As someone deeply committed to improving epoxy floor longevity and performance, I’ve witnessed how urethane top coat for epoxy transforms surfaces. Let’s delve into these benefits further.

Benefits of Urethane Top Coats for Epoxy
When it comes to protecting and enhancing your epoxy floors, urethane top coats are a game-changer. Let’s explore the key benefits that make them a must-have for your flooring projects.
Chemical Resistance
First and foremost, urethane top coats offer superior chemical resistance. This is crucial for spaces like garages, commercial kitchens, and industrial areas where spills and splashes are frequent. Urethane creates a barrier that protects the epoxy layer beneath from oils, acids, and other harsh chemicals. This not only prolongs the life of your floor but also reduces maintenance costs over time.
Abrasion Resistance
Urethane top coats are known for their exceptional abrasion resistance. In fact, they offer up to three times more abrasion resistance than epoxy alone. This is especially important in high-traffic areas such as retail stores, sports arenas, and automotive service areas. The urethane layer absorbs the impact of foot traffic and heavy equipment, keeping your floors looking pristine for years.
UV Stability
One of the standout features of urethane top coats is their UV stability. Unlike some other coatings, urethane doesn’t yellow or degrade when exposed to sunlight. This makes it ideal for spaces with lots of natural light or outdoor exposure. Whether you’re working on a sunlit showroom or an open-air patio, a urethane top coat ensures that your epoxy floor maintains its original color and finish.

Improved Aesthetics
Beyond protection, urethane top coats also improve the visual appeal of your floors. They come in various finishes—gloss, satin, and matte—allowing you to choose the look that best suits your space. A glossy finish can give your floor a sleek, modern appearance, while a matte finish offers a more understated, neat look.
In summary, urethane top coats are a vital addition to any epoxy flooring project, offering best chemical and abrasion resistance, UV stability, and aesthetic flexibility. Whether you’re upgrading a commercial space or a residential garage, urethane top coat for epoxy is the key to long-lasting, beautiful floors.
Let’s move on to how you can choose the right urethane top coat for your specific needs.
Choosing the Right Urethane Top Coat
Selecting the right urethane top coat for epoxy is crucial for ensuring the longevity and appearance of your floors. With several options available, it’s important to understand the unique features and benefits of each to make an informed decision. Let’s explore four popular choices: TL321, TL322, Leggari WB Urethane, and Chargar High Performance 322.
TL321: The High-Performance Choice
TL321 stands out as a top-tier aliphatic urethane, known for its exceptional performance. It boasts the highest ratings in abrasion and chemical resistance, making it perfect for demanding environments. However, due to its composition, it cannot be shipped to certain areas, which might limit its availability.
TL322: Compliance and Performance
For those who need a urethane that meets various VOC regulations, TL322 is a great option. While it may not match TL321 in every aspect, it still exceeds many competitors in performance. Its ability to comply with strict laws while maintaining quality makes it a versatile choice for both commercial and residential projects.
Leggari WB Urethane: Water-Based and User-Friendly
Leggari WB Urethane is a water-based formula, making it easy to apply with minimal odor. It’s 100% UV stable, ensuring no yellowing over time, and offers both gloss and matte finishes. This product is ideal for DIY enthusiasts and professionals alike, thanks to its ease of use and quick recoat time. Plus, the optional grit additive provides improved scratch and slip resistance, perfect for more demanding environments.
Chargar High Performance 322: Versatility and Strength
Chargar High Performance 322 is a two-component polyester/aliphatic polyurethane that excels in flexibility and UV stability. It’s suitable for a wide range of applications, from auto service centers to laboratories. Available in both clear and colored options, it offers versatility in design. Adding fine aggregate additives like silica sand or aluminum oxide can further improve slip and wear resistance, making it a robust choice for various settings.

In conclusion, choosing the right urethane top coat depends on your specific needs and environmental considerations. Whether you prioritize chemical resistance, ease of application, or compliance with regulations, there’s a urethane top coat custom for you.
Next, we’ll dive into the application process and share tips for achieving the best results with your chosen urethane top coat.
Application Process for Urethane Top Coats
Applying a urethane top coat for epoxy can seem daunting, but with the right steps, you can achieve a professional finish. Here’s a simple guide to get you started.
Mixing Instructions
Mixing your urethane top coat is crucial for a smooth application. Most products, like the One Stop Epoxy Urethane – WB, come in a two-component system. You’ll need to mix three parts of the urethane resin to one part of the catalyst by volume.
- Partial Kits: If you’re not using a full kit, ensure you maintain the 3:1 ratio. Mix at a low speed for two minutes to avoid air bubbles.
- Full Kits: Pour the catalyst into the pre-measured resin and stir with a jiffy mixer for two minutes.
Tip: Add 8-10 oz of water to improve usability and smoothness.
Application Tips
Once mixed, your urethane can be applied using a 3/16” nap roller. Here’s how:
- Dip and Roll: Evenly dip and roll the mixed material to maintain the desired thickness.
- Back Rolling: This step ensures a uniform finish. It helps distribute the coating evenly across the surface.
Temperature Alert: Apply when temperatures are between 55-90°F for the best results.
Grit Additive
For areas requiring extra slip resistance, consider adding a grit additive like aluminum oxide. This can be especially useful in high-traffic or wet areas. Simply mix the grit into your urethane before application.
Coverage and Dry Time
- Coverage: Expect 400-600 sqft per kit, depending on the type of floor.
- Drying Time: Your floor will be tack-free and ready for foot traffic in 6-8 hours. For heavy foot traffic, wait 48 hours, and for vehicular traffic, allow 3 days.
Remember: Lightly sand the surface and wipe with denatured alcohol or acetone before applying additional coats.
Following these steps ensures your epoxy floors not only look great but also last longer with a durable urethane top coat. Next, we’ll answer some frequently asked questions about urethane top coats for epoxy to clear up any lingering doubts.
Frequently Asked Questions about Urethane Top Coats for Epoxy
Can you put urethane on top of epoxy?
Absolutely! Applying a urethane top coat for epoxy is a common practice because it improves the durability and appearance of your floors. One of the major benefits of urethane is its UV resistance. Unlike epoxy, which can yellow over time when exposed to sunlight, urethane remains clear and stable. This makes it an excellent choice for areas with significant sunlight exposure.
Urethane also adds flexibility to the surface. This flexibility helps the floor withstand impacts and heavy loads, making it ideal for commercial spaces like warehouses and garages.
What’s the best top coat for epoxy?
When it comes to choosing the best top coat for epoxy floors, TL321 is often recommended. It is a high-performance urethane known for its exceptional chemical resistance. This means it can withstand spills from oils, acids, and other harsh chemicals, making it perfect for industrial settings.
However, TL321 might not be available in all areas due to shipping restrictions. In such cases, TL322 is a great alternative. It complies with many VOC laws while still offering superior protection compared to many other products.
What kind of clear coat can I put over epoxy?
If you’re looking for a clear coat to apply over epoxy, polyurethane coatings are an excellent choice. They offer a combination of wear resistance and abrasion resistance that is three times higher than epoxy alone. This makes them suitable for high-traffic areas where durability is a priority.
Polyurethane coatings not only protect against scratches and wear but also provide a glossy finish that improves the visual appeal of your floors. Whether you’re coating a garage, showroom, or commercial space, polyurethane can provide the protection and finish you need.
