Epoxy vs polyaspartic
Both are two-part resins that cure into a hard, chemical-resistant floor. They differ in how fast they cure, how they handle sunlight and how thick each coat builds.
| Polyaspartic | Epoxy | |
|---|---|---|
| Cure time before parking | About 24 to 48 hours | About 72 hours |
| Sunlight and UV | Stays clear, does not yellow | Can amber in direct sun without a UV-stable topcoat |
| Thickness per coat | Thinner, built in more coats | Thicker in a single coat |
| Temperature range for install | Cures in cooler conditions | Needs a warmer slab |
| Price | Higher per square foot | Lower per square foot |
| Where it shines | Garages you need back fast, patios, sun-exposed spaces | Metallic floors, thick base coats, budget builds |
Common questions
Can you combine epoxy and polyaspartic?
Yes, and it is common. An epoxy base coat builds thickness at a lower cost, and a polyaspartic topcoat adds UV stability and scratch resistance.
Which lasts longer?
Both last for many years when the slab is prepared properly. Prep has a bigger effect on how long a floor lasts than the choice between the two.
