Polyurethane Vs Epoxy Comprehensive Guide In San Diego

It is impossible to overestimate the significance of flooring. The flooring may change the look of your house, increase or hinder its functionality, influence your home’s health, and alter its worth.

Concrete floors are the most prevalent form of industrial flooring, but they cannot withstand time and deterioration on their own. They are frequently coated with resins to make long-lasting floors that are chemically resistant, abrasion-resistant, and strong enough to withstand the abuse that floors are subjected to.

Epoxy coatings and polyurethane coatings are the two most prevalent types of coating system resins for a concrete floor.

Both of these materials have their unique strengths and qualities, and they are suitable for a variety of industries and applications. They do, however, share certain crucial characteristics: both Epoxy and Polyurethane floor coatings are long-lasting, hard-wearing, and waterproof, as well as protecting your concrete floor from a variety of damage and filth.

What Is Epoxy Resin?

Epoxy resin is a thermosetting polymer coating that may also be used to seal concrete. It comes in three main formulations: water-based, solvent-based, and solids-based. These compositions allow for thicknesses ranging from 3 mils to over ten miles for a single coating. They can also influence application ease, give unique bonding properties, and pose distinct VOC concerns.

The epoxy resin adheres to a well-prepared concrete floor incredibly effectively. It’s sometimes used to resurface old or worn concrete and repair concrete floor cracks, pitting, and other surface issues.

High solids to 100 percent solids epoxy formulas are the best. They’re a very hard, thick, and impact-resistant material. This self-leveling thickness helps to fill in microscopic hairline cracks and defects in the surface while also protecting it with a high build layer.

They’re also effective against hot tire pick-up and abrasion damage. Even if certain epoxy formulae contain U.V. inhibitors, when exposed to sunlight for any period of time, they will ultimately turn yellow or amber, as the industry describes it.

When choosing an epoxy concrete flooring coating, keep this in mind.

The Benefit Of Epoxy Coatings On Flooring

The epoxy floor forms a strong link with the concrete beneath it. This bond creates a smooth, long-lasting flooring option that is far more durable than bare concrete.

Heavy Traffic

Epoxy flooring is great for locations with a lot of foot activity. They can endure a wide range of traffic, including pedestrians, forklifts, and automobiles. Having a flooring surface where you don’t have to worry about your traffic damaging the floor gives you a lot of peace of mind.

With a high volume of usage, alternative flooring choices may show wear and tear or require frequent waxing or recoating. On the other hand, epoxy coatings can withstand a wide range of users while requiring little maintenance.

Heavy Loads

Epoxy flooring, as previously stated, can sustain high amounts of traffic as well as a great deal of weight. Epoxy flooring, which may be found in airport hangars, fire stations, and hospitals, can handle very heavy loads of machinery without denting or scratching.

Epoxy flooring typically has a flexural strength of above 10,000 psi. Additional topcoat urethane coatings that make the surface even tougher for settings that demand greater abrasion resistance are available if you feel you need an even stronger floor.

Heavy Impacts

Epoxy flooring can withstand high traffic and weight, and high impact. Epoxy flooring can withstand severe impact and is difficult to scratch, dent, or damage, whether your employees are dropping items or pulling equipment.

While the flooring should be treated with care to guarantee that it lasts for years, it can also withstand everything you bring. If you discover damage or scrape, it’s advisable to take care of it right away rather than waiting for it to worsen.

Harsh Environment

Epoxy flooring may be an excellent alternative for your warehouse or industrial facility, regardless of whether your company demands extreme cold or high heat. Some Epoxy coatings can withstand extreme conditions, including deep freezers, depending on the kind of Epoxy used and the application technique.

Urethane and various topcoats are also available, making Epoxy flooring ideal for your company. It’s critical to get long-lasting flooring for your business. Epoxy flooring is a durable option that can withstand high traffic, heavy gear, and a high-impact environment.

