What Are The Disadvantages Of Polyaspartic Coatings

Thinking about using polyaspartic coatings but not sure about the downsides? We’ll walk you through the main cons of polyaspartic coatings.

Key Takeaways

• Polyaspartic coatings cost more to buy and install than other options like epoxy.
• These coatings can be slippery when wet, raising safety concerns in damp areas.
• They have few color choices, usually just light and medium grays.
• The coatings dry very fast, up to 15 times quicker than epoxy, making application tricky.
• Toxic fumes during installation require good air flow and safety gear to protect workers.

High Material and Installation Costs

Polyaspartic coatings cost more than other options like epoxy. Plus, skilled workers are required to apply them correctly, which bumps up labor costs.

While polyaspartic coatings offer great durability, their high price tag can be a real stumbling block. It’s important to weigh the long-term benefits against the upfront expense.

Vulnerability to Acid Corrosion

Polyaspartic coatings have a vulnerability to acid. These coatings contain amino acid molecules with weak bonding, making them susceptible to corrosion. This weakness can result in significant issues if the coating encounters acidic substances.

The effects of acid exposure can compromise both the coating’s appearance and its protective capabilities. This is a crucial consideration when selecting a coating for areas potentially exposed to acid spills or fumes.

Slippery Surface When Wet

Polyaspartic coatings can get really slippery when wet. This makes floors unsafe and raises the risk of people falling. It’s a huge concern in places that might get wet often, like bathrooms or kitchens.

There’s a fix, though. You can add non-stick properties to the surface, giving the floor more grip, even when it’s wet. But too much of this non-slip material can make the floor hard to clean. It’s all about finding the right balance between safety and easy upkeep.

Short Pot Life During Application

One significant challenge with polyaspartic coatings is their short pot life. These coatings dry extremely quickly, up to 15 times faster than epoxy. While rapid drying can be advantageous, it can also create issues during application.

You have a limited timeframe to work with the material before it begins to harden. This urgency can result in errors and inconsistent coverage. Your team needs to be swift and proficient when applying polyaspartic coatings.

Potential Bonding Issues with Concrete

Polyaspartic coatings can be picky about where they stick. They don’t play nice with wet floors or high-moisture areas.

It’s a struggle to use polyaspartic coatings in damp spots, which limits their use. The coating’s bond to concrete can also get weak if the temperature isn’t just right during installation. We always have to be extra careful when applying these coatings to make sure they bond well.

Toxic Fumes During Installation

Polyaspartic coatings coatings give off harmful chemicals that can make you sick if you breathe them in. That’s why it’s so important to have good air flow and wear safety gear when putting them on. The fumes contain VOCs, which are bad for our health and the environment.

We must take extra care to protect ourselves and others nearby when using these coatings. Always use special masks, gloves, and clothes to avoid touching or breathing in the chemicals. It’s crucial to keep the work area well-ventilated, with fans and open windows if possible.

Conclusion

Polyaspartic coatings are strong, long-lasting, and dry super fast—but like anything, they have a few downsides. They cost more, can be slippery when wet, and need to be installed just right. There are also some safety concerns during installation because of the strong fumes.

But don’t let the cons scare you off. When installed correctly, polyaspartic coatings look great and hold up really well over time. Every product has its disadvantages, but the benefits of polyaspartic often make it worth it. Just make sure you work with experienced installers who know how to handle it safely and properly.
