Polished Concrete Flooring
The basic premise of polished concrete flooring consists of the following steps:
- Cutting the concrete with an aggressive diamond embedded pad until an even cut, called a “scratch pattern” is produced.
- Polishing the concrete, starting with the highest level grit and ending up with the smoother level.
- Densifying the concrete using sodium or lithium silicate to strengthen the concrete surface.
- Polishing continues until the desired level of shine is achieved.
Benefits of Polished Concrete Flooring
- Low maintenance
- Repair and reuse of old slabs
- Improved reflectivity
- Noise – Just as densifying concrete increases its light reflectivity, it may also slightly increase sound reflectivity. Though EBN has not seen data to this effect, a polished, densified concrete floor may be acoustically brighter than a standard concrete floor, and it would assuredly be louder than a floor covered in a softer material, such as linoleum, cork, or carpeting.
Thermal Conductivity of Polished Concrete
As with ceramic tile, terrazzo, and other concrete floors, polished concrete flooring is more thermally conductive than most other flooring options. If not insulated beneath, the concrete slab floor may provide a significant conductive pathway for heat loss from a building, and it will reduce the mean radiant temperature (MRT) of a space, making occupants feel colder at a given air temperature. While this can be beneficial in the cooling season or when a building is being cooled, allowing the air temperature set point to be kept slightly higher, it does the same in the heating season, which carries an energy penalty—making it necessary to keep the air temperature higher. Even if a concrete slab is insulated underneath (and at the same temperature as the air), it can feel cool to the touch, leading to occupant discomfort and requiring a higher thermostat set point.
Like other hard-surface flooring, polished concrete flooring causes fatigue for those who have to stand on it for long periods of time. Appropriate area carpets or mats should be used to avoid these problems.
Polished Concrete Flooring is Eco-Friendly
- Energy savings – The reflectivity of the floor reduces the need for lightbulbs.
- Reduction in waste during installation – No carpet and/or tile trimmings
- Reduction in V.O.C.’s during installation – No mastic or solvent vapors being emitted
- Reduction in waste – Long-life floors don’t need replacing
- Reduction in waste (again) – Polished concrete can be used by all tenants

POLISHED CONCRETE FLOORING IS ACID SENSITIVE
If someone spills muriatic acid on your polished concrete floor, it will dull the finish instantly. Although it can be easily repaired, polished concrete flooring should not be exposed to acids.
We do not recommend our polished concrete floors for Citrus Processing Plants, Wine Manufacturing Plants, Pickle Processing Plants, Acid Manufacturing Plants, Soft Drink Manufacturing or Outdoor Applications (rain is normally acidic at 5.4ph and over time, it will dull the finish).
