Epoxy vs polyaspartic.
Two resins, not two rival floors. Here's what each one does well, where each falls short, and why most of the best Colorado garage floors use both.
01The short answer
Use each where it's strongest.
Epoxy is the workhorse. It bonds hard to diamond-ground concrete, builds thickness well and gives the installer time to work, which is why it's used for primers, base coats and metallic pours.
Polyaspartic is the fast, clear one. It cures quickly and holds up to sunlight without ambering, which makes it a great topcoat for a garage that has its door open half the summer.
A full-flake garage floor is a system: a base coat, the flake broadcast and a clear topcoat. Choosing epoxy, polyaspartic or a combination for each layer depends on your slab, the temperature and how you use the space. We recommend the combination for your floor at the free estimate.
02Side by side
How they compare.
- What it is
- EpoxyA two-part resin that cures hard and bonds strongly to ground concrete.
- PolyasparticA two-part aliphatic polyurea that cures fast and stays clear.
- Cure speed
- EpoxySlower. Longer before you can walk and park.
- PolyasparticFast. Floors are often back in use sooner.
- Sunlight (UV)
- EpoxyMany epoxies can amber over time in direct sun.
- PolyasparticUV-stable: stays clear with the garage door open.
- Working time
- EpoxyLonger working time, easier to build thickness.
- PolyasparticShort working time; takes experience to install well.
- Best role
- EpoxyPrimer and base coats, metallic pours.
- PolyasparticClear topcoats on flake and quartz floors.
03Colorado garages
What actually ruins garage floors here.
- 1
Bad prep
Neither resin survives on a slab that wasn't diamond-ground. Acid etching and roll-on kits leave a weak surface, and that's where peeling starts. - 2
Hot-tire pickup
Hot tires soften and grab thin, poorly bonded coatings. A ground slab, a proper build and a quality topcoat prevent it. - 3
Freeze-thaw & deicer
Snowmelt and mag chloride that get under a coating or into bare concrete freeze, expand and break the surface. A sealed, well-bonded floor keeps them on top.
Cost-wise, we price by system, not by resin. Our full-flake epoxy & polyaspartic system runs $6.25–$6.50 per sq ft. See the cost guide for every system.
04FAQ
Coating questions.
Don't see yours? Call and ask. That's what the phone's for.
Is polyaspartic better than epoxy?
Neither is better across the board. Epoxy bonds and builds well and gives a long working time; polyaspartic cures fast and stays clear in sunlight. Many of the best garage floors use both. We recommend the combination for your floor at the estimate.
Does epoxy turn yellow?
Many epoxies can amber over time with UV exposure, which is why garages that get a lot of sun through the door often get a UV-stable polyaspartic topcoat.
What is hot-tire pickup?
Hot tires soften and grab weak coatings, and when you pull away the coating lifts with the tire. It mostly happens with thin coatings on poorly prepped concrete. A diamond-ground slab with a quality topcoat is what prevents it.
Which one cures faster?
Polyaspartic. It's why polyaspartic floors can often be back in use sooner. Exact walk and drive times depend on the products and temperature; we give you yours at the estimate.
