Polished concrete is becoming rapidly one of the most widely used uncoated flooring systems. With appropriate equipment and experience, concrete applicators and companies are able to polish surfaces, whether new or old and worn, to a high gloss finish that does not require waxes or surface coatings.
Given the high durability and performance of concrete, it’s not surprising that more and more facilities such as commercial warehouses, logistic centres, shopping centres and even homeowners are using it for their flooring.
This section provides a very comprehensive overview of polished concrete floors, including benefits, design options, equipment requirements and maintenance needs.
We are experts in polished concrete industrial floors.
Dust-proof, durable, resistant and easy to maintain polished concrete floors.
What is polished concrete?
Compare a polished concrete floor to a wooden panel. It’s use can be practical, but if you look for a finer finish, you have to grind and varnish that wood, correct?
The same happens with concrete. It has been used for many years, mostly for structures, but also for floors, and it carries some inconveniences that we will talk about later.
Polished concrete is obtained by a process of grinding and polishing the surface, to achieve a smooth texture, and far less rough. The final step is to seal the floor with a concrete sealer, and here there are two main types:
- Sellador superficial (equivalente a un barniz).
- Sellador penetrante.

Both sealers have different characteristics, at BECOSAN® we use sealers that penetrate into the core of the concrete and seal the concrete pores, preventing wear of the same sealer on the surface, which loses its effectiveness with surface abrasion.
In general, when we talk about polished concrete the following characteristics arise:
- High gloss
- Dense and hard surface
- Resistant to machinery traffic
- Floor very easy to maintain
In this short video you can see the last step of the BECOSAN® treatment and appreciate the high gloss finish of the floor.
Polished concrete price m2
Let’s talk about how much polished concrete costs. The price of polished concrete varies according to the following aspects:
- Square meters of the application
- Initial floor condition
- Displacement of working equipment
- Type of finish (matt, semi-gloss or high gloss)
- Execution time
The breakdown of prices for a polished concrete exterior or interior could be as follows:
- Materials required
- Polyethylene layer, insulation, coating, etc.
- Concrete, the price depends on several factors: color, type of aggregate, steel fibers, etc..
- Steel mesh
- Machinery Equipment
- Vibrating ruler
- Laser leveler
- Concrete power trowel
- Concrete grinder

Where can polished concrete be used?
The most common areas where polished concrete is used are:
- Large warehouses
- Industrial facilities
- Logistics centres
- Shopping centres
- Retail stores
- Hotels and restaurants
- Office buildings
Polished concrete floors
Polished concrete is often confused with troweled concrete, and although both have similarities, they have very different finishes.
Exterior polished concrete
Here we can see the same polished concrete floor from different angles. It is an exterior concrete floor.
Interior polished concrete
The common practice is to use this finish for interiors with large surfaces. Here you can see some polished concrete floors in industrial buildings.
Do polished concrete floors slip?
Polished concrete floors may look as smooth as glass, but they are completely safe to walk on when kept clean and dry, like any other surface.
They also tend to be less slippery than waxed parquet or polished marble. However, in public facilities with heavy pedestrian traffic, preventing slip and fall accidents is an absolute priority.
- Keep polished floors free of oil, grease and water. Follow a routine maintenance schedule and clean up spills and stains as soon as possible.
- Placement of rubber carpets in high traffic entrances.
Differences between polished concrete and troweled concrete
As an example, we have an industrial facility where we want to install a troweled concrete floor. This is when the surface is prepared, the mesh is laid and the concrete is poured, which is then troweled.
From this point on we have to think about the finish that the floor will have. Find some examples with photos to illustrate the most common finishes.
Here you can see a concrete lane smoothed with manual equipment.
Usually used outdoors, or areas with inclinations to increase grip. Once the concrete has been vibrated and leveled, it is brushed to smooth and flatten it, and this brushing leaves tufts in the ground.
Once the concrete is poured, the floor is troweled to create a flat finish.
And this is how troweled concrete looks like. Many people misunderstand it as polished concrete since the same machines are used.
Troweling concrete is the last step in the process of installing a concrete floor and from here we can start with the polishing process: BECOSAN® treatment
Polished concrete, how is it made?
Whether for indoor or outdoor use, the steps to follow to polish the concrete are the same.
Basic requirements for polishing concrete
- The surface to be treated must be smooth, therefore it is recommended to start from a troweled floor.
- It must be properly cured and hardened.
- Free of resins and paints.
- Free of screws, holes and imperfections.
Not all conditions can always be satisfied, which is why floor preparation must be carried out in advance. In other posts we will explain what these preparations are and how they are carried out.
On the following page we explain the BECOSAN® treatment in more detail.
Some case studies
Colours in polished concrete
A concrete with color, either the typical green or red that we usually know, or any other color, are compatible with a polish. Keep in mind that it’s necessary to apply enough pigment particles in order that the floors remains colored when polishing the surface.
When the concrete is polished, a thin layer of less than 2 mm is removed. If the colour of the pavement is not deep enough, areas with patches may arise.
