Epoxy vs PU flooring becomes quite necessary when deciding on floors for use in factories and workshops, among other commercial buildings. The two types of coatings are used to create a protective layer on the concrete floor and vary in flexibility, chemical resistance, heat resistance, and others. Choosing any of the two depends on the type of use the floor will get.
CoatEXX Industrial Solutions supplies flooring systems for industrial and commercial applications where special demands exist with respect to functionality of the floor. Which flooring system is needed can be determined by the presence of heavy vehicle traffic, load from the machinery, chemicals, cleaning, humidity and quality of existing concrete.
Some places may need Epoxy Floors because of its hardness while others need PU floors because of flexibility and resistance to heat. Either floor type is not suitable for all kinds of conditions; it pays well to make a comparison of their characteristics before installing them.
Epoxy Flooring can therefore be defined as a form of flooring created by combining epoxy resin with hardener. This combination is allowed to cure to produce a hard coating layer on the well-prepared concrete base. According to the floor, the epoxy flooring will consist of a flat coating that is resistant to chemicals and abrasions.
Industrial epoxy flooring is usually applied in factories, warehouses, assembly plants, laboratories, among other places.
There are different types of epoxy floors, ranging from thin film, epoxy self-leveling to epoxy screeds.
PU flooring or polyurethane flooring uses polyurethane resin systems for the provision of a protective layer on the floors. It is a flexible, wear-resistant, and chemical resistant flooring system, depending upon the resin systems used in its making.
PU floors are recommended for food processing plants, commercial kitchens, pharmaceutical zones, manufacturing areas, and any environment requiring certain floor properties.
There are some polyurethane flooring systems formulated for zones subject to changes in temperature; others are wear-resistant or formulated for chemical exposure. PU-cement floors are another system combining the polyurethane resin with a cementitious system and is used for very demanding industrial environments.
However, the difference between epoxy and PU flooring is mostly determined by their characteristics and applicability in various operating conditions.
The first difference is that epoxy flooring creates a hard and rigid surface. It can be used in many production plants, warehouses and workshops. It gives a protective coat on top of a well-prepared concrete and can withstand the necessary level of traffic and wear.
As for PU flooring, it is flexible to a certain degree. It can be useful when there are some requirements for flexibility because of changing temperatures or movements of the surface.
Both of the types of floors can resist some chemicals, but not all of them. Neither of them is universal in terms of chemical resistance.
It is necessary to choose one depending on the kind of the chemical, its concentration, temperature and contact time with the surface.
While conventional epoxy floors work well in stable indoor environments, some floor systems can be negatively affected by drastic temperature changes and thermal movement.
Some PU flooring systems can be capable of dealing with temperature variations better than others. PU cement flooring is suitable for particular zones subjected to exposure to hot water, steam cleaning and/or thermal shock, where the system should be qualified for that purpose.
The below table provides the differences that should be considered while choosing the industrial flooring systems.

These are general comparisons, not assurances for all products. Specifications for the proposed flooring should be the determining factor.
The selection of floors in an industrial building must depend on the kind of activity in every particular space. A factory will have different needs for its production floor, storage area, washing area, and equipment area.
Epoxy floors can prove appropriate for numerous manufacturing units and workshops when there is a need for durability and washability of the floor. They can be installed in assembly lines, equipment rooms, inspection areas, and selected production spaces.
PU floors can be taken into account where flexibility or particular properties of chemical and thermal resistance render them preferable.
Warehouses are sites that witness continuous movement of pallet trucks, forklifts and loaded goods. The use of epoxy and PU floors is dependent upon the amount of traffic and product selection.
The flooring company should evaluate wheel traffic, turning zones, load concentrations, and state of the concrete before carrying out flooring works. A decorative finish may not be enough for all heavy-duty applications.
Food processing plants will likely need floors that are easy to clean, hygienic, and resistant to certain cleaning agents. Certain PU cement floors can prove helpful where there are exposures to heat or hot water or stringent cleaning procedures.
The epoxy floor coating can also be used in some food-processing sections where the epoxy meets some of the hygiene requirements. This will be dependent on various issues such as temperature, drainage, slip resistance, and cleaning processes.
Certain chemicals and environments might call for floors that resist certain chemicals yet permit cleaning. The epoxy and PU coatings must be evaluated with respect to the type of chemicals in use, their exposure period, and the surface finish.
The specification of the project in certain cases will have to consider issues such as joint detailing and contamination.
Epoxy vs PU Flooring Cost : The cost of PU flooring should factor in the complete installation system as opposed to just the cost of materials. The total cost will be determined by the size of the floor, state of the floor, selection of materials, thickness of the coating, and installation requirements.
Some of the influencing factors for epoxy flooring cost include:
Costs of installing PU floors will vary depending on the type of polyurethane system involved as well as the level of performance expected.
Preparation of the surface, repairs, application, and curing time also form an important aspect of quoting.
In comparing prices, it is imperative that you compare quotations which have similar levels of preparation, priming, flooring thickness, finishes, and curing time. The lower quotation may not necessarily be the best choice when some aspects such as these are not included.
For factory floors, before considering epoxy or PU, first, identify the needs that the floor must satisfy.
Epoxy could be used where there is a need for a durable floor with industrial traffic and easy maintenance for resistance to specific conditions such as heat or chemicals.
Before selecting any of the above, one should consider these questions:
While the installation process will vary from one type of product to another, there are some steps that all industrial floors have to go through in order to install them.
The moisture content, environmental conditions, mixing ratio, and application time need to be taken care of as per the selected product.
CoatEXX Industrial Solutions offers industrial and commercial floorings for industrial and commercial premises where there is the need to put a protective coating above the concrete flooring.
The process of selection of which flooring system to install will be determined by knowing the working environment, the existing floor, and the kind of performance one needs from the finished floor.
When considering PU and epoxy flooring systems, the goal should be to pick the system rather than the materials to be used for all the works.

In general terms, epoxy floors tend to create hard surfaces, whereas polyurethane floors are more flexible. This is dependent on the formulation and operational conditions of the floor.
Not necessarily. While epoxy floors may be suitable for numerous warehouse and workshop applications, particular polyurethane floors may be more suitable under certain conditions.
This is again dependent on a number of factors, such as the type, thickness, preparation, and specifications of the floors. Comparing costs of two floors requires full quotations of installations.
Yes, epoxy flooring may be used for many factory floors depending on the type of flooring system that will be selected based on traffic, machinery loads, chemical exposure, and condition of the concrete floor.
There are certain types of PU-cement flooring systems which are specifically designed for use under severe wet-processing conditions and temperature changes. You need to ensure that the product description specifies its suitability for hot water and cleaning process.
None of these two products have better chemical resistance properties. You need to consider the type of chemical, concentration, temperature, and time of exposure to chemicals to make an appropriate selection.
You need to take into account the purpose of the floor, traffic, machinery loads, chemical exposure, temperature changes, cleaning procedure, and condition of the concrete floor.
