What Is Concrete Polishing and Why Is It Important?

Do cracks, divots, and other imperfections make your concrete floor difficult to keep clean? Does it look dull and uninviting? If so, your surfaces may benefit from a process called concrete polishing. Keep reading to learn more about this process and how it can help you achieve the perfect floor.

What Is Concrete Polishing?

Concrete polishing involves grinding down a concrete surface to reveal a fresh, new layer. This technique can work for interior and exterior surfaces, from patios and driveways to basement floors. Professionals can hone and polish the material further to create a smooth, glossy finish. Let’s go over the step-by-step process of polishing concrete:

First Cut

Professionals begin by grinding down the surface using a metal-bond diamond concrete grinder with a 20/30 grit level. This step eliminates uneven spots and strips away old coatings and also “opens up” the pores of the concrete to allow for better penetration during the next steps.


If the first cut makes cracks, air pockets, holes, or other visible damage, the surface will need grouting. While the grout is still wet, professionals will go over it with a 100/120 grinder to fill in the pores. Then, they clean the whole surface until it’s free of any residue.

Applying Densifier

With the surface fully prepped, it’s time to apply the densifier. This resin soaks into the pores of the concrete and hardens it, making it less susceptible to staining and deterioration. Once the densifier dries, professionals use a higher-grit grinder to remove scratches and smoothen the surface further.


The fully resin-bonded floor is now ready for concrete polishing. Depending on your preferred sheen and texture, the polishing process can involve different grinders and abrasives. An 800-grit resin pad, for example, will create high-gloss concrete surfaces, and 400-grit makes a low-gloss finish.

Applying Sealant

To protect the surface, professionals apply a sealer after polishing. This clear coat helps the floor resist staining, fading, and other forms of damage. Depending on the product used, curing can take hours or days.

The Benefits of Concrete Polishing

Polished concrete flooring can make a drab space feel brand new. You can choose different sheens, colors, and finishes to create the perfect look for your business or home. Aside from visual appeal, it also offers many functional benefits:

Enhanced Durability

Polished concrete can withstand heavy foot traffic, equipment, and furniture without showing signs of wear and tear — which is why most factories, warehouses, and other commercial spaces opt for polished concrete flooring. It’s almost impossible to chip or scratch and won’t corrode when exposed to chemicals.

Low Maintenance

You won’t need to wax, seal, or power wash these floors. A simple mopping with a pH-neutral cleaner is all it takes to keep them looking new. The smooth, even surface also makes it easier to clean, so you can say goodbye to those pesky nooks and crannies.

Extra Illumination

The highly reflective surface of polished concrete also amplifies the light in a room, making it seem brighter and more spacious. It’s perfect for small spaces that need a little visual “pick-me-up.” It can also lower your energy consumption because you won’t need to rely as much on artificial lighting.

Lengthened Lifespan

Polished concrete surfaces last much longer than their bare counterparts. When properly installed and maintained, they can serve you for decades.

Improved Safety

Many assume that polished concrete feels slippery, but that’s not the case. Professionals can apply a slip-resistant coating during installation to reduce the risk of nasty falls.

Reduced Allergy and Asthma Symptoms

If you suffer from allergies or asthma, polished concrete might be the perfect flooring solution for you. Its non-porous surface doesn’t trap dust, pollen, and other allergens that can trigger an attack.


Instead of spending money on expensive flooring materials, you can simply refurbish your existing concrete surfaces. This project is very cost-effective in the long run, saving you from premature replacement.
