Epoxy Vs. Polyurea: Which Is Better For A Concrete Coating?

An experiment in chemistry is like a coating on concrete. To produce what is intended to act as a protection for concrete, several substances and materials are blended together.

Some chemicals are more resistant to the effects of the environment and stronger than others. Any concrete surface that is coated should be durable, long-lasting, and able to provide protection.

Concrete Coatings are an investment, and if you pick the incorrect product for a concrete coating, you’ll encounter issues earlier than you anticipated that will cost you more time and money in the future. C&E Concrete Coatings provides a polyurea concrete coating with vinyl chips and Polyaspartic topcoat that can be customized. This product has a 15-year warranty and is incredibly durable. 

Although we exclusively provide polyurea coatings because of its superiority, toughness, and lifespan, an epoxy coating can still be the better option for you. Epoxy is a cheap and very simple substance for a rapid coating. In this post, we’ll contrast its most well-known rivals, epoxy, with a polyurea concrete coating. We’ll consider factors including price, preparation time, cure rate, and durability. 

After reading, you will have a clearer grasp of the key distinctions between polyurea and epoxy, enabling you to choose the correct coating for your concrete when the time comes. 

We must first clearly define epoxy and polyurea before making any comparisons.

What is epoxy?

A kind of polymer is epoxy. A polymer is a substance comprised of big molecules that have been repeatedly linked together. Polymers are frequently utilized in building because of their elastic and durable nature.

Wool, DNA, fingernails, and hair are more examples of polymers. 

A resin and a hardener make up an epoxy mixture used for concrete coatings. In order to connect with the concrete, the two are combined and uniformly dispersed across the surface.

Epoxy coatings can be compared to paint in appearance. It does not affix itself to the concrete’s surface or grow roots through it.

What is polyurea?

In addition to being a form of polymer, polyurea is also an elastomer. This indicates that it is a synthetic rubber-like polymer. 

Compounds made of polyurea can be designed to have a wide variety of hardness and other characteristics. It is a common compound for concrete coating because it can be tailored to boost strength and flexibility. 

Now that you know what epoxy and polyurea are, we can compare the advantages and disadvantages of these two widely used concrete coating substances.

How do polyurea and epoxy compare to one another?

It is difficult to determine how these materials compare to one another and how they hold up when viewed from the outside. There are many possibilities available. 

In what way do you choose between two options? You weigh their benefits and drawbacks. What makes the one you select superior to the other and how is it superior to the other? 

By the time you finish reading this post, you will be able to choose between epoxy and polyurea based on the most critical characteristics to compare.

Durability

Epoxy’s durability is well recognized and actively promoted. It can tolerate tire marks, chemicals, stains, scratches, and general impact for a garage floor coating. 

However, the heat from your tires can eventually wear away the epoxy if you often pull into your garage after a lengthy trip. 

In outdoor spaces, UV heat will also wear down and cause the epoxy to turn yellow.

As for polyurea because it is an elastomer, polyurea is more flexible and more enduring than epoxy. According to Corrosionpedia, it is also chemically resistant and capable of withstanding heat up to 266°F and 430°F for a shorter period of time.

Due to it’s UV resistance, polyurea won’t tan in the sun. Because of this, polyurea is a fantastic material for sidewalks, driveways, and pool decks that are outside. 

In conclusion, due to its strength against spills, scratches, and impacts as well as its heat and UV resistance, polyurea is more durable than epoxy.

Longevity

When discussing durability, epoxy and polyurea’s lifetime is a natural topic of discussion. 

The average lifespan of an epoxy coating is three to five years before you start to see wear and degradation. As a result, you will need to change that coating more frequently than you would with a polyurea coating, which will take more time and money.

The lifespan of polyurea is around 15 years since it is more resilient than epoxy.

This item is created to last a lifetime.

Taking everything into account, polyurea will outlast epoxy by at least ten years.

Cost

You can get epoxy, a popular DIY material, from your neighborhood hardware shop. Typically, it costs $3 to $7 per square foot, although some epoxy coatings may reach upwards of $12.

Polyurea coatings will cost more than epoxy coatings since they are more resilient and will last longer. 

C&E Concrete Coatings charges roughly $2,200 on average for a 2 stall garage polyurea/polyaspartic concrete coating. Around $5–$7 per square foot is what it costs.

Even though polyurea costs more than epoxy, you get greater value for your money because of its resilience and long lifespan.

Work in preparation

Both epoxy and polyurea concrete finishes call for meticulous concrete preparation. 

A concrete surface can be smoothed down with sandpaper to prepare it for epoxy, although concrete grinding/etching is a more common technique.

The first step in preparing a surface for a polyurea coating is to fill up any cracks, pits, or hollow areas. The surface of the concrete is next leveled and smoothed with a diamond grinder.

Cure time The cure time is the period of time needed for the product to completely harden.

Depending on where your concrete coating is, epoxy might take up to five days to fully cure, which can be quite inconvenient for you. 

