Polyurea vs. epoxy: Which concrete coating is best?


Polyurea vs. epoxy:
 Which concrete coating is best? 

Concrete coatings are similar to chemistry experiments. Concrete coatings are made up of different elements and compounds that combine to form a protective shield.

Certain compounds are stronger and can withstand more outside elements than others. You want concrete surfaces coated that will protect, last, and be durable.

Like all home improvements projects, concrete coatings are not something you can afford to pay for with spare change.

Concrete coatings are an investment. If you pick the wrong product, you will run into problems that can cost you more time and money.

ArmorThane offers a concrete coating product that is extremely durable and can be used immediately. 

Their experts can tell the difference between high-quality concrete coating materials and those that won't last. With over 30 years as an industry leader, 9- you can rest assured that you will get the best product and install available on the market.

We recommend polyurea coatings for their durability, quality, and long-term performance. However, an epoxy coating could be the right choice for you if the situation calls for it. If you need a quick coating, epoxy is an affordable and simple material.

This article will compare ArmorThane's polyurea concrete coating with epoxy. We'll be looking at aspects such as cost, preparation, cure time, durability, and maintenance. 

This article will help you understand the differences between epoxy and Polyurea to make an informed decision about the concrete coating you desire.

Before we can compare the two, it is important to understand what epoxy and Polyurea are.

What is epoxy?

A polymer is made up of large molecules that are strung together repeatedly. Polymers are used for construction because of their flexibility and toughness. One type of polymer is epoxy.

Another example of polymers is wool, DNA, and fingernails.

A resin and hardener are the two main components of an epoxy mixture for concrete coatings. Mix the two ingredients and then spread them evenly on the concrete surface.

An epoxy coating can be compared to paint. It is placed on top of concrete and does not bond to roots.

What is Polyurea?

Polyurea can also be a type of polymer, but it can also be an elastomer. It is a synthetic polymer with rubber-like properties.

Polyurea compounds are versatile and can be made to have a variety of properties and hardness levels. You can customize them to improve strength and flexibility, making them a popular choice for concrete coatings.

We now understand epoxy and Polyurea so that we can compare the characteristics of these popular concrete coatings.

What do epoxy and Polyurea compare?

It isn't easy to compare these materials and see how they stack up against each other from the outside. There are many options available, just like any other decision.

How can you choose between two things? It is important to consider their pros and cons. Which is better? And which one do you prefer?

We will show you the key qualities of epoxy and Polyurea. By the end, you'll know exactly what concrete coating you need.


Epoxy is well-known for its durability and is often advertised. Epoxy can be used as a garage floor coating and is resistant to chemicals, scratches, dirt, and other impacts.

But, if your tires are always being driven, you will eventually wear the epoxy.

UV heat can also cause yellowing of epoxy in outdoor areas.

Polyurea is stronger than epoxy and is also more flexible, as it is an elastomer. It can withstand high temperatures up to 266 degrees Celsius and 430 degrees Celsius for a shorter time, according to Corrosionpedia.

Polyurea has UV resistance and won't yellow in the sunlight. It is a great choice for patios, pools decks, driveways, and sidewalks.

Polyurea is stronger than epoxy due to its heat resistance and UV resistance. It also resists spills, scratches, and impacts.


When talking about durability, epoxy and Polyurea are naturally discussed.

Most epoxy coatings last between three and five years before they start to wear. Polyurea coatings will take longer and cost more.

Polyurea has a 15-year life expectancy because it is stronger than epoxy.

This product is made to last a lifetime.

Polyurea will last at least ten years longer than epoxy.


For DIY jobs, epoxy is a popular product that you can find at your local hardware shop. Typically, epoxy costs between $3-7 per square foot. However, some epoxy coatings can go as high as $12.

Polyurea coatings will be more costly than epoxy because they are more durable and last longer.

The average cost for a single-bay garage with a polyurea concrete coating is approximately $2,000. The average cost for a single-bay garage polyurea concrete coating with Polyurea is about $2,000.

Polyurea may be more expensive than epoxy, but you get the durability and longevity that you deserve.

Prep work

Special preparation is required for both epoxy and polyurea concrete coatings.

Preparing concrete surfaces for epoxy may involve sanding them smooth or acid etching.

Acid etching involves using a mixture of acid (typically hydrochloric acid and phosphoric acid) to scrub the surface. This is the best option for a DIY job, but it is still very popular in the professional sector.

Acid etching, like all chemicals, can pose a risk to your health. If not done properly, acid etching can cause irreparable damage to concrete and your body.

The preparation of ArmorThane polyurea coating begins with filling any cracks, pits, or hollow spots. If the concrete is too wet or soft, a densifier can be added. To smoothen and even out the concrete, a diamond grinder is used.

The two types of epoxy are very similar depending on which preparation is used. Acid etching is a potentially dangerous and harmful preparation technique.

Cure time

The product's cure time is the time taken for it to harden completely.

It can take epoxy up to five days for it to fully cure, which can be very frustrating depending on where your concrete coating is located. 

The ArmorThane polyurea coating can be applied in just one day. You can then walk on it for six hours and park your car on it for 24 hours. 

It is important to remember that humidity and temperature can affect the time it takes to cure. It is faster for hot surfaces to heal, while it takes longer for damp surfaces to heal.

VOCs (volatile organic compounds) are released during coatings. They leave a lingering smell in the air. Although VOCs in epoxy and Polyurea are low, they can still be detected during curing.

If epoxy cures in five days, then the scent of coating chemicals will still be present simultaneously.

Polyurea coatings are going to save you time and cut down on the cure time.

You can customize

Everybody loves options. If you want your home to be unique and individual, you will need to personalize everything you invest in.

You have a variety of color options when it comes to epoxy and Polyurea. 

You don't know which color options you might have depending on whether epoxy is used for DIY concrete coatings or professional installation. Professional installers can offer epoxy with a similar chip system and custom colors.

You can customize the colors and amounts of the chips that you place on your floor with the ArmorThane polyurea system using the chip system.

Which one is better, epoxy or Polyurea.

It isn't easy to pick a winner when comparing two products. Polyurea is the better concrete coating. It cannot be easy to choose between two products.

If your goal is to move out soon, you can choose a cheaper epoxy product.

The installation is an important part of deciding which product is best for you. A poor installation will not last, no matter what coating you choose, epoxy or Polyurea.