Epoxy floors are a fantastic alternative for many businesses and buildings due to their ability to be tough and durable in a range of environments.

What Is Polyurethane?

Polyurethane (also known as PUR or P.U.) is a polymer made up of organic units linked together by carbamate (urethane) linkages. The majority of polyurethanes are thermosetting polymers that do not melt when heated. However, there are also thermoplastic polyurethanes.

Polyurethane may shield a surface against corrosion and other forms of deterioration. It can be glossy or matte in appearance. This sort of flooring is resistant to fire. Scratch resistance is possible if an extra coating is placed on top.

They can profit a lot from polyurethane’s flexibility in locations where it is subjected to moist weather and significant temperature changes and assaults from chemicals and caustic components.

A polyurethane coating (also known as urethane floor coating) is a highly flexible, abrasion-resistant floor coating with a high sheen and extended life. These materials, developed by I.G. Farben in 1937, were used to make gum rubbers, stiff foam, and elastomers.

Polyurethane flooring may readily be altered to increase or decrease pot life, recoat time, and overall curing time. Contractors can complete P.U. flooring in a fraction of the time because of this versatility.

Polyurethane, like Epoxy, is a thermosetting polymer that is used to create high-performance coatings. Although it is usually referred to as urethane, this is technically inaccurate, as there is a significant distinction between polyurethane and urethane.

It is polyurethane, not urethane, that is sold as a urethane coating. Aliphatic polyurethane is the preferred formulation for garage floors among the several formulations available. A polyurethane coating is just around 2 to 3 mils thick and cannot be changed like Epoxy while being roughly 60% to 70% solids depending on the manufacturer.

Polyurethane also has the benefit of being U.V. stable. This implies that even if it is exposed to modest amounts of sunlight over time, it will not become yellow. Polyurethane’s surface is not as strong as Epoxy, but it is far more scratch-resistant, can withstand wider temperature changes, and comes in a variety of finishes ranging from satin to highly glossy.

Because polyurethane does not adhere well to concrete and has a low dry film thickness, it cannot be used as a self-leveling coating to fill in minor cracks and divots. Another factor to consider is that most polyurethanes are solvent-based, which means they can emit a lot of VOCs and necessitate the use of a respirator.

The Benefit Of Polyurethane Coatings On Flooring

Polyurethane is a lot softer and stretchy. Therefore it’s perfect for places with a lot of foot traffic, parking lots, and food processors. This is due to its advantageous qualities, which include:

U.V. Stability

U.V. Stability is a term used to describe the capacity of a product to withstand

Polyurethane, unlike Epoxy, is U.V. stable (aliphatic polyurethanes), meaning it will not become yellow when exposed to sunshine.


Polyurethane resin flooring systems are normally more flexible, allowing for small movement, whereas epoxy flooring systems are more brittle.


Polyurethane, like Epoxy, is durable and long-lasting, making it ideal for areas with heavy weights and high traffic.

Minimal Maintenance

A polyurethane flooring system requires little to no maintenance, which is advantageous in busy 24-hour enterprises that require little to no downtime.

Heat Tolerant

Polyurethanes are excellent at withstanding heat, cold, and thermal stress.


  • U.V. Stability
  • Chemical-Resistance
  • Increased Impact and Abrasion Resistance
  • Finishes


  • Bonding to Concrete
  • Build/Thickness
  • Installation & Performance

Comparison Between Epoxy Vs Polyurethane Coatings

Epoxy and polyurethane resin systems are commonly utilized in busy food facilities where the floors are subjected to physical impacts, point loading, and traffic from equipment such as highly laden pallet trolleys and forklift trucks. Of course, all of these elements may harm a floor surface, and if the coating is sprayed too thinly, difficult-to-clean fractures can emerge, increasing the danger of undesirable microorganisms.

