Guide to Concrete Polishing

Concrete polishing is an excellent way to increase longevity, compressive strength, and corrosion resistance. It enables the surface to repel surface contaminants, such as oil, chemical, or moisture, without you having to invest in additional special protection materials.

While concrete polishing is a significant investment, you must know its preparation techniques, types that include matte finish or high-gloss, and their benefits. This will help you make informed decisions and get the floor according to your personal preferences.

Continue reading to find detailed information regarding the steps involved in concrete polishing, and its benefits.

Concrete Polishing Process

Concrete Polishing Process

Concrete polishing is done in two ways, i.e., dry method or wet polishing methods, each of which has its pros and cons. The dry method is more common than the wet method as it is comparatively more convenient, quicker, and environmentally friendly. On the other hand, wet polishing method is more labor-intensive and creates slurry material that needs to be appropriately disposed of to prevent environmental hazards.

The steps involved in concrete polishing are:

1. Assembling the Tools

You need to consider factors, such as the working surface type, to choose the right set of tools. For instance, if you are working on hard concrete surfaces, you will require soft diamond-bonded abrasives to smoothen the surface. Additionally, if the surface is soft, very hard diamond abrasives need to be used for floor smoothening. Besides, you need tools like polishers, grinders, industrial vacuums, stains, and densifiers to produce a smooth finish on flat surfaces.

2. Sealing and Filling

You must clean the surface and look for gaps and holes. See if there are any expansion joints in the concrete that need to be filled. You can use urethane caulk as a concrete expansion joint sealant to fill the cracks or fill them with acrylic-based grout.

3. Applying Densifier

After that, apply the concrete densifier evenly across the surface to further tighten pores and irregularities in the concrete.

4. Polishing the Surface

After applying the densifier, you can polish the surface to further enhance the floor’s aesthetics by using burnishing machines to create a shine. You can begin the process with 400-grit resin abrasives for a lower gloss and an 800-grit resin pad for a higher-gloss finish.

5. Applying Sealer

Then, apply the polishing guard so it soaks into the floor and maximizes its sustainability. In contrast, if you apply topical sealer, know that it will eventually need to be reapplied as it sits on the surface instead of soaking in.

Benefits of Polished Concrete Floors

Concrete polishing helps ease the maintenance process while making the surface immune to molds and water damage. Other benefits are discussed below:

1. Affordable

Polished concrete floors are comparatively more economical than other flooring options. On average, the rates range between $3 to $12 per square foot. Also, they have low lifecycle costs, meaning they are likely to last longer and do not need to be replaced as often as other floors.

2. Durable

A polished surface is an excellent passive and corrosion-resistant option that can withstand heavy foot traffic and equipment. This is because polishing creates a thin oxide layer that further provides a barrier to corrosion and helps achieve a more aesthetically stable surface.

3. Environmentally Friendly

Polished surfaces are energy efficient because they allow light from outside to reflect and brighten up the space, decreasing the use of unnecessary lights. This lowers the need to burn fossil fuel to generate electricity that powers lights.

4. Low Maintenance

Polished surfaces are excellent work surfaces that are less susceptible to stains or permanent damage. This is because the polished stone acts as a protectant that closes stone pores and prevents stains from spreading.


Polished surfaces are highly popular for their smoothness, denture retention, stability, and aesthetics. Additionally, the polishing not only enhances the appearance of the surface but also prevents unnecessary contamination, and stains, that may otherwise demand consistent maintenance.
