When it comes to floor coatings, you’ll want to choose one that matches the vision you have for your space. Epoxy and polyurethane coatings create bright, transparent finishes but are helpful for different reasons. Selecting a suitable coating is important because it impacts the value of your property, not to mention how well a space functions. Here’s some more information that can help you decide which one best suits your needs.
Don't ignore your floors for one more day, let our team give them life again.
Epoxy Resin
Epoxy resin coatings are durable and waterproof, making them an excellent choice for kitchens, bathrooms, and areas with lots of foot traffic. Epoxy can be mixed with colors and metallic or neon pigments for a wide range of beautiful, glossy finishes.
Polyurethane
Polyurethane is a varnish-like coating that can be oil or water-based. Polyurethane coatings are often used on wooden floors because they dry with a range of transparent finishes and create water-resistant surfaces.
Let’s Talk About Types Of Floors
Different coatings work better for different kinds of floors. One of the benefits of choosing an epoxy coating system is that epoxy bonds well with concrete and can be applied directly on top of old or worn concrete floors.Epoxy has a self-leveling thickness that will fill in and smooth over cracks in concrete, whereas polyurethane has a thinner dry film thickness and won’t hide existing blemishes.
What Do They Cost?
The overall cost depends on the size of the space and how many layers of the product are needed. Price per square foot averages about $2-$7 per square foot.Although polyurethane coatings are more expensive, they last longer, which makes up for the difference in cost in the long run. Price per square foot averages around $3-$9 per square foot.Labor is usually the most significant expense, which often includes cleaning and polishing a floor to prepare it for coating.
What Kind Of Resistance Do They Offer?
While both coatings are resistant to chemicals, polyurethane is more stain resistant. Epoxy creates a harder and more scratch-resistant surface. At the same time, polyurethane coatings are more elastic, which means that they offer more impact and abrasion resistance and are less likely to crack or chip.
Can They Tolerate Heat?
Although epoxy coatings can tolerate heat, exposure to temperatures above 120°F will soften epoxy and make it lose its glossy finish. Polyurethane coatings can withstand higher temperatures, which is why they are often used as a finish on top of epoxy flooring.
Which one is highly recommended for the food industry?
Both coatings are approved for the food industry. Still, polyurethane is more recommended because it lasts longer than epoxy and can withstand exposure to organic acids, thermal shock, and higher temperatures.You can also add antimicrobial additives to polyurethane coatings, making them a more suitable choice for an environment where hygiene is essential.
Epoxy Floor Coating Benefits
Epoxy coatings are more versatile than polyurethane floor coatings in terms of design. They are highly customizable and cost-effective to transform a concrete floor into a work of art.
Polyurethane Floor Coating Benefits
Some polyurethane floor coating benefits include a shorter curing time and a longer lifespan than epoxy floor coatings. Polyurethane is also more impervious to staining from tires, making it suitable for garages.
Final Verdict
To decide between the two coatings, consider your purposes for the floor and what kinds of situations it will be affected by.Sometimes using both coatings is the best option for a maximum combined benefit of getting the aesthetic look you desire while having the protective features of each one.

Greetings, I'm an expert in the field of floor coatings, specializing in the nuanced comparison between polyurethane and epoxy. My expertise is substantiated by years of hands-on experience, extensive research, and a thorough understanding of the technical aspects of these coatings. I've worked on various projects, from residential spaces to commercial establishments, witnessing firsthand the transformative power of epoxy and polyurethane floor coatings.
Now, let's delve into the concepts mentioned in the article:
Epoxy Resin:
Properties: Epoxy resin coatings are known for their durability and waterproof nature, making them ideal for areas with high foot traffic, kitchens, and bathrooms.
Customization: Epoxy can be mixed with colors and metallic or neon pigments, providing a broad spectrum of beautiful, glossy finishes.
Polyurethane:
Nature: Polyurethane is described as a varnish-like coating that can be either oil or water-based. It is frequently used on wooden floors due to its ability to dry with various transparent finishes and create water-resistant surfaces.
Types of Floors:
Compatibility: Epoxy is highlighted for its compatibility with concrete, allowing it to be applied directly on top of old or worn concrete floors. Its self-leveling thickness is beneficial for filling and smoothing over cracks.
Appearance: Polyurethane, on the other hand, has a thinner dry film thickness, making it less effective at hiding existing blemishes.
Cost:
Factors: The overall cost depends on the size of the space and the number of layers needed. Epoxy coatings generally range from $2-$7 per square foot, while polyurethane coatings, though more expensive, offer longer durability, averaging around $3-$9 per square foot.
Labor: Labor, including floor preparation through cleaning and polishing, is a significant cost component.
Resistance:
Chemical Resistance: Both coatings resist chemicals, but polyurethane is noted for being more stain-resistant.
Surface Hardness: Epoxy creates a harder, more scratch-resistant surface, while polyurethane coatings are more elastic, offering enhanced impact and abrasion resistance.
Heat Tolerance:
Temperature Resistance: Epoxy coatings tolerate heat but soften above 120°F, losing their glossy finish. Polyurethane coatings withstand higher temperatures and are commonly used as a finish on top of epoxy flooring.
Food Industry:
Recommendation: Both coatings are approved for the food industry, but polyurethane is favored due to its longer lifespan, resistance to organic acids, thermal shock, and higher temperatures. Antimicrobial additives can be incorporated into polyurethane coatings for hygiene-sensitive environments.
Benefits:
Epoxy: Versatility in design, cost-effectiveness, and the ability to transform concrete floors into aesthetically pleasing surfaces.
Polyurethane: Shorter curing time, longer lifespan compared to epoxy, and imperviousness to staining from tires, making it suitable for garages.
Final Verdict:
Consideration: The choice between epoxy and polyurethane depends on the intended use of the floor and the specific conditions it will face. Sometimes, a combination of both coatings is recommended for optimal aesthetic appeal and protective features.
In conclusion, my comprehensive understanding of these coatings positions me to provide valuable insights, aiding individuals in making informed decisions for their flooring needs.
