

The first stage in expert concrete polishing services involves removing any existing coatings on the surface. For this, professionals use coarse diamond segments bonded in a metallic matrix, capable of eliminating minor pits, blemishes, stains, or light coatings from the floor.

2. Sealing Cracks & Joints

Next, the contractor uses epoxy or another semi-rigid filler to seal any cracks and joints in the cement. This step ensures a smooth and even surface for the subsequent stages of the concrete polishing process.

3. Grinding with Metal-Bonded Diamonds

Now, the actual grinding begins, using metal-bonded diamonds of varying grits. Professionals start with a 30- or 40-grit diamond, move on to an 80-grit, then a 150-grit metal-bonded diamond or finer, if desired. This systematic progression helps achieve a uniformly smooth surface.

4. Application of Chemical Hardener

After grinding, concrete polishing contractors apply a chemical hardener to densify the surface. This sealer sinks into the floor, protecting it from the inside, hardening, and densifying the material. Not only does this step provide protection, but it also enhances the longevity of the polished surface.

5. Polishing with Resin-Bond Diamonds

The following stages involve fine grinding using diamond abrasives embedded in a plastic or resin matrix. Concrete polishing contractors begin with a 100- or 200-grit resin-bond diamond or a combination of these. They move onto a 400-grit, then an 800-grit, and finish with a 1500- or 3000-grit resin-bond diamond, depending on the desired sheen level.

6. Optional Stain Guard Application

To further protect the polished surface and make it easier to maintain, professionals apply a stain guard. This also helps keep any residue remaining on the floor from the polishing process and leaves a dirt-resistant finish.
