The Complete Guide to Polishing Concrete Floors: Process, Benefits, and Expert Advice

Polished concrete floors are a smart, modern choice for commercial, industrial, retail, and even residential settings. Durable, low-maintenance, and highly customizable, this flooring option has surged in popularity due to its clean look and cost-efficiency. Learn more about why polished concrete floors are so popular.

In this guide, we’ll walk you through how polished concrete floors are made, why they're such a great choice, and what you need to know if you're considering them for your space.

What Is a Polished Concrete Floor?

Polished concrete is created by grinding down a concrete surface with diamond abrasives, then refining it with finer grits to achieve a smooth, glossy finish. The process also includes applying a densifier to harden the surface and a sealer to protect against stains, moisture, and wear.

The result is a sleek, high-performance floor that can mimic the look of marble, granite, or tile - without the maintenance headache. You can explore more on our concrete flooring specialists page.

How Are Polished Concrete Floors Made?

The process is labour intensive and requires the right tools and expertise. Here's how our experts do it:

1. Surface Cleaning and Preparation

The first step is thoroughly cleaning the floor and removing any stains. Stubborn marks may require high-strength cleaning agents, used in well-ventilated areas with protective gear.

After cleaning, we patch any cracks using concrete filler and remove any protruding elements like nails or metal remnants. Learn more about our concrete repair services.

2. Testing the Hardness of the Concrete

We use MOHS hardness picks to assess the surface. This step determines which grinding discs are appropriate to use, ensuring the best results.

3. Grinding the Surface

We use industrial grade concrete grinders fitted with diamond-embedded discs. The process begins with coarse grinding to remove imperfections, followed by progressively finer grits for a smooth finish. A spray on densifier is applied mid process to reduce porosity and increase durability. For more information, visit our concrete grinding page.

4. Polishing and Sealing

Once the floor is ground and densified, we switch to polishing pads to achieve the desired finish, from matte to high gloss. Finally, we apply a water or solvent-based sealer to protect against dirt, grease, and moisture, while enhancing the floor’s reflectivity. View our range of floor sealing solutions.

Benefits of Polished Concrete Flooring

  • Durability: Handles high traffic, machinery, and wear with ease. Ideal for warehouses, factories, and showrooms.
  • Low Maintenance: No waxing, minimal sealing, and easy cleaning. Resists dust and allergens.
  • Cost-Effective: Long-term savings thanks to its durability and low upkeep.
  • Customisable Aesthetics: Stainable in a variety of colours and finishes. Exposed aggregate offers a terrazzo-style effect.
  • Environmentally Friendly: No need for additional materials. Makes use of the existing slab.

Applications: Commercial, Industrial & Residential

Commercial & Retail

Polished concrete floors are ideal for shopping centres, hotels, offices, and airports. Their light-reflective properties improve brightness and reduce energy costs while maintaining a clean, professional appearance.

Residential

In homes, polished concrete is increasingly used in kitchens, living areas, and basements. It’s durable, allergy-friendly, and works well with underfloor heating.

How Long Do Polished Concrete Floors Last?

With proper care, a polished concrete floor can last over 20 years. Regular cleaning, avoiding harsh chemicals, and periodic re-polishing will keep the surface in great condition for decades.

Can You Stain Polished Concrete?

Yes. Acid-based or water-based stains can be applied to achieve a wide range of colours and effects, giving you more design flexibility to match your aesthetic preferences.

Upgrade Your Space with Polished Concrete
