Polished concrete is rapidly becoming one of the most widely used uncoated flooring systems. With appropriate equipment and experience, concrete applicators 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 polished 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 comprehensive overview of polished concrete floors, including benefits, design options, equipment requirements and maintenance needs.
We are experts in polished concrete industrial 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.
The same happens with concrete. It has been used for many years, mostly for structures, but also for floors, but there are some drawbacks that we will discuss later.
Polished concrete is obtained by a process of grinding and polishing the surface using abrasive pads, to achieve a smooth finish. The final step is to seal the floor with a concrete sealer, and here there are two main types:
- Superficial sealer
- Penetrative sealer
Take a look at our blog for more detail:
Both sealants have different characteristics, at BECOSAN® we use sealers that penetrate into the core of the concrete and seal the concrete pores, this is more effective than surface sealers which lose their effectiveness through surface abrasion.
In general, polished concrete delivers the following features:
- High gloss finish
- Dense and hard surface
- Resistant to machinery traffic
- Ease of maintenance
In this short video you can see the last step of the BECOSAN® treatment and you can see for yourself 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:
- Surface area of the floor in m²
- Condition of the floor
- Amount of equipment and machinery to be relocated
- 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:

WHERE CAN POLISHED CONCRETE BE USED?
Polished concrete is commonly found in the following locations:
- Large warehouses
- Industrial facilities
- Logistics centres
- Car parks
- 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.
They also tend to be less slippery than waxed parquet or polished marble. However, in public facilities with heavy pedestrian traffic, preventing 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 carpetsin 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. Before the concrete sets the floor is trowelled to give a smoother finish.
Polished concrete is a process applied to concrete that has already set and has cured for a period of at least 30 days.
Here are some examples with photos to illustrate the most common finishes.
Here you can see a concrete lane smoothed with manual equipment.
Usually used outdoors, on areas with inclinations to increase grip. Once the concrete has been vibrated and levelled, it is brushed smooth, and it is this brushing that leaves ridges in the surface to improve grip.
Once the concrete is poured, the floor is troweled to create a flat finish.
And this is what troweled concrete looks like. Many people mistake it for polished concrete since the same machines are used.
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 stages are and how they must be carried out.
On the following page we explain the BECOSAN® treatment in more detail.
COLOURS IN POLISHED CONCRETE
A concrete with colour, either the typical green or red that we see very often, or any other colour, is compatible with a polished finish. Keep in mind that it’s necessary to apply enough pigment particles during the trowelling phase to ensure that the floor keeps its colour when polishing the surface. When the concrete is polished, a thin layer of around 2 mm is removed. If the colour of the concrete is not deep enough, the surface may appear patchy.