Our polyurea coating cures in one day, allowing for 24-hour parking and 12-hour walk on time. 

It is crucial to remember that temperature and humidity will have an impact on the curing time. In general, a surface will heal more quickly in hotter climates and more slowly in more humid ones.

Volatile organic compounds, or VOCs, release during coating applications and produce a stench in the air. Even though epoxy and polyurea are both thought to have minimal levels of volatile organic compounds (VOCs), the scent persists while the materials are curing.

In comparison to epoxy, a polyurea coating will allow you to cut days off the cure period.

Customizability

Everyone enjoys having alternatives, so if you like to make your house uniquely yours, you’ll want to customize whatever purchase you make. 

You may select from a variety of colors for both epoxy and polyurea. 

You never know what color options you will have if any, depending on whether you are utilizing epoxy for a do-it-yourself concrete coating or hiring a professional.

You have countless possibilities for personalizing the color of chips you want on your floor and the quantity of each color when utilizing the Penntek polyurea coating’s chip system.

Which is superior, polyurea or epoxy?

Polyurea is a preferable option if you want your concrete coating to be strong and require little maintenance.

A less costly epoxy alternative would be preferable for you if all you want to do is tidy up the garage before you leave your house shortly. What matters most in terms of selecting a product are your demands and objectives. 

Another factor in choosing the right product/company is prep work whether you choose epoxy or polyurea, a poorly prepped/installed coating won’t hold up very long! 

Your polyurea concrete coating will survive with C&E Concrete Coatings thanks to its 15-year product warranty and our lifetime warranty if you experience any problems. What is essential to us is exceptional craftsmanship, as well as quality goods and services.

Why Polyurea Over Epoxy

This article provides you with five significant reasons you should consider Polyurea over epoxy. Looking at the extreme similarities between Polyurea and epoxy, you’re probably confused about what’s best for you. Thankfully, you’ll know the truth as you continue reading what our expertise here at C&E Concrete Coatings has found to be true. 

5  Reasons Polyurea is a Better Choice Over Epoxy

If all the surrounding sources claim Polyurea is a better choice, guess what? They are right and here are five significant reasons Polyurea coating is the best for you.

1. Chemical Composition

Long life’s plan is in place when you use polyurea. This is because the coating has a robust chemical composition got from ability in polymer science. Therefore, they can endure strong mechanical forces and heavy traffic without causing as much as a scratch on the surface.

What’s more? This coating material has a complex chemical makeup that adds to its outstanding endurance. The chemical process of polyaddition is utilized to rapidly merge synthetic resins and isocyanates.

Epoxy coatings harden differently than Polyureas, which go through a faster process called gelation. This gelation process allows the formation of chemical bonds in a matter of seconds. Which results in the making of a strong and cross-linked network.

2. Molecular Structure

The two-component reaction used to produce Polyurea comprises the isocyanate and the amine. This aids in creating a cross-linked polymer network.

Their network’s structure is composed of long chains and flexible urethane groups. Hence, this configuration gives polyurea its extraordinary flexibility and extensibility.

Polyurea can disperse stress throughout the entire surface area when external forces are applied. As opposed to focusing it in certain places, such as substrate movements or vibrations. 

Therefore, this homogeneous stress distribution prevents peeling or cracking. Besides providing long-lasting adhesion and security.

3. Waterproofing

Polyurea coatings are known for their waterproofing properties, which make them unique. Here’s how its waterproofing capabilities make it worth it: It acts as an efficient barrier against moisture-related problems like leaks or corrosion.

So, in locations where there’s a significant likelihood of heavy rain or high humidity, this impermeable membrane serves as a dependable barrier. 

Due to intrinsic flaws in epoxy coatings, such as cracks or pinholes that may appear during application or substrate movement. They are sometimes vulnerable to water penetration.

4. Presence of Specialized UV

Due to specialist UV stabilizers in Polyurea composition, they show remarkable resistance to UV light. Their stabilizers stop the coating film from degrading because of prolonged solar exposure.

Polyurea coatings keep their color stability and gloss retention over a longer period by absorbing and dispersing UV radiation. This is another reason they’re best for outdoor applications where there’s constant exposure to the sun.

Epoxy coatings are susceptible to UV deterioration. They can become discolored, fade, and lose their original sheen after prolonged exposure to sunlight’s self-leveling healing properties.

5. Self-leveling

Epoxy coating’s ability to withstand moisture intrusion can get jeopardized by even minor flaws. This is where the self-leveling capabilities of polyurea come in handy. Polyurea unquestionably performs better than epoxy in several areas because of the coating’s resilience to environmental influences.

Long-term durability and protection are ensured by Polyurea’s capacity to tolerate extreme weather conditions. This includes intense heat and bitter cold. Additionally, the UV stabilizers increase its resilience to fading and sun damage.

Conclusion 

It doesn’t matter the purpose of the floor: basement, garage, patio, or walk away. If you want great value for your money, choosing Polyurea over epoxy is the right option.