Businesses, manufacturers, and architects are constantly on the search for protected floor systems, frequently seeking realistic comparisons on Epoxy vs. polyurethane to avoid these hazards. Despite the fact that they are sometimes referred to as the same thing, they are actually two separate types of floor coverings with unique qualities. Here’s a comparison of the two systems to be sure you’re picking the appropriate one for you.


While a polyurethane system is more expensive than Epoxy at first, it is significantly more cost-effective in the long run. In reality, the P.U. system has a lifespan of about double that of the Epoxy, lasting 10 years vs. five for the Epoxy.

The improved wear, abrasion, and impact resistance qualities of P.U. systems are also advantageous.


Epoxy resins have a low resistance to organic acids prevalent in a wide range of foods and beverages, but polyurethane systems have unrivaled resistance to corrosion, inorganic, alkalis, organic alkalis, and solvents.

Heat Tolerance

Polyurethanes are excellent at withstanding heat, cold, and thermal stress. On the other hand, epoxies are stiffer by nature and can move with a concrete base when subjected to temperature changes. A normal two-pack, 100 percent solids epoxy coating has a heat resistance of up to 65 degrees Celsius, although certain P.U. systems can withstand 120 degrees Celsius.

This thermal shock tolerance is particularly useful in food and beverage operations, where daily temperature variations are common. For instance, when a room is steam cleaned, in locations where hot oven doors are being opened; or in regions where boiling liquids may spill onto the floor.


For the applicator, there are also substantial variances. Polyurethane floor resins are very sensitive to the presence of humidity from the standpoint of an applicator.

Although epoxy resins are susceptible to moisture, the damage caused by humidity will be far less severe. As a result, while operating in an area where humidity may be a problem, Epoxy is always the best option.

Polyurethane flooring may readily be altered to increase or decrease pot life, recoat time, and overall cure time. Contractors can complete P.U. flooring in a fraction of the time because of this versatility. With PU, a multicoat job might be started on Friday and completed on Monday. Epoxy floors are less forgiving in this regard, as they typically take seven days to fully cure.

Polyurethanes, in general, are more difficult to deal with. Because of their short pot life and sensitivity to humidity, they demand highly trained and experienced personnel.


It is clear from the previous information and comparisons of polyurethane and Epoxy that each has advantages and disadvantages for certain applications. Which type of coating should you use: Epoxy or polyurethane? You wouldn’t pick one over the other when it came to these two sorts of coatings.

Polyurethane is a superior alternative for industrial food processing enterprises that deal in milk, dairy, and cheese manufacturing since it can protect their flooring from organic acids, unlike Epoxy, which is prone to corrosion and yellowing in these situations. Polyurethane flooring is softer and more elastic than epoxy floors, making them more scratch resistant – excellent for high-traffic areas like multi-deck parking garages.

Epoxy is best utilized as a repair, patch, and build coat to conceal concrete flaws. After that, sand the Epoxy and apply a coat of polyurethane coating as a protective wear surface over the epoxy coating.

You can maximize the performance of your industrial and commercial flooring by combining Epoxy and polyurethane. Not only will you save money, time, and effort, but you’ll also be more productive.

To get the desired effect, you’ll need to blend both finishes. Combining these two types of floor finishes will result in a strong bind to the surface via Epoxy and a polyurethane topcoat, resulting in a safe, physically strong, chemically resistant, and aesthetically pleasing top layer.

Overall, the benefits of a polyurethane system surpass those of an epoxy coating applied with a roller.

One of the nicest things you can do for your industrial flooring and facilities is to use polyurethane on Epoxy. We may sum up by noting that Epoxy is the preferred substrate for general floor coatings, particularly on concrete floors. It fills in defects and gaps in the surface and adds thickness to the floor or tabletop.

In terms of mechanical resistance, chemical resistance, shock resistance, and U.V. protection, polyurethane, on the other hand, gives durability to the coating.

Use both of these coatings as a tough finishing option to produce exceptional results in terms of long-lasting, smart-looking floors, countertops, and tabletops.
