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.


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.
