Polyaspartic Coating: A Comprehensive Guide

What Is Polyaspartic Coating?

Definition and Composition

Polyaspartic coating is a type of polyurea that is widely used for its fast-curing and durable properties. It is composed of aliphatic polyisocyanate and a polyaspartic ester, which react to form a highly resilient and flexible coating. This unique composition allows it to be applied in various environments and conditions, making it a versatile choice for many applications.

How It Works

Polyaspartic coating works by creating a chemical reaction between the polyisocyanate and the polyaspartic ester. This reaction forms a strong, flexible, and durable layer that adheres well to various surfaces. The coating can be applied in multiple layers to achieve the desired thickness and finish.

Common Applications

Polyaspartic coatings are used in a variety of settings due to their durability and fast-curing properties. Common applications include:

Pros and Cons of Polyaspartic Flooring

The Pros of Polyaspartic Flooring


Polyaspartic flooring is known for its longevity. It can withstand heavy traffic and harsh conditions without showing signs of wear and tear.

Fast Drying

One of the standout features of polyaspartic coating is its fast drying time. This allows for quicker project completion and less downtime.


Polyaspartic coatings are considered eco-friendly due to their low VOC (Volatile Organic Compounds) content. This makes them a safer choice for both installers and the environment.

Resistant to Chemicals

Polyaspartic coatings are highly resistant to chemicals, making them ideal for industrial and commercial settings where spills and exposure to harsh substances are common.

Year-Round Installation

Unlike some coatings that require specific temperature conditions, polyaspartic coatings can be applied year-round, making them a versatile option for various climates.

The Cons of Polyaspartic Flooring

Limited Color Options

One of the drawbacks of polyaspartic flooring is the limited color options available. This can be a disadvantage for those looking for a specific aesthetic.

More Expensive

Polyaspartic coatings tend to be more expensive than other types of flooring, such as epoxy. This can be a consideration for budget-conscious projects.


When wet, polyaspartic flooring can become slippery, posing a potential safety hazard. This is something to consider, especially in areas prone to moisture.

Polyaspartic Coating vs. Epoxy

Drying Time

Polyaspartic coatings have a significantly faster drying time compared to epoxy. This allows for quicker project completion and less downtime.


Both polyaspartic and epoxy coatings are durable, but polyaspartic tends to have a longer lifespan and better resistance to wear and tear.

UV Stability

Polyaspartic coatings offer superior UV stability, making them ideal for outdoor applications where exposure to sunlight is a concern.

Common Problems with Polyaspartic Coatings

Problem #1: Bonding Issues with Concrete

Bonding issues can occur if the concrete surface is not properly prepared before applying the polyaspartic coating. This can lead to peeling and poor adhesion.

How to Avoid Bonding Issues

To avoid bonding issues, ensure that the concrete surface is clean, dry, and free of contaminants. Proper surface preparation is key to a strong bond.

Problem #2: Air Bubbles in the Coating

Air bubbles can form in the polyaspartic coating if it is applied too quickly or if the surface is not properly prepared.

How to Avoid Air Bubbles

To prevent air bubbles, apply the coating slowly and evenly. Make sure the surface is smooth and free of imperfections.

Problem #3: Partial Evaporation of Coating

Partial evaporation can occur if the coating is applied in very hot or windy conditions, leading to an uneven finish.

How to Avoid Evaporation Issues

To avoid evaporation issues, apply the coating in controlled conditions. Avoid extremely hot or windy days.

Problem #4: Improper Mixing Ratios

Improper mixing ratios can lead to a weak or ineffective coating. It’s crucial to follow the manufacturer’s instructions precisely.

How to Ensure Proper Mixing

To ensure proper mixing, use the exact ratios specified by the manufacturer. Mix thoroughly to achieve a consistent blend.

Problem #5: Fading Over Time

Fading can occur if the polyaspartic coating is exposed to harsh UV rays without proper UV stabilizers.

How to Prevent Fading

To prevent fading, choose a polyaspartic coating with UV stabilizers. Regular maintenance can also help preserve the color.
