Every epoxy flooring system is only as strong as its topcoat. While primers bond the system to the concrete and midcoats build thickness and design, the topcoat is what protects everything underneath. It’s the layer that takes on scratches, UV rays, chemicals, spills, and daily traffic so your floor stays beautiful and durable for years.
At PNA Coatings, we treat the topcoat as the most important step in the process. A properly chosen and applied topcoat ensures:
Skipping the right topcoat or cutting corners at this stage can mean a floor that looks good at first but fails too soon. That’s why every project we install ends with a professional-grade protective finish — the key to a floor that doesn’t just look amazing on day one but performs for years to come.
Aliphatic urethane topcoats have a glass-like gloss finish with a slight orange-peel texture that hides imperfections well. They are available in gloss, satin, or matte finishes, making them versatile for different looks. The odor is moderate during application, but it fades quickly once cured. Because of their UV stability, they hold color well without yellowing, even in brighter areas.
Ceramic gel coats are all about high-gloss, mirror-like shine. This is the shiniest option available, often chosen when the goal is a dramatic showroom or social media-ready look. These coats are usually only available in high gloss (not matte or satin), and they do not offer strong UV resistance. The smell is stronger during spraying but does not linger long after curing.
Water-based urethanes are a low-odor option, making them a favorite for indoor projects where ventilation might be limited. They can be applied in gloss, satin, or matte finishes, giving you flexibility based on the look you want. While they have a slight texture finish, they are great for spaces that want a natural, subtle shine without overwhelming gloss.
Polyaspartic topcoats are known for their brilliant gloss finish and can also be produced in satin or matte options depending on project needs. They cure very quickly, so installers must work fast, but once down, they create a rock-solid, UV-stable finish that won’t yellow. The smell during application is noticeable but short-lived because of the fast cure times. This makes them excellent for garages, patios, and outdoor spaces that see a lot of sunlight.
Concrete sealers are a cost-effective protective option for bare or lightly finished concrete floors. They are available in gloss, satin, and matte sheens, giving flexibility depending on the desired look. Odor levels are generally low to moderate, depending on the type (acrylics vs. penetrating sealers). While not as durable as polyaspartics or urethanes, they are great for warehouses, basements, garages, or industrial floors where dusting and stains need to be controlled. Some sealers also come with UV-resistant formulas for outdoor use, though reapplication is more frequent.
A glossy epoxy floor looks amazing, but smooth surfaces can sometimes become slippery, especially in garages, kitchens, pool decks, or commercial areas where water, oil, or other spills are common. That’s where anti-slip additives come in. These additives are mixed into the topcoat or broadcast across the surface to create just the right amount of traction without taking away from the floor’s appearance.
At PNA Coatings, we typically use aluminum oxide, silica sand, or decorative vinyl flakes as anti-slip options. Aluminum oxide is the toughest, giving industrial-grade slip resistance that can handle heavy traffic, forklifts, and wet conditions. Silica is a more economical choice, adding grip without changing the look much. Vinyl flakes provide both texture and design, blending safety with style.
Anti-slip floors require a little more attention during cleaning since dirt and debris can cling to textured surfaces. It’s also important to remember that while these additives greatly reduce the risk of slipping, no floor can ever be made completely slip-proof. Choosing the right system ensures the perfect balance of safety, durability, and appearance.
