Takeaways by Stone Galleria AI

Granite can lose its high-gloss finish over time, but it can be restored through polishing. The polishing process involves several steps, including grinding, honing, and applying polishing pads. For on-site polishing, proper tools and techniques are necessary to achieve a renewed appearance.

  • Granite polishing restores its shine and can be done both at the factory and on-site.
  • The factory process includes grinding, honing, and polishing with specialized machinery.
  • On-site polishing requires a grinder and diamond polishing pads, with careful technique for best results.

Understanding granite polishing is essential for maintaining its aesthetic appeal and longevity.

One of the most satisfying aspects of investing in granite is admiring its stunning high-gloss surface, which can rejuvenate the entire space. This polished appearance is achieved through a meticulous process before the stone is installed. 

How is Granite Polished? Techniques Used in Factories and On-Site Restoration

However, with time and usage (though many years can pass with proper care), the shine gradually diminishes, leaving the original finish worn, dulled, and scratched. Fortunately, this doesn’t have to be permanent! One of the advantages of choosing natural stones is their ability to restore their gloss through polishing. If you’re eager to learn, how granite is polished and how it can be revitalised, you’re in the right place.

Polishing granite is an effective method to restore its beauty, making it appear brand new once again.

How is Granite Polished at the Factory?

When granite is extracted from a quarry, its appearance is quite distinct from that of the stone commonly found in buildings. You won’t truly know what it will look like until it’s cut into slabs and polished.

When it comes to factory settings, granite polishing is usually done in several steps using specialised machinery and skilled technicians. Let me give you a quick rundown of how granite is polished at a factory:

Starting the process

We begin by using coarse diamond abrasives to rough grind the granite slab, eliminating any unevenness, scratches, or imperfections on its surface.

Refining the Surface

Once the initial grinding is complete, a series of finer diamond abrasives are employed to achieve a smoother surface and enhance the texture of the granite.

Honing

Honing is the process of using diamond abrasives with increasingly finer grit to create a smooth and matte finish on the granite surface. This step is important in getting the granite ready for the final polishing stage.

Finishing Touch

The last step of the process is to polish the granite until it achieves the desired level of shine. There are different ways to achieve a polished finish on granite surfaces. One option is to use polishing pads or compounds, along with water or lubricants, to enhance the shine and lustre.

I can sense your thoughts. It may not seem possible to recreate this process on-site, but it can be done. It’s not necessary to repeat it so much, as it will vary depending on the depth of the marks and scratches on your granite.

How is Granite Polished, which is already installed?

Before diving into the process of polishing your countertop, it’s essential to make a distinction. We’re not referring to the use of “non-abrasive polishing products” that simply add gloss to stone surfaces without actually removing any material. What we’re discussing is genuine polishing—the kind where a thin layer of the surface is gently removed to reveal a fresh, flawless appearance.

Hardware Requirements

You’ll need a grinder and a set of diamond polishing pads. With this combination, you can easily replicate the factory polishing process on a smaller scale.

Polishing pads come in various grits, usually ranging from 50 to 3000. A pad with a lower grit number is considered coarser. So, if your granite has some deeper scratches, it’s best to start with a lower grit to properly deal with them.

Important

Handling this tool can be risky, and achieving a polished surface that looks brand new requires expertise and practice. It’s a good idea to consider outsourcing to experienced professionals when it comes to gleaming granite.

How is Granite Polished on-site?

Begin by thoroughly cleaning your countertop with a granite cleaner to ensure a pristine surface.

To address scratches, attach the appropriate polishing pad to your grinder and set it to a low speed as recommended. Start from the outer edge of the granite and gradually work your way inward.

Avoid applying excessive pressure; allow the diamond pad to effectively do its job.

Remove any excess dirt and continue the process with finer diamond polishing pads until you reach the finest grit available.

Once you’ve finished polishing, it’s time to apply some polishing cream. Grab a clean, dry cloth or buffing pad and gently buff the granite surface. Simply buff in circular motions until you achieve the shine and lustre you’re looking for. If needed, you can repeat the process for any tough stains or to further enhance the shine.

You might want to think about applying a granite sealer to help protect the newly polished surface and make it last longer.
