7 Problems with Polyurea Floor Coatings

1. Costs More than Other Coatings

Chemline, a trusted industry supplier for nearly 30 years, calls polyurea “the premium coating option.” (source) Due to this status as premium, the most common issue with polyurea is the high price point.

However, the value of polyurea coatings is seen in both the long-term performance and efficiency of the product. They can be installed in one-day, but will last 15+ years. Unlike other flooring options, polyurea coatings won’t require regular replacement or costly regular maintenance. When looked at on a 15-year timeline, polyurea coatings cost more upfront, but less over time. This timeline is illustrated in the graph below, which shows a cost comparison of different garage flooring options over 15 years.

Over a period of 15-years, polyurea cost less than other flooring options.

For a space where you are looking for your floor to last for the long haul, investing in polyurea is a great choice. If you have a space where you want the most cost-efficient option just for right now, then other coating options may be the right fit for your budget and needs.

2. Different Product, Different Performance

Variations in the coatings marketed as polyurea lead to misconceptions about performance. Aromatic polyureas are light-sensitive and will fade with exposure. However, if used as a basecoat with an aliphatic polyurea topcoat, the coating is 100% UV stable. Polyurea polyaspartics will form a weaker surface bond to raw concrete (as a basecoat) that deteriorates over time. However, pure polyurea has a chemical bond that shows a level of adhesion above the industry standard, and a polyaspartic polyurea will function well as a topcoat.

When choosing a polyurea floor, knowing the details of the product can help you get the benefits you are looking for.

3. Professional Installation Required

Polyurea concrete coatings are not DIY-friendly. Coatings not installed by a professional lead to errors that can ruin the durability and longevity of your polyurea floor.

Polyurea concrete coatings have a narrow margin for error, and require high levels of precision. In fact, when consumers watch professionals install polyurea they describe it as a 'two-man dance' because of the efficient coordination that crews need when working with short cure times. Using the correct equipment and being fully educated about the mixing of polyurea compounds is needed to get the right result.

High-quality industrial-grade equipment is also necessary to properly prep a concrete surface for the application of polyurea. Without thorough grinding and mending of the floor, the concrete coating won’t successfully adhere to the surface and this impacts its performance.

To enjoy the benefits of polyurea as a coating, you should get your floor installed by a professional who gets their product from a reputable manufacturer and has the tools and experience to do a high-quality job.

4. Appears Slippery When Finished

Aliphatic polyurea topcoats, or pure polyurea coatings, are appreciated for their smooth and high-gloss finish. At a glance, it’s easy to feel concerned about the surface being slippery when wet. It’s required for outdoor and pool-side coatings to include a slip-resistant additive, but it’s also good to consider if this is useful in an indoor space. If you’re using your garage as a home gym, or want to coat your mudroom, choosing to include silica sand in your topcoat is a safe choice. Or, if you’re coating a steep surface like an inclined walkway.

There are two types of silica sand as options: 4095 heavy grit and a lighter, shark grip. Or, you can use a mixture.

5. When & Where Polyurea is the Right Choice

Polyurea is the best choice for both indoor and outdoor residential spaces. This includes garages, entryways/mudrooms, driveways, patios, and walkways. But we also see polyurea as an exceptional option for many commercial spaces. Polyurea is anti-porous, anti-chemical, and anti-microbial making it easy to clean in businesses like pet facilities, salons, or locker rooms. It’s also a way to repair commercial entryways, or walkways, in cold climates where exposed concrete can be damaged by the use of snowmelt and rock salt. In these situations, a coating with an anti-slip additive is a long-lasting and safe improvement.


6. Two Damages that Void the 15-year Warranty

A pure polyurea coating is incredibly durable, but not entirely indestructible. Although pure polyurea is likely the right choice for most residential and commercial spaces, it does have limitations. The two things that void your warranty are battery acid and metal-studded tires. These things won’t cause your coating to immediately crack or peel, but will erode the coating over time.

Beyond acid or tire studs, a polyurea concrete coating won’t hold failing concrete together. In the occurrence of a natural disaster that breaks your concrete and causes substrate failure, our coating won’t function as glue. Luckily, Webfoot Concrete Coatings can be called to repair any cracks and damage.

7. What Polyurea Can & Can’t Repair

As part of the installation process, normal wear and tear like cracking will be mended. But, there are a few things that polyurea can’t repair, like a crooked floor. Polyurea coatings are not self-leveling, because they are a thin coating that is absorbed into the pores of your concrete. Just like they won’t mend structurally failing concrete, they won’t level out your crooked floor.
