The Importance of Diamond Grinding & Polishing

Diamond grinding and polishing are terms used to describe certain processes involved in prepping, transforming, and polishing concrete surfaces. Concrete grinding and polishing uses metal or resin-bonded diamond discs, much like a craftsman uses sandpaper on wood, to prepare concrete for epoxy coatings, stains, dyes, or polishing (when either desired or necessary). Each level of diamond discs has its purpose from the more aggressive grinding to the finer polishing.

Depending on the application, the diamond grinding process helps to address almost all of the surface issues that your concrete could have. Aggregate exposure is also generated during this process, whether aesthetically intentional or as a byproduct of necessary grinding. Our team makes sure that you know of all the factors and present limitations in your concrete as we work so you always have realistic expectations and know that you made the right flooring choice.

Diamond polishing is the term used when resin bonded diamond discs hit the floor. Each step is a continual progression of polishing the floor to the desired finish. There are three basic finishes for polished concrete surfaces:

· Low-Satin Finish (400 – 600 Grit)

· Medium-Gloss Finish (800 Grit)

· High-Gloss Finish (1500 – 3000 Grit)

A densifier is also applied during the polished process, which hardens and strengthens the floor. It acts as a preventable barrier against moisture and dust due to the nature of concrete and its porosity.

Finally, a guard or penetrating protective coat can be applied after all of the polishing is complete. The product is burnished into the floor and helps protect and guard the finished or polished surface. Guard products designed for polished concrete are very beneficial for increasing reflectivity and resistance to staining, however they do leave the floor susceptible to mild scuffing.
