How to Polish Limestone

Limestone is a sedimentary rock made from calcium carbonate. Impurities often interfere with its formation process, resulting in a wide range of color and variation options. Because of its durability, heat resistance, and versatility, limestone is a popular choice for flooring, countertops, and fireplaces. Unlike marble, limestone isn’t generally known for its high shine. However, you can achieve a polished look on limestone quite easily. Polishing will brighten the appearance of the limestone and enhance its natural color and variations. Follow this guide to get the polished shine you desire.

Prep The Surface

Before you begin, you’ll need to thoroughly clean your limestone. If it’s a floor you’re working with, sweep up dirt with a soft-bristle broom or use a gentle vacuum. Lightly mop the surface with a damp mop, paying attention to any areas that may have caked-on dirt. For other surfaces, like countertops and walls, you can use a pH-neutral stone cleaner and a non-abrasive sponge.

Polish Limestone with Mineral Oil

The simplest way to polish your limestone is with mineral oil. Avoid using polishes that contain wax as this will yellow the limestone and trap dirt. Apply the mineral oil to a soft, clean cloth and wipe on the surface using a circular motion. This process is the quickest, easiest, and cheapest way to achieve a polished finish on your limestone.

Polish Limestone with a Hand Polisher

Another tool you can use is a hand polisher. Unlike with mineral oil, this method doesn’t just create the look of polish — it actually gives the limestone a true polished surface. Start on a low-speed with a 3000-grit diamond pad. Use a spray bottle to keep the surface slightly wet. Rotate in a counterclockwise oval pattern for about 20 seconds. Repeat if necessary.

Once you’ve covered the entire area, rinse the surface with a soft sponge. Then install an 11000-grit diamond pad to the polisher and repeat the same process. Rinse again and let it air dry. It’s more time-consuming than mineral oil, but you’ll achieve a longer-lasting result.

Hire a Professional

If DIYing isn’t your thing, you can hire a professional. Resurfacing limestone floors can be an especially daunting task. A professional floor refinisher will be able to accomplish the best result with the use of industrial equipment and professional-grade powders. Though this is the most expensive option, you are likely to be most pleased with the high-end shine a professional stone polish can give you.
